About Us

Georgia Tech Energy and Sustainability Services (GTESS) was first accredited by ANSI as a standards development organization in the area of Standards and related documents relative to energy management systems on September 23, 1999. GTESS successfully achieved re-accreditation by ANSI in 2006, 2012, and 2022.

A unit of the Enterprise Innovation Institute (EI2) at the Georgia Institute of Technology, GTESS specializes in energy efficiency and engineering; energy and environmental management systems; integrated management systems; environmental regulatory compliance; and, sustainability-based decision processes for industry and government.

In the late 1990’s, Georgia Tech recognized the value of applying a continual improvement-based management system model to the management of energy. As a result, in 2000, GTESS published the American National Standard ANSI/MSE 2000 A Management System for Energy, the first standard globally for a continual improvement-focused energy management system. ANSI/MSE 2000 was revised in 2005 and 2008. The 2008 edition of ANSI/MSE 2000 was an input to the development of the International Standard ISO 50001 Energy management systems—Requirements with guidance for use, which was developed by ISO Technical Committee (TC) 301 under the leadership of the U.S. GTESS is the Committee Manager of the U.S. Technical Advisory Group (USTAG) to ISO/TC 301.

Since 2008, GTESS has played an important role in the development of the Superior Energy Performancecm (SEP) 50001 program. In support of the SEP 50001 program, GTESS has developed ANSI/MSE 50028-1 which sets out the additional SEP requirements for energy management systems, and ANSI/MSE 50028 which contains the requirements for verification bodies providing third-party auditing and certification to SEP.
