Taking the specification of ground-source heating and cooling schemes to new heights, by John Findlay, director of Carbon Zero Consulting Full story...Police HQ proves its worth
In 2005, the new Gloucester Police HQ became a renewable-energy pioneer when it used a ground-source heat-pump (GSHP) system for heating and cooling. Not only was it the largest ground-source heating-and-cooling system installed in a UK building to date, but it was also the first to be fitted in a building being built under a Private Finance Initiative. Full story...Geothermal response testing for closed-loop systems
Key parameters in the design of a ground-source heat-pump system are the ground thermal parameters and borehole heat-exchanger construction. These parameters (soil thermal capacity and conductivity, far field temperature, borehole resistance, effects of ground water flow) are difficult to estimate from general soil information. Thermal response tests (TRTs) have been developed to measure these key parameters on an actual field installation. Full story...A true collector’s item

DESPITE the current economic turmoil, the geothermal market remains buoyant and enquiries involving energy piles remain stronger than ever. The growth in energy pile use over the last two years in the UK has been remarkable (figure 1). Full story...Piling on the energy
There were several presentations at the EPFL workshop from industry and academia (see box). J. Wilhelm, of the Swiss Geothermal Energy Promotion Centre, described the astounding increase in the number of geothermal energy systems in Switzerland. The installed length of ground-source heat-pump probes (all types) reached almost 1 million metres in 2009, compared to modest beginnings of 50,000m in 1997 (see figure 1).

Underground production-drilling rigs are divided between those that use top-hammer technology and those that use down-the-hole (DTH), which was previously only used in surface drilling. As DTH use has developed in the underground market, the term in-the-hole (ITH) has been used to describe the underground application specifically, which is largely what is used in this article, though the two are often used interchangeably in the market.
