Description:
ONE ADVANCED SHADING DEVICE

Technical Field

The invention aims to develop an integrative shading unit for high-rise building in hot climate zones, that can act or perform not just as a shading device, but comprehensively by controlling four main factors (The occupants adaptive comfort level, daylight, ventilation, and energy generation) at the same time and the same system to regulate the level of the performance and the energy efficiency of a high rise-building.

Prior Art

Buildings are exposed to various environmental and climatic conditions that determine the quality of the indoor environment and thus the occupants comfort level. Therefore, Facade is the most important parts that determines the performance level and the energy efficiency of the building in general. Because, facade is the barrier that separate the interior space from the exterior environment and maintain the indoor conditions comfortable as much as possible.

In general, there are four factors determine the performance of any building which are: The occupants adaptive comfort level, Daylight, Ventilation, Energy generating.

The conventional shading systems started as a fixed external or internal devices placed on the windows and above the doors with sufficient depth to prevent the sun radiation all the year (winter or summer). After that, the shading systems have got some flexibility by moving up and down or left and right to regulate the shading blades or fins accordingly. But the most recent shading systems are the interactive kinetic shading devices using sensors to open and close. In general, the shading devices in all over the world still limited with just one function ability which is the shading function to prevent the sun radiation pass through.

In addition, the shading systems cover a huge area of the building facade without any further functions to exploit the perfect conditiones. So, some buildings especially high rise building have a great potential to exploit multiple conditions and contribute to enhance the performance and the energy efficiency of the building but the conventional shading systems don’t consider these potential conditions such as ( using the sun to generate energy, exploit the height and the huge area for wind turbines and micro wind turbines, using the form’s physical properties to increase the efficiency of ventilation and energy generating, control the opening and closing to block the direct sun radiation and increase the efficiency of daylight, etc...)

The shading systems are used throughout the year to control the sun radiation and manage the solar heat gain. One of the challenges when selecting these systems is how to develope a shading solution that meets the specific project requirements. The shading system is a treatment prossess influenced by multiple aspects like climatic parameters, facade design, orientation, and glazing type. Some buildings have already their way for self-shading designed and other need for additional treatments such as shading devices, glazing type, construction materials. However, there are many types of shading devices that could be classified based on many aspects such as fixed shading devices or movable shading devises. The movable shading devises mostly called the kinetic shading systems which have the ability to move or interact. In general the kinetic (movable) shading systems are the most recent and developed systems have been used in building.

Aims of the Invention and Brief Description

The present invention is related to eliminate the disadvantages mentioned above and to bring new advantages to the related technical field.

In general, there are four factors determine the performance of any building which are: The occupants adaptive comfort level, Daylight, Ventilation, Energy generating.

The invention aims to develop an integrated shading unit for high-rise building in hot climate zones, that can act or perform not just as a shading device, but comprehensively by controlling all the four main factors at the same time and the same system to regulate the level of the performance and the energy efficiency of a high rise-building. The integrative shading unit combined multiple systems to manage these four factors as follow.

-Adaptive occupant comfort level (cooling & heating demands), by using the unit’s material as a shading system to block the sun radiation.

-Daylight, by using the unit’ s sensor to control the opening and closing to increase the daylight efficiency and reducing the artificial lighting demands. Another aspect that can increase the efficiency of the daylight function in this shading unit is the use of a translucent material with minimum visible lighting transmit level to prevent the sun radiation and allow to a minimum level of daylight to pass through. -Ventilation, by using the unit’s concave hexagonal form and system design to enhance the efficiency of the ventilation system by increasing the capability to capture the fresh air and increase the velocity on the air intake-hole.

-The prior factor in this project is the contribution in energy generation, the project has the ability to re-form itself and transfer its function from shading unit to wind turbine for energy generating purpose. The unit has a transformable form ability by taking a wind turbine form when the wind speed reachs the minimum wind speed rquierd for the wind turbine. As well as, using a micro wind turbine all the time(requiers low wind speeds relatively). The efficiency of the micro wind turbine increase when the shading unit take the full shading position due to the concave hexagonal form (created when the unit at the full shading position). In addition, the integrative shading unit has a frame of solar panels. Engineers have developed a new photovoltaic system called Ruukki, which could be fully integrated into a facade. The new system can produce power even in spaces without direct sun light.

So, the major aim of the project is to create an advanced- integrative shading unit with four functions ability.

Breifly, the invention created logical solutions to increase the efficiency of the existing shading devices and developed their capability as a shading unit into integrated units that can carry out as many activities as necessary for the building at the same time. The project can shade the below layer (glazing, walls, etc...) that needs for shading. But in the areas that don’t needs shading (measured by sun sensors and software), the units will be transferred to the wind turbine position. Also, the units can control the daylight level by controlling the opening and closing level. Furthermore, the project has its system to increase the efficiency of natural ventilation (concave form design). So, the project has four main function: shading (comfort level), energy generating (wind turbines & solar frame), daylight, ventilation. The invention seeks to obtain integrated shading devices that can perform four main functions for the building in addition to many other secondary functions. The invention tries to exploit the vast spaces and heights of the facades of the high-rise buildings to obtain high-performance, environmentally friendly buildings.

In general, the invention seeks to regulate the internal environment of a high-rise building with the lowest energy consumption and the lowest carbon emission. Definition of the Figures

The novelty of the invention has been described with examples that shall not limit the scope of the invention and which have been intended to only clarify the subject matter of the invention.

The present invention is related to shading device which provides to control the occupants adaptive comfort level, Daylight, Ventilation, Energy generating for buildings.

The present invention has been described in detail below.

THE IDEA OF THE INTEGRATIVE SHADING UNIT

Biomimicry: cactus skin inspiration:

• The cactus skin has a number of stomata, but the number of stomata per square area, however, is less than the number for normal plants. So, it is a water-saving characteristic.

• The cactus skin has a waxy layer represents the main line of resistance to hot climate by isolating the plant core from external heat and prevents it from affecting the plant. The waxy layer prevents the water vaporization. Also, the waxy layer is lightly colored and reflects some of the direct sunlight.

Biomimicry: construction application:

• In the building design process, reducing the direct opening to the external environment (windows) per square area may offer a reasonable solution to maintain the comfortable conditionings inside the building as much as possible in hot climate.

• Also, the glazing layer represents the same function as the waxy layer to protect the inside, to prevent the loss of comfortable indoor conditions, as the main line of resistance.

• So, the glazing layer needs to be considered not just as a random best choice, but to be optimized to fit the multifunction layers (shading units and other structures) of the system as much as possible (figure 2)

Use one of the most efficient shapes to occupy the spaces found in nature which is the hexagonal system for bouth glazing structure layer and shading unit layer design. Also, increase the depth of the shading unit from the central region making a concave hexagonal form to increase the efficiency of air-intake system for natural ventilation and micro-wind turbine systems (figure 3) and (figure 4) THE STRUCTURE LAYERS:

Yet, the construction process for the shading units to make the whole facade system, consist of four structure layers: glazing structure layer, The main exterior supportive steel structure layer, Shading units’ layer, Solar panels structure system layer.

1. Glazing structure layer (figure 5)

2. The main exterior supportive steel structure layer (figure 6)

3. Shading units’ layer (figure 7)

4. Solar panels structure system layer (figure 8)

THE MOVEMENT ABILITY OF THE SHADING UNITS:

The units have the movement ability to close and open by using sensors system to trace sun path and prevent the direct solar glare and radiation to pass through glazing layer. And allow to the units on the opposite sides of the solar radiation to be opened (figure 9)

This process can increase the daylight efficiency and reduce artificial light demands.

Furthermore, this process might affect all the main four functions in different levels:

• Cooling & heating demands (Adaptive occupant comfort level) in this function using sensors system to control the opening and closing.

• Daylight, by using the unit’s sensor to control the opening and closing to increase the daylight efficiency and reducing the artificial lighting demands.

• Ventilation, the full shading position increasing the capability to capture the fresh air and increase the velocity on the air intake-hole due to the concave form physical properties.

• Contribution in energy generation, by using the unit’s transformable form ability to take a wind turbine form for the units with folding position (no shading )when the wind speed reachs the minimum wind speed rquierd for the wind turbine. But, the efficiency of the micro wind turbine increase when the shading units take the full shading position due to the concave hexagonal form. So in general, the transformable steps of the integrative shading unit can be classified into four steps:

• Position A: is the full shading position in the movement steps. The position A used at the business times to shade the facades with direct sun position (figure 10)

• Position B : is the 50% of the full shading position in the movement steps. The position B used mainly as a transitional step. Also, it could be used with sensors system to control the level of effectiveness of the four purposes (figure 11)

• Position C: is the folding position in the movement steps. The position C used mainly as a transitional step. Also, it could be used with sensors system to control the level of effectiveness of the four purposes (figure 12)

• Position D: is the folding and rotatable position (with oblique blades) in the movement steps. The position D used mainly as a final step for the main wind turbine. Generally, it is used after business daytimes for energy generating (figure 13)

SHADING MATERIAL

• In this design, there are two options of shading material could be used according to the climate type and location. Which are defined physically as 1 -Translucent material, 2-Opaque material. These two physically properties could be maufactured as a Fiberglass material which is widely used recently in different purposes.

• Translucent material: lets spesific amount of light pass through, but objects on the other side can't be seen clearly in a number of translucent material manufacturing companies, the range of Visible Light Transmittance (VLT) is almost between (5% min- 30% max) and the 30% VLT is not recommended. Therefore, in this design the 5% of VLT can be used as a minimum range that can give an approximate perception of the daylight benefit.

• Opaque material: has the ability to block the direct solar radiation and direct daylight completely. Opaque material with high reflectivity can mitigate daylight loss at some level. THE TWO TYPES OF THE SHADING UNITS

Portable shading unit (19) (Type A), is a portable type in the shading system with 6 supportive structure arms in the front of the shading unit to mitigate the vibration affect for the whole shading system (Type A, B). The portable shading unit (Type A) has the central intake hole placed in the middle of each space (on 2 meters’ height from each floor). So, this unit type designed to be carried by the other type through the exterior connection structure that transmits loads to the type B. The portable unit has the ability for direct nutral ventilation by a small window leads directly to the indoor space. The small window controlled (open and close) manually or automatically (using computational system). The unit has the air intake hole coverd by perforated cover to control the wind speed pass through (figure 14)

Carrier shading unit (20) (Type B), is a carrier type of the shading system, which has the central intake hole placed on the above floor of each space (or ceiling) on 4 meters’ height from each floor. So, this unit type has the strongest structure due to the direct connection to the floor structure and also has a special column designed to carry the whole shading system.

• The carrier shading unit (20) has a micro wind turbine applied on the air intake hole. Also, the carrier unit mostly used for the main ventilation system by connecting the air-intake hole (with the micro turbine on it) to the air ducts system (in the floors and ceilings).

• Type B unit is mainly used for heights with a below average wind speed that required for the main wind turbines. So, the micro wind turbines applied only in type B.

• While, the main wind turbines can work with a specific wind speeds averages above (3.5 m/s) only. Which in general could be achieved on sufficient heights. The main wind turbines could be applied in the Type A or B units (figure 15)

THE FOUR MAIN FUNCTIONS (SYSTEM OPERATIONS! • The integrative facade system has been explored with its structure layers design, material and potential functions that can be achieved by this design. So far, as mentioned before the shading units have a potential to achieve four main functions:

1- shading (cooling&heating) 2- daylight 3- ventilation 4- energy generation.

Shading

• The integrative shading system applied to cover the whole affected facades (south, east, west) with the ability to control the opening and closing of the shading sub-units to regulate the sun radiation level pass through glazing layer, using sensors system and material options (figure 16)

Daylight

• artificial lighting energy demand based on scientific researches of a typical building located in tropical countries, takes the second position of priority which is less than air condition energy consumption by a huge disparity. Also, the system has the ability to control the sunlight level pass using sensors system and material options.

Ventilation

• The integrative shading system offer the ability to increase the efficiency of the natural ventilation process and reduce energy used for this process as another potential function (figure 17)

• The hexagonal concave shading units form facilitate the process of air intake and air distribution.

• The integrative facade system provides the building the natural air needed to make the building capable of breathing.

• The integrative facade designed to be able to ventilate the spaces that need fresh air always. Wc, kitchens, and the spaces with mechanical engines which produce heat and carbons. So, this system can provide fresh air directly without much energy using.

• The control system save energy by preventing the heat loss or gain by changing the air and allowing the spaces in need to exploit the fresh air.

• In general, the ventilation system (using the carrier units type B) divides into two parts. One part for providing fresh air. • The second part used to get rid of hot polluted and unwanted fresh air from ventilation system.

Energy generation

• High rise buildings have a great potential to exploit the environment conditions to generate energy.

• The integrative facade system offers two concepts of renewable energy technologies.

• The first technology is the solar panels.

• Engineers have developed a new photovoltaic system called Ruukki, which could be fully integrated into a facade. The new system can produce power even in spaces without direct sun light. The technology can also use sun rays in cloudy weather, in snowy places and near water, from reflected rays.

• While, the second technology in the integrative shading units, is based on the transformable units’ design (position D). The integrative units designed to be able to transform to a potential form which can influenced by air velocity as a wind turbine. In general, the wind turbines can work with a specific wind speeds averages above (3.5 m/s).

• In the integrative units design, the main wind turbines can be applied in each one of Type A and Type B units. But, the unit shold be located on a sufficient height with an verage wind velocity that exeeds (3.5 m/s). Therefor, the units on heights that do not reach the average (3.5 m/s) of wind speed, not need for main wind turbine to be installed.

• Therefore, a micro wind turbine which can work below the average have used in Type B units with local wind speed. So, the integrative units designed already with a potential shape (hexagonal concave) to captivate air as much as possible and increase the air pressure on the air intake holes where the micro wind turbine placed in Type B units. THE CONSTRUCTION PROCESS:

• Yet, the construction process of the shading units to make the whole facade system, could be present as follow figures

• The interior bearing column, is the interior supportive stractural part which is responsibal to transmit the units loads to the ground. This part, connect directly to the units Type B (carrier unit) and undirect to the Type A (portable unit) (figure 18)

• The hollow base, for air intake, purification, moisture absorption, and noise mutation from air velocity and wind turbine. This part must be lining with specific material fits the purpose. Also, this part connect to the interior bearing column from one side and to the main wind turbine (Annular generator) from another (figure 19) & (figure 20)

• The glazing structure, it is a hexagonal structure divided into 6 equal shapes for each unit (figure 21)

• The Main wind turbine (Annular generator + 6 sub-units’ movement axes), this part has the exterior air-intake hole connects to the hollow base. In general, the annular generator design allows to make the air intake hole on the wind turbine. The main wind turbine consist of the annular generator part which can rotate with wind speed above (3.5 m/s) for energy generating. Another part of the wind turbine is the 6 sub- units with 6 movement axes and actuatores to control the sub-shading units’ form and transform it to the rotatable oplaqe blades position (opening and closing) according to the sensores information. Also, the carrier shading unit (type B) (20) connected to the floor structure directly by joints parts (figure 22)

• Air ducts for ventilation system: noise mutation design from air velocity and wind turbine.

• The integrative shading unit consist of 6 sub-units.

• Sub-unit’s Actuators system, small actuators for each sub-unit responsible for the transformation positions (movement steps).

• Glazing option, optimized among more than four glass choices to choose not just random best choice available in market but the most efficient (optimum) one that fit the whole facade layers’ design and provide the best performance of the building (figure 23)

• Shading material, choose the best material option of the reinforced fiberglass (translucent or opaque material) according to the climate zone of the building.

• Solar panel, a photovoltaic system called Ruukki, which could be fully integrated into the unit’s frame. The system can produce power even in spaces without direct sun light (figure 24)

• Exterior bearing structure, is exterior steel structure connect to both units’ type (A and B) directly and transmit the loads to the ground directly (figure 25, figure 26, figure 27)

Some explanations of definitions:

High performance building: are the building which can provide an energy conservation, occupant comfort, or greenhouse-gas reduction, and sustainability more than other buildings.

Energy-efficiency in buildings: can be defined as buildings that are designed to provide a significant reduction of the energy demands for heating, cooling, lighting, and other equipments.

Biomimicry: is the term to describe the use of genius in nature. It basically aims to use resources in the most effective method while sufficient human needs. Generally, it is the use of the brilliant found in nature, which simply seeks to make the most efficient way of using resources to solve the problems. For instance, mimic the brilliant systems in nature such as forms, materials, processes, constructions, and functions.

Occupants adaptive comfort level: The adaptive comfort concept is a process based on certain weather data to measure the level of comfort times that occupants can adapt themselves to. Therefore, the adaptive comfort process built on the work of hundreds of field studies in which people in ventilated buildings were asked about how comfortable they were in other meaning, its the periods of times when people inside the building dont need for heating or cooling loads.

Dalyight: The building design should consider the visual comfort within natural daylight which significantly improves the health and efficiency of occupants, and reduce the energy used for artificial lighting in the building. Daylighting considered as an alternative to artificial lighting which offers the simplest method for energy efficiency. In more specific, it is the amount of light on a surface per unit area, and it measures by lux unit used to evaluate the brightness of inside space. HVAC (heatig, ventelation, and air conditioning): is one of the major operation factors connect to climate conditions in the building area. Also, the design and the environmental treatment such as shading devices and construction materials affect the energy consumption by HVAC systems. Recently, annual energy saving is a critical issue for the built environment by taking into consideration the peak load conditions which affect largely cost saving as well. However, the shading devices and glazing system are the most affected factors on the energy demand by HVAC in hot climates. The shading devices and glazing system directly linked to HVAC energy conception and comfort level.

Ventilation: In the past, the buildings have been ventilated by windows in general. As the design of the facades has changed, however, natural airflow controlled mechanically which is increasingly depends on. But, Mixed-mode offers potential concepts due to the abilities that the mechanical system can offer for energy-saving and increase the attention for passive concepts to the building ventilation system. Natural ventilation in high rise buildings has the potential of buoyancy and the stack effect to remove heat from the building envelope. Generally, the natural ventilation systems influenced by several factors in the design process such as orientation, thermal mass, and facade design. The building orientation, surface to volume ratio, and other factors must all be designed to maximize natural ventilation and reduce energy usage for it at early stage of the design process to guarantee the success.

Renewable energy generating technology: Recently, renewable sources of energy become more and more reliable especially within the tremendous progress in technology and engineering innovation. Renewable energy technologies provide marketable energy by changing natural phenomena into useful shapes of energy. The building sector has a large share of global energy consumption. Therefore, a new trend of integrated building with renewable energy generating technology towards energy reducing or even nearly zero energy building has appeared recently.

Kinetic or (moveble, transformable) system: is the system with the ability to move, transfor, change according to some parameters. This system can interact or adapte itself to dynamic data.

Wind turbine: large or medium size turbine (energy generatore based wind) that can generate power with specific wind speed (velocity) above 3.5 m/s.

Micro wind turbine: small size turbine that can generate electric power with different range of wind speed (high or low), Visible light transmit: is the amount of visible light that can pass through.

Based on detailed explanation above, shading device comprising;
