This sustainable home was developed to showcase innovative concepts and products that have a positive impact on the built environment. The intent for this home was that it would be comfortable for the occupants all year round without costing the earth to run.  The north facing solar passive designed home boasts leading technology in solar water heating, hydronic under floor heating, performance glazing and low water use indigenous landscaping, to name just a few of the key green features.  The initial excavation was minimal with the house having a number of small internal level changes, that also creates defined internal spaces in the open plan northern living area. This dramatically reduced the construction cost and had little environmental impact as a result.  Energy saving features include:  -   1.9kW Photovoltaic system providing electricity from the sun;   gas boosted solar hot water system;    hydronic under-floor heating to all bedrooms and wet areas, heated with 90 evacuated tubes and boosted with a wet back to the wood fire;     LED lighting predominantly throughout the home with fluorescent lighting in the laundry and garage;    ceiling sweep fans in living areas and bedrooms;     induction and gas cooking.      All roof water is collected and stored in a 22,000 litre tank for use in the laundry, toilets, garden and the lap pool.  Low VOC paints have been used along with low embodied energy materials, recycled hardwood bench top in the kitchen and composite decking boards.  The end result is an energy efficient home that is a bright naturally lit home, that is warm in winter, cool in summer, has a low environmental impact, and low running costs.
