Support system for improvement and prediction of the energy performance of an apartment envelope in schematic design

Establishing the appropriate measure for estimating and improving the energy performance of a new building is very important at Schematic Design. As an initial attempt toward this end, this research sought to determine at Schematic Design if the designed apartment envelop structure ensured proper energy conservation performance and to develop a support system that could suggest for the envelop structure an improvement measure meeting the targeted energy conservation performance depending on whether or not the calculated value was satisfactory. Specifically, the calculation method for the building energy efficiency rating system based on which the amount of apartment energy conservation could be calculated was applied to determining the performance of the apartment envelop structure. EnergyPlus, a program for interpreting energy, was used for building energy interpretation to suggest an appropriate envelop structure. In addition, the process of setting a specific part suggesting the appropriate envelop structure for the improvement of performance of envelop structure energy was developed by introducing AHP and Fuzzy Logic technique.
