Abstract

This study is to develop a GSTM (Green infrastructure Surface Temperature Measurment) equipment for reducing the surface temperature of GI by using LID Method. The tests were conducted including GI products such as Greening block, Pervious Block, Soil Block and so on. The GSTM equipment developed by considering the literature surveys are characterized as follows. The non-contact infrared temperature sensor was used to measure the surface temperature, and it was improved to measure the overall average temperature including the center and the corner temperature of the specimen. The developed GSTM equipment was used to compare performance of asphalt and GI products. As a result, the Greening Block show a high difference of $18.4^{\circ}C$ and it contributes to the decrease of surface temperature.

본 연구는 도시의 열섬을 저감하기 위해 그린인프라시설의 표면온도 저감 성능시험 장비를 개발하고, 대표적인 그린인프라시설 제품을 포함하여 실험을 수행하였다. 기존문헌을 고찰하여 장비를 개발하였으며, 개발된 장비의 특징은 다음과 같다. 표면온도의 측정방법은 비접촉식인 적외선온도센서를 활용하였으며, 시편의 중앙 온도만 측정하는 것이 아닌 모서리 부분 온도를 포함하여 전체적인 평균온도를 측정하도록 개선하였다. 개발된 장비 (GSTM)를 활용하여 대조군인 아스팔트와 그린인프라시설 제품을 비교하여 성능평가를 수행하였다. 그 결과 식생블록이 $18.4^{\circ}C$의 높은 차이를 보이며, 표면온도 저감에 기여하는 것으로 나타났다.
