Guideline 36-2021 -- High-Performance Sequences of Operation for HVAC Systems

ASHRAE Guideline 36 provides uniform sequences of operation for HVAC systems that are intended to maximize the systems' energy efficiency and performance, provide control stability, and allow for real-time fault detection and diagnostics.

Standardized advanced control sequences provide benefits including reduced engineering time, reduced programming and commissioning time, reduced energy consumption, improved indoor air quality, and a common set of terms to facilitate communication between specifiers, contractors, and operators.

The 2021 edition of the guideline includes 24 addenda that address sequences of control for the following:

* Heating hot-water plants

* Chilled water plants

* Fan-coils

* Automatic and dynamic calculation of VAV box minimum airflow set points

* Miscellaneous improvements and bug fixes
