The comparison of thermal performance between a Bio Climatic House and a Typical House

Abstract

This research was conducted to compare thermal performance between a Bio Climatic House and a Typical House. Both houses had a volume of 25 m3. As a Bio Climatic house, a solar chimney (SC) was attached to a Roof Solar Collector (RSC) that consisted of CPAC Monier tiles with a funnel 14 cm width and gypsum boards. The design of the partial roof was transparent to allow light pass into the house by the reflection of light. However heat could not enter the house. The walls were Modified Trombe Wall (MTW) which was made of plywood while and had ventilation channel of 14 cm. width that turned to the south. The experiment was set on January 2013 to February 2013. On the other hand, a Typical House was modified from the former house with neither Modified Trombe Wall (MTW) nor Roof Solar Collector (RSC). The experiment was arranged on April 2013 to May 2013. As a result, the conclusion indicated that a Bio Climatic House (BCH) had lower room temperature than ambient temperature 2-3o Celsius because hot air flowed out via the roof and the walls. In comparison, a Typical House had higher room temperature than ambient temperature. Thus, residents in a Bio Climatic House (BCH) would feel more comfortable than a Typical House.
