Kyoto Nishiki Market Promotion Association (Kyoto City, Kyoto Prefecture; President: Fusao Mita; hereinafter “Nishiki Market”) and Murata Manufacturing Co., Ltd. (Head office: Nagaokakyo City, Kyoto Prefecture; President: Norio Nakajima; hereinafter “Murata”) will carry out a verification test of a system to reduce the risk of COVID-19 infection at market shopping streets through visualization of the concentration of carbon dioxide in the air at the Nishiki Market.

 

AIRSual installation

 

Adequate ventilation is an important measure for preventing the spread of COVID-19, and one of the indicators of adequate ventilation is the concentration of carbon dioxide in the air. However, since carbon dioxide concentrations vary greatly depending on the environment, it is not easy to measure the correct carbon dioxide concentration. Moreover, even if the correct carbon dioxide concentration can be measured, the lack of clear safety standards is a problem.

Murata will install devices at multiple points along the Nishiki Market’s arcades to monitor carbon dioxide concentrations using AIRSual, a spatial visualization solution that visualizes and analyzes carbon dioxide concentrations in real time. Since this service does not require setting according to the environment, the correct carbon dioxide concentration can be easily measured. Also, since Murata uses AI and advanced algorithms to analyze whether the carbon dioxide concentration is trending upward or downward, ventilation can be conducted based on quantitative measurements. The measurement results can be checked at the Nishiki Market Office, and when the standard value is reached, the roof is opened for ventilation.

In the future, the measured carbon dioxide concentration will be visualized so that visitors can check it. Furthermore, crowd sensors will be installed at the Nishiki Market’s entrances to detect crowds and verify the correlation with carbon dioxide concentration with the aim of creating a comfortable market where people can shop with peace of mind. It is also expected that the results of this verification test will be useful for the preparation of an infection prevention guidebook.

Location: Nishiki Market (Kyoto City, Kyoto Prefecture)
Period: December 20, 2021 to March 31, 2022
