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
