The newest ASHRAE Guideline, 36-2018 High-Performance Sequences of Operation for HVAC Systems, 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
Join us for a deep dive discussion of the new Guideline, and how to apply it to your projects.
