Blue Eco Homes – Lower Blue Mountains
There is something special about living in the bush, even more special is doing it with the lightest possible footprint. This award-winning Blue Mountains home incorporates passive design and sustainability principles. Evolution Windows selected bushfire compliant, double glazed window and door systems from the Vantage® residential range to help create a beautiful, comfortable, resilient living space.
Smart, sophisticated, unpretentious – introducing what may very well be the future of sustainable housing in Australia. Located in Winmalee, in the Lower Blue Mountains, this single story, timber-framed home has achieved an incredible 7.5-star energy rating and an enviable carbon-neutral status, recognised at the recent Master Builders Association National Awards Night. Balancing green credentials with lifestyle requirements Blue Eco Homes and Ross Young have created a generous and beautiful family space where entertaining and lifestyle play an equally important role.
This project presented several challenges, not least of which was Blue Eco Homes’ absolute commitment to ensuring the house was as self-sufficient as possible with regard to energy and water use and the treatment of waste water. Right from the outset, the technologies required to achieve a carbon-neutral home could not be a mere afterthought. Instead, they had to be well integrated into the construction, and called for extensive collaboration between technology suppliers, the builder, his family and the designer.
Evolution Windows, were invited into the mix early in the process. Glazing was a critical element of this project and the careful selection of window and door systems and glass was necessary to respond to the varied challenges presented by the site.
The home’s proximity to the bush meant it had to be built to strict bushfire-resistant standards. But the builder was adamant he wanted more than a simple protective bunker, and extensive clearing was out of the question. To create a fluid space that connected with its environment, the builder cleverly utilised a fire-resistant concrete base block, corrugated metal and compressed fibrous cement sheet cladding, and non-flammable external materials which are not only low maintenance but retain a sense of warmth which perfectly sympathises with the textures and colours of the outside world.
Evolution Windows chose to use aluminium windows and doors from the Vantage® residential range. Double glazing incorporating toughened glass on the outer layer was combined with stainless steel screening to ensure that the window units offered both strong fire protection and good thermal performance.
The gently-bending axis of the house works in synergy with the contours of the site; bedroom wings radiate from a main core, bold stacking sliding doors are used in the main living areas and children’s bedrooms which open onto a large covered verandah and enjoy panoramic views of untamed countryside.
The home’s west-east orientation enables passive design principles to be maximised. Extensive double glazing is used throughout the home to keep the home warm in winter and cool in summer. Vantage Series 525 Louvres equipped with low-E glass provide cross flow-ventilation even at the height of summer.
Walls, ceiling/roof and floors are fully insulated, hot water is provided by roof-mounted evacuated tube collectors, supplemented by a gas boiler, and a roof-mounted 4.2kW photovoltaic grid interactive system generates all the house’s electricity, with power left over to return to the grid.
The builder has achieved a warm and inviting living space utilising the latest technology in lamps and fittings, and cooking appliances have been chosen for their low energy use. Rainwater is collected in tanks which supply the whole house. Their massive 90,000 litre capacity means the water in these tanks is also available for fighting bushfires.
All waste water from the house is cleaned for use on lawns and gardens, the laundry, toilet flushing and general external use.
The end result is a house that not only looks great but represents a real step forward for sustainable housing. A template for greener living? Watch this space.
Special Note: This home was one of few to survive the devastating 2013 bushfires affecting Springwood and Winmalee, the site is located in the main area affected by the fire.
