After LBC Certification: Building Performance Up Close

Todd Mowinski, Newcomb & Boyd
Darren Draper, Epsten Group, Inc.

The Kendeda Building at Georgia Tech is unique in many ways, the first project in the Southeast to achieve Living Building Challenge (LBC) certification, but also achieving certification during a global pandemic.

Because of the extensive monitoring in the building, the presentation will take a deep dive into HVAC, plumbing, and lighting systems performance, comparing and contrasting actual versus modeled performance, and how the project team dealt with the pandemic, both from a change in building operation and predicting performance had the building been in use normally.

We will also highlight the building's rule-based fault detection and diagnostic system and how it helps evaluate performance in real time against modeled expectations, common maintenance issues on campus, and potential issues identified during the commissioning process.

Learning Objectives

  • Hear about assumptions versus reality relative to heat loads and ventilation requirements;
  • Learn why a building designed inherently to be healthy was ideally suited to thrive during the pandemic;
  • Hear about how the hands-on commissioning effort was necessary to put the advanced building design into operation; and
  • Learn how to develop a process to create a rule-based fault detection system.


With over 20 years of experience in mechanical engineering design, project management, and partner-in-charge responsibilities on over 270 facilities, Todd has particular expertise in the areas of academia, medical facilities and laboratories. He has presented to international conferences and published on the topic of sustainability in HVAC design.

Darren Draper has served as a lead commissioning agent on a wide range of building projects including research laboratories, corporate headquarters, recreational facilities, government facilities, university buildings, and multi-use facilities. He is one of three instructors for the ACG Commissioning Authority Certification preparation workshop.
