10 keys to
environmentally sustainable design

1. Orientation

Getting the orientation and shape of the building right are big steps to being energy-efficient economically. Consider sun shading in summer, warmth from the winter sun, daylight to reduce the need for electric lighting and windows placed to catch cooling breezes.

2. Thermal Mass

Dense materials inside a building help to keep interior temperatures stable and comfortable. This is as important as insulation, even in the moderate Queensland climates.

3. Insulation

Bulk and reflective insulations work together to keep heat in when its needed and out when its not.

4. Low Embodied Energy

Materials should be selected based on the environmental impact and energy required to extract the raw materials, manufacturer the product, transport, install it, maintain it and ultimately dispose of it at the end of its life.

5. Low Toxicity

Low toxicity (low VOC) paints, flooring, cabinetry boards and adhesives used throughout will promote healthy internal air quality and reduced greenhouse gas emissions.

6. Respect for the Natural Environment

Choose renewable materials, sustainably-managed timbers, recycled, recyclable, compostable and low-pollutant materials. Recycle and reuse construction waste.

7. Think Globally, Act Locally

Choose locally-produced materials and tradespeople where possible to reduce transport energy & greenhouse gases, to support the local economy and the local skills base.

8. Energy-efficient Systems

Passive-solar heating, mixed-mode ventilation systems, daylighting, energy-efficient artificial lighting and automated controllers work together to minimise operational energy use.

9. Water Efficiency

Collect rainwater and use it wherever possible. Use water- and energy-saving fixtures throughout.

10. Education

Demonstrating the effectiveness and beauty of eco-friendly design and products is vital to achieving a sustainable future - the more people understand the issues and the possibilities, the better we can all adapt to the changing world.

It is as easy to build 'green' as not to build 'green'. The choice is simply between caring about the future or being short-sighted. It goes to the heart of what it means to be sustainable and is imperative if we are to protect the natural environment and the prospects for future generations.
