It's 7:30 a.m. on a wintry morning in downtown Stockholm and a sea of Swedes are flooding Central Station to catch a train to work. The station is toasty thanks to the busy shops and restaurants and the body heat being generated by the 250,000 commuters who crowd Scandinavia's busiest travel hub each day. This heat used to be lost by the end of the morning rush hour. Now, however, engineers have figured out a way to harness it and transfer it to a newly refurbished office building down the block. Unbeknownst to them, these sweaty Swedes have become a green energy source: "They're cheap and renewable," says Karl Sundholm, a project manager at Jernhusen, a Stockholm real estate company, and one of the creators of the system. Using excess body heat to warm a building is not a new concept — the Mall of America in Minneapolis recycles the heat generated from shoppers' bodies to help regulate the temperature of the massive complex during Minnesota's dreadful winters. But Stockholm has taken the idea a step further by successfully transferring excess body heat from one building to another. "This is old technology, but used in a new way," Sundholm explains. "It's just pipes, water and pumps, but we haven't heard of anyone else using this technology in this way before." (See the top 10 green ideas of 2009.) Here's how the system, which began operating this month, works: the heat generated by the commuters is captured by the station's ventilation system and used to warm water in underground tanks. The water is then pumped through pipes to the 13-story Kungbrohuset office building about 100 yards away, where it is incorporated into the main heating system. Not only is the system environmentally friendly, it's also cost-effective, says Jernhusen, which owns both the station and the office building. In the long run, the company expects to lower the energy costs in the office building by as much as 20% per year. And constructing the new heating system, including installing the necessary pumps and laying the underground pipes, only cost the firm about $30,000, Sundholm says. "It pays for itself very quickly," he adds. "And for a large building expected to cost several hundred million kronor to build, that's not that much, especially since it will get 15% to 30% of its heat from the station."
