COMMISSIONING BENEFITS

5

Commissioning Benefits The value of a whole building commissioning process is realized by the owner, project designers, contractors and ultimately occupants of the building.

Owners benefit from having an advocate and fewer delays. Early on, commissioning agents identify and document Owner Project Requirements (OPR). Throughout design and construction, they continually ensure the building fulfills the owner’s performance expectations.

Designers benefit from verification of design intent as well as reduced time troubleshooting installation issues. Commissioning agents capture installation deficiencies during functional performance testing.

Contractors save on time and labor from the discovery and resolution of issues, which can range from operational oversights, installation errors, incorrect programming or manufacturing defects.

Building End Users experience the built environment as it was designed — one that is comfortable, healthy, maintainable and sustainable.

A Path to High Performance Buildings Carefully designed building systems focused on maximum energy performance and efficient operations can save facility owners and operators significant dollars over the life of the building, but only if these systems are built, operated and maintained to design specifications. Commissioning is a critical process toward achieving the highest performance outcomes for a building.

Complex building systems are not one-size-fits all. They are tailored to meet each building’s unique performance requirements, driven by location, energy impact, resiliency requirements, operational and maintenance goals and many other design factors.

The commissioning agent evaluates all building systems as a complete operational unit, thus confirming performance and bringing assurance to the client the final building performs as designed.

“Commissioning was a security blanket for us. I work in the financial world, not the design and construction world. Commissioning ensured everything operated as designed, and it kept us from having to babysit.”

OUR COMMISSIONING SERVICES

7

Commissioning is a systematic process of ensuring all building systems perform interactively according to the design intent and the owner’s operational needs. The process evaluates building equipment, subsystems, operation and maintenance procedures, measuring performance of all building components individually and as a system.

Retro-Commissioning is a systematic process for improving and optimizing an existing building’s performance.

Recommissioning is commissioning of an existing building that has already gone through the commissioning process to address issues that may have arisen since the original commissioning. It provides additional opportunities to improve efficiency and performance.

75+

Years Engineering Expertise

Continuous Commissioning is an ongoing process for existing buildings to resolve operating problems, improve building comfort and safety, optimize energy use and identify retrofits. Data is continually gathered and compared against energy benchmarks to measure efficiency and ensure equipment and systems operate as designed throughout their useful lives.

Building Enclosure Commissioning is a qualitybased process for evaluating the performance of a facility envelope to determine if a project is meeting the defined objectives, standards, and requirements of the owner. Working with the project team it is a collaboration to discuss challenging building enclosure detailing, specifications, and other components.
