Our Energy Foundations Solutions

Energy foundations, (or ‘Energy Piles’) are a specific type of geothermal heat exchange where geothermal loops are installed into foundations as part of the foundation contractor’s works. This means it is done without adding either significant costs or additional time onto a construction schedule. The thermal load of the foundation can therefore be accessed when heating or cooling is required. Similar principles can be applied to installing loops within tunnels and basement walls.

We pioneered this hugely cost-effective way of introducing low-carbon geothermal heating and cooling into our clients’ buildings with our UK company in the early 2000s and have been involved with almost 60 projects worldwide, including some of the largest geothermal projects in the world.


Heat exchange for foundations is generally in the range of between 50 and 100 W/m (29-58 BTU/h•ft•°F). For walls and tunnels, heat exchange is generally in the range of 0.0009- 0.004 Btu/ sq. ft.².

The additional benefits of energy pile solutions are:
• No additional area is required for drilling boreholes or horizontal loops
• Critical path on building program is unaffected
• The building protects the loops from damage by external activities
• Using energy piles ensures area surrounding the site is not sterilized for future expansion
