Ener-G green technologies will reduce hospital’s carbon emissions
The extensive use of renewable energy and CHP will reduce carbon emissions by 15 t a year and energy bills by £8700 for the new 24-bed Malvern Community Hospital, making it one of the greenest hospitals in the country. The hospital will utilise renewable geothermal energy for heating, cooling and hot water. It will also generate electricity using a CHP unit.
Both technologies will work together to improve energy efficiency. They are being supplied by Ener-G as part of the eco-friendly design brief set by Interserve. Capita Symonds is providing building-services engineering and BREEAM consultancy.
This new hospital will include inpatient and outpatient facilities, X-ray and ultra-sound, day rehabilitation and therapies, palliative care and visiting mammography and MRI scanners. A minor injuries unit will transfer from the existing hospital, offering increased capacity.
The ground-source system involves 25 boreholes and two heat pumps with a combined heating/cooling capacity of 125 kW. The CHP unit has a reciprocating gas engine with an electrical output of 33 kW and a useful thermal output of 55 kW for the building and the ground loop for the heat pump.
