The Association of Building Sustainability Assessors (ABSA) is a not-for-profit national membership organisation whose core business is to accredit, certify and conduct training for residential building sustainability assessors.
Introduced by the NSW Government, BASIX, the Building Sustainability Index, ensures homes are designed to use less potable water and be responsible for fewer greenhouse gas emissions by setting energy and water reduction targets for house and units. BASIX is one of the most robust sustainable planning measures in Australia, delivering equitable and effective water and greenhouse gas reductions across NSW.
