Climate change informationInformation about Australia's past, current and future climate helps industries, governments and communities plan for and adapt to a variable and changing climate. |
The chalengeChanges to the climate system have occurred and are likely to continue. The international scientific community accepts that increases in greenhouse gases due to human activity have been the dominant cause of observed global warming since the mid-20th century. Continued emissions of greenhouse gases will cause further warming and changes in all components of the climate system. Australia's changing climate represents a significant challenge to individuals, communities, governments, businesses, industry and the environment. Australia has already experienced increases in average temperatures over the past 60 years, with more frequent hot weather, fewer cold days, shifting rainfall patterns and rising sea levels. More of the same is expected in the future. |

Our responseThe most comprehensive climate projections for Australia We worked with the Australian Bureau of Meteorology to produce the most comprehensive set of climate change projections for Australia ever released. Map of the eight regions or 'clusters' for which climate change information has been assessed The projections are presented for eight distinct regions of Australia, each of which will be affected differently by climate change. The projections are based on data from up to 40 global climate models, developed by institutions around the world, that were driven by four greenhouse gas and aerosol emissions scenarios. Results have been prepared for 21 climate variables (both on the land and in the ocean) and for four 20-year time periods (centred on 2030, 2050, 2070 and 2090). |

Large boarding housesWe have a new streamlined process for completing a BASIX assessment of a large boarding house. |

We have a new streamlined process for completing a BASIX assessment of a large boarding house, (which includes student accommodation) provided it meets all the criteria below:
It is called the Large boarding house thermal comfort method. It is similar to a standard BASIX assessment, except for the following differences:
So long as the project meets all the eligibility criteria listed above, the Tool will automatically enter values for heating and cooling loads equivalent to the heating and cooling caps in the climate zone of the project. That is, you do not have assess the thermal comfort of the project as part of the BASIX assessment. Instead, the thermal comfort must be assessed at a later stage (i.e. the construction certificate stage) against the Section J requirements of the National Construction Code (NCC) - Volume 1. The BASIX Certificate will contain an additional commitment requiring an assessment against the Section J requirements of the NCC - Volume 1 prior to obtaining a construction certificate. You must complete all other sections of the BASIX assessment, including passing the Energy and Water sections. Please also note that the BASIX certificate will not show the heating load and cooling load values because a thermal comfort assessment has not been completed. |
Why is there a different process for large boarding houses?There is a different process because NatHERS accredited software is unsuitable to model the thermal comfort of individual boarding house rooms. |
What if my project meets some but not all of the eligibility criteria?If the boarding house meets the first eligibility criteria, but does not meet the second or third criteria, you should apply for an alternative assessment as a large boarding house. This may be where the project:
If the development is a small boarding house (i.e. designed to accommodate 12 people or less, and has a total floor area of 300m2 or less), you should complete a BASIX assessment using the single dwelling tool and assess the thermal comfort of the building as a whole |
