This report systematically presents a framework for which benefits and costs of a low carbon housing policy are perceived by the State Government investor. The research findings extend global knowledge of the value of low carbon living to the Government investor, particularly by incorporating industry learning factors, applying actual energy use evidence inclusive of rebound impacts, and including peak demand network benefits. The report finds clear evidence there are multiple benefits associated with a low carbon living housing policy of mandating net zero energy homes. The Government investor would expect to achieve multiple policy outcomes across areas as diverse as health and wellbeing, productivity, energy, as well as the public budget. From a macro-economic perspective, although many impacts were not able to be monetised with sufficient confidence, the Government investor will experience a net increase in local employment, downward pressure on energy prices, and increased economic activity within a more efficient economy better able to respond to world energy price increases. The empirical evidence demonstrates that low carbon living will provide many benefits including improved energy efficiency, energy network infrastructure savings, improved human health and wellbeing, carbon emission reductions, and benefits from increased social capital. The benefits far outweigh the costs associated with creating low carbon housing. Read a media release about this report.
In response to feedback, high-income households can reduce their energy use to a larger degree than low-income households (17% vs 3% reduction). This and other insights were gained by two rapid reviews into research, both Australian and International, on digital services and...Read more
Rapid global urbanization and the increase of the Urban Heat Island (UHI) effect make urban cooling a necessity as well as an opportunity to increase the liveability and amenity of cities. This review is a scoping study of the relevant worldwide UHI mitigation/adaptation...Read more
A rapid review on green-rated office buildings, and their operational energy use, found that the conclusions of six studies ranged from the certified buildings performing worse, similarly or much better than the non-certified buildings in terms of energy usage intensity. Two...Read more
This report outlines the key outcomes of research project RP1037u1 ‘Above-Roof Temperature Impacts on Heating Penalties of Large Cool Roofs in Australian Climates’, an extension to project RP1037 ‘Driving increased utilisation of cool roofs on large-footprint buildings’. The research has been focused on two key aspects of roof thermal performance that had, up until the time of writing, not been taken into account in most investigations into cool roof technology:
Regulations governing the energy efficiency of new buildings have become a cornerstone of US environmental policy. California enacted the first such codes in 1978 and has tightened them every few years since. I evaluate the resulting energy savings three ways: comparing energy used by houses constructed under different standards, controlling for building and occupant characteristics; examining how energy use varies with outdoor temperatures; and comparing energy used by houses of different vintages in California to that same difference in other states.
