Japan New Cooling Tech: AI Cuts AC Energy Consumption
Ito-Yokado, a major Japanese supermarket chain, is leveraging the power of AI to reduce its carbon footprint. In partnership with Kobe University, the company has developed an innovative “AI Smart Air Conditioning System” designed to optimize energy consumption in its stores. This system utilizes AI to analyze data from in-store cameras, thermometers, and other sensors, monitoring factors like customer traffic, temperature, and CO2 levels. By understanding these variables, the AI can dynamically adjust the air conditioning to ensure comfort while minimizing energy use.
This initiative aligns with parent company Seven & i Holdings’ “GREEN CHALLENGE 2050” environmental goals, which target a 50% reduction in CO2 emissions by 2030 and net-zero emissions by 2050. Ito-Yokado is actively collaborating with various companies and universities to achieve these ambitious targets.
The AI Smart Air Conditioning System employs a three-pronged approach:
- Data Generation: Sensors collect real-time data on room temperature and customer flow within the store.
- Learning and Prediction: AI algorithms analyze this data to predict future customer traffic and heat load, enabling proactive air conditioning adjustments.
- Advanced Control: A new control technology developed by Kobe University maximizes cooling efficiency by incorporating outside air and utilizing surplus heat from adjacent areas.
Following a successful pilot program at the Ito-Yokado Hachioji store in January 2024, the company plans to roll out this AI-powered system to approximately 70 stores by fiscal 2025. This move highlights Ito-Yokado’s commitment to sustainability and its innovative use of technology to create a more eco-friendly shopping experience.
