Green Lighthouse

There is a building in Copenhagen called the Green Lighthouse. It is the first carbon-neutral building in Denmark that is open to the public. (No word on how many of that sort of building there are in the country about which the public knows nothing.)
  

Exterior view, complete with omnipresent Danish biker.

It's a very good looking building. And obviously very energy efficient- uses only 30 kilowatts per square meter, as opposed to the Danish standard of 97 kw/square meter.

The interior. White, just for a change.

While all-over white may seem a bit bland and medical, thanks to the abundance of sunlight, it actually makes the inside of the building more exciting. Every slight change in the exterior conditions is transmitted to the occupants. Also of note, the BMS system automatically raises and lowers the blinds of individual windows when they begin to receive direct sunlight.

That's the same cladding that our professor then proceeded to mock, calling is a waste highly advanced building material. It is only being used, he says, in order to make the lighthouse look as modern and futuristic as its design is underneath. Clearly he was not impressed.
