Lepido triples energy recovery in newly constructed restaurant

None of the previous attempts to cash in on the energy found in Scandinavian Burger King restaurants have been successful from an economic or technical perspective. Thanks to Lepido, recovered energy from Burger King Östersund is now redistributed to power ventilation and heating (tap water, floors and air) recovering a yearly total of 120 000 kWh.
