The main purpose of the CO2 Subcommittee is to consider ways to reduce electricity consumption and introduce renewable energy sources to curb carbon dioxide emissions. To this end, the subcommittee has implemented large-scale equipment renewal work, such as converting lighting to LED and installing energy-efficient air conditioning equipment. The subcommittee also worked to reduce electricity consumption by utilizing cutting-edge technology, such as by cooperating in a demonstration experiment of cutting-edge robotics.
01 Equipment Update
Renewal work on approximately 400 fan coil units completed (March)
The renovation work began in fiscal year 2018. In fiscal year 2020, 416 units were renewed.

LED lighting with motion sensors installed on emergency stairs. It only lights up when it detects someone, and because it is LED lighting, it has reduced power consumption.
ATC hall LED replacement work completed (March)
With the completion of the hall's LED upgrade work, both power consumption and CO2 emissions will be reduced to one-third of the previous level.
02 Verification of power saving in ATC hall
At the ATC Hall, we verified energy-saving methods for setup and removal. Until now, we had only used downlights to save electricity, but as a result of the verification, we found that by using only baton LED lighting (30% illuminance) instead of downlights, we could reduce the amount of electricity used by 21% while maintaining the same illuminance. We will recommend this method to organizers in the future to help reduce costs and improve customer satisfaction.
03 Introduction of renewable energy
The criteria for selecting electricity suppliers for next fiscal year will also include an evaluation of carbon dioxide emissions, and renewable energy will be introduced.
04 Demonstration experiment in the ATC hall
We support demonstration experiments of cutting-edge robotics. As part of this, we conducted an experiment introducing a cleaning robot from SoftBank Robotics in the ATC Hall. This experiment showed that the cleaning time was reduced to one-third compared to when done by humans, making it possible to significantly reduce cleaning time.
05 SoftBank Robotics Cleaning Robot Introduction Seminar
A representative from ATC Hall took to the stage at SoftBank Robotics' seminar on cleaning robot implementation cases, which was attended by around 80 companies. He introduced a demonstration experiment of a cleaning robot as an example of contributing to the SDGs.
FOCUS
It was a very good experience for us to start working towards obtaining Eco Action 21 certification amidst the dramatic change in the situation caused by the spread of COVID-2. By taking on new initiatives, we were able to create favorable conditions for customers who use the hall. The robot cleaning experiment was originally intended to solve issues such as staff shortages, but we also discovered that it contributes to reducing COXNUMX emissions. We will continue to work to create new benefits while being mindful of the environment.
