Getting Control Strategies Right is Essential for Efficient Operations

November 16, 2017
1 p.m. – 2 p.m.
Eastern Standard Time

Three years after the nine-story, 512,000 square foot medical school science and laboratory building was built, which cost nearly half a billion dollars, it was not performing as expected. Even with its top-notch heating, ventilation, and air conditioning systems, it was not meeting expected efficiency levels. This case study presentation will show the operational analysis that revealed how the building implemented a 70 kBtu/sqft energy use intensity (EUI) reduction (translating to more than $300,000 per year in savings), as well as essential improvements for comfort conditions.

This presentation will review initial operational analysis findings, automation code review findings, specification of automation per ASHRAE 36P, automation remediation (the code for variable air volume and air-handling units), and the unplanned remediation work required to get the automation right. Results will be shown in terms of actual airflow reduction by floor and EUI reduction.

After viewing this presentation, attendees will:

  • Learn the inherent limitations of today's construction process and how it affects automation.
  • Become familiar with a new guideline and the convenience of selecting sequences of operation.
  • Learn why the remediation process for automation finds more project deficiencies.
  • Understand the different types of operational data required to operate this type of building efficiently.

Instructor Biographies

Bill Gnerre is CEO and co-founder of Interval Data Systems (IDS). Mr. Gnerre has overseen IDS' evolution from an EEMS software vendor, to an analytic services provider, to its current building automation software (BAS) service offering. He works to ensure IDS customers get the highest quality BAS automation combined with operational consulting via ongoing monitoring. Mr. Gnerre’s vision provides building owners with the lowest cost of operations in terms of energy and ongoing maintenance while delivering highest level of comfort and safety.


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.
