Lausen

Lausen

The Lausen site, located near Basel (Switzerland), serves as a major BHE field for small-scale development and validation of the control methodology developed in RECOIN.
The site is, at the very least, unique because of the high-resolution temperature recordings for several years. At the same time, it represents a typical, on-market setup of a small-scale energy system to maximize the utilization of renewable energy from geothermal sources. Since the year 2016, a multi-family building has been supplied with heating via a system of 3 BHEs (depth: 145 m).
In RECOIN, the small BHE field of Lausen will serve as a unique field
lab, test, validation and reference case with full resolution of ground
thermal evolution during the past five years.

Because of the high-resolution monitoring, the propagation of thermal fronts and, subsequently, the BHEs’ performance in the subsurface can be tracked and evaluated in a spatially accurate scale. Monitoring of the BHE system is complemented by recordings of heat pump operation, including heat meters and temperature sensorsm and by, operational boundary conditions.
The present monitoring application is funded by the Swiss Ministry for Energy (Bundesamt für Energie, BFE).
