MSE Standards

GTESS develops standards in the areas of energy management and energy management systems. GTESS standards are designated with “MSE” in the prefix, which refers to “Management System for Energy”— a tribute to the very first American National Standard developed and published by GTESS, ANSI/MSE 2000-2000 A Management System for Energy.  The public links on this page provide access to public announcements on GTESS standards activities, a listing of ANSI-approved MSE Standards, information on how to request a formal interpretation of a current MSE Standard, along with information on how to contact GTESS.
