Apartment houses which are the most common type of residential buildings in Korea have the lower internal heat gain than office buildings. The envelope of apartment house is the important system affecting thermal bridges where the risk of heat loss and energy consumption increase. This study aims to evaluate integrated insulation performance different external wall shapes adjacent to windows in an apartment house by Equivalent U-value analysis using the three-dimensional heat transfer computer simulation. Building energy simulation is based on DOE-2.1 analysis for annual heating, cooling loads of an apartment house. For this purpose, H apartment houses located in Deajeon city was selected for the two-dimensional analysis of nine different shapes of the external wall before performing the detailed three-dimensional heat transfer simulation. The Equivalent U-value was evaluated by computer simulation (TRISCO RADCON) under nine different cases and the heating, cooling load were compared between two cases (standard U-value and Equivalent U-value). As results, it turns out that nine different cases showed the Equivalent U-value had 21 to 123 percent higher heat loss than those of existing U-value. Also the average Equivalent U-value(0.775W/㎡K) of the entire outer wall has 42 percent higher heat loss on average than those of existing U-value(0.45W/㎡K). In addition, annual heating loads of the target apartment house with applied Equivalent U-value substantially increased by 45.5 percent compared to those with the existing U-value, but annual cooling loads were negligibly affected. |
