Here in Australia, for example, in 2019 energy ministers at State and Federal levels established the Trajectory for Low Energy Buildings, which sets out a plan to increase the amount of sustainable housing across the country. As time has passed, and we edge towards that 2050 zero net carbon emissions goal, its importance has grown.ĭesigner, specifiers, and legislators have begun to understand the importance of environmentally friendly houses. Traditionally, across the western world, the sustainable house concept has held little sway. It refers to homes that minimise negative environmental impacts on flora and fauna moderate the use of construction materials, energy, and space and help maximise human wellbeing. In general, however, the term refers to a dwelling that required low to zero energy to build and requires low energy to heat and cool. Because of the complexities around supply chains, products, and design, ‘sustainable homes’ are difficult to define. The answer to this question is not simple. We must embrace the concept of sustainable homes. It is clear, therefore, that if we are to meet our Paris commitments, we need to reduce the carbon we use in our homes. The 2016 Paris Agreement commits signatories to the goal of limiting “global warming to below 2☌, preferably to 1.5☌, compared to pre-industrial levels by 2050.” It states that to achieve this goal, the global community will need to reduce net carbon emissions to zero by at least 2050, and preferably earlier.Īs the Low Carbon Living CRC points out, Australian homes generate around 13 percent of our carbon emissions. And so does the realisation that, by necessity, sustainable housing will have to be an important part of its solution.
