Heating in EU households accounts for 79% of the total energy consumption. In cold climate areas, like Finland, the percentage is even higher. Enermix set out to test how room-level control in district-heated apartment houses would affect the comfort of living and energy consumption.

“Our mission is to digitalize Finnish buildings, especially the existing ones,” says Janne Heinonen, the CEO of Enermix, a Finnish tech company. “We focus on existing buildings because the owners are still reluctant to invest in smart building solutions during construction because of the additional costs they entail. Another reason is that there’s not fierce competition in making old buildings smart.”
