Conference Event Information

Orlando Meeting, February 2020
TC 9.6 is sponsoring/co-sponsoring the following technical sessions:


Seminar 4: Moving BAS for Hospitals into the Future

Sunday, February 2, 8:00 AM–9:00 AM
Location: Hilton Orlando, LL, Orange F
Summary: Hospital facilities are evolving to better serve the needs of staff and patients. Hospital BAS are evolving to support the new, higher level of function. This includes integrating new medical systems, upgrading to operate in today's computer networks, delivering data that supports accreditation programs and maintaining operation through development.


Seminar 26: ASHRAE/REHVA Guidebook Towards Zero Energy Hospital Buildings

Monday, February 3, 8:00 AM–9:30 AM
Location: Hilton Orlando, LL, Orange E
Summary: Learn about the new ASHRAE/REHVA guidebook for Zero Energy Healthcare Buildings. The guide presents a justification for pursuit of zero (and nearly zero) energy healthcare buildings, defines overall strategies and presents specific methods that may contribute to achieving a zero or nearly-zero energy facility.


Seminar 57: The History of the Use of Air Changes per Hour in HVAC Codes, Standards and Guidelines

Tuesday, February 4, 3:15 PM–4:45 PM
Location:Hilton Orlando, LL, Orlando VI
Summary: Many codes, standards and guidelines specify ventilation requirements in terms of air changes per hour, but where did they originate and when? How have prescribed ventilation requirements changed through history as research and industry preferences have changed? This thought-provoking journey from Florence Nightingale through clean manufacturing, from sick buildings through healthy spaces, and from air movement to ventilation effectiveness will challenge your preconceived notions and explore future opportunities to improve our indoor environments.



 Other programs that may be of interest:


Seminar 2: Improve IAQ by Avoiding Architect, Engineer and Contractor's Common Mistakes

Sunday, February 2, 8:00 AM–9:00 AM
Location: Hilton Orlando, LL, Orlando V
Summary: IAQ deteriorates from lack of moisture control due to common mistakes by architects, engineers and contractors. This seminar points out at least five often repeated mistakes that designers and constructor make that increase moisture levels and resultant microbial contamination resulting in poor IA.

Seminar 21: Putting People First: The Healing Power of Indoor Air

Sunday, February 2, 1:30 PM–3:00 PM
Location: Hilton Orlando, Orlando VI
Summary: Increasing numbers of people are struggling against virulent infections, allergic and inflammatory diseases. Are we missing an important environmental factor that simultaneously makes us more vulnerable while it strengthens pathogenic micro-organisms? This session presents data showing how IAQ is related to these alarming health trends, and how design and management of HVAC systems can improve occupant health. Understanding the influence of IAQ on humans is not just theoretically interesting; it has become an urgent topic for all of us. For those interested in the business case for managing IAQ to support occupant health, financial models will be presented.

Seminar 32: Surviving Natural Disasters

Monday, February 3
9:45 AM–10:45 AM
Location: Hilton Orlando, LL, Orange E
Summary: This seminar will go over ways to help mechanical systems in buildings survive disasters such as shaking from earthquakes, severe wind, and TC 2.7's newest addition, equipment that is protectable in flood zone areas of the world. There are ways that this can be done. some will include the use of the ASHRAE Manual, "Practical Guide to Seismic Restraint", which includes chapters on the restraint of equipment for wind loads.

Seminar 35: HEPA Filters and Healthcare Cleanroom Design for Compounding and Operating Room Spaces

Monday, February 3
11:00 AM–12:00 PM
Location: Hilton Orlando, LL, Orange G
Summary: This seminar covers HEPA filter particle capture mechanism and HEPA filter type for different applications; cleanroom HVAC design for USP 797 and USP 800 compounding spaces; and cleanroom HVAC design for operating rooms.

Paper Session 4: Indoor Environmental Quality with an Emphasis on Thermal Comfort

Sunday, February 2, 11:00 AM–12:30 PM
Location: Hilton Orlando, LL, Orange A
Summary:This session considers indoor environmental quality and thermal comfort, while considering measurements, heat stress index, ceiling fans and solar screens. This first study examines IEQ parameters, including pressure, illuminance level, acoustics, carbon dioxide levels, temperature and humidity, with appropriate monitors allocated during the same lecture hour in four lecture halls from October 2018 to March 2019. Results were compared to ventilation guideline for lecture halls by ASHRAE. The second paper introduces an algebraic-type heat stress index called ETV and how it can be used to estimate the duration limit of exposure under different indoor environmental and personal conditions. In the third paper, the results suggest that despite lower air speeds, fans blowing upwards can provide more spatially uniform thermal comfort under elevated air speeds, requiring less consideration of occupant and furniture placement relative to the fan. The fourth paper asks, how fenestrations like solar screens can be designed to achieve thermally dynamic indoors for occupant pleasure.

Paper Session 10: CFD Modeling for Ventilation

Monday, February 3, 8:00 AM–9:30 AM
Location: Hilton Orlando, LL, Orange A
Summary: This session focuses on applications of computational fluid dynamics (CFD) to improve infection control in offices, sensor placement for demand controlled ventilation, effects of door opening and designing ventilation for dairy barns. The first paper analyzes the simulation of pollutant transmission characteristics in an office room with infectious person, including the ability of the ventilation system to reduce the risk of infection inside such rooms. In the second paper, CO2-based demand controlled ventilation has the potential to achieve energy saving while maintaining acceptable indoor air quality. However, sensor placement is important. The third paper studies CFD of door opening, with the main aim of studying the change in airflow patterns with respect to the wall location. The fourth paper presents actual modeling to design a real ventilation system for a 42,000ft2 dairy farm in cold Canadian weather.




Attend a Committee Meeting

ALL ASHRAE committee meetings, including this TC’s meetings at the Winter and Annual Society conferences, are open to the public at no cost nor is conference registration required. Interested visitors, local chapter members, and potential new TC members are always welcome. However to attend technical program sessions sponsored by the TC will require registration and payment of any applicable fee.

Participation in an ASHRAE TC provides the opportunity to grow professionally and to contribute to the advancement of HVAC&R within an international organization recognized for shaping the future of the built environment through research, standards writing, publishing, and education.
