기후조건에 적합한 제주 민가건축의 환경개선 방안에 관한 연구

Abstract

Jeju is an oceanic climate of strong wind and lot of moisture, Korea's southernmost island. In addition, Jeju appears different climate characteristics by altitude and latitude. So, Jeju architectural elements have been developed around a windproof and moisture-proof. But, Jeju rural house was built in recent years, environmental characteristics by legion have been neglected. Jeju rural houses are widely used through the renovation in the suburban areas of Jeju. However, the renovation has been uniformly proceeded without also considering the environmental characteristics by legion. So, Jeju rural houses of today appear easily pollution and damaged material. Not only the interior of the building, leakage, cracking, mold, a number of problems have occurred. This problems is that there is no renovation guidelines and research by regional climate. In this paper, envelope material and indoor thermal condition in rural houses was researched to find ways of improving the Jeju rural houses for Jeju climatic condition. Research on the Building envelope materials has selected a research area by classified climatic condition by the altitude and latitude. And field survey was carried out before checklist was planned focusing on the pollution, damage of envelope materials and renovation. Research result, envelope materials was being improved that the areas receive a lot of influence on the wind is focusing on the roof and the area receives a lot of influence on the moisture is focusing on the walls. The materials of steel folded plate by roof and porcelain, stone tile by walls are mainly used. Most Important element in the building envelope environment was moisture-related factors. So, rainwater and drainage plan should not to contaminate the walls, the building skin with enough sunshine that do not much moisture. research on the thermal condition in rural house has measured two houses each altitude region, total of six houses by temperature and humidity recorder installed in summer and winter Measuring results, indoor temperature was similar to the outdoor temperature or 1~2℃ high in summer. And in winter, indoor temperature was lower than the outdoor temperature by 3~12℃. The rural houses were resolved hot temperature smoothly during the summer by the planing of facing the opening in Jeju architectural features. But, by humidity environment section, mold problem and discomfort, ambitious indoor environment had been created due to the moisture flow. In winter, surface condensation occurs is a main problem by indoor and outdoor temperature difference. The higher or lower indoor temperature of indoor space is a bathroom. And indoor and outdoor temperature difference each houses were different depending on whether the utility space function in Jeju architectural features. As a result, in order to eliminate the moisture of entering into the indoor install the fan in room unit and planning of facing the opening, bathroom and utility room functional differentiation is appeared to be effective in summer. In winter, in order to reduce the surface condensation due to indoor and outdoor temperature difference ensure appropriate standards of thermal insulation, auxiliary heating equipment installation and set up the grade of heating space is appeared to be effective. Through this paper, the judgment will be important resources for planning of renovation and construction guidelines by climatic conditions.
