  • 건축물의 에너지 이용을 효율화하기 위하여 단열기준 등을 기존보다 20% 이상 강화하는 것을 골자로 하는 건축물의 에너지절약 설계기준(건설교통부 고시 제2001-118호)이 지난해 6월 1일부터 시행되고 있다. 개정 기준의 가장 큰 특징은 단열기준의 적용 부위를 외기에 직접 면한 부위와 간접 면한 부위로 구분하고, 지역을 중부와 남부, 제주도로 구분$\cdot$설정하여 부하조건과 에너지 소비특성에 따라 건축물의 단열기준을 세분화한 것이다. 특히, 종래에는 최하층 바닥에만 적용하였던 거실 바닥(온돌)의 단열기준을 중간층까지 확대$\cdot$적용하였고, 여기에 온돌시스템의 열적 특성을 고려하여 단열기준의 적용 부위를 보다 구체적으로 설정하고 있다. 따라서 종래의 온돌시스템에서 채움층으로 일반적으로 사용하고 있는 현장 타설식 경량기포콘크리트의 열전도율이 0.13W/mK 내외임을 고려한다면 현행 습식온돌시스템의 열관류율은 $1.0W/m^{2}K$ 이상이 될 것으로 예상됨으로서 앞으로 온돌시스템의 배관층 하부에 $1.0m^{2}K/W$ 이상의 열전도저항을 지닌 단열층이 구성되어야만 개정기준에서 정하는 열관류율 $0.81W/m^{2}K$(기준층 기준)의 성능과 배관하부의 열전도저항값 적용비율을 만족할 수 있을 것으로 판단된다.

  • This research is to measure and analyze the thermal performance of the apartment structure and to evaluate and establish standards of thermal insulation defect in order to make the basic data necessary for determining the degree of the thermal performance degradation and for repairing and reinforcing the exterior wall of the existing apartment. Furthermore, it is to predict the part of occurrence of the thermal bridge and condensation at the apartment building structure. On the other one hand, it is also to analyze the degree of thermal insulation performance according to the standards of thermal insulation and elapsed time, through the analysis by the workability of concrete.

  • Sustainable building is getting more and more important topic in 21C. Following this trend, building energy saving standard has been reinforced in Korea. Especially, insulation standards are revised continuously after1979. This study aims to evaluate the correlation between the revised insulation standards and heating and cooling loads of a residential building. This study shows that the standard of insulation is more related with heating load than cooling load, and cooling load is more related with other sources such as glass types and solar incidence through windows. In case of highly-insulated building such Passive Houses or Zero Energy Houses, the cooling load should also be considered as important as heating load when revising the building energy saving regulations in the future.

  • Recently, the international community signed a climate change agreement to prevent global warming. Yet currently, the fossil fuels have been widely used in to supply building energy for cooling and heating. The Green Building certification (G-SEED), an energy efficiency rating for new or existing buildings requires that buildings meet certain conditions. Insulation is used as a building material to reduce the energy supply to buildings and to improve the thermal insulation, and it accounts for more than 90% of the total heat resistance provided by the building surface components that meet the energy-saving design standards of new buildings. In this investigation, a performance evaluation study was conducted through an experimental study by directly extracting the foam polystyrene insulation on-site during the remodeling of a building that was in the range of 22~38 years old. Through tests, it was found that the thermal conductivity of the extrusion method insulation (XPS) was reduced by 48% and the compressive strength of XPS decreased by 36% compared to KS M 3808, which is the initial quality standard. For bead method insulation (EPS) with a thickness of 50mm, the thermal conductivity, the compressive strength, and flexural failure load were similar to the initial quality standard. Therefore, in the calculation of the primary energy requirement per unit area per year, the performance of bead method insulation can be estimated simply by considering the thickness of the insulation, while a correction factor that considers its performance deterioration should be applied when extrusion method insulation is used.

  • Due to the global warming and energy exhaustion, energy efficiency improvement of construction is recognized the stream of times. To improve the efficiency of the building, in order to energy saving, passive elements should be applied. Then the first step be supposed that applying the new standards about the insulation boundary. The current insulation boundary standards are not reasonable as well as does not divide the purposes. As a result, energy is being wasted and many civil complaints are also occurred. To improve these problems, applying the insulation boundary need to divide the heating and non-heating and subdivide the purpose of construction. In this study, accurate real heating and air conditioning areas are presented that work on the new insulation boundary of purposes and applicable standards. This proposed, by the real heating and air conditioning areas, insulation boundary of purposes, matching the reasonable capacity and load of equipment, by working on standards by optimal maintenance can be energy saving, to present guidelines that environment improvement of actual residents as well as energy saving be expected.
