The Department of Environment and Energy has engaged with the Moreland Energy Foundation, an independent not-for-profit organisation, to undertake a study into how the building industry has responded to the challenge of building dwellings to higher thermal performance standards and the practice of voluntary improvement to thermal performance beyond the regulatory minimum.

This survey assists with the study and we thank you for your time. The survey should take less than 10 minutes to complete.

Question Title

* 1. What is your occupation?

Question Title

* 2. What member organisations are you a member of? Select all that apply.

Question Title

* 3. What state or territory do you predominantly work in?

Question Title

* 4. What residential building typologies do you typically work in?

Question Title

* 5. In the state or territory where you predominantly work, what were the three most common changes to designs or specifications that were initially made to meet the most recent change to the thermal efficiency standard (BCA 2010) ?

Question Title

* 6. In the state or territory where you predominantly work, what further changes (if any) to designs or specifications have been made more recently to optimise designs to meet the current standard? Select up to a maximum of three responses.

Question Title

* 7. Referring to examples you have worked on, what design or specification improvements would typically be used to go well beyond the minimum energy efficiency standard (BCA 2010)?

Question Title

* 8. What was the initial cost impact per dwelling of the most recent change to the energy efficiency standard compared with before the change in the state or territory where you predominantly work? Base answers on the dwelling typology you predominantly work in.

Question Title

* 9. In the years following the most recent change to the energy efficiency standard what was the impact in terms of cost per dwelling of further design and specification changes undertaken to optimise designs against the standard - as compared with the initial cost impact of the regulatory change (BCA 2010)?

Question Title

* 10. In the state or territory where you predominantly work, have the cost of any of the following products changed since the most recent change to the energy efficiency standards for residential dwellings (BCA 2010)?

  Less expensive Neutral More expensive
Double glazing 
Insulation
Solar PV

Question Title

* 11. As part of this engagement we are seeking evidence of design and specification changes and cost impacts of regulatory change and voluntary improvement well beyond the existing standard. If you would be in a position to share construction drawings, energy rating information or cost information please provide your details below.
