GeoAlto stands for sustainable heat and cold from the earth. Near-surface geothermal energy is a central component of the heat transition and is available year-round at almost every location as an energy source for heating and cooling buildings. Geothermal energy is also increasingly being used as “cold local heating” for the decentralized supply of entire districts or groups of buildings. With our expertise, we ensure the successful use of geothermal energy for an environmentally friendly and comfortable indoor climate of the future.
