Summer Air Conditioning Usage Has Become Longer Compared to 10 Years Ago

Oaklawn Marketing Co., Ltd. (Headquarters: Higashi-ku, Nagoya; President and Chairman: Robert W. Roach), which sells the energy-saving compact cooler "COCOHIE," conducted a nationwide survey on changes in summer air conditioning (AC) usage compared to 10 years ago.

The results showed that 40% of respondents answered, "In the past, a fan was sufficient, but now I can't endure the heat without air conditioning." Additionally, 34% said, "I've been using my AC for longer periods," revealing a shift in cooling habits amid recent extreme heatwaves.

Furthermore, a previous customer survey of "COCOHIE R7" purchasers found that the top reasons for purchase were "to stay cool in areas where AC doesn't reach well" (66%) and "because a fan isn't enough" (34%), indicating a growing need for supplementary cooling in specific hot spots, even while using air conditioning.

About 40% Say They Can't Tolerate Heat Without Air Conditioning

By age group, 44% of respondents aged 60s and 70s answered that they "struggle without AC," surpassing the 36% among those in their 30s to 50s, suggesting that older generations feel a greater necessity for cooling.

Among women in their 60s and 70s, 45% said they "struggle without AC," and 44% reported "longer AC usage," indicating a trend toward extended cooling periods.

Primary Use in Bedrooms and Living Rooms

The "Cooling + Personal Cooling" Approach

The "COCOHIE R7" purchaser survey showed top usage locations as "bedroom" (60%), "living room" (33%), and "kitchen" (26%).

Even with AC use, differences in individual heat sensitivity, discomfort during sleep, and heat buildup in kitchens create demand for supplementary cooling in specific areas.

Oaklawn Marketing's energy-saving compact cooler "COCOHIE R8" is used as a personal cooling device that delivers airflow to areas where heat is felt—such as near desks, in kitchens, or beside beds.
