Groundwater Energy Designer
Groundwater Energy Designer (GED) is a tool for planning and dimensioning of thermal groundwater utilization for heating and/or cooling, developed by ÅF and specifically tailored to the needs of our clients. GED provides a fast, light-weight toolset, primarily focused on early project phases at small to medium size installations.
Starting from an assessment of heating or cooling demand, GED may be used to investigate the potential for the direct utilization of groundwater. Based on a simplified representation of hydrogeological conditions, the wellbores for groundwater withdrawal are dimensioned and the options for the infiltration of used water are analyzed with regard to the local situation in terms of available area and natural groundwater flow.
By varying the number and location of wellbores, it is possible to interactively test various configurations and to minimize any undesirable thermal effects on the groundwater, based on actual site conditions.
The GED is available with an interactive user interface in either English, German, or French and is accompanied by comprehensive documentation. A free trial version is available to download. Order forms for permanent licenses are included in the download.
GED was developed with support from the Swiss Federal Office for Energy (BfE) for the dimensioning of facilities engaged in the thermal utilization of groundwater. The program is offered in two packages:
- A basic package including the functionality required for the early project phases of small installations.
- An extension package includes the option of demand stepping per year and provides access to the solver parameters to optimize the program, or to run a batch.
