Technical paper: Energy piles for Pallant House, Chicester, UK

Tony Suckling and Robert Cannon, Cementation Foundations Skanska. This paper was first published in GE’s July 2004 edition.


This paper presents a case study of a piling contract undertaken in Chichester in 2003. Unusually, the piles contained a network of plastic pipes, which were subsequently connected to the heating and cooling system for the new building.

The plastic pipes cast in the piles facilitate the transfer and storage of geothermal energy between the structure and the underlying ground mass, allowing the building to be both heated in winter and cooled in summer economically and in an environmentally friendly way.

The philosophy of the geothermal pile technology is presented, together with the modified pile construction techniques used on the site.
