Using Excess Warmth From The Paris Metro To Heat Homes
A public housing building in Paris is undergoing environmentally friendly renovations and will be heated with the help of activity from the metro train station below. Heat generated from trains and passengers will be channelled up an existing staircase into the structure above.
Planet Ark explains how it works:
The calories emitted by passengers, around 100 watts per person, combined with the heat from trains moving along tracks and the underground location of the metro mean that corridor temperatures are 14-20 degrees Celsius all year around.
The project, which is based on geothermal technology, aims to draw heat from subterranean passages and move it to heat exchangers before supplying heating pipes. The system will complement district heating.
The project should slash carbon dioxide emissions by a third compared to using a boiler room connected to district heating
