    Please join us for our September 2020 virtual chapter meeting on Best in Class HVAC Control Sequences presented by Mr. Steve Taylor.  Your registration receipt will be emailed to you and will contain the link to access this month's meeting.   


    Standard practice for HVAC digital control systems includes creating custom control sequences for each building, often dumbed down to “keep it simple” for the building operator so much so that they are not in compliance with codes and standards such Standard 90.1 (energy) and 62.1 (ventilation).  Even with this oversimplification, the sequences are not always well programmed, debugged, and commissioned because of the one-off custom application, resulting in subpar building performance.  Guideline 36-2018, High-Performance Sequences of Operation for HVAC Systems, was created to address these issues.  It includes best-in-class control sequences that have been optimized to minimize energy use and maximize comfort and indoor air quality, that are intended to be preprogrammed and pre-debugged by control system manufacturers.  Guideline 36 has the potential to have a larger impact on building energy use than any other ASHRAE standard or guideline.  Early implementations of the sequences have shown dramatic energy savings (more than 50% reduction in boiler energy use in two buildings), all while maintaining code ventilation requirements and improving thermal comfort.  And at the same time, using the Guideline reduces costs for all parties: engineers spend less time writing sequences, local control contractors spend less time programming, commissioning agents spend less time testing, building engineers spend less time operating and maintaining, and building owners pay lower energy bills.  Meanwhile, occupants see better thermal comfort and better indoor air quality.  Once fully implemented, Guideline 36 will be a win-win-win-win-win-win for all parties.

    Mr. Steven T. Taylor, P.E.

    Steve Taylor is the principal of Taylor Engineering, Alameda, CA.  He is a registered mechanical engineer specializing in HVAC system design, control system design, indoor air quality engineering, computerized building energy analysis, and HVAC system commissioning.  Mr. Taylor graduated from Stanford University with a BS in Physics and a MS in Mechanical Engineering and has 40 years of commercial HVAC and control system design and construction experience.  He is a Fellow of the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and one of very few to have received all of ASHRAE’s top awards for technical achievement.  He was one of the primary authors of the HVAC sections of ASHRAE Standard 90.1 “Energy Conservation in New Non-residential Buildings” and California’s Title 24 Energy Standards and Ventilation Standards.  He has authored over 40 peer-reviewed ASHRAE Journal articles and technical papers.  Other ASHRAE project and technical committees that Mr. Taylor has participated in include Standard 62.1 Indoor Air Quality (chair), ASHRAE Standard 55 Thermal Comfort (member), Guideline 13 Specifying Building Automation Systems (chair), Guideline 16 Economizer Dampers (chair), TC 1.4 Controls (chair), TC 4.3 Ventilation (chair), Guideline 36 Optimized Controls (founder and chair).  He is past vice-chair of the USGBC LEED Indoor Environmental Quality Technical Advisory Group, a member of the CSU Mechanical Review Board, and a 16-year member of the IAPMO Mechanical Technical Committee administering the Uniform Mechanical Code.
