Are there minimum energy-efficiency requirements?
Yes. New dual-occupancy dwellings must meet minimum energy-efficiency standards equivalent to 7-star NatHERS, together with applicable Whole of Home energy requirements. If the NatHERS pathway is used, at least 7 stars is required.
Yes. New dual-occupancy dwellings must meet minimum energy-efficiency requirements.
For new homes in the ACT, the standard is equivalent to a 7-star NatHERS energy rating. If the NatHERS/house energy rating software pathway is used, the dwelling must achieve at least 7 stars, including the applicable heating and cooling load limits. The ACT also has Whole of Home energy-efficiency requirements covering energy used by key household services and appliances.
Compliance must be demonstrated as part of the Building Approval process.
