SYSTEMS AND METHODS FOR DETERMINING A HUMIDITY SET POINT Field [0001] This disclosure generally relates to habitable environments and indoor spaces such as, for instance, homes, apartments, hotels or motels, offices, event spaces, meeting spaces, schools, and hospitals, etc., as well as rooms or other indoor spaces therein and particularly to methods, devices, and systems for analyzing humidity and determining a humidity set point and humidity set point range for an indoor space. Background [0002] Most people often spend significant amounts of time in habitable environments or other indoor spaces such as enclosed spaces associated with homes, apartments, condominium units, hotel suites or rooms, motel suites or rooms, spas, hospitals, offices, commercial spaces, and other public and private facilities. Sometimes these enclosed spaces may be operated or controlled, or even owned by, the principal occupants, such as homes, apartments or condominium units. Other times these enclosed spaces may be operated or controlled by others, for example a facility owner or operator who may own and/or operate a hotel, motel, spa, hospital. [0003] Humidity in an indoor space often is related to the amount or degree of moisture in the air, and often is measured as the amount of water vapor in the air in the indoor space. The higher the humidity, the higher the amount of water vapor in the air. A humidity level in an indoor space can be impacted by many factors, such as the climate where the indoor space is located, the availability or use of a heating, cooling, dehumidifying, humidifying or other air related handling or processing system or device in the indoor space, temperature within the indoor space, etc. [0004] Typically, three different types of humidity measurements often are used. Absolute humidity is the total amount of the water vapor in a certain amount of air and is expressed in grams of moisture per cubic air. Relative humidity is a percentage that indicates the relationship of absolute humidity at a temperature to the maximum possible humidity at the same temperature. Specific humidity is the mass of water vapor in a unit mass of moist air and is expressed in grams of moisture per kilogram of moist air. [0005] There are also other metrics that can be used to quantify the amount of the water vapor in the air. For example, the dew point is the temperature to which air must be cooled to become saturated with water vapor. When cooled further, the water vapor in the air will condense to liquid water. The lower the dew point is, the lower moisture is contained in the air, and vice versa. [0006] The humidity level in an indoor space can have an impact on the indoor space itself, as well as on an occupant in the indoor space. For example, the humidity level in an indoor space may impact the plants and other biophilia in the indoor space, the amount of static electricity in the indoor space, the thermal conductivity of the air in the indoor space, the condition of wood panels or paint in the indoor space, the artwork, books or other items, in the indoor space, etc. [0007] When indoor spaces are subjected to high humidity conditions for long periods of time, microorganisms such as mold, fungi, and bacteria can grow on building materials and furnishings in the indoor space. As a result, indoor concentrations of airborne mold spores can increase significantly in the indoor space. Inhaling or touching mold or mold spores may cause allergic reactions such as stuffy nose, wheezing, and red or itchy eyes, while people with chronic respiratory diseases (e.g., a chronic obstructive pulmonary disorder or asthma) may experience difficulty breathing. [0008] High humidity in an indoor space may also lead to condensation on surfaces in the indoor space. Such condensation can corrode critical structural fasteners inside the walls, foundation, and roof of a building. Severe damage caused by condensation also may result in safety issues, which may require mold remediation work. [0009] In regard to human health and wellness, the humidity level in an indoor space also may impact the comfort level of one or more occupants of the indoor space, the transmission of respiratory viruses, such as the cold and flu, in the indoor space, etc. Many people also may experience discomfort when humidity is high. However, extremely low humidity also can lead to thermal discomfort by drying a person’s skin and mucous surfaces, resulting in dry nose, throat, eyes, and skin. [0010] Dry air in an indoor space can promote the movement of viruses in the air in the indoor space and also negatively impact a person’s upper respiratory defense mechanisms from protecting the person against pathogens, including viruses. Furthermore, both very dry (e.g., 20% relative humidity) and very humid (e.g., 80% relative humidity) environments can increase the transmission of respiratory viruses. Maintaining moderate indoor relative humidity levels between 40% and 50% often will help reduce the risk of virus transmission indoors and promote better indoor air quality. [0011] A person’s immune system often is a significant defense for the person against various pathogens. The performance of the person’s immune system can be affected by many factors, including humidity. When the air is dry, the effectiveness of the person’s upper respiratory defense mechanisms in protecting the person’s body bodies from pathogens, including viruses, can be reduced. Dry air can also dry out the person’s nasal passages, which can slow the rate at which viruses and other pathogens are cleared out from the respiratory tract, thereby increasing the person’s susceptibility of infection. [0012] A person’s immune system also can be impacted by the amount and quality of sleep that the person gets, and sleep quality can be impacted by humidity levels. Dry air can increase the risk of respiratory system irritation, leading to coughing and sneezing during sleep. Very humid air can also make it difficult for the person to fall asleep, which in turn can reduce the amount of time the person spends in deep sleep stages and ultimately may decrease the person’s overall sleep quality. [0013] New approaches are desirable that enhance habitable environments and other indoor spaces and provide one or more benefits to one or more people in such indoor spaces via the determination or establishment of a humidity set point or humidity set point range for such indoor spaces. Brief Summary [0014] The embodiments of the present invention are directed to inventive systems and methods for determining one or more humidity related settings for an indoor space. In some embodiments, the systems, devices and methods described herein can enhance human health and wellness as a result of the humidity related metrics created, controlled or used in the indoor space. In some configurations, the term humidity set point includes a target or recommended humidity setting or range for given individual(s), space(s) and/or time(s). In addition, the humidity set point target or range may be for a sensor or a particular device within a space or multiple spaces. In yet other configurations, a humidity set point may be partially based on the location (e.g., geographic, architectural, furnishings, ventilation, and/or other details of the surroundings like weather, among other details related to the location). As discussed further below, the humidity set point or target may be a recommended range based on user preferences, user characteristics, user health concerns, building or space requirements or limitations, and seasonal or weather impacts, among many other factors. [0015] It is contemplated that the humidity set point may be dynamic, for example, the humidity set point or humidity range for an indoor space may change based on one or more factors and/or adjusted pursuant to one or more of the methods described herein. It is also contemplated that the set point may be static, for example, once the set point or range has been determined pursuant to one or more of the methods described herein, the set point or range may be associated with a particular space, subspace, individual, device, etc. For example, different static humidity set points or ranges may be determined for particular subspaces (e.g., rooms, lounge areas, other areas, etc.) within a space. For example, a static humidity set point or range may be lower for particular subspaces, such as server rooms, bedrooms, rooms with delicate artworks or other furnishings, clean rooms, or storage rooms, and higher for other subspaces. As another example, different static humidity set points or ranges may be used for different people of different ages, having different preferences, having different health conditions or concerns, having different schedules, etc. Such set points may be set to be static in rooms only used or primarily by such people. In some approaches, the humidity set point may dynamically change within a static humidity set point range. For example, humidity set points for a particular indoor space may be set for a particular static humidity range and may be dynamically adjusted within the static humidity range based on a number of factors and/or based on set point determinations made according to the methods described herein, such as changes in occupancy of the indoor space, activity within the indoor space, etc. In another example, the systems described herein may dynamically determine the humidity set point for a space according to the methods described herein as particular individuals enter and leave a space or subspaces within a space. In other examples, the systems and methods described herein may dynamically determine the humidity set point for a space based on the features of indoor space, the design of the indoor space, uses of the indoor space, or one or more items within the indoor space. [0016] The systems and methods described herein may be employed to determine set points for one or more of different types of humidity measurements such as absolute, relative, and/or specific humidity. The systems and methods described herein may also be employed to determine set points for or using other metrics or variables, such as dew point, that may be used to quantify or otherwise control the amount of water vapor in the air. Additionally, other metrics or variables, such as dew point, that can be used to quantify the amount of the water vapor in the air may be employed, manipulated, or otherwise taken into account in the systems and methods described herein. In some approaches, the particular humidity measurement, metric, or variable employed in the systems and methods described herein may depend on the particular space or devices therein.

[0056] Generally speaking, in accordance with the present disclosure, systems and methods for enhancing determining or otherwise establishing a humidity set point for one or more indoor spaces. In some embodiments this may include a system and/or method for determining a humidity set point for at least one controllable device in or that impacts humidity in the indoor space, such as a humidifier, dehumidifier, heating system, cooling system, fan, etc. One or more users may be use or otherwise be associated with or located in the indoor space. The systems and methods may be used to help improve the user(s)’ thermal comfort or sleep, reduce the negative impacts of low or high humidity on the user(s), reduce the spread and transmission of viruses in the indoor space, reduce mold in the indoor space, reduce damage to an indoor space or to items in an indoor space caused by excessive amount of moisture in the air, reduce damage to a person’s human or bodily defense system resulting from dry air in an indoor space, etc., or meet some other goal or objective associated with the user(s) or the indoor space. [0057] Now referring to FIG.1, FIG.1 shows a first embodiment of a method 100 in accordance with the present invention is provided for purposes of example, but not limitation. The method 100 is directed to determining a humidity set point for at least one indoor space. A humidity set point for an indoor space is the desired humidity a person or device seeks to maintain in the indoor space. A humidity set point range for an indoor space is the desired humidity range that the person or devices seeks to maintain the humidity within for the indoor space, and preferably the humidity within the indoor space stays within such designated humidity range. While the method 100 and other methods described herein reference relative humidity, other types of humidity measurements and metrics also may be used or taken into consideration. Thus, the method 100 and the other methods described herein may be employed to determine set points for one or more of different types of humidity measurements such as absolute, relative, and/or specific humidity. Further, it is contemplated that the method 100 and other methods described herein may be employed to determine set points for or using other metrics or variables, such as dew point, that may be used to quantify or otherwise control the amount of water vapor in the air. [0058] In some embodiments, the method 100 or portions thereof may be implemented by one or more devices or systems, such as a computer, smart phone, tablet, home automation system or device, HVAC system, air handling system, heating and/or cooling device or system, humidifier, dehumidifier or other humidity control system, other smart device, etc., or an application or other software operating on such one or more devices or systems. [0059] In step 102, a determination is made as to whether there is a relative humidity or relative humidity range preference for the indoor space. For example, a user may want the relative humidity within the indoor space to stay near a certain relative humidity level, below or above a certain relative humidity level, within a designated relative humidity level range, etc. More specifically, the user may want the relative humidity level within the indoor space to be at or near forty percent with a preferred range of plus/minus five percent, eight percent, ten percent, twelve percent, fifteen percent, etc. Alternatively, the user may want the relative humidity level with the indoor space to be or near twenty-five percent, thirty percent, thirty-five percent, forty- five percent, fifty percent, fifty-five, sixty percent, sixty-five, seventy percent, etc. A relative humidity preference and/or a relative humidity range preference may vary depending on the user, a characteristic (e.g., age, weight, body mass index, gender, race, ethnicity, clothing being worn, health condition) of the user, the time of day, the day of year, the design, furnishing or location of the indoor space, the current exterior climate, an activity the user is conducting or plans to conduct in the indoor space, a health condition associated with the user and/or another current or expected occupant of the indoor space, a goal or need of the user, etc. [0060] In some embodiments, during step 102, a user may input or provide an indication of a relative humidity level preference and/or a desired relative humidity range directly or indirectly to or via a device (e.g., smart phone, computer, tablet, hub device, etc.) or an application or other software operating on such device. For example, in some embodiments, the user may enter or otherwise provide the indication via a device or via an application or other software operating on a computer, a mobile device (e.g., smart phone, tablet), other smart device, visual display or input device, a website, etc. As another example, in some embodiments, the user may provide such information audibly via such application or software, via an Amazon Alexa device, computer, or other smart device. [0061] In some embodiments, prior to or during step 102 an application or other software may send or otherwise provide a message, instruction or other signal directly or indirectly to the user device or user to ask the user if the user has a relative humidity level preference and/or the desired relative humidity range. For example, in some embodiments, a device or an application or other software operating on a computer, a mobile device (e.g., smart phone, tablet), visual display or input device, other device, a website, etc., may send, display or otherwise provide a message, instruction or other signal to the user requesting such information. As another example, in some embodiments, the user may be queried for this information audibly via such application or software, via an Amazon Alexa device, computer, or other smart device. In one example, an application or other software may send or otherwise provide a message, instruction, question, query, request, survey or other signal directly or indirectly to the user device or user to provide a relative humidity level preference and/or range as part of creating a user account or profile. [0062] In some embodiments, during step 102 a user identifier may be received to identify a user that may be or is scheduled to be present, currently or at some future time, in the indoor space. The user identifier may be associated with a relative humidity level preference and/or range, for example, as part of a user account or profile. For example, a user may enter a user identifier via an input device. In another example, a user identifier may be automatically read from some piece of media, for instance smartcard or keycard. The user identifier may, for example, be encoded in a magnetic stripe, machine-readable symbol, or wireless transponder (e.g., RFID transponder) of the smartcard or keycard. In a further example, a user identifier may a associated with a user’s mobile or wearable device and may be automatically received when a user’s mobile or wearable device is recognized via a wireless network (e.g., a Wi-Fi network). In this manner, a determination is made as to whether there is a relative humidity or relative humidity range preference for the indoor space based on preferences associated with a user identifier. [0063] If the determination made during or the answer resulting from step 102 is “yes” the method 100 moves to step 104 during which the relative humidity preference and/or the relative humidity range preference is determined. [0064] In some embodiments, during step 104, a user may input or provide the relative humidity level preference and/or the desired relative humidity range directly or indirectly to or via a device (e.g., smart phone or other mobile device, wearable device, computer, tablet, hub device, server, database storing device, other smart device, etc.) or an application or other software operating on such device. [0065] In some embodiments, during step 104 a device or an application or other software may send or otherwise provide a message, instruction, question, survey or other signal directly or indirectly to the user device or user to instruct or nudge the user to provide the relative humidity level preference and/or the desired relative humidity range and how to provide such information. For example, in some embodiments, a device or an application or other software operating on a computer, a mobile device (e.g., smart phone, tablet), visual display or input device, other device, a website, etc., may send, display or otherwise provide a message, instruction or other signal to the user requesting such information or nudging the user to provide the information. As another example, in some embodiments, the user may be queried for this information audibly via such application or software, via an Amazon Alexa device, computer, mobile phone or tablet, or other smart device. [0066] In some embodiments, the message, instruction, question, query, request, survey or other signal sent by a device, application or other software for purposes of step 104 may be combined with the message, instruction or other signal sent by the device, application or other software as part of step 102. Similarly, a message, input, instruction or other signal received as part of the inquiry in step 102 also may include information related to a specific and preferred relative humidity level and/or humidity level range. For example, in some embodiments, a user might input or otherwise provide information regarding the users preferred relative humidity level and/or humidity level range via a device or an application or other software operating on such device, send a text, email or other message that includes such information, etc. [0067] As another example, in some embodiments, a device, application or other software may send or otherwise provide a message, instruction or other signal directly or indirectly to a database, computer, server, mobile device, or other device, smart sensor, environmental condition measuring device, etc., that may store or have access to relative humidity set point and/or relative humidity level range preference information associated with one or more users or one or more indoor spaces. For example, in some embodiments, a database or other application or device may store such information and regularly update such information based on information provided by a user, or otherwise indicated by the user based on previous activity involving the user setting a humidity set point level or a humidity level range. This information can then be shared or accessed during the methods described herein. [0068] If the determination made during or the answer resulting from step 102 is “no” the method 100 moves to step 106 during which a determination is made as to whether a user associated with the indoor space has one or more health concerns. In some embodiments, step 106 may be done prior to or as part of step 102. A health concern may be or include one or more of the following: asthma, rhinitis, an allergy, thermal discomfort or hypothermia, lethargy, sleep disruption, coughing, breathing difficulty, dehydration, dermatitis, eczema, virus, bacterial or other pathogen infection, respiratory infection, skin irritation, eye irritation, nose irritation, throat irritation, immune system compromising or deficiencies, fatigue, muscle cramps, heat exhaustion, etc., or other health related condition or other concern that may be impacted by humidity. [0069] In some embodiments, during step 106, a user may input or provide an indication of a health concern directly or indirectly to or via a device (e.g., smart phone or other mobile device, computer, tablet, hub device, tablet, wearable device, other smart device, etc.) or an application or other software operating on such device. [0070] In some embodiments, prior to or during step 106 a device or an application or other software operating on a device may send or otherwise provide a message, instruction, survey, request, query, question or other signal directly or indirectly to the user device or user to ask the user if the user has a health concern, and, if so, what such health concern might be or include. For example, a computer, or software operating on the computer, that is implementing some or all of the methods, or parts thereof, disclosed herein may generate and send a message or other signal to the user via the user’s email account, text message account, phone number, etc. requesting that the user provide information regarding whether or not the user has a health concern, what the health concern is, the amount of time the user has had the health concern, the symptoms of the health concern, medical and other treatment undergone by the user for the health concern, etc. In one example, an application or other software may send or otherwise provide a message, instruction, question, query, request, survey or other signal directly or indirectly to the user device or user to provide the health concern information as part of creating a user account or profile. [0071] In some embodiments, the message, instruction or other signal sent by a device, application or other software for purposes of step 106 may be combined with the message, instruction, survey, query, question, or other signal sent by the device, application or other software as part of step 102. Similarly, a message, input, instruction or other signal received as part of the inquiry in step 102 also may include information related to a health concern associated with a user. For example, a computer, or software operating on the computer, that is implementing some or all of the methods, or parts thereof, disclosed herein may receive an email message, text message, or other signal regarding a user’s has a health concern, what the health concern is, the amount of time the user has had the health concern, the symptoms of the health concern, medical and other treatment undergone by the user for the health concern, the symptoms of the health concern, etc. [0072] In some embodiments, during step 106 a user identifier may be received to identify a user that may be present, currently or at some future time, in the indoor space. The user identifier may be associated with information on one or more health concerns associated with the user, for example, as part of a user account or profile. For example, a user may enter a user identifier via an input device. In another example, a user identifier may be automatically read from some piece of media, for instance smartcard or keycard. The user identifier may, for example, be encoded in a magnetic stripe, machine-readable symbol, or wireless transponder (e.g., RFID transponder) of the smartcard or keycard. In a further example, a user identifier may be associated with a user’s mobile or wearable device and may be automatically received when a user’s mobile or wearable device is recognized via a wireless network (e.g., a Wi-Fi network). In this manner, a determination is made as to whether there a health concern associated with the user based on health concerns associated with a user identifier. [0073] In another embodiment, during step 106, the determination is made as to whether a user associated with the indoor space has one or more health concerns based on data received from one or more biometric devices. For example, the determination as to whether a health concern is associated with the user may be made based one or more biometric parameters measured by a biometric device associated with a user. The biometric device may be, for example, a wearable device. [0074] As another example, in some embodiments, a device, application or other software may send or otherwise provide a message, instruction or other signal directly or indirectly to a database, device, server, computer or other smart device, mobile device, wearable device, display device, sensor, etc., that may store or have access to health concern or other health related information associated with one or more users or one or more indoor spaces. For example, such information may include information regarding what the health concern is, the amount of time a user has had the health concern, medical and other treatment undergone for the user for the health concern, the symptoms of the health concern, etc. If the determination made during or the answer resulting from step 106 is “yes” the method 100 moves to step 108 during which the health concern is determined. [0075] In some embodiments, during step 108, a user may input or provide the health concern information directly or indirectly to or via a device (e.g., smart phone or other mobile device, computer, tablet, hub device, server, other smart device, wearable device, etc.) or an application or other software operating on such device. [0076] In some embodiments, during step 108 an application or other software may send or otherwise provide a message, instruction, question, query, request, survey or other signal directly or indirectly to the user device or user to instruct or nudge the user to provide the health concern information and how to provide such information. Similarly, in some embodiments, a device may send or otherwise provide a message, instruction or other signal directly or indirectly to the user device or user to instruct or nudge the user to provide the health concern information and how to provide such information. For example, a computer, or software operating on the computer, that is implementing some or all of the methods, or parts thereof, disclosed herein may generate and send a message or other signal to the user via the user’s email account, text message account, phone number, etc. suggesting or otherwise encouraging that the user provide information regarding whether or not the user has a health concern, what the health concern is, the amount of time the user has had the health concern, the symptoms of the health concern, the types of treatments, the user has undertaken for the health concern, etc. [0077] In some embodiments, the message, instruction or other signal sent by a device, application or other software for purposes of step 106 may be combined with the message, instruction or other signal sent by the device, application or other software as part of steps 102 and/or 106. Similarly, a message, input, instruction or other signal received as part of the inquiry in step 102 also may include information related to a specific and health concern associated with a user. For example, a computer, or software operating on the computer, that is implementing some or all of the methods, or parts thereof, disclosed herein may receive a text message, email message, message or other signal a user’s potential health concern, what the health concern is, the amount of time the user has had the health concern, the symptoms of the health concern, etc. [0078] As another example, in some embodiments, a device, application or other software may send or otherwise provide a message, instruction or other signal directly or indirectly to a database, device, user, sensor, display device, health records storage system, server, other smart device, wearable device, etc., that may store or have access to health concern or other information associated with one or more users or one or more indoor spaces. [0079] If the determination made during or the answer resulting from step 106 is “no” the method 100 moves to step 110 during which a determination is made as to whether a user associated with the indoor space is associated with a sensitive group. In some embodiments, step 110 may be done prior to or as part of step 106 and/or 102. In some embodiments, even if the answer resulting from step 106 is “yes”, the method 100 may move to step 110 instead of step 108. [0080] In some embodiments, a sensitive group may be or include one or more of the following: people above a designated age (e.g., fifty-five years of age, sixty-five years of age), people below five, ten, twenty or other designated number of years of age, toddlers and infants, elderly people, people with obesity, people with type two diabetes, people with a high body mass index (e.g., BMI of thirty or higher), people with sickle cell disease, asthma, allergies, a heart condition, lung conditions, kidney disease or other underlying medical or health condition or concern, people with low socio-economic status, etc. [0081] In some embodiments, during step 110, a user may input or provide an indication of being in a sensitive group directly or indirectly to or via a device (e.g., smart phone or other mobile device, computer, tablet, hub device, mobile device, wearable device, other smart device, etc.) or an application or other software operating on such device. [0082] In some embodiments, prior to or during step 110 an application or other software may send or otherwise provide a message, instruction or other signal directly or indirectly to the user device or user to ask the user if the user is a member of a sensitive group. Similarly, in some embodiments, a device may send or otherwise provide a message, instruction or other signal directly or indirectly to the user device or user to ask the user if the user is a member of a sensitive group, what the sensitive group is, how long the user has been a member of the sensitive group, etc. In one example, an application or other software may send or otherwise provide a message, instruction, question, query, request, survey or other signal directly or indirectly to the user device or user to ask the user if the user is a member of a sensitive group as part of creating a user account or profile. [0083] In some embodiments, the message, instruction or other signal sent by a device, application or other software for purposes of step 110 may be combined with the message, instruction or other signal sent by the device, application or other software as part of steps 102 and/or 106. Similarly, a message, input, instruction or other signal received as part of the inquiry in steps 102 and/or 106 also may include information related to a health concern associated with a user, as previously described above. [0084] As another example, in some embodiments, a device, application or other software may send or otherwise provide a message, instruction or other signal directly or indirectly to a database, device, server, computer, wearable device, other smart device, health records storage system, etc., that may store or have access to sensitive group information associated with one or more users or one or more indoor spaces, such as the type of sensitivity, the length of time one or more users has been a member of the sensitive group, the symptoms experienced by one or more members of the sensitive group, etc. [0085] In some embodiments, during step 110 a user identifier may be received to identify a user that may be present, currently or at some future time, in the indoor space. The user identifier may associate the user with one or more sensitive groups, for example, as part of a user account or profile. For example, a user may enter a user identifier via an input device. In another example, a user identifier may be automatically read from some piece of media, for instance smartcard or keycard. The user identifier may, for example, be encoded in a magnetic stripe, machine- readable symbol, or wireless transponder (e.g., RFID transponder) of the smartcard or keycard. In a further example, a user identifier may be associated with a user’s mobile or wearable device and may be automatically received when a user’s mobile or wearable device is recognized via a wireless network (e.g., a Wi-Fi network). In this manner, a determination is made as to whether the user is the member of a sensitive group based on information associated with a user identifier. [0086] If the determination made during or the answer resulting from step 110 is “yes” the method 100 moves to step 112 during which the sensitive group information is determined. [0087] In some embodiments, during step 112, a user may input or provide the sensitive group information directly or indirectly to or via a device (e.g., smart phone, computer, tablet, hub device, mobile device, wearable device, other smart device, etc.) or an application or other software operating on such device. [0088] In some embodiments, during step 108 an application or other software may send or otherwise provide a message, instruction, question, survey, query, request or other signal directly or indirectly to the user device or user to instruct or nudge the user to provide the sensitive group information and how to provide such information. Similarly, in some embodiments, a device may send or otherwise provide a message, instruction, survey, question, query, request or other signal directly or indirectly to the user device or user to instruct or nudge the user to provide the sensitive group information and how to provide such information. In some embodiments, the message, instruction or other signal sent by a device, application or other software for purposes of step 112 may be combined with the message, instruction or other signal sent by the device, application or other software as part of steps 102 and/or 106. Similarly, a message, input, instruction or other signal received as part of the inquiry in steps 102 and/or 106 also may include information related to a sensitive group associated with a user. [0089] As another example, in some embodiments, a device, application or other software may send or otherwise provide a message, instruction or other signal directly or indirectly to a database, device, health records storage system, computer, etc., that may store or have access to sensitive group information associated with one or more users or one or more indoor spaces. [0090] In some embodiments, steps 108 and 112 may be combined into a single step, and both may occur after step 106 or after step 110 if the answer to either of or both of questions in steps 106 and 110 is “yes”. In some embodiments, after step 108 the method may move to step 110 instead of moving directly to step 118. [0091] In some approaches, the method 100 may optionally include creating a user profile or account associated with a user of an indoor space. In the user profile or account, a user may specify information related to a specific or preferred relative humidity level and/or relative humidity level range for one or more spaces, one or more health concerns, and information regarding whether the user is a member of a sensitive group. Further, in the user profile or account, a user may specify information related to other characteristics associated with the user. The user may also link one or more devices, such as a biometric or personal mobile device, to the user’s profile or account. The user profile or account may be stored, for example, along with a user identifier in a user database. Now referring back to step 104, after the relative humidity preference and/or relative humidity preference range is determined during step 104, the method 100 moves to step 114 during which a determination is made regarding whether such relative humidity preference and/or relative humidity preference range are within an allowed range or at a specific value. For example, in some embodiments, a heating, cooling, dehumidifying, humidifying, HVAC device or other device or system that controls or otherwise impacts the relative humidity level within an indoor space may not be able to establish or maintain a relative humidity level in the indoor space at the desired relative humidity set point and/or within the desired relative humidity range. This may be a temporary issue impacted by local climate, weather or environmental condition, activities occurring in the indoor space (e.g., cooking, clothes or dishwashing, steam cleaning, etc.) or other factor, or may be a broader problem depending on the capabilities of devices or systems, the preferences, etc. [0092] As examples of when a preferred relative humidity level and/or a preferred relative level humidity range determined during step 104 may not fall within an allowed range or at a specifically allowed value for an indoor space, a zero percent humidity level may not fall within an allowed range or be used as a humidity set point, as it may be impossible or too energy draining for the device(s) or system controlling or maintaining the humidity level in the indoor space. In some cases, even a low humidity set point level of three percent, five percent, ten percent, etc., may be outside the capabilities of such device(s) or system for establishing or maintaining the humidity level within the indoor space. [0093] If the determination made during or the answer resulting from step 114 is “no” in some embodiments the method 100 moves to optional step 116 during which a notification, message or other signal is sent directly or indirectly to a user or user device to notify the user that the preferred relative humidity and/or the preferred relative humidity range does not fall within an allowed range or at specifically allowed value. As a further option, in some embodiments, the method 100 also may return to step 102 or step 104 after step 114 (thereby skipping optional step 116) or after step 116. Alternatively, the method 100 may disregard one or both of the relative humidity preference and the relative humidity preference range determined during step 104, request a confirmation of the relative humidity preference and the relative humidity preference range determined during step 104, move directly to step 118, etc. [0094] If the determination made during or the answer resulting from step 114 is “yes”, after steps 108 and 12, after optional step 116, or in some embodiments directly from step 114 even if the answer resulting from step 114 is “no”, the method 100 moves to step 118 during which a relative humidity set point is determined based on information determined in one or more of the prior steps, as will be shown in examples below. [0095] In some embodiments, if the determination made during or the answer resulting from step 110 is “no”, the method 100 may move to optional step 120 during which a relative humidity range for an indoor space is determined. In some embodiments, step 120 may be part of step 118. In some embodiments, if the determination made during or the answer resulting from step 106 is “yes”, then after step 108, the method 100 may move to step 120 prior to step 118 or after step 118. Similarly, if the determination made during or the answer resulting from step 110 is “yes”, then after step 110, the method 100 may move to step 120 prior to step 118 or after step 118. [0096] Relative humidity ranges for an indoor space may be set at various amounts of, for example, five percent, eight percent, ten percent, fifteen percent, twenty percent, twenty-five percent, etc. Different relative humidity ranges may be preferred or used for different situations, for different activities within an indoor space, for different indoor spaces, different health concerns, different occupants or users of an indoor space, different times, etc. For example, people with chronic health concerns, such as asthma, may set the relative humidity range narrower than the general population. Also, the relative humidity range for an unoccupied space may be much wider than an occupied space. [0097] As a further example, in some embodiments, when a user has no preference for a humidity set point or humidity set point range, and the user has no specific health concern, the relative humidity set point may be set at forty-five percent and the relative humidity set point range may be set at ten percent, and these settings may be used as default values. As another example, in this situation, the relative humidity set point for the indoor space may be set at forty percent, forty-two percent, forty-six percent, etc. and the relative humidity set point range for the indoor space may be set at five percent, eight percent, twelve percent, fifteen percent, twenty percent, etc. [0098] In some embodiments, the method 100 of determining a humidity set point for an indoor space may also account for more than one user of the indoor space, or otherwise take into account the preferences, needs, health status, schedules, etc., of two or more users of an indoor space. For example, the method 100 may determine humidity preferences, health concerns, and sensitive groups for more than one user of the indoor space. To account for more than one user, the method 100 may execute one or more of steps 102 to 120 for each user (i.e., for each of a first user, a second user, etc.). [0099] In some instances, there may be conflicting humidity preferences or needs among users of the indoor space. By some approaches, when there are conflicting humidity preferences among users of the indoor space, preference may be given to a user who is member of a sensitive group over a user who is not. For example, when a preferred humidity level determined at step 104 for a first user is forty-five percent but a preferred humidity level determined at step 104 for a second user is fifty percent and the second user is elderly, preference is given to the second user because, as an elderly person, the second user is a member of a sensitive group. [00100] In other approaches, when there are conflicting humidity preferences among users of the indoors space, preference may be given to the user who has a health concern over a user who does not have a health concern. Further, preference may be given to a user who has more than one health related condition or concern over another user who only has one or less. The method may also further include sending a notification to one or more users of the indoor space, for example, regarding the conflicting preferences or the ultimate set point determination made based on the preferences among users. [00101] By some approaches, when there are conflicting humidity preferences among users of the indoors space, preference may be given to a narrow preference range within a broader preference range or to the overlap between two different preference ranges if such overlap exists, etc. For example, when a preferred humidity range determined at step 104 for a first user is forty to fifty percent and a preferred humidity range determined at step 104 for a second user is forty-five to fifty-five percent, preference may be given to the overlap between the two ranges (i.e., forty-five to fifty percent). In another example, when a preferred humidity range determined at step 104 for a first user is forty to fifty percent and a preferred humidity range determined at step 104 for a second user is forty-five to fifty percent, preference may be given to the narrower range preferred by the second user (i.e., preference may be given to the forty-five to fifty percent range). [00102] Example 1. The user has a preference on humidity, and so the answer at step 102 is “yes”. During step 104, the user provides a relative humidity preference of forty percent and a relative humidity preference range of ten percent for an indoor space. Assuming that both of them are within allowed ranges for an indoor space, during step 118 the relative humidity for the indoor space is set at forty percent (and is the humidity set point for the indoor space). As part of step 118, or alternatively as part of step 120, the relative humidity range for the indoor space is set at ten percent to create a range of thirty percent to fifty percent for the indoor space. [00103] Example 2. The user has a preference on humidity, and so the answer at step 102 is “yes”. During step 104, the user provides a relative humidity preference of seventy percent and a relative humidity preference range of ten percent for an indoor space. During step 118 it is determined that the relative humidity preference of seventy percent is outside an allowed level for the indoor space (e.g., a minimum of thirty percent and a maximum of sixty percent). As one potential result, during step 118 the relative humidity level for the indoor space is set at sixty percent (and is the humidity set point for the indoor space), thereby overriding the user preference. As part of step 118, or alternatively as part of step 120, the relative humidity level range is set at zero percent, thereby also overriding the user preferences. As another potential result, during step 118 the relative humidity level for the indoor space is set at seventy percent (and is the humidity set point for the indoor space even though the humidity level in the indoor space may never reach that level). As part of step 118, or alternatively as part of step 120, the relative humidity level range is set at sixty to eighty percent. As another potential result, during step 118 the relative humidity level for the indoor space is set at sixty-five percent (and is the humidity set point for the indoor space). As part of step 118, or alternatively as part of step 120, the relative humidity level range is set at sixty to seventy percent for the indoor space. [00104] Example 3. The user does not have a preference on relative humidity level or on relative humidity range within an indoor space, and so the answer at step 102 is “no”. The user also does not have a health concern, so the answer at step 106 is no, and is not a part of a sensitive group, so the answer at step 110 is “no”. During step 118, the relative humidity level for the indoor space is set at forty-five percent (and is the humidity set point for the indoor space). As part of step 118, or alternatively as part of step 120, the relative humidity level range is set at thirty-five to fifty-five percent for the indoor space. [00105] Example 4. The user does not have a preference on relative humidity level or on relative humidity range within an indoor space, and so the answer at step 102 is “no”. However, the user does have asthma symptoms, so the answer at step 106 is ‘yes”. During step 118, the relative humidity level for the indoor space is set at forty-five percent (and is the humidity set point for the indoor space). As part of step 118, or alternatively as part of step 120, the relative humidity level range is set at forty to fifty percent for the indoor space. [00106] Example 5. The user does not have a preference on relative humidity level or on relative humidity range within an indoor space, and so the answer at step 102 is “no”. Also, the user does not have a health concern, so the answer at step 106 is “no”. However, the user is a member of a sensitive group (e.g., the person is sixty-eight years old and is obese), so the answer at step 110 is “yes”. During step 118, the relative humidity level for the indoor space is set at forty-five percent (and is the humidity set point for the indoor space). As part of step 118, or alternatively as part of step 120, the relative humidity level range is set at forty to fifty percent for the indoor space. [00107] Example 6. The user is aware of his or her condition of dry mouth when the humidity level is below fifty percent, so the user has a preference that the humidity level is set to be above fifty percent. Accordingly, the answer at step 102 in FIG.1 is “yes”. The user can use a user interface, such as an application or other software operating on such one or more devices or systems to select the preference that the humidity level be set to above fifty percent. Since above fifty percent can be set within the determined set point range, but can also be beyond the recommended range, a notification 116 will be sent to the user and the system will determine a range that meets both the user’s preference and the optimal set point range for health concerns. [00108] In some situations, a user may have a health concern (e.g., the user has asthma) and the user may be a member of a sensitive group (e.g., the user is a toddler, the user has a kidney condition, the user is older than sixty-five years of age). Thus, in this situation, the answer to both questions at steps 106 and 110 may be “yes”. During step 118, the relative humidity level for the indoor space may be set at forty-five percent (and is the humidity set point for the indoor space). As part of step 118, or alternatively as part of step 120, the relative humidity level range may be set at forty to fifty percent for the indoor space. [00109] Now referring to FIG.2, FIG.2 shows a first embodiment of a method 200 in accordance with the present invention is provided for purposes of example, but not limitation. The method 200 is directed to determining a humidity set point for at least one indoor space where a user might have a preference during a first time period, such as the day time or during a time when the user is away from the indoor space, and/or another preference during a second time period, such as the evening or night time. For purposes of discussion of method 200, references to daytime, away and night modes and settings will be used, but they can be exchanged for other time periods (e.g., 10:00 am to 2:00 pm, 2:30 pm to 5:00 pm, 9:00 am to 10:15 am, 8:30 pm to 1:30 am, 6:00 pm to 6:00 am, 10:00 am to 10:00 pm). While the method 200 references relative humidity, other types of humidity measurements and metrics also may be used or taken into consideration. Thus, the method 200 may be employed to determine set points for one or more of different types of humidity measurements such as absolute, relative, and/or specific humidity. Further, it is contemplated that the method 200 may be employed to determine set points for or using other metrics or variables, such as dew point, that may be used to quantify or otherwise control the amount of water vapor in the air. [00110] In some embodiments, the method 200 may be implemented by one or more devices or systems, such as a computer, smart phone, tablet, home automation system, HVAC system, heating and/or cooling device, humidity controlling device, other smart device, etc., or an application or other software operating on such one or more devices or systems. [00111] In step 202, a determination is made as to whether there is a preferred relative humidity level preference and/or a relative humidity level range for a first time period for the indoor space. For example, during a daytime a person may have a humidity set point preference of fifty percent, and during the hours of 10:00 pm to 6:00 am, or during another time period for sleeping, the relative humidity set point preference may be fifty-five percent. Similarly, the person may have a humidity set point range preference during the daytime of forty-five to fifty- five percent and during the hours of 10:00 pm to 6:00 am or another time period for sleeping, the relative humidity set point range preference may be fifty to sixty percent. In some embodiments, during step 202, a user may input or provide an indication of a relative humidity level preference and/or a desired relative humidity range during a first time period for the indoor space directly or indirectly to or via a device (e.g., smart phone or other mobile device, computer, tablet, hub device, wearable device, etc.) or an application or other software operating on such device. [00112] In some embodiments, prior to or during step 202 an application or other software may send or otherwise provide a message, instruction, survey, question, request or other signal directly or indirectly to the user device or user to ask the user if the user has a relative humidity level preference and/or the desired relative humidity range during a first time period. Similarly, in some embodiments, a device may send or otherwise provide a message, instruction, survey, question, request or other signal directly or indirectly to the user device or user to ask the user if the user has a relative humidity level preference and/or the desired relative humidity range to the first time period. [00113] If the determination made during or the answer resulting from step 202 is “yes” the method 200 moves to step 204 during which the relative humidity preference and/or the relative humidity range preference is determined for the first time period. For example, there may be daytime humidity set point preference of fifty percent and a daytime humidity set point range preference of forty-five to fifty-five percent. Alternatively, there may be a night-time or sleeping time period humidity set point preference of fifty-five percent and a humidity set point range preference of fifty to sixty percent. [00114] If the determination made during or the answer resulting from step 202 is “no”, or after step 204, the method 200 moves to optional step 206 during which a determination is made as to whether there is a relative humidity level preference and/or a relative humidity level range preference for a second time period for the indoor space. For example, during a time period when occupants may not be within an indoor space, the humidity level preference may be set at fifty percent and the humidity level range preference may be set at twenty-five to seventy-five percent. In some situations, the preferences may be in part based on energy use considerations, a desire to prevent mold issues, reduce the impact of dry or moist air conditions on the indoor space and furniture and other objects within the indoor space, etc. Step 206 may be conducted in a manner similar to step 202 described above. [00115] The second time period determined during step 206 typically will be different than the first time period and will not overlap with the first time period. For example, a first time period could be a time period the occupants are away from an indoor space and a second time period could be a time period while one or more occupants are in the indoor space. As another example, a first time period could be while an occupant is awake and in an indoor space and a second time period could be while the occupant is sleeping in the indoor space. As one further example, a first time period could be while one or more occupants are in an indoor space and a second time period could be while a different group of one or more occupants (which may or may not include one or more of the occupants during the first time period) are in the indoor space, as the different occupants may have different humidity level set point preferences, different humidity level range preferences, different health concerns, etc. [00116] If the determination made during or the answer resulting from step 206 is “no” the method 200 moves to step 118 (which may include step 120) and/or 120 during which a relative humidity preference and/or a relative humidity range preference is determined for the indoor space as previously discussed above. [00117] The following are further examples related to method 200. [00118] Example 7. A user has a relative humidity level preference and/or a relative humidity level range preference and/or a relative humidity level range preference for an indoor space at night (e.g., a first time period), so the answer at step 202 is “yes”. During step 204, it is determined that the relative humidity level during the night or first time period will be forty-five percent (which is the humidity set point for the first time period) and/or that the relative humidity level range during the night or first time period will be thirty-five to fifty-five percent. [00119] The user also has a relative humidity level preference and/or a relative humidity level range preference for the indoor space while the user is away from the indoor space, such as while the user is at work, shopping, or otherwise not in the indoor space or during a second time period, and so the answer at step 206 is “yes”. During step 208, it is determined that the relative humidity level during the away or second time period will be fifty percent (which is the humidity set point for the second time period) and/or that the relative humidity level range during the away or second time period will be twenty-five to seventy-five percent. [00120] During step 118, the relative humidity level for the indoor space is set at forty percent for times outside the first time period and the second time period (and is the humidity set point for the indoor space during those times). As part of step 118, or alternatively as part of step 120, the relative humidity level range is set at thirty to fifty percent for the indoor space for times outside the first time period and the second time period. [00121] Example 8. A user has no preference on relative humidity level or relative humidity level range for an indoor space, but the user and the user’s children have asthma symptoms. The user also wants to have some specific humidity settings when the user is away from the indoor space and when the user is sleeping. This example highlights a combined use of methods 100 and 200. [00122] In this example, the answer at step 202 is “yes”. During step 204, it is determined that the relative humidity level during the night or first time period will be fifty percent (which is the humidity set point for the first time period) and/or that the relative humidity level range during the night or first time period will be forty-five to fifty-five percent. [00123] In this example, the answer at step 206 is “yes”. During step 208, it is determined that the relative humidity level during the away or second time period will be fifty percent (which is the humidity set point for the second time period) and/or that the relative humidity level range during the away or second time period will be twenty-five to seventy-five percent. [00124] In this example, the answer at step 106 is “yes” and it is determined during step 108 that the user has asthma. This information is then used in step 118. Alternatively, in this example, the answer at step 106 might be “no”, but the answer at step 110 might be “use”. It is then determined during step 112 that the user should be considered as part of a group that has asthma or asthma like symptoms. [00125] During step 118, based at least in part on the information determined during steps 108 or 110, the relative humidity level for the indoor space is set at forty-five percent for times outside the first time period and the second time period (and is the humidity set point for the indoor space during those times). As part of step 118, or alternatively as part of step 120, the relative humidity level range is set at forty to fifty percent for the indoor space for times outside the first time period and the second time period. [00126] Example 9. In some situations, application of the methods and systems described herein may be further complicated due to several factors, such as a result of the uncertainty of the occupancy of an indoor space and the time of the day that the indoor space may be occupied by one or more people. For example, assume for this example that a homeowner is living with another person (the “roommate”) at a house and that both of them are healthy. They also have a preference on the humidity level at certain times of the day. Thus, the answer at step 102 is “yes” and the answers at steps 106 and 110 are each “no” for their day to day living. The two people also enable a night mode, as well as an away mode while they are at work. [00127] In this example, the homeowner’s parents will visit them one Saturday and will stay at the house for one night and then leave on Sunday. Both of the parents have asthma related concerns, so while the parents are visiting and staying at the house, the answers to questions 106 and/or 110 may be “yes”. [00128] Given this scenario, the humidity set points and the humidity set point ranges may be set as follows during different parts of the days.

[00129] In some embodiments, the methods 100 and 200, or portions thereof, also may include determining if a mold issue exists in an indoor space. For example, mold can enter an indoor space in a variety of ways, such as through open doors and windows, and via heating and air conditioning systems. Mold also might be brought into an indoor space via clothing, pets, hand-carried items such as purses and bags, etc. Mold can grow behind drywall used for an indoor space and ceiling mold can result from a lack of ventilation in the indoor space or high humidity in the indoor space. Mold also often can be found in bathrooms, kitchens and basements, near pipes or ducts, under a leaking roof, etc. Depending on the amount or moisture of humidity in an indoor space, the mold may further grow and spread. [00130] In some embodiments, the method 100 may include a step during which a determination is made as to whether there is a mold concern, or a mold issue associated with an indoor space. This determination may be made before or after one or more of steps 102, 104, 106, 108, 110, 112, 114 or 116. [00131] In some embodiments, a user may input or provide an indication of a mold issue or concern in the indoor space directly or indirectly to or via a device (e.g., smart phone or other mobile device, computer, tablet, hub device, wearable device, other smart device, etc.) or an application or other software operating on such device. For example, the user may enter information into an application operating on the user’s mobile phone or tablet to indicate that mold exists in an indoor space, the type of mold that is present in the indoor space, the current humidity level and/or temperature in the indoor space, etc. [00132] In some embodiments, a device, an application or other software may send or otherwise provide a message, instruction, survey, question or other signal directly or indirectly to the user device or the user to ask the user if the user if there is a mold concern or issue associated with the indoor space. For example, a computer, or software operating on the computer, implementing some or all of the methods, or parts thereof, disclosed herein may generate and send a message or other signal to the user via the user’s email account, text message account, phone number, etc. requesting that the user provide information regarding whether or not mold exists in an indoor space, the type and amount of mold that might exist in the indoor space, etc. [00133] If a determination is made that a mold concern or mold issues exists for the indoor space the method 100 may as part of step 118 set the relative humidity level for the indoor space to forty percent (which is the humidity set point for the indoor space). As part of step 118, or alternatively as part of step 120, the relative humidity level range is set at thirty to fifty percent for the indoor space. One or both of these settings may be changed further if a user has a health concern, is a member of a sensitive group, has a humidity level preference or a humidity value range preference, or wishes to implement a humidity level value or a humidity value range during one or more time periods or at certain times. [00134] In some embodiments, similar to the embodiment for method 100, the method 200 may include a step during which a determination is made as to whether there is a mold concern, or a mold issue associated with an indoor space. This determination may be made before or after one or more of steps 202, 204, 206 or 208. [00135] In some embodiments, the methods 100 and 200, or portions thereof, described with reference to FIGS.1 and 2 may determine humidity set points based, at least in part, on the features of indoor space, the design of the indoor space, uses of the indoor space, and/or one or more items within or otherwise associated with the indoor space. This may be in addition to considering the needs, characteristics, schedules, etc. of one or more particular users or occupants of the space. Certain indoor spaces may have different humidity set point preferences or requirements, for example, based on features of the indoor space (e.g., paint, wood panels or flooring, wallpaper, etc. that is located in the indoor space), the design of the indoor space, uses of the indoor space, or one or more items (e.g., artworks, photographs, books, plants, stamp collections, electronic devices, instruments or other furnishings that may be damaged or otherwise impacted by a humidity level that is too low, too high, or too varied during a day or other time period) within or otherwise associated with the indoor space. [00136] A user may input or provide an indication of the features of indoor space, the design of the indoor space, uses of the indoor space, or one or more items within the indoor space directly or indirectly to or via a device (e.g., smart phone or other mobile device, computer, tablet, hub device, wearable device, other smart device, etc.) or an application or other software operating on such device. For example, the user may enter information into an application operating on the user’s mobile phone or tablet to indicate one or more features of indoor space, the design of the indoor space, uses of the indoor space, or an inventory of items within the indoor space. [00137] In some embodiments, a device, an application or other software may send or otherwise provide a message, instruction, survey, question or other signal directly or indirectly to the user device or the user to ask the user to input information regarding features of the indoor space, design of the indoor space, uses of the indoor space, or items present within the indoor space associated with the indoor space. For example, a computer, or software operating on the computer, implementing some or all of the methods, or parts thereof, disclosed herein may generate and send a message or other signal to the user via the user’s email account, text message account, phone number, etc., requesting that the user provide information regarding whether or not certain features or items are present in an indoor space, the type of uses for the indoor space or activities expected in the indoor space, the design of the indoor space, etc. [00138] In yet other embodiments, one or more items within or associated with the indoor space may be automatically detected. Items, for example, may be detected via a machine- readable symbol (e.g., barcode or April tag) or wireless transponder (e.g., RFID transponder). In this manner, a determination may be made as to whether a particular item is present within an indoor space or a particular zone of an indoor space. That is a system may automatically take an inventory of items present within an indoor space or a particular zone of the indoor space. In one example, the space may be a warehouse or other storage area. When one or more items with RFID tags are placed within the warehouse, a system such as the system 300 described with reference to FIG.3 may automatically detect the one or more items via an RFID tag. In this manner, the system may automatically take an inventory of items in the warehouse. In some approaches, humidity preferences may be associated with particular items, for example, in a database. Accordingly, a humidity set point for the warehouse may be dynamically determined based on the inventory of items detected in or otherwise determined to be in the warehouse. [00139] In some approaches, the humidity set points for the indoor space may be dynamic set points that change, for example, based on an inventory of items within the space. Items that may prompt a dynamic change to humidity set points for an indoor space may include, for example, plants, fitness equipment, pieces of art, wines, cigars, items with adhesive materials, electrical equipment or devices, medical equipment or devices, devices or other items that generate static electricity, devices or other items that are susceptible to corrosion, etc. [00140] In other approaches, the humidity set points for the indoor space may be dynamic set points that change, for example, based on changes in features of the indoor space. For example, humidity set points for an indoor space may dynamically change when a new feature is installed within the space. Features that may prompt a dynamic change to humidity set points for an indoor space may include water features, electrical installations, storage features, ventilation features (e.g., windows, doors), particular building materials (e.g., wood, steel, paint, wood panels, wallpaper, masonry), etc. [00141] It is further contemplated that methods 100 and 200 described with reference to FIGS.1 and 2 may determine humidity set points for one or more particular zones, such as subspaces, rooms, or areas, within an indoor space. An indoor space may have different humidity set point preferences or requirements, for example, for different zones, such as a bedroom versus a plant room, art studio, or home office, within the indoor space. In some approaches, the methods 100 and 200 may be employed to dynamically adjust humidity set points for zones of the indoor space. Dynamic set point adjustments for zones may be made based on one or more of the aforementioned factors. [00142] Turning to FIG. 3, FIG.3 depicts an exemplary system 300 for determining a humidity set point for an indoor space or a portion thereof. In some approaches, the system 300 may be a standalone system for determining a humidity set point in an indoor space. In other approaches, the system 300 may form part of, or otherwise incorporate, one or more existing systems or device in the indoor space, such as HVAC or other air handling systems or devices. In some forms, the system 300 may form part of a home wellness and/or a “smart home” system in the indoor space. [00143] As shown in FIG.3, the system 300 may include one or more indoor sensors 310. The indoor sensors 310 may include one or more sensors configured to sense, detect, or otherwise measure one or more parameters of the air in the indoor space. The indoor sensors 310 may be configured to send signals to the system 300. The indoor sensors 310 may be in the form of standalone sensors or in the form of sensor arrays. The indoor sensors 310 may be, for example, temperature sensors, humidity sensors, air flow sensors, air quality sensors (e.g., CO ₂ sensors), or other suitable sensors. Parameters that may be sensed, detected, or otherwise measured by indoor sensors 310 include, but are not limited to, temperature, humidity, air flow, dry bulb temperature, wet bulb temperature, dew point, relative humidity, and enthalpy. [00144] The system 300 may also optionally include one or more outdoor sensors 320 to measure parameters of air in the outdoor space. The outdoor sensors 320 may include one or more sensors located outside of the indoor space and configured to send signals to the system 300, and may also include sensors associated with weather stations, which may broadcast air temperature and humidity data, air quality data, weather predictions or forecasts, or other information for public use. The system may also include one or more occupancy sensors 330, motion detectors, face or other visual recognition technologies, or other technology or devices located in the indoor space to sense, detect, or otherwise measure the occupancy of the indoor space or to identify the presence of a particular occupant in the indoor space. [00145] The system 300 may further include one or more air handling units 340. The air handling unit 340 may include one or more controllable devices configured to control one or more air parameters within the indoor space. In some embodiments, one or more controllable devices included in air handling unit 340 may be used to control the humidity in the indoor space or to implement the humidity set points for the indoor space, for example, as described with reference to FIGS.1 and 2. In some approaches, the air handling unit 340 may include one or more of the following controllable devices: a humidifier 341, a dehumidifier 342, a heating unit 343, a cooling unit 344, a fan and/or blower 347, and a window and/or vent 348. [00146] The humidifier 341 may be configured to increase the moisture (i.e., humidify) in air within the indoor space, for example, during dry periods. The humidifiers 341 may include a reservoir (not shown) that retains water to either be added to the air in a humidification mode or removed from the air in a dehumidification mode. The humidifiers 341 may also include a compressor or other cooling system (not shown) used to, for example cool air as part of removing moisture from the air. The humidifier 341 may also include a heating element to heat air as part of adding moisture to the air. [00147] The dehumidifier 342 may be configured to lower moisture (i.e., dehumidifies) in air within the indoor space, for example, during humid periods. The dehumidifiers 342 may include a reservoir (not shown) that retains water to either be added to the air in a humidification mode or removed from the air in a dehumidification mode. The dehumidifiers 342 may also include a compressor or other cooling system (not shown) used to, for example cool air as part of removing moisture from the air. The humidifier 342 may also include a heating element to heat air as part of adding moisture to the air. [00148] The heating unit 343 may heat air or provide heated air to the indoor space or to portions thereof. The heater unit 343 may take any of a large variety of forms. The heating unit 343 may be, for example, an electric heater, which employs a resistive radiant element to heat air. The heating unit 343 may also take the form of a forced air heater which may include burners that burn a fuel such as natural gas or propane. The heating unit 343 may alternatively take the form of oil furnaces, gas furnaces, or the like. In some embodiments, hot water supplied from a boiler or other hot water source also may be included. [00149] The cooling unit 344 may cool air or provide cooled air to the indoor space or to portions thereof. The cooling unit 344 may include one or more compressors or other cooling systems which may form part of an air conditioner cooling unit. The cooling unit 344 may be fluidly coupled to control pressure of a fluid, coupled with one or more coils or other heat exchangers, and may operate in a similar fashion to standard air conditioner units to remove heat from the air. In some embodiments, chilled water supplied from a cooling system or other chilled water source also may be included. [00150] The fans and/or blowers 347 may facilitate air circulation in the indoor space or portions thereof. In some embodiments, the fans and/or blowers 337 may be coupled to one or more ducts and/or vents to facilitate fresh air exchange in the indoor space. The fans and/or blowers 347 may circulate air within the air handling unit 340 and/or within the indoor space or portions thereof. The fans and/or blowers 347 may expel air to an outdoor environment and/or draw fresh air from the outdoor environment, prior to treating the fresh air. In particular, a high flow ventilation system may expel indoor air to an outdoor space. A heat exchanger may advantageously be employed to recover energy from the outgoing air. [00151] The windows and/or vents 348 may facilitate the flow from an outdoor space into the indoor space. The windows and/or vents 348 may be communicatively coupled to control circuit 350 such that the control circuit 350 may control the opening and closing of the windows and/or vents 348, for example, in response to detected humidity levels or in response to humidity set points. [00152] System 300 generally includes a control circuit 350. The control circuit 350 typically comprises one or more processors or microprocessors. The control circuit may be implemented as one or more processor devices as are well known in the art. Generally, the control circuit 350 of the system 300 may comprise fixed-purpose hard-wired platforms or can comprise a partially or wholly programmable platform. These architectural options are well known and understood in the art and require no further description here. The system and/or control circuit 300 can be configured (for example, by using corresponding programming as will be well understood by those skilled in the art) to carry out one or more of the steps, actions, and/or functions described herein. In some implementations, the control circuit 350 and the memory may be integrated together, such as in a microcontroller, application specification integrated circuit, field programmable gate array or other such device, or may be separate devices coupled together. [00153] The control circuit 350 may be configured to determine and/or control a humidity set point for the indoor space. The control circuit 350 may also be configured to determine and/or control a humidity set point for air handling system 340, or one or more devices included therein. In some embodiments, the control circuit 350 may determine one or more humidity set points for the indoor space, for example, according to the methods described with reference to FIGS.1 and 2. [00154] The system 300 may further include one or more databases 360. The databases, for example, may receive and/or store data acquired by sensors such as indoor sensors 310, outdoor sensors 320, and occupancy sensors 330. The databases 360 may also receive and/or store data acquired by input devices 370. [00155] In some embodiments, the databases 360 may include a space database 362 that receives and/or stores data related to an indoor space. The space database 362 may include, for example, data related to one or more of: a size of the indoor space; a location of the indoor space; an altitude of the indoor space, an external weather condition proximate to a geographic location of the indoor space; a current occupancy of the indoor space; a recent occupancy of the indoor space; an expected occupancy of the indoor space at a future time; a pattern of usage of the indoor space during at least one time period; a pattern of occupancy of the indoor space over at least one time period; a recent occupancy of the at least one indoor space by a particular individual; a frequency of occupancy of the indoor space by a particular individual; a pattern of occupancy of the indoor space by the individual over at least one time period; a schedule of use associated with the indoor space; a usage of the indoor space; an identification of at least one controllable device located in the indoor space; an identification of at least one controllable device associated with the indoor space; an identification of a controlling device associated with the indoor space; an identification of at least one feature of a controllable device located in the indoor space; an identification of at least one feature of a controllable device associated with the indoor space; and an identification of at least one feature of a controlling device associated with the at least one indoor space. [00156] In some embodiments, the databases 360 may also include a user database 364 that receives and/or stores data related to one or more individuals or groups of individuals associated with an indoor space. The user database 364 may include a user identifier associated with a particular individual or group of individuals (i.e., a user). The user database 364 may include data related to one or more of: a health concern associated with an individual or group of individuals; a characteristic of an individual or group of individuals; a humidity preference associated with an individual or group of individuals; an activity scheduled for an individual or group of individuals; and a sensitivity of an individual or group of individuals, for example, to a particular environmental parameter. The heath concern associated with an individual or group of individuals associated with the indoor space may include one or more of: asthma; rhinitis; an allergy; hypothermia; lethargy; eye irritation; nose irritation; coughing; breathing difficulty; sleep disruption; dehydration; dermatitis; eczema; virus, bacterial or other pathogen infection; respiratory infection; skin irritation; and throat irritation. The characteristic of the individual or group of individuals associated with the indoor space may include one or more of: age of the individual; gender of the individual; geographic location of the individual; race of the individual; height of the individual; weight of the individual; body mass index of the individual; marital status of the individual; an allergy associated with the individual; an indication of an amount of sleep by the individual during a prior time period; an indication of a recent sleep pattern by the individual; an indication of a sleep pattern by the individual during a prior time period; an indication of an amount of physical activity by the individual during a prior time period; an indication of an amount of movement by the individual during a prior time period; an indication of an amount of time the individual was present in the at least one indoor space during a prior time period; an indication that the individual currently is located in the at least one indoor space; an indication that the individual currently is not located in the at least one indoor space; at least one current medical condition of the individual; at least one prior medication condition of the individual; a sensitive group that the individual is a member of; and medical history of the individual. Such information may be associated with a user identifier in the user database 364. In some embodiments, the user database 364 may include receive or store data related to a user profile or account. [00157] The system 300 may further include one or more wired or wireless input devices 370. The input devices 370 may be communicatively coupled to the central control circuit 350. In some embodiments, the input devices 370 may be coupled directly to the air handling unit 340 or to devices therein. The input device 370 may allow a user to view and/or control functions of the system 300, as well as the air handling system 340, directly. In some embodiments, the input device 370 may include a display that may display, for example, one or more set points for system 300. The input device 370 may also include user actuatable controls (e.g., user selectable icons displayed on touch screen, keys, buttons), manipulation of which allows a user, for instance an occupant, owner, or manager of the indoor space, to select parameters or programs to control one or more components of system 300 and/or the air handling unit 340. In some approaches, a mobile or handheld device may serve as the input device 370 and may include a display (e.g., LCD) to display information and user actuatable controls (e.g., user selectable icons, keys, buttons) manipulation of which allows a user, for instance an occupant, owner, or manager of the habitable environment, to select parameters or programs to execute to control one or more components of the system 300. The mobile or handheld device may execute a downloaded customized application or “APP” that communicatively interfaces via a wireless protocol (e.g., IEEE 802.11, BLUETOOTH®, WI-FI®, Zigbee, Z-Wave, LTE). [00158] In some embodiments, the input device 370 may be a biometric device, such as a wearable biometric device. The biometric device may be configured do monitor one or more biometric parameters of a user wearing the device, such as an individual associated with the indoor space. In one example, the biometric device may be configured to monitor one or more sleep metrics associated with an individual of the indoor space. Such sleep metrics may include, for example, number of awakenings, sleep onset time, wake-up time, total time in bed, average sleep heartrate, and hours of sleep. In another example, the biometric device may be configured to monitor one or more activity metrics for an individual associated with the indoor space. Such activity metrics may include, for example, heart rate, steps per day, calories burned, resting heartrate, heart rate variability, and other vital signs. [00159] In some approaches, the system 300 may utilize data and/or information received from such input devices 370 to determine a humidity set point associated with the indoor space. The system 300 may also transmit one or more messages, alarms, or notifications to an individual associated with the indoor space via an input device 370 associated with the individual. The system 300 may also send one or more questions, surveys, or questionnaires to an individual associated with the indoor space via an input device 370. In one example, the questions, surveys, or questionnaires may solicit information from the individual regarding one or more health concerns, characteristics, or preferences associated with the individual. [00160] As illustrated in FIG.3, the various components of the system 300 for determining a humidity set point for an indoor space may communicate directly or indirectly, such as over one or more distributed communication networks, such as network 390. For example, network 390 may include LAN, WAN, Internet, Cellular, Wi-Fi, and other such communication networks or combinations of two or more such networks. [00161] In operation, the system 300 may be used to implement one or more of the methods described in FIGS.1 and 2 or portions thereof.
