Developed by the U.S. Green Building Council (USGBC) in 1998, LEED® is a voluntary system of design for buildings and sites. It provides a rating system encouraging the use of technologies that reduce energy and conserve non renewable resources. LEED® was launched in an effort to develop a “consensus-based, market-driven rating system to accelerate the development and implementation of green building practices.” See the chart below for LEED® point summaries for concrete masonry units, segmental retaining walls, and paver products.
