Henning Larsen designs school in Denmark that captures more carbon than it emits

The Feldballe School extension in Rønde, Denmark has been designed by architects Henning Larsen using almost entirely bio-based materials such as wood and straw. The building uses natural and passive ventilation systems, together with solar panels, which are expected to eliminate energy consumption on a daily basis. The architects are now scaling up the model for a 13,000-square-meter project. Photo Rasmus Hjortshøj.  Henning Larsen
