SURVEY ON VENTILATION, INDOOR ENVIRONMENT, AND MEASUREMENT AGAINST COVID-19 IN CLUBS AND BARS (PART 1): OVERVIEW OF BUILDING FACILITIES, VENTILATION CONDITION AND INFECTION STATUS

Abstract

From the early stages of the COVID-19 outbreak, there have been many reports on cluster infections in clubs and bars. Meanwhile, there is no report on the indoor air environment in those places and it will limit measures for infection control. This study aims to understand the indoor air and ventilation environment and to propose practical and appropriate improvement measures for related industries. In addition to measuring CO2 concentration in clubs and bars in Tokyo, we have surveyed the voluntary measures taken against COVID-19, outlines of building and ventilation/air conditioning equipment, ventilation regime, and so on.
