US Department of Energy program uses energy management standard
In describing the benefits of the standard, the Department states, ‘In the business world, a popular adage states that you can’t manage what you don’t measure. This principle applies to the world of energy management—an area of growing interest and concern to enterprises around the world due to its potential to help control costs, boost energy efficiency, improve environmental quality and enhance competitiveness’.
The Department of Energy has worked with a number of key bodies to develop the Superior Energy Performance® program, where ‘SEP fosters a results-oriented approach to using the ISO 50001 global energy management system standard, emphasizing measurable savings through a transparent, independent, and highly regarded verification process.’
