Duct Leakage A New Solution to a Hidden Problem

May 22, 2014
1 p.m. – 2 p.m.
Eastern Daylight Time


Duct leakage has a significant impact on laboratory performance, energy usage, and air quality. It is estimated that many building in the United States and Canada lose an average of 30% or more of treated air through duct leaks. Laboratories are particularly at risk from the effects of duct leakage. The high demand for tight temperature and humidity control and contamination prevention make the air distribution a key element of every successful laboratory. 

Until recently duct leakage in existing laboratories has been marginally addressed because there was no comprehensive and practical solution. Recent developments in duct sealing technology now allow facility engineers to cost effectively eliminate almost all duct leakage. This presentation will explore the current and developing standards for duct leakage, and best practices for reducing duct leakage in both new and existing laboratories.

By attending this session:

  • Participants will learn how to quantify the energy savings potential from low leakage duct air distribution systems in their laboratories
  • Participants will learn the current standards for specifying duct leakage.
  • Participants will learn to compare the current duct leakage standards to laboratory requirements for air changes per hour, pressurization and air flow.
  • Participants will understand the pros and cons of the various methods for sealing ductwork.
