Meeting/Event Information

The 2019 version of the California Energy Commission, Title 24, will for the first time, address fan energy consumption in laboratory and factory exhaust systems. In previous versions of Title 24, Laboratory exhaust systems were exempted from the Building Energy Efficiency Standards included in Title 24. However, for 2019, the proposed changes to Part 6, Chapter 5, Section 140.9(c) now include prescriptive requirements for the maximum allowable fan energy consumption for both laboratory and factory exhaust systems with volume flow rates greater than 10,000 cfm.

During this presentation, Mr. Cochran will walk through the proposed updates to the standard; which include meeting discharge requirements from ANSI/ACGIH Z9.5-2015 – Laboratory Ventilation Standards; minimum allowable fan power per volume flow rate requirements for untreated and treated exhaust systems; and variable air volume control strategies that can be implemented when the minimum fan power allowances cannot be achieved. In addition, the presentation will also discuss upcoming changes to the Z9.5 standard, as they pertain to laboratory exhaust systems, along with their impact on the proposed Title 24 regulation.

Mr. Cochran has been on the forefront in developing and implementing safe and energy efficiency laboratory exhaust systems for the past 15 years. He has authored and presented papers on the subject at several ASHRAE national conferences and I²SL national and chapter conferences. Within the Golden Gate area, Mr. Cochran has designed and/or installed VAV laboratory control systems in well over 50 systems at local Universities and within the Biotech and Pharma industries.
