Abstract

This study examines how cooling air conditioner usage behavior and indoor thermal environments in households in Seoul and the metropolitan area have changed over approximately 20 years by conducting the same survey in 2024 as those conducted in the summers of 2004 and 2007. These surveys investigated RAC (residential air conditioner) usage patterns for cooling and indoor thermal environments in households over 20 years. The results showed that indoor temperatures have decreased over time, with air conditioners being operated at lower temperatures in 2024 than in previous years. Additionally, indoor temperatures remained more stable regardless of outdoor temperature. These findings suggest that cooling control behavior and thermal environment have changed over the years, likely influenced by technological advancements and personal preferences. This study provides insights into long-term trends in cooling behavior and indoor thermal environments, enhancing understanding of how occupants adjust cooling behavior as influenced by environmental and technological changes.
