Thermal Performance Modelling of Residential House Wall Systems

The energy consumption in residential house sectors contributes enormously to the greenhouse gas emission and soaring energy bills. Energy efficient residential house envelopes can reduce our dependency on fossil fuel and environmental pollution. It is difficult to achieve high energy savings for ongoing heating and cooling with currently used mainstream residential house envelopes. A new energy smart house wall system is required to achieve energy conservation. Therefore the main objective of this study is to investigate the thermal performance of a new house wall envelope and compare its performance with a conventional house envelope. The study was undertaken for several climate zones encompassing all major cities in Australia. The findings indicate that a considerable energy saving can be achieved using the new house wall system.
