Commissioning

Commissioning is a systematic process that ensures new building systems and equipment meet the owner’s project requirements by verifying the design, installation, operation, maintenance, and setpoints. Learn more about commissioning and retro-commissioning below:

What is commissioning (Cx)?

Commissioning (Cx) is a systematic process that ensures new building systems and equipment meet the owner’s project requirements by verifying their design, installation, operation, and maintenance. The process consists of detailed and systematic testing of equipment like boilers, chillers, pumps, air handlers, and controls —anything in a building that uses energy and affects occupant comfort. Commissioning should always be performed by a certified commissioning professional.

Why is commissioning important and what are its benefits?

At its core, commissioning enables issues to be caught and fixed early, thereby preventing occupant complaints and reducing energy and maintenance costs. Commissioning is important because its process of detailed testing and inspections ensures equipment was installed correctly and is working at peak performance. Often equipment is installed improperly or incompletely—gaps in ductwork, missing sensors, or incomplete software—and owners are unaware of the construction issues until after the warranties have expired. Commissioning also uncovers when installed equipment doesn’t match its approved design, which has the potential to cause major problems and expenses down the line.

How can commissioning save me money and make my building green?

When building systems are installed incorrectly, they cost building owners in the short and long term: Equipment consumes more energy than they should, their lifespan is much shorter, and their improper performance can damage other equipment. Commissioning enables issues to be caught and fixed early, thereby reducing energy and maintenance costs. Lower energy use is an important condition for green building certifications, and many green building programs require commissioning to ensure all equipment is performing as intended.

When is commissioning required?

Commissioning of newly installed equipment is required by several municipalities, including New York City and Philadelphia. This includes new equipment being installed in existing buildings and new construction. Whether commissioning is required depends on the particular type of equipment and its size, and can include HVAC, plumbing, refrigeration, renewable energy, energy storage, and control systems.

It’s important to note, not all commissioning is equal. Sometimes commissioning is done in name only, so equipment problems are not discovered and the building does not receive any benefits beyond basic compliance. Hiring a committed commissioning professional ensures you receive the full benefits of commissioning, namely major energy and maintenance cost savings.

What is retro-commissioning (RCx)? How is it different and when do I need it?

Retro‑commissioning (RCx), also known as "existing building commissioning," can reduce a building’s energy costs by optimizing the building system performance. Like commissioning, retro-commissioning is mandated for a variety of local laws and green building certification programs and should be conducted by a certified commissioning professional. Although retro-commissioning may not be required for a given project, it’s still a very good idea to do in order to keep costs down and extend equipment life, thereby delaying expensive capital improvements
