The objectives of this project are to: design, construct, install, monitor and assess a prototype ground-coupled cooling system. o Determine optimum design parameters; establish best practice guidelines for using the technology.

This project aims to demonstrate the use of a ground-coupled cooling system in a London tube station (Victoria). The following steps will be carried out during the project: examine literature and the theoretical basis for ground-coupled cooling technology; look at existing systems to identify the design objectives, component and system performance, parameter measurement, control strategy and relative achievement of system aims; produce a detailed specification of a prototype ground-coupled cooling system, for implementation in a London tube station, including life-cycle and maintenance-cost analysis, and risk assessment; appoint a contractor and install the prototype in conjunction with the London Underground; monitor and test the prototype for a minimum of 12 months; optimise design parameters and establish guidelines for using the technology in conjunction with CIBSE; disseminate the results of the research to leading professionals. The prototype will provide data on the performance of this technology in a new operating environment. The unknowns of particular interest include the extent of influence of an underground cooling system, the ambient temperatures achieved within the passenger environment, the sizing of plant and components, control performance, water availability, quantity and temperature and corrosion. This project aims to provide a platform for exploitation of ground-coupled cooling systems in other markets. The technology developed could be utilised to extract cooling from the current groundwater abstraction, which is pumped to reduce the groundwater level, eliminating the need for energy intensive cooling systems
