Automated Fault Detection and Diagnostic and How to Apply It at Your Facilities

November 18, 2015
1 p.m. – 2 p.m.
Eastern Standard Time


As large commercial buildings strive for ever increasing levels of energy efficiency and operational performance, design engineers are specifying complex and sophisticated heating, ventilation, and air conditioning (HVAC) and building automation systems. Over time, this complexity often broadens the gap between design intent and the in-situ performance of commercial buildings: equipment degrades, controls change, and facilities operation staff may be unable to keep up with maintenance requirements. Retro-commissioning is a process undertaken to resolve these operational problems, improve comfort, and optimize energy use for the current use of the building.

During this webinar, the presenters will discuss how automatic fault detection and diagnostic (AFDD) software tools can gather data to identify areas in a building that need to be upgraded beyond the retro-commissioning process. The presenters will provide details of how retro-commissioning using AFDD was applied to the National Renewable Energy Laboratory Science and Technology Facility and the results of the project.

Attendees will:

  • Gain an understanding of what AFDD is.
  • Understand the benefits of using AFDD as part of retro-commissioning.
  • Understand the results NREL obtained at the S&TF by hiring Group14, a retro-commissioning expert utilizing AFDD.
  • Gain an understanding of how to evaluate their own facilities for the potential use of AFDD.
