Green building systems like Leadership in Energy and Environmental Design (LEED) certification and the ICC 700 National Green Building Standard will likely continue to drive demand for green building projects. In order to achieve green building certification, a green building project must fulfill a number of requirements, such as energy and resource-efficiency and the use of sustainable building materials. The U.S. government has adopted LEED and other similar green buildings certifications for public buildings.
LEED is one of the most popular green building certification programs worldwide, with more than 96,000 LEED projects in 167 countries and territories. Developed by the U.S. Green Building Council (USGBC), it provides building owners and operators with a framework for identifying and implementing practical and measurable green building design, construction, operations, and maintenance solutions. In addition, obtaining a LEED-certification projects a positive environmental image to the community. LEED addresses five focused areas: sustainable sites, water efficiency, energy and atmosphere, materials and resources and indoor environmental quality. Studies have shown that workers in these environments have increased labor productivity, job retention and days worked.
