Third-Party Commissioning

At EFI Engineering, we provide independent third-party commissioning services to verify that building systems meet design specifications, industry standards, and owner expectations. Our unbiased approach ensures optimal performance, energy efficiency, and regulatory compliance across all project types.

Our expertise spans commercial, institutional, and industrial facilities, delivering commissioning solutions that improve building performance and long-term reliability. We specialize in third-party commissioning Ottawa and third-party commissioning Toronto, ensuring compliance and performance validation across all project types. We work alongside project teams to identify inefficiencies, validate system integration, and ensure seamless operation.

Third-party commissioning plays a vital role in reducing operational risks, preventing costly system failures, and ensuring compliance with LEED, ASHRAE, and Ontario Building Code standards. By offering independent verification, we help owners achieve confidence in their building’s performance.
