국토교통부는 '건축물의 에너지절약 설계기준'과 관련해 지난해 9월, 12월 두 차례 개정하고 시행에 들어갔다. 이 기준은 건축물의 효율적인 에너지관리를 위해 열손실 방지 등 에너지절약 설계에 관한 기준, 에너지절약계획서 및 설계 검토서 작성기준, 녹색건축물의 건축을 활성화하기 위한 건축기준 완화 등에 관한 사항을 담고 있다. 특히 9월 개정에서는 LED조명 설치 확대, 에너지성능지표(EPI) 전기부문 검토항목 추가 등 전기부문에 대한 내용이 다수 포함돼 있어 관계자들의 관심이 요구된다. 개정내용 중 전기부문에 대해 자세히 해설한다.

건설교통부 서울지방국토관리청(청장 한기선)에서는 지난 한 해 동안 수도권에 건설 중인 아파트 등 다중이용건축물의 부실시공 방지를 위해 시공실태점검과 기술자교육 등을 실시하고 있으나, 에너지절약 부분에 있어서는 관련법령에 미달되게 적용하는 사례가 반복 지적되고 있어, 설계자에 대한 관련 기준의 바른 이해에 도움이 되고자 알려 드립니다.

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.

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.

This study was done to reduce total energy demand based on resource shortage problems and to provide improvement points for more efficient adjustment of the high insulation standards for saving energy in Korea. The demand sensitivity was fully considered by varying the slope of each building. The energy performance of the building was maximized by the introduction of outdoor air at night. A final low-energy building model was developed with the two measures combined, and the short-term operation of the night-fuzzy ventilation system was simulated. The result showed a reduction of about 6 to 7 percent compared to the base model. The results could have many implications in terms of the need to conduct demand sensitivity analyses in architectural design.

Developed nations have implemented various policies to reduce greenhouse gases since the 1997 Kyoto Protocol in order to minimize the effects of global warming. Korea should also reduce energy consumption in the industrial sector, and the transportation and building sectors in order to achieve its greenhouse gas reduction target of 37 percent compared to the Business As Usual levels. The government implements various laws and regulations for reducing energy consumption. To reduce energy consumption in the building sector, in particular, the Energy Conservation Design Standards are enforced according to the 'Enforcement Support for Green Building Construction'. The amount of electricity used to maintain room temperature at $28^{\circ}C$ in these buildings have a 30% reduction (measured on the walls and rooftop) in power usage compared to buildings not required to meet these standards. Although the effect of these energy savings on landscaping is proven, this demonstration is not effective for energy saving since it is not a suitable method for the 'Energy Saving Design Standards of Buildings'. For landscaping to be effective as far as a component of energy reduction, the perfusion rate of the building should be calculated based on the thermal conductivity of the component materials for the energy saving designs with respect to the basis of Article 14 of the Green Building Act. Therefore, the purpose of this study is to ensure that the planting-based mats currently being widely used in the landscape industry can have insulating performance suitable for the 'Energy Saving Design Standards' of Buildings according to the 'Enable Green Building Construction Methods'.
