In Sweden a new office complex will be heated through the power of body heat. The offices will be attached, or really close, to a major train station that is already heated by the people who use it.

“We had a look at it and thought ‘We might actually be able to use this’,” said Karl Sundholm, project leader at Jernhusen, which also owns the station. “This feels good. Instead of just airing the leftover heat out we try to make use of it.”

Jernhusen markets the building as “environment smart” and aims for its energy consumption to be half of what a corresponding building usually is.

The bodily warmth from the central station will be redirected to heat up water. The investment will be around 200 000 Swedish crowns, Sundholm said.
