換気 – 日本建築学会.pdf

The Japanese Ministry of Health, Labour and Welfare and the Prime Minister's Office have issued guidelines on preventing the spread of COVID-19, including the importance of ventilation in preventing the spread of the virus. The guidelines recommend opening windows to improve ventilation, especially in enclosed spaces, and reducing the density of people in a given area. The World Health Organization (WHO) also recommends improving ventilation, especially in schools, by opening windows and using air conditioning systems.

The Japanese Society for Heating, Ventilating, and Air-Conditioning Engineers and the Architectural Institute of Japan have issued a joint statement on the importance of ventilation in preventing the spread of COVID-19. They recommend improving ventilation by opening windows, using air conditioning systems, and increasing the amount of outside air introduced into buildings.

The statement also notes that air purifiers may not be effective in removing COVID-19 from the air, and that ventilation is a more effective way to reduce the risk of transmission. The societies plan to provide further information on ventilation and COVID-19 in the future.

In summary, the guidelines and statements emphasize the importance of ventilation in preventing the spread of COVID-19, and recommend improving ventilation by opening windows, using air conditioning systems, and increasing the amount of outside air introduced into buildings.
