March 2013 Orion, the new central educational facility of Wageningen University, is almost ready. The building is situated between Atlas and Forum as the third monolith on the central green of the campus. The typical pentagonal floorplan derives from a smart stacking of different functions, such as restaurants, a large auditorium (that can be subdivided to become six separate lecture halls) and several floors containing laboratories. Through a smart orientation an optimal balance between daylight admission and climate control is achieved, making this a very sustainable low energy building. The building will be operational come may.
