| Abstract |
This study confirmed the necessity of a TAB (testing, adjusting, and balancing) practice for a ventilation system in residential buildings. Sixty small-scale buildings installed with heat recovery ventilation systems were selected to investigate the building energy performances of pre/post TAB practices for the heat recovery ventilation systems. The results of the pre and post TAB practices are as follow. Before the TAB practices, buildings under the positive air pressure showed 23.3% difference of the amount of air supply on average; those under the negative air pressure at 26.8%. TAB practices can reduce the cooling energy demand by up to 15%, on average 1%, and heating energy demand by up to 34%, on average 5%. |
