A FEW BASIC TRUTHS: As a result of neglecting to consider the environmental consequences of our actions, we now find many serious environmental problems emerging. • WE NEED A CLEAN ENVIRONMENT FOR OUR SURVIVAL • EVERYTHING IS INTERDEPENDENT AND INTERRELATED Traditionally, decisions and designs have been based on economics, form and function. The broader environmental context – in which all things exist, and on which all things rely- has not adequately been considered. atmosphere soil ‘resources’ sunlight technology knowledge oceans the built environment forests we are part of the environment, and not separate from it society water culture institutions + structures biodiversity the universe If we want to have ecological resources to use in the future, and ensure a high quality of life, we must start considering the broader environmental context in our designs and choices. the natural environment Teacher Resource: The Sustainable Living Project, UNSW
In most cases, it is not our ‘needs’ relating to the built environment that cause environmental problems – rather it is the way we choose to meet them.

what are the impacts of unsustainable design & building practices ? INCREASED AIR POLLUTION chemicals and gases PRODUCTION OF WASTE rubbish, materials, chemicals, etc UNNECESSARYD ELEPLETION OF NATURAL RESOURCES forests, water, minerals, soil EFFECTS ON PUBLIC HEALTH we all need clean air and water, good food GREENHOUSE GAS EMISSIONS global warming and climate change INCREASED WATER POLLUTION raw sewage rubbish chemicals sustainable architecture looks to find new ways to provide our needs without creating these impacts INCREASED SOIL CONTAMINATION chemicals, dirty water, loss of nutrients Teacher Resource: The Sustainable Living Project, UNSW

ecologically sustainable development: accommodating the needs of the present without compromising the ability of future generations to meet their own needs (Brundtland Report, World Commission on Environment and Development 1987) appropriate technology: making and using technology that meets human needs while taking into account long and short term consequences for society and the environment sustainable design process: 1. understand the needs of the users of the building 2. look at the capacity of the site and the environment in supporting those needs 3. make design decisions and use appropriate technologies to fulfil the above Teacher Resource: The Sustainable Living Project, UNSW

Natural gas • used for the majority of the resort’s energy requirements • causes less pollution and greenhouse gases than coal-fired electricity production • less damage on site, no powerlines or cables needed to bring electricity onto the site ENERGY MANAGEMENT CONTROL SYSTEMS • used to integrate, monitor and control the different sources of energy in the resort • power used in the resort is two thirds of that used by most resorts of the same size Landscaping and revegetation • any damaged areas of the site revegetated • plant types used were sourced from around the site, to minimise the effect on ecological systems Solar hot water panels Wind turbine • produces up to 12% of the resort’s energy requirements • used to supplement the main energy source - natural gas Couran Cove Resort, South Stradbroke Island • used for heating water for use in buildings • additional heat used to heat up the swimming pool • solar hot water heating creates no pollution or greenhouse gases Images: Forest and Wood Products Research and Development Association, 1998 Teacher Resource: The Sustainable Living Project, UNSW
