Retro-commissioning is a structured process for existing buildings that verifies building systems and equipment are operating as intended and aligned with current performance needs. For new buildings or new systems and equipment that require Commissioning services, click here.
By identifying inefficiencies and optimizing system operations, retro-commissioning improves energy efficiency, enhances occupant comfort, and extends equipment lifespan without requiring major capital upgrades.
Through functional performance testing and system reviews, our team evaluates HVAC systems, domestic hot water systems, building management systems (BMS), lighting systems, and other critical infrastructure. This process reduces energy waste, prevents operational issues, and ensures systems are properly operated and maintained over time.
Retro-commissioning also plays a critical role in regulatory compliance. For buildings subject to NYC’s Local Law 87 (LL87), it is a required component of the ten-year compliance cycle and must be completed alongside an ASHRAE Level II energy audit for buildings over 50,000 square feet. At EN-POWER GROUP, our certified commissioning professionals help building owners meet these requirements while improving overall system performance and alignment with energy standards.
