The Department of the Environment works with builders whose new homes achieve Sap ratings of 80 or more. The list of housebuilders includes: Admiral Homes, Chestnut Homes, Dibben Homes, Mylcrist Builders, Potton and Linden Homes. Others using high Sap/NHER ratings include Beazer Homes, Hamilton Knight and Bellway Homes. A low-energy demonstration house is currently being built alongside the Create Environment Centre in Bristol (0117 925 0505). The Eco House has a Sap energy rating of 100. When it is open to the public in the summer, the geometric structure will house a caretaker-cum-tenant.
Wates claims to be the first UK housebuilder to provide a water-saving Pressure Butt. The system, featured at Wates' Rivermead development in East Molesey (prices: pounds 225,000 - pounds 305,000), recycles up to 35 per cent of the waste water and makes an estimated saving of 14 gallons a day. For further information on the Pressure Butt, telephone 01797 320140. Houses at Hassall Homes' Knightswood estate in Nottingham feature an intelligent TotalHome electronic system which controls heating, lighting and a security alarm.
