This module calculates the potential of shallow geothermal energy to be used in ground source heat pumps for selected regions in the form of a raster file. The inputs are raster files with initial ground temperatures, depth-averaged ground thermal conductivity and depth-averaged ground thermal capacity.
It aims to compute the shallow geothermal potential based on r.green.gshp.theoretical according to the G.pot methodology. In this module, the output is the theoretical maximum energy that can be converted in the ideal case without considering the financial and spatial constraints.
The input parameters and layers, as well as output layers and parameters, are as follows.
Input layers and parameters are:
The advanced input is:
Output layers and parameters are:
A deeper explanation of the default input raster is available in the Hotmaps repository
Users can give different ground characteristics (e.g. ground temperature, ground conductivity and capacity), if available. Users can also define the different characteristics of the geothermal system like the Borehole geometry.
