Comparative assessment of passive design strategies for improving indoor thermal comfort of low-cost house in hot–humid climate of Malaysia

Research output: Contribution to journalArticle

Abstract

The prime objective of this study is to investigate the passive design strategies and their potential application for improving the indoor thermal condition of naturally ventilated low-cost single story detached houses in Malaysia. In order to fulfil the objective, field measurement was conducted on a typical low-cost single story detached house in Kuala Pilah. The results show that the indoor air temperatures were much higher when the windows and door were closed (condition 1) rather than the temperature with the open windows and door (condition 2). Indoor air temperature inside the house is not between the recommended temperature ranges of Malaysian standard. The emphasis was given to reduce the indoor air temperature by initiating passive design strategies to ensure a good thermal environment. Roof insulation, larger openings, and shading devices can be the potential passive design strategies for the existing low-cost single story detached houses. In this paper, indoor air temperature of the master bedroom (MB) area has been simulated with glass wool insulation, shading devices and larger openings in IESVE software for comparing the passive design strategies. The results later revealed that at daytime, indoor air temperature data obtained from the simulations with larger openings and shading device were more like the base model simulated results. Apart from that, the indoor air temperatures decreased mostly while simulated with glass wool roof insulation. Moreover, the indoor air temperature of the master bedroom area dropped down to 2.1°C and 0.7°C when glass wool insulation material used under the regular metal deck roof of the house under condition 1 and condition 2 setups respectively.
