Earning LEED Credits with Asphalt
s people strive for a greener and more sustainable world, more and more construction projects are looking to be Leadership in Energy and Environmental Design (LEED) certified through the US Green Building Council. To be LEED certified, a project must meet certain sustainability goals (credits) in areas such as sustainable sites, water efficiency, materials & resources, and others. Unfortunately, it seems many people overlook asphalt as a way to help earn LEED credits for their project. Using asphalt can help a project obtain 6 or more credits. Using pervious asphalt pavement for the parking lot of a project can help earn credits for stormwater quality and quantity control. By properly designing and installing pervious asphalt pavement, the amount of runoff from the site as well as the pollutant load can be reduced to levels low enough to help earn LEED credits. By installing a storage basin below the pavement surface and treating/reusing the captured runoff for irrigation, additional LEED credits can be earned. When it comes to earning a credit for reducing the heat island effect, most people think that concrete is the only option because it is more reﬂective than asphalt. However, asphalt can also be used to help
earn heat island effect related credits for a project. By providing shade to the hardscape from trees, from structures that have a solar reﬂective index (SRI) of at least 29, or from a structure covered in solar panels, the credit can be attained. Additionally, a reﬂective coating or colorant can be used to increase the SRI of the asphalt. There are a number of credits to be earned under LEED for using recycled materials. Because old asphalt pavement and shingles are recycled into new asphalt pavement, using asphalt pavement can help a project earn these credits. Credits can also be awarded for using regional materials. Regional materials are deﬁned as those that have been extracted, harvested, or recovered, as well as manufactured within 500 miles of the project site. For both the recycled materials and the regional materials credits, the credits are awarded based on reaching a certain percentage for the site. Therefore, in addition to using asphalt, other strategies for using recycled and regional materials will need to be implemented to earn LEED credits. LEED, albeit the most well known, is not the only certiﬁcation program available. Other programs include the Sustainable Sites Initiative, (SSI, an interdisciplinary effort by the American
Society of Landscape Architects, the Lady Bird Johnson Wildﬂ ower Center, and the US Botanic Garden) along with Greenroads (developed by the University of Washington and CH2MHill). SSI is similar to LEED in its certiﬁcation program and credits, however, it can more easily be adapted to a site without buildings. Greenroads, on the other hand, applies solely to sustainable roadway design and construction. It includes credits for stormwater quality and quantity, use of regional and recycled materials, equipment and pavement emissions reductions, as well as credits for using pervious pavement, warm mix asphalt, cool pavement, and quiet pavement. Although often overlooked as a green product, asphalt can help attain credits under the various credit programs available. The asphalt industry should be aware of how credits under each certiﬁcation system can be obtained by using asphalt and promote its use in such projects. ✪ For more information on this subject, please contact Mary Ellen Schulle or Gary Nicholls with Westward Environmental, Inc., at email@example.com, gnicholls@ westwardenv.com, or by telephone at 830249-8284.
