Abstract

This study used a building model made up of cement, brick, and wood to measure temperature and relative humidity for 3 days in a closed environment with a diameter of 900 mm, and performed a comparative analysis of the effect of types of building materials on the indoor temperature environment and heat transfer characteristics. The water installed inside the building model represented the person in the room and was used to assess how the environment effects the person. Wooden building model showed the lowest heat loss due to the higher thermal insulation properties than cement and brick buildings. The thermal comfort of each building model was calculated using temperature and relative humidity, and the wooden building model created a more pleasant environment than the cement and brick building models.

본 연구에서는 시멘트, 벽돌, 목재를 이용한 건축모형을 이용하여 직경 900 mm의 밀폐된 환경 속에서 3일간 온도와 상대습도 측정을 통하여 건축소재의 종류에 따른 실내 온도 환경에 미치는 영향과 열 이동 특성에 대해서 비교분석하였다. 건축모형 내부에 설치된 물은 실내에 있는 사람을 나타냈으며 사람에게 어떤 영향을 미치는지 평가하고자 사용되었다. 목조 건축모형은 시멘트, 벽돌 건축물 보다 보온성이 높아 열 손실이 가장 낮은 것으로 나타났다. 각각의 건축 모형의 열적 쾌적성은 온도와 상대습도를 이용하여 산출하였으며 목조 건축 모형은 시멘트, 벽돌 건축 모형보다 더 쾌적한 환경을 조성하는 결과를 도출하였다.
