Seminar 4: What Happened to our Hospitals after the COVID-19 Fiasco? HVAC Design, Control and Operation

Sunday, June 26 8:00 AM – 9:00 AM EDT

Location / Room: Sheraton Centre Toronto, Grand East (LC)

Summary: Most of our hospitals survived the COVID-19 fiasco; and, quite frankly, we don't know how. Every hospital scrambled to remain operational, including providing makeshift negative pressure rooms to safeguard its occupants to the extent possible. Now what? We need to plan for the battles of the future rather than focusing on the wars of the past. This seminar focuses on the lessons learned and presents the latest technology for the proper design, control, and operation of hospitals. New standards regarding air changes per hour, filtration and building automation are among the topics of discussion.

 

Seminar 21: Designing for Air Source Heat Pumps in Cold Climates

Monday, June 27 9:45 AM – 10:45 AM EDT

Location / Room: Sheraton Centre Toronto, Dominion South (2)

Summary: This presentation deals with lessons learned from a recent Ontario healthcare project, which introduced hydronic Air Source Heat Pumps (ASHPs) to help transform an existing office building into a minor procedures centre. When considering overall seasonal efficiency, ASHPs present a much stronger case than traditional electric systems. However, they cannot perform reliably on a design day. Pulling from operation data from of a full calendar year, we will explore the possibilities and challenges associated with this implementation, as well as other uncommon new strategies that support energy efficiency.

Seminar 11: Applying UV as Best Practices and Pandemic Preparedness to Address Air and Surfaces Disinfection within Buildings

Sunday, June 26 1:30 PM – 3:00 PM EDT

Location / Room: Sheraton Centre Toronto, Dominion North (2)

Summary: UV disinfection played an important role as part of a layered strategy for addressing airborne and surface contamination during the COVID-19 pandemic. Applying UV disinfection to air and surfaces within the HVAC system, duct work, and occupied spaces should not only be reserved for pandemic preparedness but also a best practices strategy for improved sanitized spaces and better IAQ for building occupants. This seminar discusses various applications using UV disinfection, such as upper air, surface, airstream, HVAC as well as the different types of UV wavelengths being applied to achieve a healthier building.

 

Conference Paper Session 2: COVID and Healthcare

Sunday, June 26 9:45 AM – 10:45 AM EDT

Location / Room: Sheraton Centre Toronto, Osgoode (LC)

Summary: The COVID pandemic has focused a sharp light on HVAC systems and their roles in both spreading and mitigating the spread of airborne pathogens. The papers in this session discuss utilization of HVAC systems for mitigation.

 

Conference Paper Session 10: Presentation 1: De-Carbonization of Hospitals, Maintaining Operational Resiliency with a Grid in Transition (TO-22-C032)

Monday, June 27 11:00 AM – 12:00 PM EDT

Location / Room: Sheraton Centre Toronto, Osgoode (LC)

Summary: Local, State and Federal policy are being enacted to decarbonize the built environment and the means by which buildings are fueled/powered. Many policies are pushing for electrification of heating and transportation systems using low- or no-carbon fuels. Electrification however will result in unprecedented changes in behavior including a significant increase in connected load, as well as peak load shifts both daily, and seasonally. The electric grid will need to evolve and adapt to accept a generation mix that is majority renewable; and require significant upgrades transmission and distribution (T&D) infrastructure and capacity. This paper explores the risks to Hospitals from electrification and a transitioning grid. Healthcare institutions often achieve their paramount essential reliability and uptime by utilizing grid electricity supplemented by natural gas and fuel oil. In an electrification scenario, the grid potentially represents a single point of catastrophic failure. There are technological obstacles that must be overcome before the electric system can be fully de-carbonized, and carbon free fossil fuel alternatives can become a viable fuel source available at scale. Determining the appropriate time horizon when the grid has achieved adequate resiliency to accept the full electrification of mission-critical loads, such as Hospitals, will be difficult to project due to the dynamic changes proposed on the system, including load; transmission and distribution; and generation components. Policy makers should proceed cautiously to ensure that mission-critical infrastructure is not put at risk. Further, there is a need for the development of new grid reliability/resiliency metrics and benchmarks that must be reached to ensure that mission-critical infrastructure and services can be fully migrated to the grid safely. During this transition period Hospitals and other critical facilities need to take steps to reinforce emergency power systems and consider options which allow the ability to island these facilities from the grid.

 

Seminar 28: COVID-19 IAQ: Building Readiness and Resiliency in the New Age

Tuesday, June 28 8:00 AM – 9:30 AM EDT

Location / Room: Sheraton Centre Toronto, Dominion South (2)

Summary: We will review what we have learned, what guidelines are in place and concerns moving forward relating to COVID -19 building readiness; COVID-19 mitigation strategies; epidemiology; and occupant trust. This includes analysis of key items from the ASHRAE Building Readiness Guide; a case study discussion of more than 100 buildings risk assessed prior to and after COVID-19 mitigation; a discussion on epidemiology: what we have learned and what studies are still needed and a case study discussion on the role and importance that occupant trust and perception have on the overall success of COVID-19 mitigation: lessons learned from 1990s IAQ.

 

Seminar 52: LIVESTREAM: Without Ventilation Effectiveness, Air Change per Hour Is Just a Number

Wednesday, June 29 11:00 AM – 12:30 PM EDT

Summary: For a long time, air change per hour numbers have been used by designers of different types of buildings, labs, healthcare, cleanrooms, etc. Recent CFD analysis and tests showed that ACR does not guarantee the quality of the interior environments. The effectiveness of the ventilation in the room should be the main concern, but how to evaluate this ventilation effectiveness? The three speakers present their perspective related to the evaluation of the ventilation effectiveness.
