The Association of Building Sustainability Assessors (ABSA) is encouraging conveyancers, mortgage lenders, certifiers, property inspectors, real estate agents and building surveyors to use a new investigative tool, ABSA’s Rating Certification System (RCS), which can assist them to find out information about a newly constructed property’s energy rating.

“This is a new and innovative tool developed by ABSA to make the work of people in these important professions just that little easier and thorough – they can quickly ascertain whether the initial design of a new home or unit has been assessed by a quality, accredited ABSA building thermal performance assessor and is capable of meeting mandatory 6 star energy efficiency requirements,” Rodger Hills, ABSA’s CEO said

“Until now, knowing what energy rating the house or unit is capable of achieving has required a lengthy and often fruitless search of Local Government development application records. ABSA’s Homeowner Certificate changes all that.

“The certificate shows the NatHERS Star Rating the building should achieve as well as the simulated/predicted heating and cooling loads (in MJ/m2/annum),” he said.

Homeowner Certificates can only be generated by an ABSA Accredited Energy Assessor (Residential Building Thermal Performance Assessor) who has:

  • Committed to and signed the ABSA Code of Practice.
  • Completed training and an accreditation exam.
  • Passed regular Quality Assurance audits.
  • Current Professional Indemnity insurance cover.
  • Accumulated Continuing Professional Development (CPD) points.
  • Paid all accreditation and membership fees.

If ABSA’s Rating Certification System (RCS) that generates the Homeowner Certificate finds that an assessor does not have all the above points of accreditation, the assessor cannot certify a dwelling.

As a further safeguard, the Homeowner Certificate has a unique check-digit Certification Number that can be verified by entering it on ABSA’s website and validating the rating information. This eliminates any chance of fraud where unscrupulous operators might try to forge or duplicate certificates.

“Consumers have a right to get the energy efficient homes they pay for and the ABSA Homeowner Certificate is key part of the process ensuring that happens,” he said.

“Those who are involved in the vital work of signing off on the quality of a property, or inspecting it for a home buyer are entitled also to have a smooth, transparent and easy system for finding information about the mandatory energy rating of that property,” Mr Hills said.
