Green Roof Abstract

Green roof application and performance.

Green roof abstract.

The present chapter provides a description of the most commonly utilized irrigation systems and analyzes the common maintenance procedures of green roofs. Research on the green roof has been raised expeditiously over the past decade. This review paper includes the history of the green roof green roof components and multiple benefits environmental social and economical. Container gardens on roofs where plants are maintained in pots are not generally considered to be true green roofs although.

Abstract green roof infrastructure promises to become an increasingly important option for building owners and community planners. As we move into the 21st century green roofs can address many of the challenges facing urban residents. 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. Gsa s green roof report estimated that green roofs on commercial and public buildings provide a payback based on 50 year average annual savings of about 6 2 years nationally internal rate of return of 5 2 and an roi of 224 based on a net present value of 2 7 square foot.

Green roofs have considerable potential for stormwater source control both for new developments and as a retrofit option.

In the united kingdom the lack of local quantitative performance data and modelling tools together with more general barriers to sustainable drainage systems suds implementation may explain their limited. Extensive green roofs have media depths ranging from 5 15 cm whereas intensive green roofs have media depths greater than 15 cm capable of sustaining vegetation with deeper root structures and that is less drought tolerant luckett 2009.

Primary green roof costs are related to installation and maintenance. There are two types of green roofs. Green roofs have a versatile maintenance and irrigation system installation depending on their type intensive semi intensive or extensive and plant species selection. Green roof have been proposed as the sustainable practice to mitigate the adverse effects of urbanization.

Green roofs can manage much or all of the runoff that would otherwise be generated by a building s roof area. The objective of this chapter is to present the economic benefits of a green roof in terms of its public and individual benefits summarize the total costs of a green roof throughout its lifecycle. Along with the green roofs themselves it is also common to install sensors to measure various environmental parameters that are affected by or important to the operation of the roof.
