Georgia Functional Performance Testing FAQs

  • What is Commissioning?
    • Commissioning (or Functional Performance Testing as amended by the Georgia Amendments) is defined by ASHRAE as “A quality-focused process for enhancing the delivery of a project. The process focuses on verifying and documenting that the facility and all of its systems and assemblies are planned, designed, installed, tested, operated, and maintained to meet the Owner’s Project Requirements”.  While there is always involvement during the testing and balancing of equipment, fully integrated commissioning can start as early in the project as conceptual phase and can end well after turnover/occupancy.
  • Where can I find the new Code Requirements for Commissioning if I want to read more about it?
    • 2015 International Energy Conservation Code (IECC) Section C408 – System Commissioning
    • GA International Energy Conservation Code Supplements and Amendments 2020
  • What date will this new code take effect, requiring commissioning services for all new buildings?
    • The effective date is January 1st, 2020. All projects which have not received approval by this date will be required to comply with 2015 International Energy Conservation Code and 2018 International Building Codes with Georgia Supplements and Amendments 2020.
  • Who can perform the commissioning services?
    • The commissioning must be completed by a registered design professional or approved agency.
  • What is the responsibility of the engineer of record related to these services? What deliverables can be expected from commissioning?
    • The EOR is responsible for ensuring that the construction document notes indicate provisions for commissioning or functional performance testing and completion requirements, and are permitted to refer to specifications for further requirements.
    • The deliverable from the commissioning process is the issuance of the preliminary commissioning report and the completion of the final commissioning report as stated in C408 of the 2015 International Energy Conservation Code. Note that the building shall not be considered acceptable for final inspection until the code official has received a letter from the building owner stating that the initial commissioning report has been received.
  • Is the commissioning effort restricted to the HVAC system of the building?
    • Per the 2015 IECC, the commissioning applies to three areas:
      • Mechanical
      • Service Water Heating
      • Lighting Controls
  • What types of tasks are included in the commissioning effort?
    • Commissioning includes functional testing, system and equipment balancing, and demonstration of compliance with design intent.
  • Are certain types of projects exempt from this requirement?
    • Per IECC C408.2, buildings with mechanical systems less than 480,000 Btuh cooling capacity and 600,000 Btuh combined service water-heating and space-heating capacity.
    • Systems that serve individual dwelling and sleeping units.
  • What types of tasks are included in the commissioning effort?
    • Commissioning includes functional testing, system and equipment balancing, and demonstration of compliance with design intent.
  • What fees can be expected in conjunction with commissioning?
    • General rules of thumb dictate that commissioning fees will be in the neighborhood of $1.00 to $2.00 per square foot, but there can be great variations depending on complexity, size, and use of the building. McVeigh & Mangum will be happy to provide a quote for any building requiring commissioning services.
  • Can McVeigh & Mangum Engineering, Inc. assist with commissioning, even if they did not do the initial design work?
    • Yes, MME can provide commissioning services for buildings regardless of who the EOR is on the permit sets.
