Green roof structural design.

The systems used to stabilize green roof installations on slopes greater than 2 12 depend on the underlying structural capacity and design and the steepness of the roof. Proper selection of agriculturally durable materials structural engineering design and review and responsible water handling should all be considered to achieve maximum energy efficiency and perhaps leed recognition. Examples range from geotechnical matting systems like enkamat to slope restraint systems cable grids and mechanically attached structural grids. A structural engineer s advice is essential to ensure comprehensive design development based on the building s construction condition and weight loading capacity.

Shallow pitched green roof 5 25 the structure of a shallow pitched green roof differs slightly from the structure of a. Incorporating gardens or other forms of green roof plantings can be an attractive alternative to traditional building construction. Of green roofs and recommended structural design specifications and strategies will also be presented. A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium planted over a waterproofing membrane it may also include additional layers such as a root barrier and drainage and irrigation systems.

Flat green roof 0 5 flat roofs are ideal as green roof. The system structure for a flat water retaining green roof consists of a drainage layer with filterfleece extensive roof garden substrate and a vegetation blanket.
