Kyle Hasenkox has worked in the mechanical building services industry since 1998, with various consulting firms in the Victoria area.  He is actively involved in ASHRAE including several Technical Committees including Standard 100- Energy Efficiency in Existing Buildings and 7.5- Smart Building Systems and is current Chair of 9.7 Educational Facilities. Recently, he has been involved in ASHRAE’s Epidemic Task Force- Schools Team which has been generating guidance and reviewing research to help mitigate risks inside educational and recreational facilities. As part of the outreach, Kyle is doing presentations to various groups to present the guidance and provide relevant technical information for designers, operators and other relevant parties.  Title:  Aerosol Mitigation in Schools and Recreation

During this presentation we will review ASHRAE’s recommendations for mitigation of risk due to aerosol spread of SARS-COV2 the virus that leads to COVID Disease.  The World Health Organization has recently identified SARS-COV2 can potentially be transmitted via aerosolized droplets.  ASHRAE’s position document from early this year this states that “Transmission of SARS-CoV-2 through the air is sufficiently likely that airborne exposure to the virus should be controlled. Changes to building operations, including the operation of heating, ventilating, and air-conditioning systems, can reduce airborne exposures.

Statement on operation of heating, ventilating, and air-conditioning systems to

reduce SARS-CoV-2 transmission: Ventilation and filtration provided by heating, ventilating,

and air-conditioning systems can reduce the airborne concentration of SARS-CoV-2 and thus the risk of transmission through the air. Unconditioned spaces can cause thermal stress to people that may be directly life threatening and that may also lower resistance to infection. In general, disabling of heating, ventilating, and air-conditioning systems is not a recommended measure to reduce the transmission of the virus.

In response ASHRAE created the Epidemic Task Force which is broken into a number of work teams with representation from around the globe to gather information,assess risks in the indoor environment including HVAC systems and generate strategies mitigate the spread of the SARS-COV2 Virus.

The session will provide an overview of the risks, options to mitigate risk and help provide some resources from a non bias perspective.  ASHRAE’s intent is to provide an unbiased, fact based perspective and answer questions for relevant parties.

The presentation will cover:

  • Role of aerosols and how they work.
  • Impact of humidity, temperature and activity levels on aerosols
  • Summary of recommended practices and strategies
  • Strategies to develop a response
  • Overview of some disinfection and filtration strategies.
  • Guidance on reopening buildings and free resources available
  • Questions people have in regards to ASHRAE and other material
