Project Manager Pål Solberg
3 generations of heat sources in one and the same technical room

Pål takes us through the heat source history of Ernex AS and shows that even if the company is located in an older building, it doesn't mean that the building cannot be as energy efficient as newer buildings. On the contrary - older buildings are a perfect starting point to begin the work towards energy optimization.

Annual Energy Savings

"50% reduction in energy consumption may sound like a lot, but that's actually what we're achieving together with SASTECH. The initial energy report formed the basis for an optimal process."

Sebastian Geverek
CEO, Enter Kompetanse

"When the heat pumps were up and running, the building's energy use halved and SASTECH achieved a 112 tonne yearly CO2 reduction. The industrial complex spent about 10 million NOK in total on the energy measures, whereas 4.1 million came through the ENOVA grant."

Øystein Ellefsrød
Owner, Andebu Næringspark
