Optimize performance. Maximize value.
For building owners, those goals sound simple enough. In practice, they depend on dozens of systems working together behind the scenes, from heating and cooling to lighting controls and automation.
A building can look exceptional on opening day and still struggle with comfort issues, unnecessary energy use or ongoing maintenance headaches a few months later. That’s why commissioning matters.
A commissioning agent serves as an advocate for the owner throughout planning, design and construction. Their role is to verify that building systems are designed, installed and operating the way they were intended before the project is turned over.
In other words, commissioning helps ensure the building performs the way the owner expects it to.
More Than a Final Inspection
Some owners assume commissioning happens near the end of construction. In reality, the biggest benefits come when the commissioning agent is involved from the beginning.
Early participation allows the commissioning team to review system designs, identify potential issues and work alongside architects, engineers and contractors before problems become expensive to fix.
That proactive approach often leads to:
- Reduced incidence of unrealized energy efficiencies
- Consistent climate control for improved occupant comfort
- Reduced life-cycle costs and fewer service calls
- Better communication between project stakeholders
- Greater owner confidence through third-party verification
It also creates opportunities for owner and operator training throughout planning, design and construction, helping facility teams better understand the systems they will eventually manage.
Bringing All the Pieces Together
One of the biggest misconceptions about commissioning is that it only involves checking whether equipment turns on and off properly. In reality, commissioning is about making sure all of the individual systems and trades are working together as one complete building system.
Take a typical air handling unit, for example.
The mechanical engineer determines what the unit needs to do based on the building’s heating and cooling demands. The mechanical contractor installs the equipment. The electrical contractor provides power to the unit. The controls contractor programs the system to operate according to the design intent. Then the test and balance contractor fine-tunes airflow and performance so the space conditions properly.
That is five different trades, often working independently, all contributing to the operation of one piece of equipment.
The commissioning agent’s job is to step back and verify that the coordination between all of those parties actually happened correctly.
- Was the equipment installed the way it was designed?
- Is the electrical service correct?
- Do the controls match the intended sequence of operations?
- Has the system been adjusted to perform the way the engineer intended?
Without commissioning, those questions are not always fully answered before the building is turned over to the owner.
Turning Design Intent Into Real-World Performance
Even well-designed buildings can experience operational issues if systems are not properly coordinated and tested. Heating and cooling systems may compete with each other. Lighting controls may not function as intended. Automation settings may not align with how the building is actually used.
Commissioning helps bridge the gap between design intent and day-to-day performance.
On a recent public library renovation and expansion project, commissioning support helped verify that the building’s systems aligned with the facility’s long-term operational goals. The renovated space included flexible meeting rooms, technology areas, collaborative spaces and expanded community gathering areas, all designed to support a modern visitor experience.
As commissioning agent, Kerr-Greulich Engineers tested variable refrigerant systems, dedicated outside air units and lighting controls to ensure systems would operate efficiently and respond correctly to automated controls. The team also reviewed programming settings to maximize energy efficiency while improving occupant comfort throughout the building.
In one area, testing identified opportunities to improve heating performance and reduce temperature stratification at the roof. Adjustments made during commissioning helped create a more comfortable environment for staff and visitors while reducing wasted energy.
Perhaps most importantly, the commissioning process included collaboration with the building design team and library staff to fine-tune system settings based on how the building would actually be used day to day.
That level of coordination can make a major difference once a building becomes occupied.
Peace of Mind for Building Owners
Most building owners are not experts in mechanical, electrical and plumbing systems, nor should they have to be.
At the end of a project, owners are often asked to trust that every contractor installed and programmed systems correctly. Commissioning provides an added layer of confidence because someone independent from the construction trades has reviewed the systems and verified that they are operating as intended.
That third-party verification can be especially valuable on projects with complex building systems or aggressive energy-efficiency goals.
For owners, commissioning helps reduce uncertainty. It provides reassurance that the building they invested in has been tested, evaluated and prepared to support occupants from day one.
Protecting the Owner’s Investment
Buildings are long-term investments, and operational performance matters long after construction wraps up.
A properly commissioned building is typically easier to maintain, more energy efficient and better prepared to support occupants over time. Small operational problems caught early can prevent years of unnecessary service calls, comfort complaints and utility costs.
Commissioning also provides owners with clearer documentation, system testing records and training resources that can support facility operations well into the future.
For owners, that means fewer surprises after move-in and greater confidence that systems are performing as promised.
Why Owners Choose Kerr-Greulich Engineers
Kerr-Greulich Engineers has been designing and commissioning building systems for more than 40 years, long before energy codes made commissioning a requirement on many projects.
Because KGE is a full-service engineering firm, the commissioning team brings practical design experience to every project. That broader understanding allows the team to identify and solve issues that extend beyond commissioning alone.
The Louisville-based team also provides responsive local support, often able to be on site as soon as the next day without the added cost or delay associated with out-of-town consultants.
Over the years, building owners have trusted Kerr-Greulich Engineers to commission more than $350 million in building construction projects.
Building Confidence From Day One
At its core, commissioning is about reducing uncertainty.
Owners invest significant time and resources into their buildings. Commissioning helps protect that investment by verifying that critical systems will function properly, operate efficiently and support the needs of the people who use the space every day.
When commissioning is integrated into the architectural and engineering team from the start, owners gain more than an additional consultant. They gain a solutions-focused partner dedicated to helping the building perform at its best from day one and for years to come.
