Making Your Home Sustainable - A Guide to Retrofitting

Sustainable ideas, using natural energies, to improve existing houses in a cool-temperate climate

In 1991, architect and solar consultant Derek Wrigley moved into a townhouse in Canberra and faced a new design challenge - how to retrofit an existing suburban house to use renewable energies rather than fossil fuels. Convinced that building design could do more to achieve sustainability, he developed a series of innovative devices to improve the energy efficiency of the house, and modified the existing design to work harmoniously with the local climate.

The house now generates about 15 per cent more electricity than it consumes, and the photovoltaic system should have a pay-back period of just under nine years. The house ventilates and cools itself without any electrical assistance or air conditioning, and greywater nourishes the garden. Derek has been advised that for every dollar spend on retrofitting, he is adding at least double that amount to the house's market value.

Making Your Home Sustainable is a practical and easy-to-follow guide for homeowners, builders and architects who are concerned about the effects of climate change and environmental degradation, and who want to do something about reversing the trend. Derek Wrigley shows how simple modifications to existing homes can help to reduce emissions of greenhouse gases, and utilise natural rather than imported energies and resources. He clearly explains how to:

Identify retrofitting potential when buying a home;
Rationalise energy and water consumption;
Provide sunshine in southern rooms, warmth in winter, and cool air in summer;
Use ventilation and insulation to reduce the need for artificial heating or cooling;
Install a solar hot-water system;
Utilise wasted sunlight to heat and illuminate your home;
Create a beautiful landscape which also contributes to your household energy efficiency; and
Install reflectors, sunshades, water recycling, heliostats, double-glazing, photovoltaics, water tanks, and other energy-saving and water-saving devices.

About the Author

Derek Wrigley studied architecture and town planning at Manchester University. In 1948 he emigrated to Australia and lectured at NSW University of Technology, where he established the first building-science course in Australia. In addition to teaching, he has practised as an architect, industrial designer, and solar consultant - including designing and building six solar houses. He was a co-founder of the Industrial Design Council of Australia and was awarded Life Fellowship of the Design Institute of Australia in 1980.
