A low-energy house ‘kit’ has been developed to enable SME builders to deliver zero energy houses at low cost. A prototype has been unveiled of the ‘Zero Bills’ home which sets out to make energy bills for the homeowner obsolete.
It will be sold as a kit of essential parts. Its clever design minimises energy requirements anfd the very low energy needs of the household are met by a roof-integrated PV and energy storage system which can also generate enough power to service a small electric vehicle.
The kits comprises a steel frame and timber wall panels is assembled while roof-mounted solar panels and a pump that recovers stale air through mechanical ventilations to be used as heat, are embedded into the house.
The home is heated by a small air source heat pump that recycles heat recovered from stale air that’s been processed by a mechanical ventilation heat recovery system.
The project developers, ZEDfactory, estimate that housing will cost just £1350 per square meter and be quick and easy to build with.
ZEDfactory are the architects of BedZED, the UK’s first and largest Zero Energy Development. The mixed-use development was awarded the RIBA Sustainability Award 2003 and shortlisted for the Stirling Prize 2003. The company also works closely with leading UK academics and consultants to model predicted energy consumption and production, fluid dynamics and whole life cycle carbon costs of their designs to ensure they achieve the lowest environmental impact possible.
