It is vital that the protection of the building’s fabric and in particular its waterproofing is considered in the green roof design. Roof system design life should be a starting point in the selection of roof systems. Some load-bearing capacities used in design of Melbourne green roofs and walls. It is built on a heritage-listed brick building in Burnley. Note that it is not like a traditional roof garden, in which planting is done in free-standing containers as well as planters that are placed on an easy-to-access roof … Green Roofs or Rooftop Solar Panels add additional load to a roof and its support system. Design Life. If the green roof is designed for use by tenants or the general public, then questions of access and of exiting are taken to another level altogether, from mere convenience to strict standards of safety and security as regulated by Building Regs. Extensive Green Roof - An extensive green roof system is characterized of its vegetation, ranging from sedums to small grasses, herbs and flowering herbaceous plants, which need little maintenance and no permanent irrigation system.The growing medium depth for an extensive green roof system is typically 6 inches or less. Once the vegetation finish has been determined the structural and design considerations and green roof components can be proposed. The next step - Planning the green roof to meet the needs of the vegetation. Schiffer Publishing, Ltd., Atglen, Pennsylvania, 2007. C. If the roofing project is a ‘stand-alone’ project, review the State Construction Office Manual for documentation and bidding requirements. A green roof is a green space that is created by adding various layers of plants and a growing medium to the top portion of a traditional roofing system. of Green Roofs The FLL „Green Roof Guidelines - Guidelines for the Planning, Construction and Maintenance of Green Roofs“ were developed from the „Principles for Green Roofing“ published in 1982 and have been revised several times since 1990. The existing roof may not be capable of supporting an additional load. The dead load associated with the green roofs must be added to appropriate live loads such as snow, wind and human foot traffic to evaluate the feasibility of a green roof design. Extensive Green Roofs . Roofing. The basic anatomy of a green roof consists of vegetation, growing medium, filter membrane, drainage layer, waterproof/root repellant layer, roofing membrane support for plantings above, thermal insulation, vapor control layer, and structural roof support. reduce a building’s heat signature and lower its visual profile Leadership in Energy and Environmental Design (LEED) As with CPTED, some of the Leadership in Energy and Environmental Design (LEED) concepts complement security concerns and others conflict Green Roofs in Sustainable Landscape Design, Steven Cantor, 2008, W.W.Norton [ISBN: 978-0-393-73168-2] These organizations presently are drafting a standard for investigating resistance to root penetration on green roofs. They are recognized as a bench-mark set of guidelines for green roofs in Germany. The University of Melbourne’s demonstration green roof is designed for use by visitors and staff. The Wind Design Standard provides a method of designing wind uplift resistance of green roofs, and the Fire Design Standard provides a method for designing external fire resistance for green roofs. Green Roofs: Ecological Design and Construction by Earth Pledge, foreword by William McDonough. The International Codesprovide guidelines for assign-ing these loads appropriately. Specific system selection recommendations are given later below. All three types of roofs require specific layers of roofing materials not found on regular roofs. State Construction Office “Roofing Design Guidelines and Policies.” This and other guidelines are available on the State Construction Office website. Maximize the benefits of green roof technologies, which can help . Source: FLL Guidelines . different green roof systems and should be specified by the system provider. To ensure structural safety, it’s necessary to have a structural analysis verify that the roof and its support system are capable of supporting the added load without modification.
