FAQ

When improving building energy efficiency, insulation measures have the highest priority. No other measure can save as much energy for heating.

Several studies demonstrate that the production of insulation materials consumes much less energy than is saved later. Even with 30-centimetre thick insulation materials, such as polystyrene, the production energy required is already amortised after about three years.

No. Boreholes drilled for surface geothermal energy cannot under any circumstances trigger an earthquake. Nor has a geothermal probe ever been observed to have been damaged by an earthquake.

Under the new rules for the installation of geothermal probes, damage can be practically excluded if the rules are carefully observed.
