Drilling to harness heat from within the earth is almost completed at the flagship Landscape Gallery in St. Davids. Contractors have sunk more than a dozen 100- metre deep shafts to tap into the natural energy source. Pumps will circulate a mixture of water and anti- freeze to absorb heat from the rocks below ground. This warmth will be piped into the building to power an underfloor heating system throughout the gallery. Pembrokeshire Coast National Park Authority projects officer Phil Roach commented: "Using ground source heat pumps is just one example of the cutting edge sustainable technology and materials being used in the gallery. It will feature solar panels, and rainwater will also be collected and used." The National Park Authority and Amgueddfa Cymru-National Museum of Wales are lead partners in the project, which has been part-funded by the European Union's Objective 1 Programme, the Welsh Assembly Government and Invest Wales (formerly Wales Tourist Board). The Landscape Gallery will cost over £3 million, and is being built by Pembrokeshire contractors, Carreg Construction, of Croesgoch, using a local workforce. It is due to open in the summer of 2008.
