BDAV 2017
10-Star Sustainable Design Challenge

The BDAV's 10-Star Sustainable Design Challenge is for conceptual projects that combine admirable architecture with efficient planning solutions and materials utilisation. The Challenge offers the building design fraternity the opportunity to design 10-Star energy efficient homes, and be recognised for their design abilities and expertise in sustainable design responses, as well as positioning BDAV Members as leaders in environmentally sustainable design. The Challenge aims to raise awareness that good design reduces greenhouse emissions and household bills. The BDAV acknowledges that, although 10 Star houses are probably only appropriate for those in the community who are totally committed to 'making a difference', those designers who 'know what it takes' will design cost-effective 6, 7 and 8 Star houses with ease.


Winner: Sustainability House for Paradigm Shift

An affordable, 10-star sustainable home designed for the Adelaide climate by Sustainability House to meet market demand has won the Building Designers Association of Victoria's 2017 10-Star Sustainable Design Challenge.

Paradigm Shift is 'a fundamental change in approach or underlying assumptions'. Sustainability House have envisioned a home which is more than just a 10 star home, encompassing all that makes a home sustainable, resulting in minimal operational costs.

This affordable home has generous proportions, integrates indoor and outdoor living and promotes a healthy living environment through IEQ choices.

Versatility is achieved through minimum 920mm wide doorways for wheelchair access and a flat framed roof structure engineered to support the loads on an additional level, providing adaptabilty for a growing family.

The design demonstrates a considered approach to appropriate use of thermal mass and insulation, and strategic solar penetration. The Australian hardwood timber cladding complements the landscape and the streetscape, while the inside is light and bright with well positioned PVC framed high performance double glazing and light internal finishes.

The home incorporates a 5kW PV array with battery storage removing any reliance on natural gas, and allows for 12000 litres of rain water storage for reuse.

The estimated build cost of under $390,000 demonstrates the affordability of sustainable living in a market that is dominated by continued property cost increases, achieving the designer's Paradigm Shift.

"We believe the inclusion of design at concept facilitates all buildings to achieve this outcome," said Jim Woolcock from Sustainability House.The BDAV's 10-Star Sustainable Design Challenge is for conceptual projects that combine admirable architecture with efficient planning solutions and materials utilisation.

Commendation: Melbourne Design Studios in collaboration with MACLaren Homes for The Courtyard House

A commendation was awarded for The Courtyard House (by Maclaren), an initiative of Maclaren Homes in collaboration with Melbourne Design Studios, which was the result of a real-world client brief for a four-bedroom home to be constructed in a Melbourne suburb. The Courtyard House is a beautiful benchmark for localised sustainable living that suits the Australian way of life. Under construction in 2017, the 10-star Maclaren show house will inspire a wider market to realise that sustainability is not just for 'tree huggers' but, with the right design, it can mean practical and efficient everyday living that benefits everyone.

Melbourne Design Studios have investigated a novel approach of using a steel framing system in their design with the inherent complication of thermal bridging issues. The accommodation solution was reasonably generous incorporating a three-bed family module plus an additional zone with flexible potential for home office, air B&B rental or granny flat.


Finalist: 'Positive Impact House' a collaboration between F2 Design and several entities/individuals, including 'The Sociable Weaver'.

Construction of The Sociable Weaver's Positive Impact Home is anticipated to be completed in May 2017. Once occupied by one very lucky family, the performance will be monitored by Melbourne University. This will be enormously instructive as a feed-back loop to understand how the NatHERS result compares with the lived experience. Energy efficiency was only one part of the brief. Clear objectives have been set for occupation of the land to be carbon positive as defined by an eTool lifecycle analysis. This has been easily achieved with a 5kW PV renewable generation system generating power way in excess of that used within the house. Feng Shui principles have been observed as have environmental sustainability of materials used in terms of supply logistics, end of use recycling and indoor air quality.
