In many cases, buildings lack automatic ventilation feedback and are consequently over-ventilated. This report investigates the potential energy savings for a demand control ventilation (DCV) system with centralized air quality sensors. This technology aims to maintain or improve building comfort, verify with continuous measurements that ventilation codes are satisfied, improve environmental air quality, and reduce overall energy consumption. To accomplish such a strategy the technology generally gathers the following data:
- Space Temperature
- Dew Point Temperature
- Carbon Dioxide (CO₂)
- Carbon Monoxide (CO)
- Total Volatile Organic Compounds (TVOC)
- Airborne Particulates

The main focus of this project was to document the energy savings at one particular college laboratory facility where this system was installed. The calculation strategy included a pre- and post-retrofit weather bin analysis of supply fans, exhaust fans, chilled water usage, and heating hot water usage.
