Sunday, January 21 Sunday, January 21, 8:00 AM - 9:00 AM Debate 1 (Intermediate) Building Automation System Graphics: Integrating Multiple Masters, Who Is the Boss? Track: Systems and Equipment Room: Adams Sponsor: 1.4 Control Theory and Application, 7.3 Operation and Maintenance Management Chair: Marcelo Acosta, P.E., Member, Armstrong Fluid Technology, Toronto, ON, Canada, Frank Shadpour, P.E., Fellow ASHRAE, SC Engineers, Inc., San Diego, CA and Larry Scholl Jr., Member, Automated Logic, Kennesaw, GA Building automation graphics are the users' primary interface with the system. As such, the interface should support the users effectively and efficiently in accomplishing their work. When an owner expands or adds automation capability, the Graphical User Interface should painlessly extend too. BACnet was established to promote free enterprise for open, non-proprietary building automation, but does seamless integration exist for user interfaces? One speaker argues the graphic interface is the “hook” controls companies use to control the owners. The other speaker argues properly specified user interfaces and data sharing allow today for vendor independence, and shows how it’s done. 8:00 AM - 9:00 AM Seminar 1 (Intermediate) Campus Operators Reflect on Using Guideline 22 and Standard 90.1 for Chiller Plant Monitoring Track: Standards, Guidelines and Codes Room: State Sponsor: 8.2 Centrifugal Machines, 9.1 Large Building Air-Conditioning Systems Chair: Dwayne Johnson, Trane, La Crosse, WI Ever wonder how ASHRAE guidelines and standards make a difference? In this session you'll hear testimony from two facility managers who use ASHRAE guidance to get the right data to make informed decisions about their chiller plant operation. 1. University Campus Chiller Plants: ASHRAE Guideline 22 and Standard 184P in Operation John Vucci, Member, University of Maryland, College Park, MD This seminar gives real examples of the benefits of measuring chiller plant performance following ASHRAE Guideline 22 and Standard 90.1, a case study presented of performance for multiple plants, including variable primary, primary secondary and a hybrid electric and steam chiller plant at University of Maryland. 2. Healthcare Chiller Plants: ASHRAE 90.1 Chiller Plant Monitoring and Beyond Tim Peglow, P.E., Associate Member, MD Anderson, Houston, TX MD Anderson has been using data to decide how to run their chiller plants for years. ASHRAE 90.1 chiller plant monitoring requirements set down the basics of the kinds of information necessary for informed decisions. A recent project went further into using advanced analytics to operate a complex, multiple chiller and-multiple building loop to improve and better monitor chiller plant performance. This session describes lessons learned and the outcome of their overall energy efficiency improvements. 2 Sunday, January 21 8:00 AM - 9:00 AM Seminar 2 (Advanced) Stack Effect: Friend or Foe in Tall Buildings Track: Tall Buildings Room: Empire Sponsor: 9.12 Tall Buildings Chair: Dennis Wessel, Ph.D., P.E., Fellow Life Member, Retired, Cleveland, OH Stack effect in tall buildings is caused by the combination of the building height and buoyancy of air caused by temperature difference between inside and outside. Stack effect causes convective air flow in tall buildings and when combined with wind forces, elevator piston effects, and internal airflow path resistance of building elements, the associated pressure differences can cause detrimental effects or can potentially assist natural ventilation possibilities. This seminar discusses issues, both positive and negative, caused by stack effect in tall, super tall and mega tall buildings for select cities around the world. 1. Methods to Mitigate Stack Effect in Supertall and Megatall Buildings Mehdi Jalayerian, P.E., Member, ESD, Chicago, IL Stack effect is movement of air in buildings due to air buoyancy caused by indoor/outdoor temperature. Uncontrolled airflow and pressure related to stack effect always exists but is exacerbated by outdoor ambient conditions and building height/configuration. This presentation provides a parametric review of stack effect conditions for realistic configuration of megatall towers and establishes design considerations related to geographic design conditions, envelope construction, lobby configuration, space pressurization, sky-lobbies, observation level access and stairwells/shafts. The financial and disruptive risks of stack effect can be effectively mitigated if analyzed holistically and addressed early in the design of supertall and megatall towers. 2. Measurements of Stack Effect in Existing Tall and Supertall Buildings Duncan Phillips, Ph.D., P.E., Associate Member, RWDI, Guelph, ON, Canada Stack effect is a phenomenon that exists in all buildings and structures that are at a different temperature, thus air density, from outdoors. While the effects of stack effect can be estimated, measurements from tall buildings are rare. This seminar presents measurements of stack effect in tall and supertall buildings, for both hot and cold climates. The measurements include vertical profiles of pressure from elevator shafts to ambient through multiple barriers/partitions. These measurements show that some of the assumptions maintained during design are incorrect and that solving the stack effect phenomenon is complex. 8:00 AM - 9:00 AM Forum 1 Ventilation Effectiveness: What Is It? Track: Fundamentals and Applications Room: Monroe Sponsor: MTG.ACR, 9.10 Laboratory Systems, 9.11 Clean Spaces, 9.6 Healthcare Facilities Chair: Kishor Khankari, Ph.D., Fellow ASHRAE, AnSight LLC, Ann Arbor, MI Ventilation effectiveness is often perceived as an efficiency measure of air distribution. However, the definition and application of ventilation effectiveness can vary from application to application. Is there a universal definition of ventilation effectiveness? Can it be measured? Can it be monitored? Can air change rate alone affect the ventilation effectiveness? What other parameters affect the ventilation effectiveness? How can it be implemented as a design parameter? This session brainstorms these questions and will attempt to identify current state of the art of ventilation effectiveness and future needs in HVAC industry. 8:00 AM - 9:00 AM Workshop 1 (Intermediate) District Chilled Water and Building Systems Heat Exchange Equipment and Impact on Operations Track: Heat Exchange Equipment Room: Honore Sponsor: 7.3 Operation and Maintenance Management Chair: John Constantinide, Member, Alpha MRC Architects Engineers, Merritt Island, FL New refrigerant types, design of heat exchange equipment and district energy systems offer opportunities for savings in operations and maintenance of central plants.
