Laboratory

Exhaust systems can account for as much as 20% of a lab facility’s HVAC cost. Recent code updates allow for dynamic control of exhaust fan stack velocities, unlocking significant energy savings. Aircuity’s proven exhaust fan application reduces exhaust fan energy use by 50%, has an energy payback less than 2 years, and is approved for Eversource incentives!


How it Works

  1. Air is sampled at exhaust fan inlet
  2. Clean supply air location is sampled for differential measurement
  3. Both samples are sent to Aircuity’s Sensor Suite for analysis
  4. Measurement is compared against containment threshold
  5. Stack velocity is lowered when measured VOCs are below a defined trigger level, and fan speeds are increased when the limit is exceeded
  6. Data available on equipment performance and environmental parameters

The Benefits:

  • Significant energy savings through lower stack velocity when measured VOCs are below a defined trigger level.
  • Benefit from first cost savings by reducing the number of fans and/or size of fans required.
  • Operational and deferred maintenance benefits by modernizing fan control.

Case Study: University Health Network Exhaust Fan Application = Increased Savings

Aircuity Lab Fan Exhaust
Exhaust fan system at University Health Network

University Health Network (UHN) is Canada’s largest research hospital which operates four major hospitals and one teaching institute: Toronto Western Hospital, Toronto General Hospital, Princess Cancer Centre, Toronto Rehabilitation Institute and The Michener Institute.

Aircuity was initially installed in the Princess Margaret Cancer Research Tower in the MaRS Discovery District. The platform’s DCV control of the labs’ supply air saved approximately $800,000. UHN was happy with the savings but at the same time they knew more could be done.
