Project features
Materials
- Being a custom architectural design the design life is expected to exceed that of a normal Australian house, hence better use of materials before demolition
- Excellent use of space, very comfortable design with low material use and land footprint per square metre of fully enclosed building area
- Low embodied carbon timber frame construction
- Reduced maintenance with natural finishes such as polished concrete floors
- Local materials, suppliers, and tradestaff
- Low carbon assembly techniques (less transport of trade staff to and from the building site)
Operational Energy
- Low energy use, low carbon, high efficiency evaporative AC unit and bio-fuel heating
- Evacuated tube solar hot water system with gas boost
- 3kW Solar PV system that will generate more energy than the house will use
- Smart household energy management and security system options.
- The latest energy-efficient lighting, electrical appliances and water fittings
Additional Features
- Local materials, suppliers, and tradestaff
- Low carbon assembly techniques (less transport of trade staff to and from the building site)
- 7.5 star rating thermal performance requiring minimal air conditioning
- Breathable roof and wall wrap for weather protection and to significantly reduce unwanted air leakage while maintaining indoor air quality
- Correct site orientation and plan layout to maximise solar-passive strategies
- Double glazing to all windows and glazed doors to reduce unwanted heat loss and heat gain
- Superior draught-sealing and weather-stripping around all windows and doors to reduce unwanted heat loss and heat gain
- Above or in-ground rainwater storage for flushing toilets and garden irrigation
- Water recycling options
