CalGreen Commissioning Services

We provide CalGreen Commissioning Services for projects throughout the State of California.

CalGreen Commissioning is the professional practice that ensures buildings are delivered according to the Owner’s Project Requirements and in accordance with the design documents. Buildings that are properly commissioned typically have fewer change orders, tend to be more energy efficient, and have lower operation and maintenance cost.

If your building is over 10,000 square feet, both the CalGreen Code and the California Energy Code (commonly referred to as Title 24) require the project to be commissioned. What is most important to note is that the commissioning required by these codes is not as extensive as some industry commissioning standards. We often see commissioning agents applying higher standards than is actually required by the California Building Code. While this may be beneficial on some projects, it also translates into higher costs for the owner.

We have experience in a wide range of commissioning projects including:

  • Wineries and Breweries
  • Storage Facilities
  • Grocery Stores (see our linked article)
  • Retail Stores
  • Warehouses
  • Mixed Use Residential and Commercial Projects
  • Office Buildings
  • Hotels and Motels
  • Sports Facilities and Gyms

At CalGreen Energy Services we limit the commissioning effort to that which is specifically mandated by the code. This helps keep our fees low, and the construction costs lower. Our simplified commissioning process will minimize the work required by your subcontractors while ensuring that critical components of your HVAC, Plumbing and Lighting Control systems are operating as designed.

Systems Requiring Commissioning

The CalGreen and California Energy Code require the following systems to be commissioned:

2022 California Energy Code

  • Heating, Ventilating and Air Conditioning systems and Controls
  • Indoor Lighting Systems and Controls
  • Water Heating Systems
  • Landscape Irrigation Controls
  • Windows and Doors per CEC Section 110.
  • Building Insulation per CEC Section 110.

Permit Submittal

For your permit submittal you will need to provide the following documents or you risk being rejected a permit intake:

  • The Owner’s Project Requirements report.
  • The Basis of Design report.
  • The Commissioning Plan.

CalGreen Energy Services can author these documents and have them ready for your permit submittal. This is another area where understanding the specific requirements of the California Building Code is critical to your project. The California code requirements are less stringent than some industry standards such as the LEED reporting requirements. We have the knowledge and experience to minimize this effort and ensure your commissioning process runs smoothly.

CalGreen Commissioning and the Construction Process

Commissioning Meeting

The basic steps of the construction process for our CalGreen commissioning services are:

  • Lead and document the Design Review Kick-off Meeting.
  • Maintain, and update as required, the Commissioning Plan.
  • Review of submittals, O&M manuals, and Requests for Information (RFIs) for affected systems including testing and balancing reports.
  • Generate pre-function installation checklists and field verify.
  • Author functional performance testing with subsequent reports.
  • Maintain an Issues Log, where applicable.
  • Provide a finalized commissioning report for affected systems

A commissioning agent must work closely and communicate well with your construction team. At CalGreen Energy Services we have been involved in the construction of everything from single family homes to billion-dollar Kaiser Hospital projects. We understand the importance of developing a positive relationship with your contractor to minimize the impact of the commissioning process.

More Information on Commissioning

Our website contains a number of informative articles on building commissioning in California.

For the latest updates take a look at our post Commissioning for the 2022 CalGreen Code.

Title 24, also known as the California Energy Code, also requires building commissioning for nonresidential projects over 10,000 square feet. However, the Calgreen and Title 24 commissioning requirements are integrated into a single process. For a detailed explanation on this, see our article, Title 24 Commissioning.

For an in-depth description on the commissioning process see our post, CalGreen Commissioning.
