Astra Zeneca, R&D Headquarters – Cambridge
ENERCRET have delivered a full geothermal system for the facility, providing renewable heating and cooling energy from a heat pump-based solution. At the time of installation, the ground source solution was largest in Europe to our knowledge. However, this has now been topped by our colleagues in Austria who are currently delivering a mega project at Frankfurt Airport.
The geothermal installation supplies heating and cooling energy to the facility from high quality German engineered heat pumps supporting the base load. Conventional boilers and chillers support demand peaks but a sophisticated control system, designed and delivered by ENERCRET, minimising their use by maximising heat pump operation to charge thermal buffer vessels.
ENERCRET were involved in the detailed design and installation of the scheme, with commissioning due to take place later in the year. We are currently negotiating a long-term maintenance contract and three-year soft landings programme with the client.
The project has been designed to maximise returns from the Governments Renewable Heat Incentive scheme which provides payments for heat energy generated from approved energy sources. Astra Zeneca plan to utilise the money received from the RHI scheme to invest in further sustainable initiatives. ENERCRET have been appointed by the client to manage the RHI application process to maximise payments from the scheme.
ENERCRET’s turnkey energy centre design will provide circa 2MW of heating and cooling energy simultaneously, with any excess generated stored within the borehole field for use in the opposing season. The borehole field consists of 170 bores, each drilled to a depth of 170m.
