Abstract

This study evaluates the causal effect of South Korea’s Indoor Temperature Compliance Regulation―which requires public buildings to maintain indoor temperatures at or above 28°C during the summer months―on electricity consumption. Temperature Response Function (TRF) and Difference-In-Differences (DID) approaches are applied to hourly metering data for 199 public buildings over the summer of 2022. The empirical results show that while absolute electricity use in regulated buildings increased due to seasonal factors, this increase was significantly smaller than in comparable unregulated buildings―i.e., electricity consumption “increased in absolute terms but not in relative terms.” This mitigating effect is most pronounced during afternoon peak-demand hours and on particularly hot days. These findings imply that the regulation provides a cost-effective, non-price mechanism to manage peak-demand by leveraging an intuitive reference point: indoor temperature.

본 연구는 여름철 공공기관 적정실내온도 준수 규정의 전기 소비 절감 효과를 시간별 마이크로데이터에 온도 반응 함수와 이중차분법을 적용하여 인과적으로 분석하였다. 분석 결과, 규제 대상 건축물의 절대적 전력 소비량은 계절적 요인으로 증가했으나, 비규제 건축물과 비교하면 증가 폭이 유의미하게 억제되었다. 즉, 규제 대상 건축물의 전력 소비가 ‘(절대적으로는) 늘었지만, (상대적으로는) 늘지 않았다.’ 이러한 효과는 전력 수요가 집중되는 오후 시간대, 그리고 집중의 정도가 높아지는 외부 온도가 높은 날에 더욱 두드러지게 나타났다. 이것은 해당 규정이 비용 효과적인 피크 수요 관리 수단이며, ‘실내 온도’와 같은 직관적인 기준점이 효과적인 비가격 메커니즘으로 작동함을 시사한다.
