When Is Commissioning Required for Your Project?

  • Are you planning a construction project in Illinois?
  • Does your cooling system exceed 40 tons of capacity?
  • Is your heating system rated over 600 MBh?
  • Are you constructing or retrofitting a large-scale commercial building?
  • Do you manage facilities with high energy demands, such as hospitals, schools, or data centers?
  • Are you upgrading HVAC systems in a building with complex mechanical requirements?
  • Are you a contractor or engineer tasked with ensuring code compliance for a multi-tenant property?

If you answered "yes" to any of these questions, the Illinois Energy Conservation Code (IECC) requires you to complete third-party commissioning to comply with the latest energy standards. Let’s break it down in a way that’s easy to understand.


What Does the 2021 IECC Mean for You?

As of January 1, 2024, Illinois has adopted the 2021 IECC, ushering in stricter energy efficiency requirements for mechanical systems in commercial buildings. But compliance doesn’t have to be complicated. Whether you're a contractor, building owner, engineer, or facilities manager, understanding these regulations can save you time, money, and potential headaches down the road.

Here are the basics:

When Is Third-Party Commissioning Required?

  • Cooling Systems: If the total mechanical cooling capacity of the equipment being installed exceeds 480,000 Btu/h (140.7 kW), which is equivalent to 40 tons.

  • Heating Systems: If the combined input capacity of the service water-heating and space-heating equipment exceeds 600,000 Btu/h (175.8 kW).

What Is the Purpose of Commissioning?

Commissioning ensures that your mechanical systems are designed, installed, and functioning as intended. It’s not just about checking a box for compliance; it’s about making sure your building operates efficiently and effectively from day one.

Who Needs to Be Involved?

A qualified third-party commissioning provider (like us!) will work with your team to validate system performance and document compliance for code officials.


Why Partner with an Expert?

Third-party commissioning is an investment in your project’s success. Here’s what it delivers:

  • Peace of Mind: Knowing your systems meet the latest energy codes and perform as expected.
  • Energy Savings: A well-commissioned system reduces operational costs and maximizes efficiency.
  • Problem Prevention: Identifying and resolving potential issues during construction avoids costly fixes later.
