The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) Standard 202-2013 defines commissioning (Cx) as “a quality-focused process for enhancing the delivery of a project.” It verifies and documents that all commissioned systems and assemblies are planned, designed, installed, tested, operated, and maintained to meet the Owner's Project Requirements (OPR).Put simply, commissioning aligns teams, resources, and timelines to the owner's requirements to deliver a functional, compliant, and energy-efficient building. In a nutshell, commissioning aims to achieve First Time Quality.

Including commissioning in your project delivers several measurable benefits:
This comprehensive guide on commissioning covers facts you need to know and the best practices for a successful commissioning process in three main sections:
The best practice is to begin the building commissioning process before construction starts. Early involvement of the commissioning authority (CxA) helps reduce design rework, change orders, and costs.
A typical project commissioning process involves the phases below:
The planning stage involves pre-planning, feasibility studies, establishing the owner's needs, scope, and design requirements for the project. The project manager, commissioning authority, and other stakeholders work together to ensure alignment throughout the process and provide an unbiased assessment to the owner. The commissioning plan involves the activities below:
The commissioning team comprises the core team that will be part of the construction process. This group consists of:
The design phase translates the Owner’s Project Requirements into design decisions and documentation.
Here, the commissioning provider:
Using commissioning software at this stage helps automate documentation, track updates, and streamline communication between teams.
The project manager and agent review and revise the commissioning plans, project submittals, and operational requirements for project conformity and quality control.
Here, the commissioning provider implements their requirements into the purchase orders approved by the project manager and construction manager. This stage involves the rest of the commissioning team installing components, systems, quality control inspections, and record maintenance of functional testing.
As mentioned earlier, the primary purpose of commissioning is to produce high-quality building projects, so at the construction stage, the key deliverable of a Cx agent is to monitor progress and ensure each process is conducted according to set standards. This feedback is then captured in progress reports and recorded in the quality management software.
What makes or breaks a construction project is how teams collaborate and communicate throughout this process. You can have great designs and well-laid-out plans, but communication ensures the project is completed in good time and within budget. Project management software improves communication and reduces collaboration inefficiencies.
The best practice is to involve your commissioning provider to assess their effectiveness against the results during this phase. This exercise ensures that deficiencies are corrected quickly, and the final commissioning report accurately captures all records for accurate closeout and documentation handover.
Commissioning services do not have to be applied for new projects only. There are different models depending on the type of project. They are:
Applies to projects that started without an initial commissioning plan. Many projects that did not undergo the commissioning process end with errors and deficiencies, forcing companies to reverse-engineer results into the OPRs. The main objective in retro-commissioning is to identify the mistakes, flaws, and non-compliant processes and develop corrective, low-cost solutions.
This model applies commissioning to a previously commissioned project. Existing building systems often require adjustments due to advanced technology, sustainability advancements, and the changing needs of owners and tenants. It's recommended that commissioning be applied to maintain quality and reduce operating costs.
Continuous commissioning ensures projects continuously adhere to quality standards, an ever-changing regulatory landscape, and technology advancement. This constant exercise also ensures a project stays close to the Owner's Project Requirements regardless of time and the team assigned to the project.
To achieve consistent quality and compliance, apply these commissioning best practices:
Proper documentation underpins the entire commissioning process.
The main document is the Operations and Maintenance (O&M) Manual, which includes:
Thorough documentation keeps your project compliant and your team accountable at every phase.
At FTQ360, we understand how challenging it is to manage and control commissioning projects, document inspections, performance data, technical tests, and resolve deficiencies, all while holding multiple teams accountable. That’s why we created a commissioning platform to improve and streamline your commissioning process and achieve first-time quality.

Commissioning is a quality-focused process that ensures building systems meet the owner’s performance, safety, and efficiency requirements from design to handover.
Retro-commissioning (for existing buildings), re-commissioning (re-establishing performance), and continuous commissioning (ongoing optimization).
It reduces change orders, improves building performance, ensures compliance, and enhances safety and energy efficiency.
Ideally in the planning phase, so Owner’s Project Requirements influence design, procurement, and construction.
A qualified professional or firm responsible for managing, coordinating, and validating commissioning activities.
The correct spelling is commissioning. “Commisioning” (with one ‘s’) is a common misspelling.
