Case Study

SUNY Plattsburgh

Hudson Hall on the SUNY Plattsburgh campus is one of two main science buildings. By implementing a laboratory demand control ventilation system, air change rates were reduced from 6 (with a few spaces at 7) to a baseline of 3 and 4 ACH, increasing when additional fresh air is needed.  Optimizing ventilation also addressed an issue with moisture in the labs. Originally, the chillers in the building were not keeping up with the cooling requirements, which caused a moisture issue with the microscopes. With the ventilation rates matching the current needs of the space, and generally less air to cool, SUNY Plattsburgh’s Environmental Health & Safety department confirmed that the problem was eliminated. This solution also helped to reduce the university’s deferred maintenance backlog by identifying several faulty controllers in the building. SUNY Plattsburgh was able to save energy in one of its most energy intensive and critical safety environments on campus, while receiving better indoor environmental quality and reducing deferred maintenance along the way. The energy reduction in Hudson Hall grabbed the attention of the New York State Energy Manager (NYEM), who took note of the reduction in the building at the meter level.

The graph above shows an initial drop in airflows at the end of May, however, the target air flows were not being achieved. This prompted a service  call and it was discovered this lab (and two others) had a broken actuator. The actuators were repaired and target CFM levels were achieved on June 16th (arrow)
