Eliminating heating gas
A few years ago, we decided not to use heating gas in any of our new construction projects. Since then, we have preferred to use geothermal energy. In inner-city construction projects, the building site may not offer enough space for the required geothermal probes. In these cases, we fall back on tried and tested district heating and combine it with solar thermal energy in the form of photovoltaic or solar panels on the roofs.
