How could Daikin's AC energy efficiency experiment in Osaka affect Kansai?
New AC study may shift regional energy demand patterns for Kansai Daikin's experiment in Osaka demonstrated that continuous air-conditioner operation is often counterproductive, costing about 35 yen more per day compared to switching the unit off when residents leave the room for short periods. This finding, combined with advice that adjusting the thermostat by 4°C to 5.5°C can save up to 10% annually, is likely to increase public awareness of energy waste. As Kansai is a critical power supplier to the Osaka metropolitan area, widespread behavioral changes toward more efficient AC use could lead to shifts in regional electricity demand and grid load management over the long term.

How it reaches Kansai
-
A report debunked the online claim that leaving an air-conditioner running all day is cheaper than switching it on and off. The report states that running the unit continuously generally uses more electricity than switching it off when not needed. This finding is supported by the US Department of Energy and a peer-reviewed study published in 2022.
The full event1independent outlet -
Daikin ran an experiment in Osaka, Japan, finding that while leaving the air-conditioner on for short periods (30 minutes) worked out cheaper, non-stop operation from 9am to 11pm cost about 35 yen more per day than switching it off when residents went out.

The experiment's findings, which also cite that adjusting the thermostat by 4°C to 5.5°C for eight hours a day can save up to 10% a year, are likely to increase public awareness of energy consumption patterns among Kansai's customer base in Osaka. As Kansai is a critical power supplier to the Osaka metropolitan area, changes in consumer behavior—such as reduced continuous AC use—could alter the overall demand and load patterns Kansai must manage.

Why it matters
For Kansai, which functions as a critical power supplier to the metropolitan area of Osaka, managing electricity load is a core operational function. Shifts in consumer behavior, driven by public awareness of energy efficiency, could lead to changes in peak demand times and overall regional consumption, requiring Kansai to adjust its grid planning and resource allocation.
This aligns with broader national efforts to promote energy efficiency, as evidenced by the US Department of Energy's advice that a higher indoor temperature slows the flow of heat into a home. The findings from Daikin's study contribute to the body of knowledge regarding how consumer habits impact energy demand in subtropical climates.
What we don't know yet
- Will the public adopt the recommended thermostat adjustments and usage patterns?
- How quickly would changes in consumer behavior translate into measurable shifts in Kansai's load data?
