The effects of rooflights on energy performance of a commercial retail building in a sub-Tropical and a temperate climate

Abstract

The research aims to develop an energy efficient solution by predicting nature of energy use for a retail building with Rooflights in a sub- Tropical and a temperate climate of Australia. The research highlighted in the study include (a) the maximum amount of Rooflights area that can make a retail building energy efficient; and (b) the effects on other building elements for the increased use of Rooflights. The study demonstrates that maximum 20% Rooflights of a conditioned space can be applicable for a retail building for an energy efficient solution i.e. improvement of annual energy saving (kWh/yr). To achieve this, building elements such as glazing, insulation, and colour need to be changed.
