Founded in 1918, ANSI oversees the creation, promulgation and use of thousands of norms
and guidelines that directly impact businesses in nearly every sector: from acoustical devices to construction equipment, from dairy and
livestock production to energy distribution, and many more. ANSI is also actively engaged in accreditation - assessing the competence of organizations determining conformance to standards.
ANSI is the official U.S. representative to the International Organization for Standardization (ISO) and, via the U.S. National Committee, the International Electrotechnical Commission (IEC).

Leadership in Energy and Environmental Design (LEED) is basically a third-party certification program. It is a nationally accepted organization for design, operation and construction of high performance green buildings.

The LEED rating systems address both a wide variety of buildings types, including commercial buildings, homes, neighborhoods, retail, healthcare, and schools, as well as every phase of the building lifecycle including design, construction, operations and maintenance.[3] Projects may earn one of four levels of LEED certification (Certified, Silver, Gold or Platinum) by achieving a given number of point-based credits within the rating system.

There are 4 Levels: Certified, Silver, Gold, Platinum
