TC 7.5 is sponsoring/cosponsoring these technical sessions at the ASHRAE 2023 Winter Conference:


Sunday, February 5 9:45 AM – 10:45 AM EST

Seminar 11: Optimizing Thermal Energy Storage Integrated with HVAC

Room: Georgia World Congress Center, A408

Chair: Kyle Gluesenkamp, Ph.D.

Integrating thermal energy storage (TES) with HVAC systems can enhance the performance and grid interactivity of buildings. This seminar covers the use of optimization techniques to identify favorable system design and operating controls for TES-integrated HVAC. The seminar addresses residential heat pumping and air conditioning, as well as chilling for a large production facility. Adding TES to HVAC introduces additional design parameters and operating variables. The research in this seminar demonstrates how optimization techniques can be used to identify favorable designs for advanced HVAC with TES.

Seminar 40: Standardized Building Datasets for Benchmarking Control Algorithms, Energy Efficiency, Modeling and Decarbonization

Room: Georgia World Congress Center, A405

Chair: Farhad Omar, Ph.D.

The electrical grid is undergoing significant changes due to a two-way flow of energy and information. Buildings can be essential assets in managing grid operation and supporting decarbonization efforts while maintaining thermal comfort and reducing cost. Access to high-quality standardized benchmarking datasets is a functional requirement for grid-interactive buildings. Standardized benchmarking datasets for behind-the-meter customer loads and distributed energy resources can support the development of analytical methods for assessing demand flexibility, control and optimization of building operation, measurement, verification, modeling, simulation, data management tools and metrics for evaluating technologies for the reliability and consistency of services delivered to the grid.

Seminar 43: How Common are Residential HVAC Installation Faults, and How Can We Detect Them? Results from the DOE Building America Program

Room: Georgia World Congress Center, A405

Chair: David Yuill, PE

The Building America program of the US Department of Energy is supporting projects focused on residential air-conditioner and heat pump faults. One project examines how common it is for installation faults to occur, based on a large national study of houses in the US; another project proposes a way to use smart thermostats to diagnose faults; and a third project examines the effectiveness of methods for detecting and diagnosing faults. These presentations will give the latest results of current cutting-edge research on residential system faults, and a rare glimpse into the future of high-performance home comfort systems.

1. How Common Are Installation Faults in Residential Air-Conditioners and Heat Pumps?
Presenting Author: David Yuill, PE, University of Nebraska, Lincoln, NE, USA

2. Home Air-Conditioner Fault Detection and Classification Using Low-Cost Smart Thermostats and Smart Meters

Presenting Author: Zheng O'Neill, Ph.D., P.E., Texas A&M University, College Station, TX, USA



Tuesday, February 7 11:00 AM – 12:30 PM EST

Seminar 50: LIVESTREAM: Managing the Complexities of Cybersecurity

Room: Georgia World Congress Center, A410

Chair: Carol Lomonaco

The convergence of BAS and IT is with us today, and with it comes an imperative for BAS professionals to understand and plan for the impact of cybersecurity on BAS networks and systems. This seminar informs attendees of the path to interoperable and secure BACnet systems. This path requires an understanding of the complexity of cybersecurity, the need for a standardized management framework, finding the best way to work with IT, and the galvanization of the industry to collaborate around best practices so we can collectively deliver secure and interoperable building systems.

1. Why Is BAS Cybersecurity so Complex?
Presenting Author: James Lee, Cimetrics, Inc., Boston, MA, USA

2. How Standards in BAS Networks Can Help Solve Cybersecurity Complexities
Presenting Author: Ken Gilbert, Automated Logic Corporation, Kennesaw, GA, USA

3. Accelerating Progress through Industry Collaboration
Presenting Author: Andrew McMillan, BACnet International, Atlanta, GA, USA



Wednesday, February 8 11:00 AM – 12:30 PM EST

Seminar 67: SPIRE, WELL, Building EQ: New Certifications for Smart, Healthy and Efficient Buildings

Room: Georgia World Congress Center, A403

Chair: David Yuill, PE

There is a truism that what you measure is what you get. Building ratings and labeling systems are a way to measure high performance in buildings, during design and operation. Three new and widely-used certification systems will be described in this seminar. WELL certification quantifies healthy and safe indoor environments. SPIRE is the first comprehensive Smart Building assessment and rating program. Building EQ is ASHRAE’s labeling program for energy usage. Speakers give presentations going from overview to details and examples, that benefit building designers, operators, occupants and professionals.
