LEED, or Leadership in Energy and Environmental Design, is the most widely used green building rating system in the world.

Available for virtually all building, community and home project types, LEED provides a framework to create healthy, highly efficient and cost-saving green buildings. LEED certification is a globally recognized symbol of sustainability achievement.

WELL is the leading tool for advancing health and well-being in buildings globally.

WELL was developed by integrating scientific and medical research and literature on environmental health, behavioral factors, health outcomes and demographic risk factors that affect health with leading practices in building design, construction and management.

Administered by Green Business Certification Inc. (GBCI), SITES offers a comprehensive rating system designed to distinguish sustainable landscapes, measure their performance and elevate their value.

SITES certification is for development projects located on sites with or without buildings—ranging from national parks to corporate campuses, streetscapes to homes, and more.

An innovation of IFC, a member of the World Bank Group, EDGE is a fast and easy to use mass market transformation tool. It empowers developers and builders to quickly identify the most cost effective ways to reduce energy use, water use and embodied energy in materials.
