Control Theory and Application
ASHRAE Technical Committee 1.4

Meeting Information

TC 1.4 is sponsoring several technical programs at the Atlanta Winter 2019 Meeting.

Sunday, January 13
9:45 AM–10:45 AM
Seminar 9: The Doctor is In! Diagnosing Common System Issues and Misapplications in Building Automation Systems                                                                          
Location: GWCC, 4th Floor, Building A, A404
Program Level: Intermediate
Session Type: Seminar
Program Track: Common System Issues and Misapplications
Location: GWCC, Building A, A404

Summary:
A building automation system is the central nervous system of the HVAC system, but most engineers tasked to run a facility through these systems see them only as black boxes. Designed and configured correctly, they become a force multiplier for operations personnel. Configured sub-optimally, they become a liability and create additional problems to distract facility
operators from their primary responsibilities. But how can anyone determine the proper configuration of a system built with proprietary software and programming language? This seminar presents proven methods for non-controls technicians to identify and address common issues present in existing building automation systems.

Seminar 37: Space Pressurization for Infection Control and Hospital Accreditation
Monday, January 14
11:00 AM–12:00 PM

Location: GWCC, 3rd Floor, Building A, A305


Program Level: Intermediate
Session Type: Seminar
Program Track: Construction, Operation, and Maintenance of High Performance Systems
Location: GWCC, Building A, A305

Summary:
To maintain accreditation, the operations staff in a hospital has to maintain and demonstrate performance of the HVAC systems that pressurize critical spaces. Success starts with mechanical design principles and continues through construction and commissioning. Finally, it persists in a formal, documented performance monitoring program. This session explains physical aspects of pressurization, analyzes design approaches and design decisions. Finally, it presents the ideas and execution of a monitoring and maintenance program that supports infection control and accreditation.

Seminar 44: How was that Supposed to Work Again? The Importance of Documented and Understandable Sequences of Operation throughout the Life Cycle of a High Performance Building
Tuesday, January 15
8:00 AM–9:30 AM

Location: GWCC, 4th Floor, Building A, A404

Program Level: Intermediate
Session Type: Seminar
Program Track: Construction, Operation, and Maintenance of High Performance Systems
Location: GWCC, Building A, A404

Summary:
Facilities personnel come and go. Training to understand the HVAC system in their building is always a challenge. A properly constructed narrative and graphical style Sequences of Operation is potentially the best training tool available as subsequent generations of building personnel are trained. This seminar discusses how a narrative sequence can serve the purposes of both immediate construction and long term operations.

Seminar 47: Securing BACnet Networks: Present and Future
Tuesday, January 15
8:00 AM–9:30 AM

Location: GWCC, 3rd Floor, Building A, A305

Program Level: Intermediate
Session Type: Seminar
Program Track: HVAC&R Fundamentals and Applications
Location: GWCC, Building A, A305

Summary:
Securing BACnet networks for confidentiality, integrity and availability (aka CIA Triad) becomes a requirement that should not be neglected. Methods to secure BACnet networks are available today and are outlined in this seminar. BACnet Secure Connect (BACnet/SC) is a new networking option to be added to BACnet which supports IT security for BACnet communications using standard IT technologies used in other critical applications such as online banking. Audit logging and reporting is a complement to securing the communications. Recently added to the standard, it specifies reporting and logging of auditable operations performed by client and server devices on a system.

Seminar TC: Presentation 1: Want to Control the World?
Tuesday, January 15
1:00 PM–1:20 PM

Location:TBD

Days: Tuesday, 15 January
Session Type: Seminar

Want to Control the World?
Presenting Author: Michelle Shadpour, SC Engineers, Inc., San Diego, CA, USA

Many millennial engineers view controls as a mysterious black box, however advanced building integrated controls are a key feature in moving toward a net zero energy future. How will we move toward this future if our engineers don't know how to design it? TC 1.4 has implemented a social media approach to educate and familiarize all engineers with controls theory and application using one of the most popular platforms among young engineers. Through the use of fielded questions and answers by experts within the HVAC&R industry, controlling the world will prove to not be as intimidating as young engineers think.

Learning Objectives:
• Recognize the expanse of controls theory and application in the HVAC industry
• Describe how the future of the controls industry will impact engineers
 
 
Seminar 68: Integration of Renewable Systems and Natural Ventilation: Control Challenges
Wednesday, January 16
9:45 AM–10:45 AM

Location: GWCC, 3rd Floor, Building B, B309

Session Type: Seminar
Program Track: Renewables and Natural Systems
Program Level: Advanced
Location: GWCC, Building B, B309

Summary:
Smart engineers are designing even smarter buildings but what are the challenges to getting there? The application of smart systems has resulted in a duplication of effort and, at times, results in conflicting controls parameters. This seminar identifies proper application, monitoring and integration of sustainable systems into the building automated controls and examines resulting issues that may arise. This seminar tackle these issues because a building can only perform as great as the control system allows it!

 Seminar 71: How to Ensure that Your Building Control Improvements Actually Last
Wednesday, January 16
11:00 AM–12:30 PM

Location: GWCC, 3rd Floor, Building B, B315

Program Level: Intermediate
Session Type: Seminar
Program Track: Construction, Operation, and Maintenance of High Performance Systems
Location: GWCC, Building B, B315

Summary:
Do the improvements and retrofits that we make to building controls actually persist over time? This seminar explores that question for a number of different scenarios including retrocommissioning, new building commissioning and general retrofit of building automation. Results from primary research on the subject are presented as well as first-hand accounts from controls and commissioning contractors in the field. The session also demonstrates methods for improving persistence, including longer term activities like monitoring.
