Designation:E277714Standard Guide forVegetative(Green)Roof Systems1This standard is issued under the fixed designation E2777;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide identifies terminology,principles and funda-mental concepts including those related to sustainability,tech-nical requirements of construction,and types of vegetative(green)roof systems used on buildings.1.2 The considerations for sustainable development relativeto vegetative(green)roof systems are categorized as follows:environmental,social,and economic as consistent with GuideE2432.(See Appendix X1.)1.3 This guide discusses technical requirements for vegeta-tive(green)roof systems pertaining to the following catego-ries:plants,media,wind scour resistance,soil reinforcement,separation or filter layers,drain layers,water retention layers,protection layers,and root penetration barriers.1.4 This guide addresses intensive and extensive vegetative(green)roof systems for roofs up to 15%slope.Roofing/waterproofing membranes and insulation are key componentsof vegetative(green)roof systems,but technical requirementsregarding their role in such roof systems is beyond the scope ofthis guide.NOTE1ASTM Technical Committees D08 and C16 have jurisdictionover the development of standards for roofing/waterproofing membranesand insulations,respectively.Some of their existing standards may behelpful in the evaluation of membranes and insulation used in vegetative(green)roof systems.As these two committees develop standards for suchroofs,this guide will be revised appropriately.1.5 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2,3C88 Test Method for Soundness of Aggregates by Use ofSodium Sulfate or Magnesium SulfateD1079 Terminology Relating to Roofing and WaterproofingD1987 Test Method for Biological Clogging of Geotextile orSoil/Geotextile FiltersD2974 Test Methods for Moisture,Ash,and Organic Matterof Peat and Other Organic SoilsD3786/D3786M Test Method for Bursting Strength of Tex-tile FabricsDiaphragm Bursting Strength Tester MethodD4354 Practice for Sampling of Geosynthetics and RolledErosion Control Products(RECPs)for TestingD4439 Terminology for GeosyntheticsD4491 Test Methods for Water Permeability of Geotextilesby PermittivityD4595 Test Method for Tensile Properties of Geotextiles bythe Wide-Width Strip MethodD4716/D4716M Test Method for Determining the(In-plane)Flow Rate per Unit Width and Hydraulic Transmissivityof a Geosynthetic Using a Constant HeadD4751 Test Method for DeterminingApparent Opening Sizeof a GeotextileD4759 Practice for Determining the Specification Confor-mance of GeosyntheticsD4873 Guide for Identification,Storage,and Handling ofGeosynthetic Rolls and SamplesD5262 Test Method for Evaluating the Unconfined TensionCreep and Creep Rupture Behavior of GeosyntheticsD5617 Test Method for Multi-Axial Tension Test for Geo-syntheticsD5818 Practice for Exposure and Retrieval of Samples toEvaluate Installation Damage of GeosyntheticsD6637 Test Method for Determining Tensile Properties ofGeogrids by the Single or Multi-Rib Tensile MethodD7361 Test Method for Accelerated Compressive Creep ofGeosynthetic Materials Based on Time-Temperature Su-perposition Using the Stepped Isothermal Method1This guide is under the jurisdiction of ASTM Committee D08 on Roofing andWaterproofing and is the direct responsibility of Subcommittee D08.24 on Sustain-ability.Current edition approved May 1,2014.Published June 2014.DOI:10.1520/E2777-142For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Whenever a specific version of a standard is not identified,the most recentedition of the standard shall apply.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 E108 Test Methods for Fire Tests of Roof CoveringsE136 Test Method for Behavior of Materials in a VerticalTube Furnace at 750CE631 Terminology of Building ConstructionsE2114 Terminology for Sustainability Relative to the Perfor-mance of BuildingsE2396 Test Method for Saturated Water Permeability ofGranular Drainage Media Falling-Head
