This FOI release from Treasury contains email correspondence from Western Australia's Department of Energy, Mines, Industry Regulation and Safety regarding concerns about manipulation of NatHERS-accredited software tools and performance solutions under the National Construction Code 2019 and proposed 2022 building codes for energy efficiency. The emails, dated July 2024, discuss inappropriate use of performance solution documentation and VURB (Verification Using Reference Building) manipulation in building energy efficiency assessments. Officials indicate the problem was expected to be resolved by 1 May 2025, with building surveyors who continued accepting inappropriate performance solutions potentially facing disciplinary complaints if audited or reported. The correspondence reflects internal coordination on regulatory compliance and enforcement mechanisms relating to building code energy efficiency standards.
