Park Hall is an academic building on SUNY Oswego’s campus that houses the School of Education Dean’s Office, Department of Technology, Educational Administration, Vocational Teacher Preparation, and the School of Educational Field Placement.
As part of the renovation in 2012, Bergmann Engineers planned to use demand control ventilation to control energy expenses associated with heating and cooling outside air quantities in various class rooms and lecture halls. With over 23 spaces equipped with VAV boxes they recognized using a centralized demand control ventilation platform with one high quality CO2 sensor vs.23 single location CO2 sensors would result in both a more accurate signal to the Trane building automation system, and reduced calibration costs over the building life cycle. This means greater savings to the campus and less expense than a conventional single location CO2 sensing platform.
The Aircuity OptiNet system senses carbon dioxide (CO2) in the 23 classrooms and lecture halls to optimize the cubic feet per minute of outside (ventilation) air. The more people in the space, the more CO2 is generated and sensed. The OptiNet system signals the building automation system to proportionately adjust outside air CFM for each space. Why heat or cool outside air when it is not needed? ASHRAE guidelines require a differential measurement for outside and inside CO2 levels. Aircuity’s approach uses a single sensor to test both indoor CO2 and outside air, providing a true and accurate CO2 differential measurement.
