“No energy management program is complete without commissioning.”

Lawrence Berkeley National Laboratory

Our comprehensive approach to building commissioning ensures the facility owners/managers move into fully functional buildings, and our detailed documentation surpasses the requirements established by the United States Green Building Council (USGBC) for Leadership in Environmental and Energy Design (LEED®) certification.

Over the last decade, we have commissioned numerous building types ranging from small commercial office buildings to large complex medical and laboratory campuses for new construction as well as existing buildings. The developer community is also recognizing the benefits of commissioning, specifically the non-energy related impacts such as improved operating systems, 30% reduction in change orders of systems that were commissioned, and elimination of holdover and damages and on-time rent commencement.
