Building Commissioning Services
At KOW Building Consultants, our building commissioning services help owners, developers, architects, contractors, and lenders verify that building systems perform the way they were intended to perform.
From early design review through turnover and occupancy, building commissioning is a structured quality assurance process focused on verifying and documenting that systems work, materials are installed correctly, and overall project performance aligns with the Owner’s Project Requirements.
As part of our broader sustainability services and full building consulting services, our commissioning team supports new construction, substantial rehabilitation, electrification projects, and existing building optimization.

What Is Building Commissioning?
Building commissioning is a systematic process used to confirm that a facility’s systems are designed, installed, tested, and capable of being operated and maintained according to the owner’s goals.
If someone asks, “what is building commissioning?”, the simplest answer is this: it is a formal process for making sure a building actually performs the way it was designed to perform.
A quality commissioning process typically includes:
-
Owner’s Project Requirements (OPR) review
-
Basis of Design (BOD) review
-
Design and submittal review
-
Installation observation during construction
-
Pre-functional and functional performance testing
-
Issue tracking and deficiency resolution
-
Training and turnover support for operations staff
-
Final commissioning documentation and reports
Why Building Commissioning Matters
Buildings that are not properly commissioned often experience:
-
Higher-than-expected energy use
-
Poor ventilation and uneven temperatures
-
Comfort complaints from residents or tenants
-
Controls that do not match design intent
-
Premature equipment wear
-
Higher operating and maintenance costs
-
Difficult turnover to facility management teams
That is why building commissioning services matter. A structured commissioning process helps owners and project teams catch issues before they become long-term operating problems. It also helps preserve the value of related planning work such as feasibility studies, integrated physical needs assessments, and capital needs assessments.
For projects in New York, commissioning can also support broader compliance and energy performance goals tied to decarbonization, electrification, and local energy code requirements.

Types of Building Commissioning Services
New Construction Building Commissioning
For new construction and major gut rehabilitation projects, our commissioning team works throughout the design and construction process to verify that systems are installed correctly and perform according to design intent.
This typically includes:
-
Early design coordination
-
Review of mechanical, electrical, plumbing, and controls design
-
Construction observation and issue tracking
-
Functional testing of systems before turnover
-
Final commissioning report and owner documentation
This form of commissioning a building is especially useful for multifamily, mixed-use, affordable housing, and commercial projects where system coordination can directly impact operations, comfort, and utility costs.
Existing Building Commissioning / Retro-Commissioning
Not every property was commissioned at turnover, and even well-built facilities can drift away from optimal performance over time. Existing building commissioning and retro-commissioning focus on restoring performance in occupied properties.
This work often identifies:
-
Controls issues
-
Sequence-of-operations problems
-
Airflow and balancing deficiencies
-
Boiler, ventilation, or domestic hot water inefficiencies
-
Missed opportunities to reduce energy use without major replacement
This can pair naturally with property condition assessment services and broader construction risk management consulting when owners are evaluating capital improvements or repositioning strategies.
Ongoing Commissioning and Monitoring-Based Commissioning
Some buildings need more than one round of testing. Ongoing commissioning and monitoring-based commissioning help owners maintain performance after occupancy through periodic review, trend analysis, and operational tuning.
These services are valuable for:
-
Buildings with advanced controls or automation
-
Properties with repeated comfort complaints
-
Facilities trying to improve benchmarking performance
-
Owners seeking long-term energy savings and operational consistency
For buildings going through larger energy planning efforts, this work can support findings from Local Law 97 consulting and related code-driven upgrades.
Building Enclosure Commissioning / Building Envelope Commissioning
Many owners focus only on mechanical systems, but building enclosure commissioning and building envelope commissioning play a major role in long-term performance. If the envelope is not performing properly, even the best HVAC design can struggle.
Envelope-related commissioning may include review of:
-
Air barrier continuity
-
Waterproofing details
-
Roof transitions
-
Window and curtain wall interfaces
-
Moisture management details
-
Thermal bridging concerns
This is especially important for high-performance buildings, affordable housing, and projects targeting durability, indoor air quality, and lower heating and cooling loads.

Commissioning Support Across Project Types
KOWBC provides building commissioning services for a wide range of property types and project goals, including:
Multifamily and Affordable Housing
Commissioning can help improve resident comfort, reduce operating costs, and support green building or agency requirements.
High-Performance and Electrification Projects
Commissioning is critical when buildings transition to heat pumps, advanced controls, ventilation upgrades, and lower-carbon systems.
Rehabilitation and Repositioning Projects
When owners are modernizing older buildings, commissioning provides added confidence that new systems will work as intended.
Code-Driven and Compliance-Focused Projects
For New York projects dealing with evolving energy rules, our team can help connect commissioning to broader compliance strategies. Related reading includes how to stay compliant with NYC Local Laws 87 and 97, the LL87 filing deadline update, and our overview of the 2025 New York Energy Code.

Building Commissioning FAQs
What is building commissioning?
Building commissioning is the process of verifying and documenting that building systems are designed, installed, tested, and capable of operating according to the owner’s goals and the project’s design intent.
What does commissioning a building involve?
Commissioning a building usually involves design review, installation verification, functional testing, issue tracking, documentation, and support for turnover to operations staff.
What is the difference between building commissioning and existing building commissioning?
Traditional commissioning usually refers to new construction or major rehabilitation. Existing building commissioning focuses on improving the performance of buildings that are already occupied or operating.
Do you provide building envelope commissioning?
Yes. KOWBC can support both building enclosure commissioning and building envelope commissioning where the performance of walls, windows, roofing, waterproofing, and air barriers is critical to long-term building durability and efficiency.
When should building commissioning start?
The best time to start is early. Bringing a commissioning provider in during design helps identify issues before they become construction or turnover problems.
How does commissioning support energy performance?
Commissioning helps make sure systems actually function the way they were designed to function. That can reduce wasted energy, improve ventilation, lower operating costs, and support better indoor environmental quality.
Why choose KOWBC over other building commissioning companies?
Among building commissioning companies, KOWBC stands out by combining field experience, sustainability expertise, due diligence knowledge, and a practical understanding of how buildings are financed, renovated, and operated in the real world.
