Adelaide's First Energy efficient 10 Star Home
The strategy of the 10 Star Home was to provide inclusive environments to demonstrate how aspects of the building industry can foster a social commitment to an ecologically sustainable future through clever design, and collaborative and resilient relationships. The Nationwide House Energy Rating Scheme (NatHERS), is a performance based rating system that rates the energy efficiency of a home, based on its design. While the minimum compliance for homes in Australia is 6 stars, the design of the 10 Star Home goes above and beyond 10 stars. One of the most significant challenges in this space is helping home builders and buyers to understand the benefits of designing to contribute to a circular economy through durability and adaptability. The 10 Star Home is an opportunity to demonstrate what is possible when contemporary construction materials, techniques, and interdisciplinary interactions. The collaborating partnerships in the industry that contributed to the success of the design have given weight to our objectives to provide a wave of movement towards a sustainable future. With the support of industry professionals, the goal of the 10 Star Home is to be able to provide reiterative feedback of data to governing bodies, associations, industry and community.
Frequently Asked Questions
The 10 Star Home is Located at 41 Glen Stuart Rd in Woodforde, South Australia.
The home will not be available for walk-ins at this stage. Stay tuned on SUHO social media pages or subscribe to our newsletter for exclusive tours and open days.
The home build was undertaken as SUHO has a long standing history of designing and optimising buildings to a high star level. After wining the BDAV 10 Star Challenge one year, they chose to put it into practice and undertake an 'as built' 10 star rating to feedback the information to the regulatory software developers, to improve the standards of building in Australia. CSIRO, the software developer for First Rate, has not had a 10 star home to evaluate also. The home will be monitored to give as-built data which also can then inform the future of the star bands and predicted energy loads on buildings.
Although it may not be in full detail, it should be available on the real estate website once the home goes on for sale.
There wont be anyone living there in the interim while the home is being monitored in the early days. The back end of the ratings program also are able to be manipulated in non-regulation mode to adjust the occupancy patterns so that the comparison can be made. The importance of this is that the current occupancy in the software for compliance, isn't reflected of a 'case-by-case' family, or even indicative of the differences between how one person would operate compared to another.
Utilizing Victoria's leading residential thermal performance assessment software; First Rate 5, SUHO have achieved the maximum rating of 10 through considering thermal comfort, materials, insulation, minimum energy consumption, building orientation, glazing type and shading devices built for the Australian climate without the use of artificial heating/cooling.
The 10 Star house is designed to be air-tight to trap and maintain heating and cooling within the home thus reducing the carbon emissions that may be produced. Receiving a 10 Star rating means that the temperatures within the design will not fluctuate spontaneously, and with the inclusion of solar panels as one of the main energy source and lithium batteries as the storage of energy, the potential for a return of investment will be through the low cost energy bill that will save the owner thousands per year.
The worth of investing in sustainable living will become clear through the lowered cost of living
Artificial thermal conditioning requires energy to generate heat and cooling whilst natural (Passive) is provided through storing heat from sunlight during winter, whereas dispersing energy through ventilation, night flushing, radiative cooling, evaporative cooling and earth coupling for cooling during summer.
Not only does passive heating and cooling lowers the energy consumption and billing cost, it will allow the home to be dependent from large energy providers who produce energy through fossil fuel, which contributes to green house gas.
