Services

Commissioning

Commissioning is not an event — it is a process. We verify that mechanical, electrical and control systems work together efficiently from day one and for years after.

Building systems that perform the way they were designed.

Commissioning for new construction

We provide commissioning services for new buildings, facility additions and renovation projects. Working alongside the owner, designers and contractors, we confirm that building systems are designed, installed, tested and documented to meet the owner’s requirements — supporting more efficient operation for the life of the building.

Retro-commissioning existing buildings

Retro-commissioning applies the process to buildings that were never commissioned. Original design documents are often unavailable, so we perform a forensic study of the building systems. The work usually focuses on energy use — mechanical equipment, lighting and controls — with the goal of improving efficiency, lowering energy costs, finding and fixing existing problems, and tuning up operations through diagnostic testing.

Re-commissioning and ongoing commissioning

Re-commissioning re-applies the process to systems that were commissioned before. Systems drift over time as occupancy and use change, so they should be re-tested on a regular basis. Ongoing commissioning builds that testing into normal operations so performance never falls far behind.

The results are lower energy use and carbon emissions, fewer comfort complaints and equipment that lasts longer.

Questions

Frequently asked

What is the difference between retro-commissioning and re-commissioning?

Retro-commissioning is for buildings that were never commissioned. Re-commissioning repeats the process on systems that were commissioned previously.

How often should a building be re-commissioned?

Regularly. Systems drift as use changes, so periodic re-testing keeps performance and energy savings on track.
