Topic: Guidance 36: Best in Class HVAC Control Sequence

Presented By:  Steven Taylor of Taylor Engineering

4:00 pm - 5:30 pm

Presentation:  Guidance 36: Best in Class HVAC Control Sequence

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.”
