Green Lighthouse is Denmark's first CO2 neutral public building and home to the Faculty of Science at the University of Copenhagen. The building's circular shape and the adjustable louvres of the fašade mirror the course of the sun. The sun being the predominant source of energy is the overriding design concept behind the new building. Green Lighthouse is based on a whole new experiment with an energy concept, consisting of a supply combination of district heating, photovoltaics, solar-heating, cooling and seasonal storage.
70% of the reduction of the energy consumption is the direct consequence of architectural design.
To achieve carbon neutrality, many green design features were incorporated to reduce energy use and provide a holistic and healthy indoor environment for students and faculty. The building itself was oriented to maximize its solar resources.
