Understand ASHRAE Guideline 36 — the standardized, energy-optimizing sequences of operation for HVAC systems — and why implementing Guideline 36 can reduce HVAC energy consumption by 30% or more in commercial buildings.
ASHRAE Guideline 36, "High-Performance Sequences of Operation for HVAC Systems," provides standardized control sequences for common HVAC system types — VAV (Variable Air Volume) air handling units, VAV terminal units, chilled water plants, and hot water heating plants. Published in 2018 with an updated edition in 2021, it represents the current best practice in HVAC control, encoding decades of building science research into implementable control logic.
