Henry Boot Construction’s renewables division, Tropo, is helping a council to build its greenest school.

The Dronfield-based firm is installing a ground source heat pump and solar cells which will ensure that the Scunthorpe school will generate more than 50 per cent of the energy it consumes.

More than 300 solar cells are being installed to provide the power needed by the ground source heat pump, which works like a refrigerator in reverse, making use of the temperature difference between liquid flowing through buried pipes and air temperature to heat radiators and warm air systems, in addition to providing hot water.

The solar cells are expected to generate 53.2MWh a year, but only 42.3MWh is needed to run the heat pumps, so the school will be able to sell a further 11MWh to the grid and save £3,000.
