Recycled and reclaimed materials are fitted throughout the Abbotsford Eco House, a sustainable residence that earned a 7.5+ NatHERS rating for its energy-efficient features. Design and planning company First Angle completed the project for a client seeking a sustainable low-impact home in Melbourne. In addition to using recycled construction materials, the designers also turned to recycling in other parts of structure – from recaptured heat to recycled rainwater and treated gray water.
The Abbotsford Eco House was built largely from materials sourced from the original home on site as well as reclaimed materials taken from local second-hand shops. To minimize energy usage, First Angle placed the residence on a north-east orientation for optimized cross ventilation and solar access for natural heating. Concrete mass stone-clad walls and polished concrete floors throughout the home capture heat during the day and dissipate it at night. Hydronic heating installed in the insulated concrete floor slab complements the natural heating. The designers also take advantage of the stack effect to naturally cool the home in summer.
High-performance woolen thermal insulation and double-glazed windows help lock in internal temperatures. Harvested rainwater is reused for flushing toilets and irrigation. A treatment system filters and recycles gray water throughout the home. The interior decorating also echoes the eco-friendly ethos with some of the pieces also salvaged and repaired.
