Sustainable low maintenance features

This project involved the construction of a low rise residential development for a not-for-profit organisation aided by the Federal Government stimulus package for assisted housing.
The project scope involved construction of five units and a common building comprising staff accommodation, cooking area, wet area rooms and lounge. Coordination of the design process and the execution of construction works was carried out in collaboration between Fairbrother and GHD. The key challenge was to deliver a quality product using local subcontractors within tight time constraints and through careful project management, effective site management, quality workmanship and an excellent client-contractor relationship, the project was delivered on time and under budget.

The units incorporate numerous sustainable features such as a low maintenance façade with colourbond cladding and fibre cement sheet weatherboards, double glazed windows and door units, rainwater collection tanks for WC use, Dux heat-pump hot water cylinders, external and internal wall insulation to R2, and a well insulated light steel roof to R4 with minimal valleys to reduce the heat load required for each unit. Solar orientation of the common building is along a northeast-southwest alignment with the majority of the glazing aligned to this axis; this makes best use of the available natural daylight whilst minimizing heating loads on the building. The landscaping is communal and there are no fence lines which helps to promote mixing of the tenants.
