The project - 21st-century Living - is designed to discover how consumers use energy, recycling, waste and water, and to look at the practical lifestyle changes they could make, such as low-energy light bulbs or installing a water butt.
During the study, 100 volunteer families' homes will be assessed and audited for their carbon footprint and sustainability levels. A start-up pack with advice will be supported by a website offering practical tips.
The volunteers will also receive £500 from Homebase to spend on ecologically sound home products.
The results of the study will help Homebase develop new eco-products and the knowledge gained will be shared with industry, government, academia and consumers.
