Abstract

Properly designed ventilation in a house built in a hot and humid climate will provide adequate fresh air, but during hot weather this ventilation will introduce more moisture in to the house. Also, approximately 30–50% of the energy used for air conditioning for cooling is lost through air infiltration. These issues could possibly be addressed by making the envelope of tropical housing more air-tight. The objective of this study was to determine energy-saving modifications through the application of Passivhaus principles to Jakarta urban houses. This paper investigated the effects on indoor temperature, humidity, comfort and energy use of gradually improving insulation levels and airtightness to meet the Passivhaus standard. This study analysed the effects of air conditioning (AC) and dehumidifiers on thermal comfort and cooling load through numerical simulation using IES VE software. Some design recommendations result from the analysis.
