ASHRAE Guideline 36-2021, “High-Performance Sequences of Operation for HVAC Systems,” made a splash in the HVAC design and operations world this year. It is ASHRAE’s first pass at defining the “best” way to control some typical air-handling systems to meet performance requirements as efficiently as possible. This column is not about ASHRAE Guideline 36 specifically but about the value of standard sequences of operation in general.
For any building owner/operator with multiple buildings, the investment in developing and the effort in enforcing standard sequences of operation for “like” systems should result in ongoing cost savings over the life of the existing buildings and any future new buildings.
