I am an active member of the American Society for Heating, Refrigeration, and Air-Conditioning (ASHRAE), The International Society of Indoor Air and Climate (ISIAQ), and the American Association of Aerosol Research (AAAR) and am a fellow of ASHRAE and member of the Academy of Fellows of ISIAQ. [...] Of particular importance to this report is the concept of ventilation defined as the “(1) the process of supplying air to or removing air from a space for the purpose of controlling air contaminant levels, humidity, or temperature within the space. [...] Some of the challenges with ventilation include the fact that outdoor air may not be clean of contaminants depending on the location of the building, and in addition to the broader issue of ambient air quality, proximity to major roadways, industrial sites, and other sources of air pollution may require filtration and/or other cleaning of the air in order for it to satisfy the need for ventilation. [...] In order for a mask to effectively protect the wearer, the mask has to have a high filtration efficiency for the droplets/particles that contain the virus and the fit of the mask to the face has to be tight such that air goes through the mask filtration material and not around it. [...] Given the correspondence of some language (e.g., some items in the checklists) in the Ministry Memo with those in the ASHRAE Reopening documents, it seems likely that the Ministry Memo could be easily substituted with the ASHRAE Reopening document to correct the deficiencies and omissions in the Ministry Memo.
