Body heat used to warm buildings
by admin
A company in Sweden is using the body heat generated by people passing through Stockholm Central Station to warm an opposite office block. A real estate firm, Jernhusen, decided to harness the usually wasted natural resource that everybody produces.
Speaking about the new system he created, Klas Johnasson, head of Jernhusen’s environmental division, said they are simply using an old technology in a novel way. He added that the difference is only that the energy is being shifted to another building.
Around 250,000 people pass through the capital city’s Central Station every day, generating heat as they go. Buying food, newspapers and books also helps to create more warmth that is captured by the station’s ventilation system.
This warmth is then converted into energy and pumped into an office block across the road and used to heat its water. The system has apparently significantly reduced the building’s carbon footprint and also cut down on energy costs by 25 percent.
All such energy would be wasted if it were allowed to be ventilated away, according to Mr Johnasson. He said the invention is good for business as by saving money on energy, the building becomes worth more. Mr Johnasson added that he is surprised nobody has done it before as it arrangement saves so much money and is also good for the environment.
