Abstract

Energy has undeniable role in sustainable architecture. Building sections consume 15 to 60% of whole energy in different countries. Residential sector includes 19% of energy consumption in Malaysia. In this study, a bungalow house as a common low density house in Malaysia was simulated by Design Builder software based on Energy plus program. Then its different components including floor, wall, roof and their influence were explored by simulations of various alternatives. Results showed that naturally ventilated raised floor in first floor with 19 mm wooden material could save 9.4% of cooling electricity. Changing wall detail of first floor (naturally ventilated floor at night time) from heavyweight to lightweight could save 16% of cooling energy and replacing white painted steel instead of concrete tile could decrease 5.8% more cooling energy. Composition of these components in proposed house presented 28.3% cooling energy saving.

Key words: Cooling energy, floor, wall, roof, bungalow house.
