• Siilinjärvi Hamula school ESCO-contract

Siilinjärvi municipality, Finland

Siilinjärvi municipality signed a contract with Caverion covering the improvement of the energy-efficiency of nine facilities as an ESCO energy-saving project. The ESCO service guarantees that savings are achieved, and the project is funded with the savings generated during the contract period.

"We have signed an Energy Performance Contract with Caverion and our target is to generate significant savings in the energy costs of our facilities. It’s very important for us that we can fund the energy saving project with the savings in energy costs instead of direct budget funding. In addition, with Caverion we can work with only one partner from planning to execution – a partner who can guarantee our energy savings. We are pleased with our cooperation with Caverion, as we have managed to exceed our energy saving targets. That is why we’ve included new facilities in the contract.” - Jukka Kellokumpu, Facility Manager, Siilinjärvi municipality
