Abstract

This study concerns an investigation into the thermal performance and energy efficiency of prefabricated lightweight houses for peri-urban villages in the Perth Metropolitan region of Western Australia. Several styles of residence were selected for comparison, taken from the first three “lifestyle villages” constructed by National Lifestyle Villages Pty Ltd (NLV). NLV is committed to quadruple bottom-line sustainability and the aim is, therefore, to provide indicators of how old and new dwellings compared under the same external conditions.

The buildings themselves are prefabricated and brought to site in two halves, framed in steel, clad with fibre-cement boarding, roofed in zincalume sheeting, floored in flooring grade particle board with applied fibre-cement sheeting. Although the basic design was developed using the passive principles of solar design and other energy conservation measures, they possess little thermal mass to augment the thermal efficiency. Research has indicated several feasible and low-budget innovative improvements to incorporate into future designs, and how best to modify and retrofit existing dwellings.

NLV aims to provide homes for over 40,000 people in 100 villages throughout Australia by the year 2025. Any improvement in residential thermal performance can be translated not only into energy savings and greenhouse gas reduction on a significant scale, but can enhance comfort levels for residents whilst reducing their energy costs.

This paper will present the data and report on the results of the investigations. Recommendations will be made for housing in proposed future villages with regard to requirements for other improvements such as innovative means of increasing internal thermal mass.
