Sunday, February 2, 8:00 AM–9:00 AM

Seminar 1 (Intermediate): Building-Integrated Photovoltaic Systems: Enabling Energy-Resilient High-Performance Buildings

Program Track: Systems and Equipment
Location: Hilton Orlando, Orange Ballroom E
Chair: Eric Yang, P.E., BEAP, HBDP
Distributed energy resources have a key role to play in the transition towards decarbonization and energy resilience of buildings. Recent developments in building-integrated photovoltaic (BIPV) systems and standards are making this technology a key component to achieve such transformation. In addition to producing electricity, BIPV also provides various functions of the building envelope while maintaining an aesthetically pleasing architecture. The objective of this seminar is to discuss the technical challenges and available solutions regarding BIPV systems design, implementation and operation. In this seminar, the attendees will gain an understanding of BIPV fundamentals, design and implementation challenges and technical solutions.

Seminar 13 (Intermediate): Current Practices of Grid Interactive Building Applications
Program Track: Cutting Edge Approaches
Location: Hilton Orlando, Orlando V
Chair: Christie Kjellman
Buildings can now be used as suppliers of energy rather than the traditional model of solely consumers of energy. Price signals, model predictive control and responsive building loads are tools which can be utilized to allow and promote grid interactive buildings. This session presents applications of where, how and why smart residential, commercial and industrial buildings and interactive grids are being implemented around the country.

Seminar 37 (Intermediate): Show Me the Money! Cost-Based Control of Supply Air Temperature
Program Track: Big Data and Smart Controls
Location: Hilton Orlando, Orlando VI
Chair: Taraneh Shoorideh, P.E.
The complexity of supply air temperature reset strategies varies greatly, from a simple reset based on outside air temperature to highly complex strategies based on model predictive control. ASHRAE Guideline 36 outlines the current industry best practice approach. But what if we could significantly improve performance over Guideline 36 without overwhelming complexity? The speakers discuss results from simulation analysis and field evaluation of a novel cost-based control strategy for supply air temperature reset.

2. Simulation Analysis of Cost-Based Supply Air Temperature Reset in Multiple Buildings

Presenting Author: Hwakong Cheng, P.E., Taylor Engineering LLC, Alameda, CA, USA

Tuesday, February 4, 9:45 AM–10:45 AM
Seminar 45 (Intermediate): BACnet Secure Connect: What You Need to Know!
Program Track: Big Data and Smart Controls
Location: Hilton Orlando, LL, Orange E
Chair: Carol Lomonaco
BACnet Secure Connect (a.k.a. BACnet/SC) is a new protocol addition to the current BACnet standard ANSI/ASHRAE 135 that eliminates many of the security concerns building automation manufacturers, facility managers and IT professionals have with BACnet IP today. A virtual "Hub and Spoke" topology is used to form a BACnet/SC network. BACnet/SC is based on HTTPS over TLS v1.3 secure communications similar to online banking connections. With the use of TLS, security keys come into effect in the form of X509 certificates. This seminar explains what is BACnet/SC, its many benefits and BACnet/SC can be deployed within existing buildings, etc.

1. Introduction to BACnet/SC
Presenting Author: Michael Osborne, P.Eng., Reliable Controls Corporation, Victoria, BC, Canada

2. BACnet/SC

Presenting Author: Bernhard Isler, Siemens Switzerland Ltd Building Technologies Division, Zug, Switzerland


Wednesday, February 5, 8:00 AM–9:30 AM
Seminar 60 (Intermediate): Control for Grid Interactive Buildings: A Look Toward the Future

Program Track: Big Data and Smart Controls
Location: Hilton Orlando, LL, Orange E
Chair: Michael Brambley, Ph.D.
Trends in the electric power grid are driving changes in the relationship between the grid and buildings, which consume nearly 75% of U.S. electric power. Increasing amounts of renewable wind and solar photovoltaic generation because of their variability present new challenges in balancing supply and demand on the grid. As the largest user of electricity, buildings will likely be called upon in the future to help manage the grid through control of demand in exchange for incentives. This seminar describes control methods beyond current demand response that will enable both commercial and residential buildings to interact effectively with the grid.
