Our commissioning department consists of certified commissioning authorities and registered professional engineers. Our experience ranges from large new construction projects to relatively small renovations. At any one time, CTI has a roster of 10 to 15 active commissioning projects.
Your facility will function more efficiently and have fewer problems after the commissioning process is complete. CTI’s thorough approach proves cost effective for the contractor by reducing call-backs during the warranty period and ensures that the building owner receives a high performance, low maintenance, and low operating cost facility.
The Commissioning Process
CTI tailors the commissioning process to our clients’ needs, providing services ranging from simple operational checks to complete integration with the design team on new construction projects. CTI’s commissioning approach relies on forming a cooperative commissioning team involving the building owner, design team, and the construction team. The result is a fully functional system that can be properly operated and maintained throughout the life of the building.
Commissioning a New Building
Today’s buildings are comprised of complex, integrated and sustainable building systems. To ensure that these systems meet their high performance goals, it is essential that a comprehensive verification process be used throughout the building design and construction process. This process is building commissioning. Advantages include:
- $30 billion in potential annual energy savings and avoidance of 340 million tons of emissions every year in the commercial real-estate inventory.
- “Arguably the single-most cost-effective strategy for reducing energy, costs, and greenhouse gas emis¬sions in buildings today.”
- Payback time of 4.2 years for new buildings and 1.1 years for existing buildings.
- Non-energy benefits (finding construction and design deficiencies) are extensive and by themselves often offset all or part of the commissioning cost

Commissioning an Existing Building
Existing Building Commissioning (EBCx) performed on existing buildings. EBCx includes Retrocommissioning (RCx) that applies the commissioning process to buildings that have not previously undergone commissioning, Monitoring Based Commissioning (MBCx) that supplements the commissioning process by including ongoing monitoring, Recommissioning (ReCx) that periodically re-implements the commissioning process, and Ongoing Commissioning (OCx) that applies commissioning-related process activities on a continuous basis. These are the systematic process of identifying low-cost operational and maintenance improvements to buildings. Whether you have pre-existing conditions or issues that just arrived, CTI can determine what they are and develop a cost effective way to resolve them. Advantages of Existing Building Commissioning (EBCx) include the following:
- Reduced Energy Consumption and Costs
- Reduced Environmental Impact
- Increased Net Operating Income
- Improved Equipment Performance
- Improved Occupant Comfort
- Improved Indoor Environmental Quality
The Commissioning Process for an Existing Building
CTI begins by examining your facility including all energy consumption systems. Next we perform an energy audit for the entire building. The results of this audit are used to determine which systems are not functioning as efficiently as possible. Finally, we make recommendations for improving the underperforming systems. The recommendations can be as simple as modifying a controls program or as complex as replacing an entire HVAC system. Whatever the case may be, we put our knowledge and skills to work for you.
