Energy Efficiency Assessments
House & Residential Energy Efficiency Assessment
NatHERS (Nationwide House Energy Rating Scheme) house ratings use computer simulations to determine the potential thermal comfort of Australian homes on a scale of zero to 10 stars. The more stars, the less likely the occupants will need cooling or heating to stay comfortable.
The minimum design documentation required when modelling a dwelling is:
• site plan — including a north point
• floor plan/s
• construction material details
• lighting location plan/electrical schedule
• window, skylight, roof window and door schedule/details including size, glass and frame type, opening style, location
Energy consumption by hot water systems, lights or household appliances is not considered in the rating because these fittings are usually replaced several times during the life of the building.
Sandy is an ABSA Accredited Assessor and uses Bers Pro software to provide a NatHERS Specialised Assessment Certificate for each new dwelling .
