Adding zero net carbon to existing energy efficiency assessments
Volume home builders are companies that construct a large number of homes from existing designs. Thermal performance assessors are accredited professionals focused on measuring the efficiency of building shells. In this pilot program, Sustainability Victoria wanted to look at sustainably-designed homes that factor in daily energy use – like people cooking and showering. The idea was to help volume home builders draft (and market) designs for new homes that met the Zero Net Carbon Homes program standard from the outset. This is where the Zero Net Carbon tool came into play – it would calculate the energy use of the home’s fixed appliances like lights and heating to help the design gain a zero net carbon ‘pass’ rating. Early in the research phase, it became clear that success would rely on making it easy for assessors to pick up the tool and run with minimal training.
