Even a relatively new building or facility must be assessed periodically to ensure that systems and equipment perform as intended. ENGIE Services U.S. uses a holistic evaluation process to ensure that mechanical, electrical, and control systems are Energy Effective™ This means they meet ever changing business and operational needs. Many of the recommendations we identify are relatively small operations and control improvements that cost little or nothing to implement. The result is dramatically better facility performance including lower expenses, higher productivity, and increased sustainability.
