Photo: Brad CochranBrad Cochran has over 25 years of experience conducting wind tunnel and numerical modeling assessments related to laboratory exhaust design. He is a registered Professional Engineer with the state of Colorado; serves on the ASSE Z9.5 Laboratory Ventilation sub-committee; primary author of Chapter 9 – Exhaust Stack Design in the 2015 ASHRAE Laboratory Design Guide, and is the current chair of the ASHRAE TC-9.10 Laboratory Ventilation Technical Committee. He is also the lead author on the 2011 edition of the Labs21 Best Practice Guide "Modeling Exhaust Dispersion for Specifying Acceptable Exhaust/Intake Design". Mr. Cochran also served on the AMCA Induced Flow Fan CRP Committee that developed AMCA Standard 260-07, "Laboratory Methods of Testing Induced Flow Fans for Rating."

In 2011, Mr. Cochran received an individual Go Beyond Award from I2SL.

During the past decade, Mr. Cochran has focused on defining new design and control techniques to minimize the energy requirements for laboratory exhaust systems. In 2005, Mr. Cochran developed the first laboratory exhaust system that utilized local wind data to minimize exhaust fan horsepower requirements, and in 2008 introduced the concept of monitoring chemical constituents within the exhaust manifold to reduce volume flow rates when measured VOC concentrations are below an established threshold. Since then, Mr. Cochran has implemented VAV controls in over 150 laboratory exhaust systems throughout the U.S., Canada, and the U.K.

Mr. Cochran has authored and presented several papers on the subject of energy-efficient laboratory exhaust design for Sustainable Labs Canada (SL-Can); S-Labs (UK), DELabCon (India), Australasian Laboratory Management Association (ALMA), the American Society of Heating, Refrigerating and Air-Conditioning Engineers Inc. (ASHRAE), I2SL, R&D Magazine, Lab Manager Magazine, LabWize, the International Facility Management Association, Air Movement and Control Association International, Inc., and the Air and Waste Management Association.
