Please register by June 8th to receive GotToMeeting invitation.


This course provides designers and operators of laboratories with wet lab exhaust systems with the proper methodology to ensure safe systems operation. Laboratory Exhaust Stacks: Safe and EnergyEfficient Design walks students through the entire design process. Energy consumption represents an important component of the course, as laboratories consume significantly more energy than a typical office building, due to laboratory ventilation systems. Training topics include how to properly locate air intakes and exhaust stacks and the various methods for applying variable-air-volume (VAV) control to minimize energy usage while avoiding adversely impacting the air quality. Attendees will calculate an appropriate concentration design criterion for a specific emission source and determine dispersion modeling techniques for particular applications.

Presented By:

Brad Cochran, P.E., Member ASHRAE, has over 25 years of experience conducting wind-tunnel, analytical, and computational fluid dynamic (CFD) modeling studies of airflow in and around man-made structures. In recent years, Cochran has led the development of new design and control techniques to minimize the energy consumption for laboratory exhaust stacks through the implementation of variable-air-volume (VAV) technologies. He has successfully designed and employed VAV exhaust systems for more than 100 laboratories throughout the United States, Canada, and the United Kingdom. He holds a B.S. and M.S. in mechanical engineering, an M.B.A., and a P.E. license (CO). Cochran is the author of the chapter on exhaust stack design in the ASHRAE Laboratory Design Guide. He serves on the ASSE Z9.5 standards committee and is Chair of ASHRAE’s TC9.10, Laboratory Systems.
