Case study: Stover Nature Interpretation Centre
Lake system used to heat and cool visitor centre
Built by sailor James Templar in 1765, Stover Country Park is now operated by Devon County Council as a nature reserve focusing on the dragonfly and wildfowl population in this UK ‘Site Of Special Scientific Interest’.
The new Visitor and Interpretation Centre was opened in July 2000, and offers classroom facilities for school groups as well as high quality displays interpreting the wealth of plants and wildlife found in the park.
The visitor centre has been built with sustainability at its heart and as such is heated and cooled by renewable energy from the nearby 10 hectares man made lake, fed through a Kensa ground source heat pump..
A 24kW ground source heat pump passes water through a closed-loop of plastic slinky pipe sunk in the middle of the lake to absorb heat in winter and to reject heat from the building in summer.
Up to three quarters of the heat generated for the installed underfloor heating is free of charge and is renewable. This means as well as low running costs the system has lower CO2 emissions than traditional fossil fuels and no gas/oil tank is required. Also no regular servicing is required as the system has a longer design life than traditional boilers.
