Sun Rock building by MVRDV in Taiwan

The façade maximises this solar potential with an all-over array of photovoltaic panels (mixed in with windows, where required). The angle of these panels is adjusted on all parts of the façade to maximise their energy-generating potential. As a result of these measures, the building can generate 1.2 million kilowatt-hours of clean energy per year – an amount of energy equivalent to burning over 100 tons of crude oil – and making the building completely self-sufficient.

I’ve spotted an unusual facade cladding with apparently PV panels in Lausanne, near EPFL campus.
