New High Performance ASHRAE Guideline for SOO, Alarms and Fault Detection

Bill Gnerre, Interval Data Systems
Gregory Cmar, Interval Data Systems

ASHRAE has released a new High-Performance Building guideline G36 to operate buildings more efficiently. It has 3 areas of interest to the science building community. More efficient Sequences of Operations than previously defined by ASHRAE, a structured approach to alarming (yeah), and fault detection routines to verify operational performance. In this session we'll review:

  • Theory of ASHRAE G36 High Performance Building Guideline
  • Trim and Respond Basics
  • Equipment requests (SP, SAT, Ventilation)
  • Structured Approach to Alarms with Alarm Levels and Hierarchical Alarm Suppression
  • Fault Detection Rules
  • How to apply Guideline 36 for lab buildings
  • Tested Sequences of Operations for lab buildings
  • Static pressure reset
  • Supply Air Temperature reset
  • Night Set-Back for VAV and AHU's

Learning Objectives

  • Understand G36 High Performance Building SOO fundamentals such as Trim and Respond for static pressure reset, supply air temperature reset, and control of ventilation to ASHRAE 62.1
  • Learn how to use Guideline 36 in the mechanical design of lab building's automation so that the building runs as designed.
  • Learn G36's structured approach to alarms by learning hierarchical alarm suppression and alarm level prioritization to greatly reduce the number of unnecessary BAS alarms.
  • Learn how to verify conformance with ASHRAE G 36 via actual operational data

Biographies:

Bill has kept IDS focused on one vision to operate buildings in conformance with comfort and health/safety standards, at the lowest operating cost. IDS offers a turnkey BAS automation operational improvement service. After operational improvement targets are achieved owners can continue to monitor building performance through the EnergyWitness analytics platform. IDS was recently selected by DOE's Smart Energy Analytics Campaign as 2017's Outstanding Monitor Based Commissioning provider.

Greg Cmar is CTO and co-founder of IDS. Mr. Cmar architected and developed the EnergyWitness EEMS database and software platform from data collection (BAS, meters, utility) to today's data modeling, fault detection, and diagnostic analytics. He is IDS' operational expert who interprets BAS data and specifies SOO per ASHRAE 36P and commissioning automation code. In his remediation role, Mr. Cmar leads control technicians through the process to achieve the automation quality IDS requires.
