To improve a real-time property of air-conditioning feedback control or power consumption display in a communication machine room in a communication building, data center, or the like.

A high speed data calculation processing optimization support system comprises: a reception data management function unit for performing approximation processing on measurement data from a sensor; a scale map management function unit for determining whether or not the measurement data on which the approximation processing is performed agrees with numeric data; a calculation processing control function unit for acquiring a code previously arranged to each of the numeric data when it is determined that the measurement data on which the approximation processing is performed agrees with the numeric data; and a code processing function unit which acquires an expression for calculating a combination for permitting repetition preset in a storage unit and acquires a corresponding calculation result, when the number of combinations obtained by multiplying an effective scale range as many times as the number of sensors exceeds the number of repeated combinations obtained by extracting numeric data as many as the number of sensors from a scale map including the numeric data of a predetermined type.
