Denmark’s first public CO2-neutral building just opened. The new building, Green Lighthouse, designed by the Danish Christensen & Co arkitekter was inaugurated on the 20th October 2009 and serves as an example in several ways. It is the first carbon neutral public building in Denmark consuming 90% less energy than the average Danish university building. 75% of the reduction of the energy consumption is due to the architectural design.
The building has made so much of a stir that it is going to serve as a showcase for sustainable building at the Climate Conference in Copenhagen in December this year.
The parties involved in the project are the Danish Ministry of Science, Technology and Innovation, the University of Copenhagen, the City of Copenhagen and the window producers VELUX and VELFAC.
“Green Lighthouse will be used by students at the Faculty of Science. In student services they will be able to get information concerning everything from career guidance to exams and subjects. Furthermore, a faculty club for scientists, and others affiliated with the faculty, will be housed in Green Lighthouse.”
“Green Lighthouse’s pivotal point and primary energy source is the sun. The house is 950 m2 and is constructed according to the active house principle, meaning that it generates energy. It has its own energy supply containing a combination of solar energy, heating pumps and a district heating never seen before. Green Lighthouse is an energy-efficient building of high architectural quality, allowing a great amount of daylight to enter. The natural ventilation assures plenty of fresh air and a healthy indoor climate.
Through energy design and visionary architecture, the building’s energy consumption is reduced by around 3/4 compared to present building standards. This means that the building is categorised as a class 1, low energy building according to Danish building regulations (BR 08).”
