Green Smart Magazine : GreenSmart 2010
In 2010 a number of states will increase the existing requirements for energy efficiency in new homes. Where changes occur, they will also apply to renovations to existing homes. Water efficiency on the other hand, seems to be settled for now and there are no changes planned. Changes to energy efficiency rules The national Building Code of Australia (BCA) has required new homes and apartments to meet a minimum five-star energy efficiency rating since 2006. In 2009 the federal government agreed to increase this minimum to six stars in 2010, but to allow the states to adopt the change anytime up to 2011. Every state and territory has its own rules and regulations setting out the minimum requirements to build a new house or renovate an existing home. In many cases, these rules are a combination of planning laws (state government and local council), and building laws, which are generally contained in the BCA. In 2010 the ACT, South Australia and Queensland will adopt six stars. The ACT adopted the change on 1 May 2010 and is providing an eight-month phase- in period to cater for houses and apartments already in the approval process but where building work hasn't started. Queensland also adopted the change on 1 May 2010 but has included three additional options for homeowners to choose the best way to reach six stars. A home can either have a six-star energy rating, or: • have a 5.5-star energy rating and then include an outdoor living area which is under the roofline of the house and with insulation in the roof; or • have a five-star energy rating and include the outdoor living area (as above) and install a ceiling fan in that living area; or • have a five-star energy rating and install a 1- or 1.5-kilowatt photovoltaic system. South Australia will adopt six stars from 1 September 2010. Changes to the rules for building new homes and renovations are all about energy efficiency. seeing starsStory > Kristin Tomkins rules+regulations from BASIX to BCA 72 greensmart 2010
