New research building 324, for Technical University of Denmark (DTU). Sustainable, social and technologic solutions work together in building 324. A revolutionary new hybrid ventilation system is incorporated, transporting air through ventilation shafts, run by a heat recovery system and a small support engine fitted on the roof. Photovoltaics cells covers 290 m2 of the roof and solar thermal collectors will be placed along the south-east and west facing facades, making the building a zero-energy building. App. 30 indoor trees will be plated, to help the building brethe and provide a healthy indoor climate. The water usage is minimized by collecting rainwater, and re-using it for flushing toilets and watering the indoor trees. The new building was finished December 2012.
