Zurich-Kloten International Airport in Z?rich (ZRH) is the largest airport in Switzerland and strives to symbolize a modern, comfortable and green airport. ZRH is home to a nature conservation area that covers an area of approximately 74 hectares and is only a few meters away from the edge of the runways. ZRH operations and management focus strongly on communication in the area of environmental protection, and publish an annual environmental report. ZRH has two recent large greenroof projects which demanded a high level of effort, coordination, and communication from all participants because of its sensitive location and accompanying security measures.Completed in 2001, the 8,000 m2 (86,111 sf) multi-story Car Park B at ZRH also demanded specific logistic skills and equipment in bringing up the substrate to the high 50 m (164?) roof level, and a pneumatic pump was required to blow substrate and gravel onto the roof’s surface.

Construction work was performed during daily airport vehicle and airplane traffic. The extensive ZinCo Green Roof System contains a combination of planted Sedum shoots and hydro-seeding in a sedum carpet. An anti erosion jute control net “JEG” was installed afterwards to protect the plants against wind uplift.
