Project Size:  120,000 SF, consisting of 6 buildings

Project Cost:  $19.5 Million

End Date:   2009

Owner:  United States Army Corp of Engineers - US ACOE

Scope of Work:  TMCx was hired to perform LEED Fundamental to verify and document that the building systems functioned in compliance with the design criteria set forth in the project specifications.  Our commissioning activities began somewhat late in the construction phase of the project, and did not include involvement in design or submittal evaluation. 

The mechanical systems in these building are primarily comprised of various single speed air handling units with electric heat and direct expansion (DX) condensing units, as well as Variable Air Volume (VAV) air handling and terminal units with electric reheat.

Results:   Since much of the mechanical equipment and ductwork was already installed, our initial site visit objective was to identify any issues that would affect operation, maintenance or access to the equipment. This created 3 RFI’s, including a maintenance (access) problem for VAV-8 due to the ductwork of the AHU in that mechanical room. This resulted in the relocation of the VAV unit, making access easier for the staff.

During functional testing for the Variable Air Volume terminal units (VAV boxes), TMCx noticed that the airflow setpoints for heating mode seemed higher than expected.  These boxes provide one to three stages of electric reheat, and it is important to provide adequate airflow to avoid overheating and safety lockout from occurring.  However, too much airflow will result in overloading the capacity of the heat strips, inadequate reheat for a particular zone and wasted energy at both the Air Handling Unit and the VAV boxes.  The engineer, controls contractor and TestMarc worked together to come up with lower and more appropriate reheat airflow setpoints which were tested to ensure better and more efficient operation.

Project Description: The new K-8 Pendergast Elementary School is currently has 750 students. Before developing the conceptual design, extensive programming meetings were held with the community and staff of the school district. The main vision of the project was to design a school building as a learning and teaching tool, with the buildings and the central courtyards as learning environments where students interact hands-on with various aspects of the building systems (cool tower, sun dial, electricity used, air flow, etc.). This green school has state-of-the-art energy management systems and it is projected that utility and maintenance/operational cost savings will be between 25-30% more than a traditional school.

Project Size:  78,000 square feet   

Project Cost:  $10.3 Million

Owner:  The Pendergast School District

Scope of Work:  TMCx was hired to perform LEED Fundamental and Enhanced Cx and to verify and document that the building systems functioned in compliance with the design criteria set forth in the project specifications.  The main pieces of equipment were  packaged AC Units, Day lighting, photovoltaics.

Results:   The HVAC issues were relatively minor. Most of the issues encountered included the day lighting controls, the zoning setup, and calibration. The issues that were identified over the project’s duration ultimately provided easier maintenance, which means less headaches for the owner down the line and a quicker response by the O&M Staff to complaints.

Project Size:  420,000 square feet 

Project Cost:  $200 Million

Owner:  The Gila River Indian Community

Scope of Work:  TMCx was hired to verify and document that the Mechanical/HVAC, Electrical, Plumbing, and Life Safety building systems function in compliance with the design criteria set forth in the project specifications. Functional testing of the project was completed in September 2010. The instillation of the mechanical equipment and systems had already started by the time TMCx was contracted. Due to the condensed project schedule, most systems had to be installed with contractors working multiple shifts. Several pre-functional site walks were performed to observe equipment installation with a focus on access for future service and or repairs.

Results:   There were several key issues that were identified over the project’s duration that ultimately provided a safer, more energy efficient building, saving the owner additional contractor returns and cost. Examples include:  AHU-1 had an exterior cabinet leakage, AHU – 2 had return air path issues resulting in significant space comfort issues and the VAV boxes serving the Theater did not originally have access above the ceiling for the O&M staff.   There is a specific operation of the fire alarm system and its interface with the air handling systems that was also verified during functional testing. This operation is a single use vent mode that is manually enabled by the fire department through the fire alarm panel. The vent mode is intended to use the air handler return fans to exhaust or remove any residual smoke from the casino or back of house areas after a fire has been extinguished. This action, when combined with opening the exterior doors, would allow for fresh air to be drawn into the building(s) and exhausted out through the air handlers to provide a more comfortable environment for cleanup and safety personnel. Due to the size of these fans and their capabilities a test was performed to establish a setpoint that would limit the amount of air being drawn by the fans so no further property damage would be caused and to protect the cleanup and safety personnel using the exterior doorways.
