Abstract
The National Strategy on Energy Efficiency(NSEE) is designed to substantially improve minimum standards for energy efficiency in both residential and commercial buildings and accelerate the introduction of new technologies through improving regulatory processes and addressing barriers to the uptake of new energy-efficient products. This paper provides critical analysis of a national response to public discussion papers around the framework with a focus on residential class buildings. The core analysis covers in excess of 85 responses across a breadth of housing industry stakeholders published by the Senior Officials group on Energy Efficiency in 2010. Observations on housing energy performance issues together with technical and evidenced based housing energy efficiency data provide a common theme to the discussions in the paper under the headings of; The house energy rating schemes, metrics and tools, assessors, governance, training and accreditation issues. ? Overall sustainability, incorporating embodied energy, lifecycle of materials, water use and waste treatment. Accounting for climate variation, climate data and future climate change scenarios Economic evaluation, existing housing stock, consumer behaviour, appliance use, etc. The analysis reveals a general support for the Building code of Australia (BCA) as the principle mechanism for implementation though with debate and disagreement on the various software tools and ratings systems currently in use. Also a recognition by stakeholders that the final outcome of the Framework may be that ratings and standards have broader coverage than just energy efficiency, particularly greenhouse gas emissions and that this deserves support not just because greenhouse gas emissions are connected to energy use (and other causes), but because climate change is a key issue of concern internationally and Australia must play its part in reducing its emissions.
