We will be exhibiting our CO2 sensors and controllers at the 10th Smart Building EXPO within JAPAN BUILD, which will be held next week. This exhibition is one of the largest specialized trade shows in the construction industry, showcasing the latest technologies in IoT for buildings, BEMS, energy-saving air conditioning, and building management systems. When you visit, please be sure to stop by our booth. We sincerely look forward to seeing you. Location: Tokyo Big Sight Dates: December 10 (Wednesday) to December 12 (Friday), 2025, from 10:00 AM to 5:00 PM Booth: 33-25 *Advance registration is required for attendance.

We will be showcasing our CO2 sensor and controller at the "Tokyo Innovation Dissemination Exchange Meeting," where many small and medium-sized enterprises with high technological capabilities, recommended by administrative agencies, will exhibit. Theme: 'Environmental Technology' Exhibition Fields: Upcycling, Biomass, IoT, Energy Conservation, EV, Batteries, Processing Technology, Analytical Technology, Air Conditioning Technology, etc. This is a great opportunity to network with various companies, so please come and visit us.

We are selling CO2 monitors that can be used as a guideline for ventilation at a special price. There are three types available, including models for large spaces and those with data loggers. During the season when air conditioning is used, some people may close windows and stop ventilating. However, neglecting ventilation can lead to an increased risk of infectious diseases, as well as decreased concentration and drowsiness, which can affect work efficiency. Generally, it is said that a comfortable air quality guideline is below 1000 ppm. Please consider this opportunity. *For pricing, please inquire.

We will be exhibiting at the Smart Building EXPO 2024, one of the largest construction industry exhibitions in Japan, featuring 600 companies. ■ Date and Time: December 11 (Wednesday) to 13 (Friday), 2024, 10:00 AM to 6:00 PM (ends at 5:00 PM on the final day) ■ Venue: Tokyo Big Sight, South Hall ■ Booth Number: 24-21 *Advance registration is required for attendance.

The image that ventilation control equals energy saving has not yet become established, so we have created materials that clearly explain the effects and mechanisms. These materials are also ideal for consideration of implementation, so please take a look.

We have released a promotional video for our CO2 controller. It clearly summarizes the mechanism, energy-saving effects, and implementation results, so please take a look.

We hope to continue assisting in creating spaces where music can be enjoyed in a comfortable environment.

We would like to introduce the remote monitoring and control cloud service for indoor environments, 'Marvel IoT,' provided by CHC System Co., Ltd. Through smartphones and PCs, you can remotely monitor the indoor environment of facilities (CO2 concentration, ozone concentration, odor level, temperature, humidity) and remotely control equipment such as ventilation systems. You can remotely monitor the indoor environment, including CO2 concentration and temperature and humidity, in facilities located far away. Based on the accumulated data, we also propose improvements to the indoor environment. Additionally, we will be exhibiting at "HVAC&R JAPAN 2022 (the 42nd Refrigeration, Air Conditioning, and Heating Exhibition)" held at Tokyo Big Sight from February 1 to 4, 2022. For more details, please refer to related products and catalogs.

We would like to introduce one of the largest and most luxurious commercial facilities in Beijing, China, in which our C.H.C. system has participated. The project is named "Lixingxing Center." It began construction in 2014 under the design and supervision of Kengo Kuma, one of the most renowned architects in the world today, and was completed in June 2018. Covering approximately 30,000 tsubo (about 99,000 square meters), it consists of four buildings with a total scale of 100,000 tsubo, making it the most talked-about commercial facility in Beijing. In the summer of 2016, two buildings were completed and are being used as offices for major global corporations such as Hewlett-Packard (HP) and Mercedes-Benz's Beijing headquarters. Finally, at the end of June 2018, the last building was completed, which houses the Hyatt Regency Hotel, set to grand open on November 1, 2018. In this project, we competed with other companies in energy-saving technology and were recognized for our efforts, with a total of 1,300 CO2 sensors and controllers from our company installed in all four buildings. As a result, the philosophy and technology of "energy conservation and comfortable space creation" promoted by the C.H.C. system have been recognized not only domestically but also internationally, allowing us to gain confidence in our future global strategy.

LIXIL Housing Research Institute has announced a new housing concept for the 100-year life era called "Five Generations." The house comfortably connects four households: Unit 1 (85-year-old generation: elderly generation), Unit 2 (65-year-old generation: fulfilled generation), Unit 3 (45-year-old generation: working-age generation), and Unit 4 (25-year-old generation: child-rearing generation). It utilizes IoT technology and is based on concepts such as physical fitness, disaster resilience, and inheritance for the future, proposing evolved housing technology that supports mental connections, health management, and daily living. To create a supportive air environment for health, our "CO2 Controller" has also been incorporated into this concept home as a standard feature of the new housing. The five generations live in separate units suited to each generation while forming a small community under one roof, representing the future of housing, where air quality is maintained and energy efficiency is supported.
