 TC 7.5 is sponsoring/cosponsoring these technical sessions at the ASHRAE 2019 Annual Conference:

Sunday, June 23, 11:00 AM - 12:30 PM
Seminar 9 (Intermediate)
Automated Fault Detection and Diagnostics Software for Cx, RCx and MBCx

Program Track: Commissioning New & Existing Buildings
Location: 2101
Sponsor: 7.5 Smart Building Systems
Chair: Xiaohui Zhou, Ph.D., Member, Slipstream, Madison, WI
There have been major developments in the past few years in commercially available automated fault detection and diagnostics (AFDD) software, used for detecting sub-optimal system performance in the commercial buildings. They have been used successfully in commissioning (Cx), retro-commissioning (RCx), and monitoring-based commissioning (MBCx). These tools can pinpoint then prioritize efficiency and cost saving opportunities, track savings, easy to integrate with existing building automation systems and some provide it as a Software-as-a Service (SaaS) option. This seminar will focus on discussing the applications of AFDD software as a useful tool for Cx, RCx, and MBCx.

Monday, June 24, 9:45 AM–10:45 AM
Seminar 30 (Intermediate)

Evaluating Automated Fault Detection and Diagnostics Tools for Commissioning New and Existing Buildings
Program Track: Commissioning New & Existing Buildings
Location: KCCC, 2104B
Chair: Jin Wen, Ph.D.
AFDD tools are significant components during a commissioning process, especially for RCx and MBCx. Many AFDD tools exist in the market and new AFDD strategies are being developed from research activities. However, there is a lack of data, testbed, and testing method that can be used to evaluate AFDD tools. How to estimate energy and indoor environment impacts from an AFDD process also lacks consensus. In this seminar, teams from three national laboratories will discuss their ongoing projects funded by the U.S. Department of Energy Building Technology Office, which focus on generating data and developing methods for evaluating AFDD tools.

1. Evaluating the Performance Building Fault Detection and Diagnostics Algorithms and Tools

Tuesday, June 25, 8:00 AM–9:30 AM

Seminar 39 (Advanced)
Model-Predictive Control for HVAC System Optimization
Program Track: Optimization in HVAC&R
Location: KCCC, 2103C
Chair: Eric Yang, P.E.
Model-predictive control (MPC) based optimization approaches present a promising solution for increasing the operational efficiency of HVAC systems. This seminar discusses MPC optimization technologies, including a novel MPC approach, a field evaluation study, and a framework for performance benchmarking.
Using a dynamic data-driven model or physical-based model and disturbance forecast to predict HVAC system performance, this provides a given objective and taking into consideration future events. It combines the models with the real-time data from the building automation system (BAS) to determine the optimal control setpoints and feedback to the BAS to minimize energy consumption or costs.

1. Adaptive Model-Based Predictive Control for HVAC
Presenting Author: Draguna Vrabie, Ph.D., Pacific Northwest National Laboratory, Richland, WA, USA

2. Field Evaluation of Model-Predictive Optimized Control System in Commercial Buildings
Presenting Author: Guanjing Lin, Ph.D., Lawrence Berkeley National Laboratory, Berkeley, CA, USA

3. A Framework for Comparing Model Predictive Control Solutions: Needs and Approach
Presenting Author: David Blum, Lawrence Berkeley National Laboratory, Berkeley, CA, USA

Tuesday, June 25, 11:00 AM–12:30 PM

Seminar 54 (Advanced)
Optimal Chilled Water Plant Design and Operation: What a "Smart Valve" Can Do for You
Program Track: Systems & Equipment in the Built Environment

Location: KCCC, 2104B
Chair: Scott Hackel
Pressure independent control valves (PICV) have been used in optimizing chilled water plant design and operations. New "smart valves" added more sensing and metering capability as well as intelligent control and cloud connectivity on top of the PICVs, making them more "smart." However, many engineers still struggle in understanding when and how to use them properly in design and operation. This seminar will objectively discuss the applications for PICV and smart valves.

1.What Is a Smart Valve?
Presenting Author: Jon Hildebrand, BELIMO Aircontrols (USA), Inc., Danbury, CT, USA

2.Smart Valves for Full System Optimization
Presenting Author: Jeff Creighton, FlowEnergy, LLC, Woodlinville, WA, USA

3. Practical Applications for Pressure Independent and Smart Control Valves
Presenting Author: Steve Taylor, P.E., Taylor Engineering, Alameda, CA, USA

Wednesday, June 26
8:00 AM–9:30 AM

Seminar 59 (Intermediate)
Energy Systems Integration and Smart Grid-Ready Buildings: All You Need to Know to Be a Good Grid Citizen

Program Track: Systems & Equipment in the Built Environment
Location: KCCC, 2105
Chair: Janice Means, P.E.
As the built environment is moving towards decarbonisation, the electric grid will require new design and operation considerations to integrate increasingly high levels of renewable energy. The grid also incorporates intelligent buildings capable of managing their own loads and storage capacity to 1) reduce their energy use and peak power demand, and 2) support grid flexibility and grid services that will have increasing value to grid operators. The objective of this seminar is discussing the technical challenges and available solutions regarding energy systems integration, distribution intelligence, the role of buildings, and steps required to operate in a smart-grid environment.

1. Smart Grid-Ready Buildings: Enabling Tools and Solutions
Presenting Author: Glenn Remington, Consumers Energy, Jackson, MI, USA

2. Smart Grid Distribution Intelligence: Towards a Resilient, “Self-Healing” Grid
Presenting Author: Andy Haun, Schneider Electric, Andover, MA, USA

3. Integration of Renewable Energy Systems: Opportunities and Challenges
Presenting Author: Aaron Bloom, Energy Systems Integration Group, St. Paul, MN, USA
