I’m not sure this is a trend as such, but the concept is certainly interesting. On top of the Copenhill power plant in Copenhagen the architect has placed a dry ski-slope. Why? Why not? The architect uses the term “hedonistic sustainability”.
Hedonistic sustainability
What’s more interesting that the power station is in the middle of the city right beside its users, which means much more efficient delivery of ‘combined heat and power’ and indeed delivery of human detritus for converting into said heat and power – the ski slope is a clever way to get local support. 🙂
