30 voices on 2030: the future of energy

The energy landscape is undergoing unprecedented change. To explore what the energy landscape could look like, KPMG asked 30 people to place themselves in 2030 and look back over the last ten years. The 'voices' in this report cover every facet of the energy industry...
Policy report

Decarbonising heating at home

This report examines two major policies targeting renewable heat and energy performance in buildings in the UK from the past decade – the Renewable Heat Incentive (RHI) in Great Britain, and the minimum energy efficiency standard (MEES) in private rented housing in England. It also...
Systematic review

What are the effects of residential building energy performance disclosure policies on property values?

A rapid systematic review of international academic literature suggests that home buyers typically value a more energy efficient home, and when presented with easily accessible information in the form of an energy performance rating, are willing to pay more to live in one.

Maximising your investment: using rating tools to attract sustainable finance for real estate

Sustainable finance has been an area of interest to the National Australian Built Environment Rating System (NABERS) for some time. NABERS have been closely monitoring green bond issuances in the property sector and are encouraged by the uptake of sustainable finance solutions many customers are...

Australia's still building 4 in every 5 new houses to no more than the minimum energy standard

This article discusses house energy regulations and argues that the rate of houses built to a minimum standard is a negligible proportion to an optimal performance standard. The standards should be reviewed regularly to ensure optimal economic and environmental outcomes.

Informing the next generation residential energy assessment tools

The Nationwide House Energy Rating Scheme, commonly known as NatHERS, which is applied through software tools such as AccuRate Sustainability, has become the predominant pathway for complying with energy efficiency requirements within the National Construction Code of Australia. Current energy efficiency regulations have remained unchanged...

Investigating equivalence in compliance pathways to Australian housing energy efficiency

Current regulatory pathways to compliance in energy efficiency for Australian housing are via provisions in the National Construction Code (NCC). This paper first identifies performance evaluation criteria set out in the code presented as a comparative analysis across the different methods of achieving compliance. Jurisdictional...

We need a comprehensive housing approach to deal with heatwaves

Heatwaves across much of the country this summer have revealed a serious problem with our national housing stock. Wendy Miller looks at smarter design and construction, better rating systems and the role of government and industry to overcoming barriers to better housing design.

Overheating risk in the Australian nationwide house energy rating scheme: A case study of Adelaide

Heatwaves are Australia’s most deadly natural hazard and the principle driver of peak electricity demand in South Australia. The disproportionately high peak demand increases electricity prices, causes occasional blackouts and exacerbates energy poverty, all of which limit the use of air-conditioning. Meanwhile, the desire for...

The EnergyFit Homes Initiative Working Paper 6: Australian Information Systems for Household Energy Efficiency

This project seeks to develop a pathway for enhancing the market for low carbon homes at sale and lease. It will combine research and analysis of existing literature, benchmarking of existing information systems, consumer tradesperson research and industry consultation.

Hybrid buildings: pathways for greenhouse gas mitigation in the housing sector

This report demonstrates the pathways that current 5-star rated ‘project’ homes (with average emissions of 9.5 tonnes CO2-e per year) can take to achieve zero-carbon status, with savings in CO2-e emissions averaging eleven tonnes per dwelling per year. The report also identifies key transitions in...

Green offices and recalcitrant tenants: exploring rating tools sensitivities for multi-story office buildings

Ratings tools have emerged to help classify the 'greenness' of a building. These ratings tools assess the energy use or environmental impact of the building and the rating is then used to communicate the building's predicted environmental performance to target owners and tenants. This paper...
