Abstract

The climatic index for tourism(CIT) has recently been advanced, which includes complete human energy balance models such as physiological equivalent temperature(PET) and universal thermal climate index(UTCI). This study investigated human thermal sensation and comfort at Woljung-ri Beach, Jeju, Republic of Korea, in spring and summer 2015 for landscape planning and design in beach areas. Microclimatic data measurements and human thermal sensation/comfort surveys from ISO 10551 were conducted together. There were 869 adults that participated. As a result, perceptual and thermal preference that consider only physiological aspects had high coefficients of determination($r^2$) with PET in linear regression analyses: 92.8% and 87.6%, respectively. However, affective evaluation, personal acceptability and personal tolerance, which consider both physiological and psychological aspects, had low $r^2s$: 60.0%, 21.1% and 46.4%, respectively. However, the correlations between them and PET were all significant at the 0.01 level. The neutral PET range in perceptual for human thermal sensation was $25{\sim}27^{\circ}C$, but a PET range less or equal to 20% dissatisfaction, which was recommended by ASHRAE Standard 55, could not be achieved in perceptual. Only PET ranges in affective evaluation and personal tolerance affected by both aspects were qualified for the recommendation as $21{\sim}32^{\circ}C$ and $17{\sim}37^{\circ}C$, respectively. Therefore, the PET range of $21{\sim}32^{\circ}C$ is recommended to be used for the human thermal comfort zone of beach areas in landscape planning and design as well as tourism and recreational planning. PET heat stress level ranges on the beach were $2{\sim}5^{\circ}C$ higher than those in inland urban areas of the Republic of Korea. Also, they were similar to high results of tropical areas such as Taiwan and Nigeria, and higher than those of western and middle Europe and Tel Aviv, Israel.

최근에 관광기후지수가 생리등가온도(PET)와 범용열기후지수(UTCI)와 같은 완전한 인간 에너지 균형 모델들을 포함함으로써 발전되어 오고 있다. 이 연구는 해변에서의 조경계획 및 설계를 위해, 2015년 봄과 여름에 대한민국 제주특별자치도 월정리해변에서 인간 열환경지수 및 열쾌적성을 조사하였다. 미기후 측정과 국제표준화기구 10551을 바탕으로 만들어진 설문조사를 동시에 실시하였으며, 성인 869명이 참가하였다. 그 결과, 생리적인 요소만 고려된 '열환경 지각'과 '열환경 선호도'가 선형 회귀 분석에서 생리등가온도와 92.8과 87.6%의 높은 결정계수를 나타내었다. 그러나, 생리적 요소와 심리적 요소 둘 다 고려된 '열환경 평가', '열환경 수용도'와 '열환경 부담도'에서는 60.0, 21.1, 46.4%로 낮은 결정계수를 보였다. 그렇지만, 생리등가온도와의 상관성 분석에서는 모두 0.01 레벨에서 유의성이 있는 것으로 나타났다. 인간 열환경 지수를 나타내는 '열환경 지각'에서 덥지도 춥지도 않는 '중간'의 생리등가온도의 범위는 $25{\sim}27^{\circ}C$로 나타났으나, 미국의 냉온난방협회 표준 55에서 추천한 20% 이하의 불만족성 범위는 없었다. 다만, '열환경 평가'와 '열환경 부담도'에서 $21{\sim}32^{\circ}C$와 $17{\sim}37^{\circ}C$의 생리등가온도 범위들이 그 추천범위에 속하는 것으로 나타났다. 그러므로, $21{\sim}32^{\circ}C$의 생리등가온도를 해변지역의 조경계획 및 디자인뿐만 아니라 관광 및 레크리에이션 계획을 위한 인간 열쾌적성 범위로 적용될 수 있을 것이다. 해변에서의 열 스트레스 레벨들은 한국의 내륙들보다 $2{\sim}5^{\circ}C$ 높게 나타났으며, 대만과 나이지리아와 같은 열대지역과 유사한 높은 결과들을 보였고, 서 중유럽과 이스라엘의 텔아비브보다 높은 것으로 나타났다.
