Application of renewable energy sources and new building technologies for the Philippine single family detached house

The Philippine residential sector consumes a large percentage of the country’s generated electricity, and the price of electricity there is one of the highest in Asia. With a government program in renewable energy utilization and energy efficiency, the development of energy efficient houses is important. This paper presents a numerical investigation on how to minimize the house’s energy consumption, and theresults show that a house’s electricity consumption can be supported by the installation of solar photovoltaic panels on itsrooftop. A solar thermal collector with an auxiliary biomass water heater could support the hot water requirement of thehouse. The desiccant dehumidification system combined with evaporative and ground cooling systems can keep the house’sindoor temperature below 27 °C with a humidity ratio of less than 11 g/kg year-round. Energy conservation measures suchas additional insulation of a concrete house, unplugging of unusedelectrical appliances and application of light-emittingdiode lighting are important to reduce electric energy consumption. The application of new building technologies is having a positive impact on a building’s energy consumption and indoor environment conditions. The results of this studyare important for the Philippine programin alternative energy utilization and energy efficiency.
