The first sod of Copenhagen University’s first climate-friendly building, Green Lighthouse, was turned today at Tagensvej in Copenhagen.
The building will balance the need for energy-efficient building with architectural quality, daylight and a healthy indoor climate.
The Danish Minister for Science, Technology and Innovation, Helge Sander, turned the first sod together with Copenhagen University Dean Ralf Hemmingsen, Technical and Environment Mayor of Copenhagen Klaus Bondam, VELUX Marketing Director Michael Rasmussen and three representatives from the building consortium behind Green Lighthouse: Michael Christensen of CCO arkitekter, Klaus Peitersen of Hellerup Byg and Bente Andersen of COWI.
Before Helge Sander picked up the spade and set the project in motion, he said:
“This spade will move the first earth in the belief that new-thinking, public-private joint ventures and the will to find energy and climate-friendly solutions will see the realisation with the Green Light House concept.
Inspiration to the building sector
And it was precisely the energy and climate-friendly solutions for the university of the future that were the pivotal issues for the minister.
“Naturally, there are some innovation costs when you are striving for the objective of creating CO2-neutral low-energy buildings for the universities. It is, therefore, our hope that sustainable building, combined with beautiful architecture and a good indoor climate, will inspire others to contribute to the building sector’s knowledge bank,” he said.
The climate building will house Natural Sciences
Green Lighthouse will house, among other things, a Faculty Lounge, meeting facilities and Student Services for the Faculty of Natural Sciences. This places great demands on functionality as well as the climate-friendly aspect. The building will provide inspiration at a time when the city and university are in the spotlight of the UN Climate Conference in Copenhagen.
“Green Lighthouse is part of our ‘green’ campaign at Copenhagen University. It is visionary building that combines sustainability with an aesthetic and functional framework that makes it user-friendly for the students, staff and visitors. With the first turf now turned, we can start the building process itself – and we can’t wait for the day when it is ready for occupation,” says Ralf Hemmingsen, Dean of Copenhagen University.
Behind the Green Lighthouse project, there is a steering committee consisting of the University itself, the University and Property Agency, VELUX, VELFAC and the City of Copenhagen.

Green Lighthouse will be home for the students and staff at the Faculty of Natural Sciences. It will house course administration, a Faculty Club, meeting facilities and Student Service.
The vision underlying Green Lighthouse is to build a sustainable building with the lowest possible CO2
The symbol of the building is the sundial, signalling light as a theme in natural science. It is an original and powerful architectural concept that will set its mark on Nørre Campus. With its green cladding, the building will create a visible and attractive centre point for the area. Green Lighthouse will stand out with its own clear identity and yet give identity to the whole Nørre Campus area. The building will this live up to its name of being a visible landmark for the campus and the climate ambitions behind project Green Lighthouse.
Green Lighthouse focuses on daylight as the source of light, with spaces that are pleasant to spend time in and work in. With open and well-illuminated rooms and a good indoor climate, Green Lighthouse will be a comfortable and congenial place for the students, staff and visitors.
The energy concept of Green Lighthouse
- Areal: 950 m2 in three storeys
- Owner: University and Property Agency
- Architect: Christensen & Co Arkitekter A/S
- Contractor: Hellerup Byg
- Engineer: COWI
The intention of the energy concept is to make Green Lighthouse as CO2 -neutral as possible. Green Lighthouse will be a completely new energy concept experiment, a combination of energy supplies from district heating, solar cells, solar heating and cooling, and seasonal storage.
This energy concept, developed by COWI, is a new solution that uses district heating to drive heat pumps. Using district heating instead of electricity reduces CO2 impact. It ensures maximum utilisation of renewable energy sources and that interplay means that the concept uses the sun both for cooling in summer and improving heat pump operation in winter. The concept harnesses solar heating energy from south-facing windows to heat the floors and to feed earth storage throughout the seasons. A heat pump ensures that solar heating and geothermal heating and cooling are distributed around the building. This allows the building to achieve maximum utilisation of the district heating that kicks in if there is no solar heat available from the storage.
Figures and distribution
The building’s preliminary heating consumption is estimated as being 22 kWh/m2/year.
Heating supplies are expected to come from 35% solar energy, 55% heat pump energy and the rest directly from the district heating network. Most of the electricity for lighting, ventilation and pumps will be supplied by 45m2 of solar cells on the roof. About 50% of the building’s energy requirements are expected to be met by renewable energy sources. Combined with the designed low-energy needs, this will mean an energy saving of 80% of the needs of a conventional building.
