| Abstract
|
:
|
In a hot and humid tropical region, the air’s moisture level is high. The external humidity levels are very high in hot and humid tropical regions, thus using natural ventilation to reduce indoor humidity levels due to occupant activities is not effective. The use of air conditioning to cool rooms and reduce relative humidity in dwellings is an energy-intensive approach and it is also energy-inefficient as the conditioned air is lost through the building envelope via ventilation and air infiltration. The German Passivhaus standard’s approach in tropical housing might be effective in preserving stable interior temperatures, however special attention is needed regarding the removal of excess moisture. The aim of this research was to investigate the thermal comfort and energy-saving implications of applying Passivhaus principles to existing urban row houses in Jakarta, Indonesia. The goal was to achieve minimum carbon emissions whilst maintaining a comfortable environment. This thesis investigates the feasibility of the Passivhaus standard in the context of Indonesia by comparing the performance of the two buildings models in terms of energy savings, and thermal comfort, using dynamic thermal simulations. The building model was created from the case study information and was validated using realtime monitored data. The thesis will investigate the effects on indoor temperature and humidity on comfort and energy use by gradually improving insulation levels and airtightness to the Passivhaus standard, to find the optimum setting for reducing cooling and dehumidification energy in air-conditioning. This study examined the effects of air conditioning (AC) and/or dehumidifiers on thermal comfort and cooling load through numerical simulation using the PHPP, DesignBuilder and IES VE software. The findings highlighted the potential energy saving and at the same time bring comfort to the rooms by applying the Passivhaus standard. Assessments of the results enabled the optimum insulation and air-tightness settings to be determined for minimizing cooling and dehumidification energy use in the air-conditioning system. The research highlighted the potential energy saving from removing the floor insulation of the Passivhaus standard. The research concludes with several key features that could possibly be applicable in the context of hot and humid climate, and which highlight the possibility of a promising transition towards low energy buildings that are ready to face the region’s future challenges.
