쿨루프의 장점은? | 쿨루프는 건물 지붕면으로 유입되는 태양 복사에너지에 대한 반사율(reflectivity)을 높이고, 흡수된 복사열(radiant heat)을 빠르게 외부로 방출될 수 있도록 방사율(emissivity)을 높인 지붕을 의미한다[12]. 쿨루프는 건물의 내․외부 온도 저감과 냉방에너지 소비량을 절감하는 효과가 있다[13-15]. 또한 옥상녹화와 비교하여 시공 및 유지관리 측면에서 경제적 효과 등이 있다는 장점이 있다[16]. | |
쿨루프의 실내 열환경 개선 효과 정도에 영향을 주는 요인은? | 모든 측정항목에서 쿨루프를 조성한 사무실(ECD)에서 온도가 낮은 것으로 나타나, 쿨루프의 실내 열환경 개선 효과를 확인할 수 있었다. 물론, 국외 선행연구의 결과와는 쿨루프의 효과 정도가 다소 차이가 있었으며, 이는 대상지역의 지리적 위치와 기후 조건의 차이, 쿨루프의 재질, 색상, 실내 환경 등에 영향을 받은 것으로 판단된다. 따라서 본 연구의 쿨루프는 실내 열환경 개선효과가 있으며, 이를 통해 냉방기 사용 절감 등에도 긍정적인 영향을 미칠 것으로 판단된다. | |
쿨루프란 무엇인가? | 최근 도시열섬완화와 실내 열환경 개선을 위해 다양한 방안들이 마련되고 있는데, 그 중에서 건물 지붕면을 반사율이 높은 마감재로 교체하는 쿨루프(cool roof)에 대한 관심이 증대되고 있다[7-11]. 쿨루프는 건물 지붕면으로 유입되는 태양 복사에너지에 대한 반사율(reflectivity)을 높이고, 흡수된 복사열(radiant heat)을 빠르게 외부로 방출될 수 있도록 방사율(emissivity)을 높인 지붕을 의미한다[12]. 쿨루프는 건물의 내․외부 온도 저감과 냉방에너지 소비량을 절감하는 효과가 있다[13-15]. |
