2014 Green Roof Prize winner: 30-year old green roof.
The oldest green roof association in the world, FBB (Fachvereiningung für Bauwerksbegruenung e.V.), has awarded a prize for Green Roof of the Year 2014 to a 30-year old green roof atop the Allianz Insurance Company in Stuttgart, Germany.
In 1981, Allianz decided to build their local headquarters in the heart of Stuttgart, and its green roof was designed and created by a team consisting of Jörg Breuning, CEO at Green Roof Service LLC/Green Roof Technology, architecture firm Brümmendorf, Müller, Murr, Reichmann, and landscape architect Prof. Hans Luz.
The team worked together to lower the environmental footprint of the building by utilizing porous pavements for the green roofs. 30 years later, the greenery is still growing strong, and is a model inspiration for similar buildings around the world.
