Claims of Departmental support for alternative solution
The Department of Planning, Transport and Infrastructure has been advised of claims that it supports an alternative solution to the 6-star energy efficiency requirements, which permits the use of a 5-star rating for the building fabric and offsetting the star rating difference with solar panels. This is incorrect.
A similar concession has been provided in clearly prescribed circumstances in South Australia - this concession was based on affordability criteria.
The fabric of the building has a distinct and separate Performance Requirement 2.6.1, which relates to thermal comfort for the occupants, to that of the services (P2.6.2) which address the use of on-site renewable energy sources.
Consideration should be given to the ABCB Information Handbook Using onsite renewable and reclaimed energy sources which clarifies the need to deal with the two Performance Requirements separately.
