# Hot Swedish Bodies as Energy People Power Heating in Stockholm By Bianca | Published 2008-01-08 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/energy-stockholm-jernhuset References: [physorg](http://www.physorg.com/news118498060.html) [Stockholm has crept onto the TrendHunter scene](http://www.trendhunter.com/trends/emotional-cities) quite a lot lately, and show no signs of stopping. Most recently, the innovative Swedes at Jernhuset have found a way to harness human energy through [body heat to raise temperatures](http://www.physorg.com/news118498060.html) of water pipes. A new office building near Stockholm Central Station is in the work's, an area that sees an average of 250,000 commuters. That's a lot of body heat, especially when you consider most are under stress when traveling to the office in the mornings, or rushing home to get the kids on time after work. This project will harness all that energy, or body heat, and use it to [warm the pipes](https://www.trendhunter.com/trends/water-temperature) of the building currently under construction. The $31,200 project is expected to cut heating costs by about 20 per cent which, when you consider the hundreds of million of dollars it takes to contruct a major office tower, is a pretty good deal!
