Ongoing Commissioning

An ongoing program tailored to meet facility operational requirements and sustainability goals. Successful programs may be initiated any time during the life of a building: immediately after construction of a commissioned building or years later in a building that was never commissioned. ​

Typical Objectives of Ongoing Commissioning

  • Bring equipment to its proper operational state​
  • Verify that facility and its systems meet the Owner’s requirements​
  • Improved building performance resulting in reduced energy usage and operating costs​
  • Identify and resolve building system operation, control, and maintenance problems​
  • Reduce or eliminate occupant complaints and increase tenant satisfaction​
  • Document system operation​
  • Identify additional Operations & Maintenance (O&M) personnel training requirements ​
  • Assist in achieving LEED Existing Building O&M certification
  • Improve the building’s ENERGY STAR rating ​

LEED v 2009

The U.S. Green Building Council (USGBC) Leadership in Energy and Environmental Design (LEED) Existing Building (EB) Operations and Maintenance (O&M) v2009 Energy and Atmosphere (EA) Credit 2.3: Existing Building Commissioning – Ongoing Commissioning provides the following definition:

Ongoing commissioning is a continuous process that methodically identifies and corrects system problems to maintain optimal building performance; it includes regular measurement and comparative analysis of building energy data over time.

Key Components

  • Ongoing Commissioning Plan: Outlines the team organization, goals, schedule, allocation of resources, and documentation requirements of the commissioning process.
  • Commissioning Issues Log: Record of the issues identified during functional performance testing that includes a detailed description, priority level, and responsible party to facilitate corrective action response.
  • Functional Performance Tests: Test forms used to verify and document HVAC and lighting equipment operation.
  • Current Facility Requirements and Building Operating Plan: Identify owner’s operating requirements such as space temperature/humidity, outside air fractions, and schedules.
  • Site Visit Reports: Overview of the work accomplished, key observations, update on testing progress, commissioning issues log, and low-no cost energy conservation opportunities identified for consideration.
