In this study, sensitivity analysis based on multiple regression analysis was conducted to determine the effects of changes in the thermal transmittance of the exterior wall, the extrior roof, the lowest floor, and window of the hospital selected as the target building on the sensible load. The results show that the heating load of the target building is sensitive in this order : the thermal transmittance of the window, the exterior wall, the extrior roof, and the lowest floor.
And the cooling load of the target building is sensitive in this order: the thermal transmittance of the window and the lowest floor. To suggest the envelope performance improvement, cost effectiveness of the amount of sensible load savings and material cost of each cases based on the ECM (Energy Conservation Measure) list was analyzed. In the end, the method that can reduce the most sensible load savings with the lowest material cost was produced.
