Over 550 people are moving into new ‘eco-homes’ in London rated as ‘excellent’ under Britain’s Code for Sustainable Homes, thanks to a partnership between utility E.ON and housebuilder Barratt. Instead of getting gas from the national grid, residents will be supplied by a district heating network which should reduce carbon emissions by up to 25% and cut heating and hot water bills by up to 23%.
The mixed development in Hackney, East London, is supplied with heat from an on-site energy centre powered by gas-fired CHP units, along with biomass boilers and gas-fired back-up boilers, providing 5 MW of heating and hot water and 185 kW of power.
Each home or business is equipped with a heat meter to measure the amount of heat delivered, rather than the amount of gas used. Equipped with smart technology, the meters are read remotely and residents will receive a monthly bill in the normal way. Residents will receive electricity via the National Grid; however the library and retail units will receive electricity generated in the energy centre by the CHP units.
Under an energy services company agreement, E.ON Sustainable Energy Solutions will manage and operate the decentralized energy centre.
