environmentally friendly building concept

( Banda aceh polytechnic building )
a building not only looks good from its shape, but of course I am very interesting, when the concept is also environmentally friendly, for example from the concept of lighting, where the inside of the building can get adequate illumination from the sun.
obviously this will bring huge profits, of course with good light access, will save considerable electrical energy.
I saw aceh polytechnic building, very cool because it has implemented environmentally friendly building.
