| Abstract | Air infiltration through building envelope is considered as a path of outdoor air ventilation in modernThai detached homes where there is no outdoor air intake in an air condition unit. At present, there are limitedstudies of air infiltration rate through building envelope for Thai homes and such few studies are insufficientfor establishing a database of air infiltration rate for evaluating home energy performance. This present studyused a multi-zone airflow model to calculate air infiltration rates in 134 homes from 137 housing developmentprojects located in suburban areas near Bangkok. The calculated air exchange rate (air infiltration) ranged from0.33-0.58 h-1 with an average value of 0.43 h-1 (s.d. = 0.04). Compared to the ventilation standards, the calculatedair exchange rates were approximately 1.7 times greater than the required ventilation rates defined bythe ASHRAE Standard 62.2 (2007) and 93% of those achieved the required ventilation rate prescribed in theThai Building Control Act B.E. 2522 (2015). Consequently, it has a potential to reduce air infiltration rate formodern Thai detached home to save home energy consumption. The default air infiltration rate typically usedin energy models provided a maximum input error ranged from 7-65% when compared to the calculated airinfiltration rates. |
