There has never been a better time for public money to go into improving the performance of Australian housing. We could have cut household bills and emissions, as well as saving construction jobs.
A long-term housing stimulus package that focuses on retrofitting to cut energy demand would also help households repay the debts being accumulated during this crisis.
Net zero energy buildings produce at least as much energy as they use. Designing whole net zero campuses and communities takes the energy and climate benefits to a higher level.
Self-sufficiency, outdoor space and a home office will likely be high up the list in future.
Builders compete for customers by touting the features of their homes. Some builders promote 'six-star' home energy ratings in ways that could mislead consumers and breach Australian Consumer Law.
Efficient technologies can save Indonesians not only billions of rupiah but also avoid the need to built 50 power plants by 2030.
Larger homes with fewer occupants have a bigger energy and heating demand.
Finding out what would motivate people to reduce their carbon emissions can be determined by examining behaviour.
Buyers pay more for a home they know has a good energy rating. That's worth an extra 2.4-9.4% in the only part of Australia where energy ratings must be disclosed at the time of sale.
Often presented as one of the best ways to save energy, eco-efficiency often proves to be less effective than one might think.
Making better use of existing building space is a neglected but essential way to cut our carbon emissions. The key is human behaviour. Good low-carbon citizens will help create good low-carbon cities.
The United Nations is calling on world governments to step up action against climate change. Can China, the world's biggest carbon emitter, fulfill its pledges?
The research has been done. The evidence is in. We know how to create cities that are sustainable, liveable and affordable. But we have yet to apply that knowledge widely across Australian cities.
Australia requires a minimum six-star energy rating for new housing. New homes average just 6.2 stars, so builders are doing the bare minimum to comply, even as the costs of this approach are rising.
Fires and building failures highlighted serious gaps in Australian building regulations. But recent revisions and recommendations still fall short of preparing our buildings for climate change.
Rail advocates often make the case that trains are a cleaner mode of transportation, but why is that so? And what would it take to expand rail in the U.S.?
Unless it sparks joy, go ahead and scratch this task off your spring-cleaning checklist.
It's often more effective, cheaper and less controversial than other efforts to confront climate change.
People who use an appliance a lot save more from an energy efficient model. With the right app, they could easily get a sense of their own potential savings when they shop.
In the wake of the Paris Climate Agreement, France has committed to cutting achieving carbon neutrality for its building stock by 2050. While the goal is ambitious, the challenges are significant.
