On October 12, 2021, the University of Tokyo, Daikin Industries and Nippon Paint Jointly Released a Reference Guide for Educational Facilities on Measures to Reduce the Risk of Respiratory Tract Infections

As a reference material for managers of educational facilities such as schools on how to create indoor environments that are in line with the measures to reduce the risk of respiratory tract infections, including COVID-19, issued by the Ministry of Health, Labour and Welfare (MHLW) and other governmental and administrative agencies, the University of Tokyo (“UTokyo”), Daikin Industries, Ltd. (“Daikin”) and Nippon Paint Holdings, Co., Ltd. (“Nippon Paint”) have jointly formulated and released a reference guide that summarizes specific countermeasures based on engineering demonstrations.

The reference guide is divided into two parts. Part 1 is a “reference guide of measures to reduce the risk of airborne and aerosol infections through ventilation in educational facilities”, aimed at preventing airborne and aerosol infections; and Part 2 is a “reference guide of measures to reduce the risk of contact infections through use of antiviral and antibacterial coatings in educational facilities” to fight infections spread through contact. Part 1 has been developed through the collaboration between UTokyo and Daikin and describes practical measures for ventilation. Meanwhile, Part 2, which has been developed through collaboration between UTokyo and Nippon Paint, focuses on antiviral and antibacterial coatings for indoor surfaces to reduce the risk of contact infections.

The MHLW recommends a ventilation rate of 30 m3 per hour per person as basic infection control measures. Part 1 provides the tips and points to remember for securing the required ventilation volume while maintaining an appropriate thermal environment in the classroom, based on actual measurement survey of the ventilation volume using heat exchange ventilation equipment in classrooms, actual measurement survey of the removal effect of air purifiers on dust simulated as floating viruses, and simulation of the behavior of airflow and floating dust. This reference guide is part of the industry-academia cooperation program, where UTokyo works together with companies on an organization-to-organization basis to share the vision of a future society and promote academic development and social contributions. It is based on the results of the DAIKIN-UTokyo Lab.’s research on airborne and aerosol infection control measures and summarizes specific countermeasures for early introduction into the creation of an indoor environment of educational facilities, such as schools, where students and pupils, the leaders of the future, spend their days.
