Exhaust Fan Control: An Important Compliment to Lab DCV

Dan Diehl, Aircuity

Exhaust systems can account for as much as 20 percent of a lab facility's HVAC cost. Yet high exhaust stack velocities are typically maintained in excess of what is necessary. After achieving energy savings through a lab demand control ventilation (DCV) project, exhaust fan application is the final step to ensuring your lab facilities are as efficient as possible. With different approaches to this application, it is also important to learn how differential measurement and the ability to sense in the plenum versus the exhaust risers are important factors in accuracy, savings and safety. Attendees will also see a case study of this technology implemented alongside lab DCV in a public research and teaching hospital.

Learning Objectives

  • Understand how exhaust fan control can complement savings already achieved through lab DCV;
  • Know the advantages beyond just energy savings including first cost savings and the operational and deferred maintenance benefits;
  • Learn the importance of using differential measurements in exhaust fan system technology and in measuring in the containments in the plenum versus the exhaust risers; and
  • Understand the considerations for a successful implementation in your lab.
