User Guide : BGS Thermal Properties V1 (Great Britain)

The British Geological Survey (BGS) Thermal Properties dataset is derived from a programme of work commissioned in 2004 by the Carbon Trust to assess the suitability of BGS geological records for site characterisation when installing ground source heat pumps (GSHP). The dataset portrays a range of information relating to the thermal characteristics of bedrock – defined here by the 1:250 000 scale digital geological map (BGS DiGMap Geology 250 V4). The information is presented as a vector polygon coverage for the extent of Great Britain (GB). Each record in the dataset describes the lithology, age, Thermal Conductivity, Thermal Diffusivity, Specific Heat Capacity and Density of the rock units. The information is summarised from a wider programme of work that has been developed since the late 1970’s and includes published information from laboratory measurements and deep-drilling observations. The information provided in this User Guide is intended to provide a quick start guide to using and understanding the BGS Thermal Properties dataset V1 (Great Britain).
