Total Building Commissioning for University
A university in Michigan set out to construct a new state-of-the-art science building and required total building Commissioning (Cx). This new structure would be complete with high-end equipment to track plants in their growing rooms with scientists who understood what their critical environments needed. Temperature sensors and expensive microscopes were taken into consideration during design. Their environment was critical to their work which is why Synergy was hired as the Commissioning Agent for the University.
The university embodies the belief that commissioning should be part of every project as they follow the FGI guidelines, which require a Commissioning Plan. Synergy was hired to do Enhanced Commissioning and Fundamental Commissioning. These services define the Owners Project Requirements early on in the project and are verified during design, construction, and occupancy, and operations phases to ensure a successful building is turned over.
The Plan
In creating the Owners Project Requirement (OPR) for the project, the university outlined some aggressive energy efficiency goals. Typically, a science building with a wide assortment of high-end equipment can be an energy drain. Setting a new standard of energy efficiency with this LEED Certified building, the owners knew this facility would be complex and had to decide on aggressive set-back temperatures. Heating and cooling set-points required occupancy sensors in order to drive the desired energy efficiency.
Synergy outlined and followed the standard Commissioning Plan which takes the client’s facility and their teams through three main phases: Design, Construction, and Occupancy and Operations. Synergy was involved in the Design phase with the OPR helping the client understand the temperature set-points. The construction phase involved static testing, installation inspections, start-ups and testing, adjusting and balancing to make sure the systems worked properly. After that, functional testing and training were held with the owner’s Building Automation System (BAS) and operations team.
During the final Occupancy and Operations phase, it is recommended for end-users to understand how the space is to be used correctly. When the building was complete, Synergy followed up with a bi-weekly meeting, then monthly meetings with the Facility Managers. This enabled continued discussion around the building operations. Open and ongoing communication aids users in understanding that the expectations of the building are met and full awareness of its internal operations are understood.

Deployment Arrangement
When the building opened the biggest experts on the construction deployment were leaving the facility as their job was complete. Synergy acts as a bridge between construction and operations and leads training with facility teams. This particular training involved commissioning and system-level training. During this training, the client designated a spot in their mechanical room for digital files, O&M and document storage. It was incredibly valuable to the facility team to know where they could locate all the vital documents for the building, including the systems manual. This manual listed all the systems within the facility and how they integrated with each other internally; including the procedures, tasks, and periods of maintenance.
In creating energy efficiency, the university widely employed chilled beams in the design. This enabled the science labs to have individual environments within the same air-handler, but allowed for each room to have a set temperature. With such a large installation of chilled beams, without proper training, the facility teams would have had a larger challenge in understanding how the building operated. The control parameters and technology were vastly different than what they had used in their other laboratories.
