Commissioning Agents Are Essential for Building Performance

In today’s construction and retrofit landscape, building commissioning has evolved from an optional quality-control measure into a critical service for performance, compliance, and efficiency. Whether it’s a LEED-certified new build, a tenant fit-up, or a complex HVAC system upgrade, third-party commissioning agents (CxAs) play a vital role in delivering systems that perform as intended.

At EFI Engineering, we provide independent, third-party commissioning services to help building owners, architects, and contractors meet regulatory requirements, energy goals, and occupant expectations—without conflicts of interest.

What Is a Commissioning Agent?

A Commissioning Agent (CxA) is a qualified professional or firm responsible for verifying that a building’s systems—mechanical, electrical, plumbing, life safety, and more—are designed, installed, tested, and performing according to the owner’s project requirements (OPR).

Unlike internal teams or design consultants, a third-party CxA provides objective oversight, advocating for the owner’s best interests throughout design, construction, and occupancy.

Why Use a Third-Party Commissioning Firm?

Hiring a third-party commissioning agent offers several key advantages:

✅ Independent Verification

Third-party CxAs bring an unbiased eye to the project. EFI Engineering acts independently from design teams and contractors to identify issues early and ensure quality throughout.

✅ Code Compliance

In Ontario, commissioning is often required under:

• OBC SB-10 Energy Efficiency Requirements

• Ontario Regulation 851 (for industrial systems)

• LEED, WELL, and Zero Carbon Building certifications
  EFI supports projects requiring integrated system testing per CAN/ULC-S1001, backup power validation, and more.

✅ Reduced Rework and Delays

By identifying design conflicts, install errors, and controls issues during construction, commissioning prevents costly rework and project delays.

✅ Improved Energy Efficiency

A properly commissioned building operates more efficiently, reducing energy consumption and lifecycle costs.

✅ Better Occupant Experience

EFI’s commissioning ensures your HVAC, lighting, life safety, and automation systems operate reliably, improving comfort and safety for occupants from day one.
