Naperville Certified Commissioning & Retro-Commissioning

When a building is initially commissioned or retro-commissioned in Naperville, it goes through an intensive quality assurance process that starts during design and continues through construction, occupancy and operation.

Comprehensive Approach

We know that testing a small percentage of Naperville building systems leaves a wide margin for failure.  Our intent is to verify and document the proper operation of all equipment through detailed test procedures and carefully followed protocol.


United Building & Energy Services Naperville commissioning agents have finished projects that cover a broad range of facility types, including schools, hospitals, data centers and office buildings.  Our agents have the knowledge and expertise to find issues and communicate efficiently with owners, design teams and Naperville contractors.

Naperville Commissioning Report

After finishing building commissioning, re-commissioning or retro-commissioning in Naperville, we prepare a final commissioning report.  The report thoroughly documents all procedures conducted by the Naperville commissioning team and results of the Naperville commissioning process. United is known for providing reports that show and describe our methods and conclusions thoroughly and accurately.

Naperville Retro-Commissioning

Also known as existing Naperville building commissioning, Naperville retro-commissioning is focused on buildings that have never undergone the commissioning process.  Like total building commissioning, retro-commissioning in Naperville ensures that an owner receives a building that operates according to its design intent and current operational requirements.

Why Naperville Retro-commission?

Buildings that haven’t been commissioned can have a host of problems, such as high energy costs, poor indoor air quality, inefficient system control, excessive maintenance and comfort control issues.

During Naperville retro-commissioning, United’s CxA team reviews current systems performance, analyzes data, creates a solution based on a plan to optimize Naperville building performance and then documents the entire process.
