Influence of Energy Efficient Elements on Energy Saving in Residential Buildings: Case Study of Three Apartments in Penang

Abstract

This paper examined the energy consumption of energy efficient buildings, and ascertained the extent to which these buildings are efficient when compared to normal buildings. For this purpose, the early literature regarding energy efficient buildings and the related elements have been reviewed, then three energy efficient buildings have been chosen and data collected from their occupants through a questionnaire. The data was then analysed by computing the average yearly electricity consumption per square feet, for both energy efficient buildings and normal buildings. A comparison of the results showed that the energy consumption in energy efficient buildings was almost half that of the normal buildings. Finally a few suggestions are proposed for promoting these types of energy efficient buildings which will eventually lead to economic growth and environment protection.
