1. Ground-source heat pumps

Mitsubishi Electric
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.

Grenfell is the building industry's Piper Alpha says CIBSE

The recent passage of the Building Safety Act is a welcome recognition of the fact that making safe buildings is a highly skilled operation says the Chartered Institution of Building Services Engineers, endorsing the need for more effective regulation and a profound change in culture.

Underlying project-starts uptick indicates gradual recovery, Glenigan data suggests

  • 13% rise in detailed planning approvals against the preceding three months
  • 18% decline in main contract awards against the previous year
  • 9% increase in underlying starts during the three months to May

Glenigan has released the June 2022 edition of its Construction Review.
