ASHRAE Guideline 36-2018 
High-Performance Sequences of Operation for HVAC Systems

Full Description

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
