Effectiveness of energy-saving renovation techniques through passive cooling for urban houses in hot-humid climate of Malaysia

The main objective of this study was to examine the effectiveness of energy-saving renovation techniques through passive cooling for urban houses in hot-humid climate of Malaysia. Effects of two strategies, i.e. complete natural ventilation (NV) strategy and partial air conditioning (AC) strategy, w...
