Abstract Summary
A city-scale subsurface thermal characterisation methodology is showcased, in which subsurface archetypes - sets of features that represent a common thermal behaviour - are identified, using the city of Cambridge as a case study. The geothermal potential for the area is estimated in terms of: (a) the amount of power a typical 100 m geothermal borehole can provide - resulting in between 2.3 and 2.6 kW of heating, (b) the percentage of the residential demand that can be fulfilled by deploying boreholes in all spaces available - resulting in an average of 80%.
