| Abstract: | This paper discusses the feasibility of reducing heat transferred into houses (insulation effect) and inducing natural ventilation by using a modified Trombe wall (MTW) under ambient conditions in Bangkok. It consists of a masonry wall, air gap and a gypsum wall which are common construction materials. It was found that the MTW with 2 m2 of surface area, 14 cm air gap and dark in colour induced the highest natural ventilation rate, about 20–90 m3.h?1. The light colour of the wall induced the lowest rate, but was still significant for the ventilation of houses. With such air flow rates, there is little potential to induce sufficient ventilation to achieve thermal comfort of the house, however, the proposed configuration of the MTW should be recommended for constructing new houses, mainly, because of its high insulation effect. |
