Stockholm's Central Station Harvests Body Heat

by Andrew Price

January 13, 2011

Central Station in Stockholm is the largest train station in Sweden. About 250,000 passengers pass through it each day. All those moving bodies generate a lot of heat, and even in Sweden's chilly climate, it's more than the building needs. So the real estate company that owns the building is using heat exchangers to transfer Central Station's excess heat to water, which is then piped over to heat another building across the street. Apparently the innovation lowers the energy costs of the office block by 25 percent.

This is just yet another reminder that we're surrounded by opportunities to use energy more efficiently. And, of course, it's giving Sweden a head start on a future with more expensive oil and gas.
