1. Ground-source heat pumps

14 January, 2009

A ground-source heat-pump system at Mitsubishi Electric’s headquarters at Hatfield is linked to closed-loop coils laid in trenches to extract energy from the ground and help the system perform over 300% more efficiently than a traditional chiller/boiler combination.

The ground-source heat pump, used either in borehole or slinky installations, is a long-established technology in many areas of northern Europe. As targets for reducing carbon loom ever closer and energy prices continue to rise in the UK, the technology is becoming increasingly attractive. Heat pumps extract energy from the Sunlight that heats up the Earth. They convert this low-grade heat into high-grade heat. Even taking into account energy losses from electricity transmission, ground-source heat pumps offer impressive efficiencies. Most ground-source heat pumps have a coefficient of performance of around four.

BCIA welcomes tougher commercial building energy standards but calls for greater ambition across the wider sector

The Building Controls Industry Association (BCIA) has welcomed the government’s confirmation that privately rented non-domestic buildings over 1,000 square metres in England and Wales will be expected to achieve a minimum EPC B rating by 2031, describing the move as an important step forward in improving the energy performance of the UK’s commercial building stock.
