Concrete Pavers Earn LEED Points
Within the North American design and construction community, a means for addressing sustainability or ‘green building’ is through LEED® or Leadership in Energy and Environmental Design.
Developed by the U.S. Green Building Council (USGBC) in 1998, LEED® provides voluntary guidelines for reducing energy and wasted resources from building and site design. Interlocking Concrete Pavements (ICP), including Permeable Interlocking Concrete Pavements (PICPs), are eligible for LEED® credits under USGBC and CaGBC guidelines.
SUSTAINABLE SITES LEED® CREDIT
ICP can meet the requirement to help reduce urban heat islands (thermal difference between urban and rural areas), minimize impacts on microclimates and in wildlife habitats. This is accomplished through increased albedo (a measure of solar radiation reflected from a surface) or using a pavement system with less than 50% imperviousness. PICP has substantially higher reflectivity than conventional asphalt pavement and the is 100% pervious.
PICP can meet the Sustainable Sites requirements which limit runoff and water pollution by managing stormwater. The pavements reduce runoff-generating impervious cover and decrease the rate and quantity of runoff. PICP meets these credits through the filtering action of the base that reduces total suspended solids and phosphorous in runoff, as well as other pollutants.
CONSERVATION OF MATERIAL AND RESOURCES, RECYCLED CONTENTS CREDIT
ICP typically meets the requirement under the USGBC LEED for new construction where at least 20% of the building products should be manufactured within a radius of 500 miles (800 km) of the project. Most paving units are locally manufactured and delivered to projects within 500 miles (800 km). To find the closest manufacturer or distributor, visit the ICPI Find a Member section.
The U.S. Green Building Council (USGBC) and the Canada Green Building Council (CAGBC) certifies sustainable businesses, homes, hospitals, schools, and neighborhoods. USGBC is dedicated to expanding green building practices and education and its LEED® (Leadership in Energy and Environmental Design) Green Building Rating System™.
