Energy-saving experimental house in hothumid climate of Malaysia

Abstract

In 2015, we constructed a full-scale experimental house in the city of Johor Bahru, Malaysia, in order to determine comprehensive energy-saving modification techniques through passive cooling for existing urban houses in the hot-humid climates. First, this chapter presents the results of numerical simulation to examine optimum combinations of modification techniques for the urban houses. Second, this chapter analyses the results of full-scale field experiments conducted in the above-mentioned experimental house to confirm the resulting effects of proposed modifications. The proposed modifications include (1) roof insulation, (2) external wall outer insulation, (3) external shading, and (4) forced ventilation (for the whole house and for the attic).
