Zero Carbon Challenge Winner
Team Collaborative Futures is an offshoot of Cundall engineering group and offered an intelligently design house that was attractive, sustainable and comfortable, all within the $330,000 build budget.
As part of Land Management Corporation’s Zero Carbon Challenge, we trained the Collaborative Futures team to conduct their own LCA and certified the results which decided the winner of the competition.
The summarised results of this project:
| Impact Area |
Total CO2e / Year / occupant (kg CO2e) | % Saved Against Benchmark | eTool Medal |
| Embodied Carbon | 786 | 15 % |  |
| Operational Carbon | -1,203 | 1141 % |  |
| Total Carbon | -417 | 111 % |  |
Project features
- 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)
- 7.5 star rating thermal performance requiring minimal air conditioning
- 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
