Abstract

A preference for low-density housing by Indonesian people has contributed greatly to uncontrollable urban sprawl around the peripheries of Indonesia's major cities. The cooling of low-density housing to maintain thermal comfort is energy intensive, with approximately 30-50% of conditioned air lost through ventilation and air infiltration. As Indonesia is in a hot and humid climatic region, the air's moisture level is high, and ventilation during hot weather can introduce more moisture in to buildings. Thus, the removal of excess internal humidity is essential for human comfort. The German Passivhaus building standard is effective in preserving stable interior temperatures, but its air-tight envelope might hinder the removal of excess moisture in tropical climates. The dynamic thermal simulation software DesignBuilder was used to model a typical Jakarta terraced dwelling to investigate the effects on indoor temperature and humidity on comfort and energy use from applying the Passivhaus standard. The aim was to find the optimum setting for minimising cooling and dehumidification energy in air-conditioning systems. The research examined the type of active dehumidification system that might be most suitable to work with a Passivhaus in tropical conditions to position the house's internal environment within the thermal comfort zone.
