VAV Laboratory Exhaust: Turndown, Fan Selection, and Control Solutions to Save Energy and Comply With ANSI Z9.5 and CA Title 24

March 17, 2016
1 p.m. – 2 p.m.
Eastern Daylight Time


A proper and effective VAV laboratory exhaust control system to satisfy the requirements of ANSI Z 9.5 and California Title 24 begins with proper equipment and component selection. This presentation will address the impact of understanding turndown range and predominant operating range on fan selection. The design of a safe, workable, reliable, and efficient VAV lab exhaust control system must include a clear understanding of the mechanical and electrical components, their performance characteristic, and the manner in which these actually respond to control commands. This presentation will discuss these issues, with case history references.

Attendees will:

  • Understand VAV laboratory exhaust systems.
  • Learn how to optimize exhaust fan selection for VAV application.
  • Learn how the laboratory exhaust system components work and must interact in a VAV application.
  • Learn about considerations, based on experiences, for designing a safe, workable (stable), energy saving VAV lab exhaust control system that accommodate turndown, pressure maintenance, and outside exhaust dispersion requirements of ANSI Z 9.5 and California Title 24.
