Energy Efficiency
There are two common methods of energy efficiency assessment:
  • BCA "Deemeed to Satisfy" or DTS Compliance Report ( Checklist and BCA Glazing Calculator ) also known as "BCA Energy and Water Efficiency Verfication"
  • Energy Efficiency Star Rating (Software Generated)

In most cases, the less complex and cheaper Deemed to Satisfy or DTS report is sufficient for council approval.  The DTS report is our standard method of assessment by our accredited energy efficiency assessor.  Depending on our schedule, we may also provide you with a Star Rating on request.  The Software we currently use is FirstRate.

Energy Efficiency Checklist

You will find a link below to the energy efficiency checklists and glazing calculators for each climate zone currently available from the Building Commission.  By viewing the documents you can get an idea of the information required to complete your energy efficiency assessment.  Our own Energy Efficiency checklist differs slightly in format, but includes the same information. 


We have compiled a list of the most frequently asked questions relating to energy efficiency assessment.  If you can't find the answer to your question here please don't hesitate to contact us.
