The Performance Of Pcm-Enhanced Walls For The Reduction Of Peak Indoor Temperature In Tropical Climate

The Performance Of Pcm-Enhanced Walls For The Reduction Of Peak Indoor Temperature In Tropical Climate

Buildings in Malaysia suffer from high indoor temperatures due to the hot and humid tropical climate, which results in extensive use of air-conditioning for cooling. The building sector is one of the main contributors to high energy consumption and the associated greenhouse gases emissions. However,...
