Gut Karlshöhe, Hamburg (GER)

Gut Karlshöhe in Hamburg has served as an institution for environmental education since 1989. The 1100 square metre historic barn, built on the estate in 1920, was facing dereliction. Today, it shines in renewed splendour – lovingly and sensitively modernised as "Efficiency House 55". With its seminar rooms, Youth Research Workshop, exhibition and restaurant, the former barn has become the centrepiece of Gut Karlshöhe. Dieter Ohnesorge, CEO of the Hamburg Foundation for Climate Protection: "We chose Nimbus LED products for the lighting because they meet our requirements in terms of energy-efficiency and sustainability while offering a high light quality and flexibility in their use."
