Abstract
The purpose of this study is to make an economic analysis(Life cycle cost) of selecting optimal air conditioning system for a research building which is 8 stories with a total floor area of 32,010 ㎡. Energy consumptions of three proposed air-conditioning systems(Alt-1,2,3) that reflect the government green-growth policy are calculated and compared. The results show that life cycle cost of Alt-3(Ventilation DX AHU+EHP) is less than Alt-1(EHP+ventilation DX AHU) by 5.1%, and Alt-2(Absorption chiller/heater+EHP) by 34.3%. Annual energy consumption of Alt-3 is less than Alt-1 by 9.9%, and Alt-2 by 37.4%. Annual CO2 emission of Alt-3 is less than Alt-1 by 9.9%, and Alt-2 by 0.2%.
