Speaker: Duncan Nicholson, Director and UK Network Skills Leader, Ove Arup and Partners Ltd
Thermal (energy) piles were introduced into the UK during Brandl’s Rankine lecture in 2002. This was soon followed with projects such as Keble College and Pallant House. Recent projects have included One New Change, London and current work includes the Crossrail station piles and walls.
The presentation will discuss the development in thermal piles and summarises some of the recent work in the Ground Source Heat Pump Association’s (GSHPA) Thermal Pile and Wall Standard. This standard covers the responsibilities and contractual arrangements for thermal pile design and construction. The development of thermal pile design principles will be summarised and related to the back analysis of pile tests. Details of installation methods and testing will be explained. The longer term monitoring performance of the Keble College thermal piles will be presented and the high coefficient of performance (COP) described. Details of installation methods and testing will be explained. In addition, some of the recent work on thermal walls will be described, including the effects of thermal gradients across walls. The effects of thermal expansion of the wall and soil on the wall moments and prop forces will be presented. The recent development of thermal tunnel linings will be discussed, together with some of the work on the demonstrator tunnel at Crossrail.
Duncan Nicholson is a Director and UK skills network leader at Arup. He has 10 years experience of thermal pile design. He is vice chairman of the GSHPA and worked on the recent borehole ground loop standard. He is chairman of the working party on the standard for Thermal Piles and Walls currently at the final draft stage. He leads the team developing the thermal tunnel lining on Crossrail.
