New Online Service Promotes Sustainable and Fair Use of Geothermal Energy in Helsinki

The popularity of ground heat has grown steadily in Helsinki over the years, driven by demand for energy-efficient and emission-free heating solutions. As the number of geothermal heating systems increases, concerns have emerged about the effects of borehole fields on the geothermal resources of neighboring properties. In response, the Geological Survey of Finland GTK and the City of Helsinki Urban Environment Division have jointly developed an innovative online service to help designers and companies to assess the thermal effect of borehole fields.
