In this study, we survey the 2 buildings at the Central 1 and 8 buildings at the Central 2, which are divided by each climate region in the rural regions. Major heat loss factors are 47% loss of the outer shell including outer wall, roof, and bottom, 30% loss through window, and 23% loss through crevice wind. We analyze the energy simulation of ECO2 program to construct a zero energy building regarding village hall located in Jung Juk 4-le at Centeral 2. We simulate the primary energy requirement regarding village hall and the simulated results show the $265.3kWh/m^2{\cdot}a$ and it may estimate '2' energy efficiency grade. The energy requirement regarding village hall is the $183.2kWh/m^2{\cdot}a$ when the passive technology are applied in village hall. We research total amount of energy requirement in village hall when the passive and active technologies such as solar cell with 3kW and solar thermal with $20m^2$, geothermal power with 17.5kW. The simulated results show the improved energy efficiency certification grade with $1^{{+}{+}{+}}$ due to the reduced primary energy requirement with 73% when passive technology including 3kW of solar panel is applied and the energy independence rate is 54%, which is estimated to be 4th grade of zero energy buildings. The order of energy consumption are solar panel, solar thermal, and geothermal power under applied passive technology in the building. In order to expand the zero energy building, it is necessary to introduce the zero energy evaluation system in the rural region.

In Korea, the zero energy building was designated as the 7 new industries in the Ministry of Land and the 8 new industries in the Ministry of Industry. In order to maximize the insulation performance of the building envelope, improve the efficiency of building equipment, We are aiming. It is necessary to analyze the energy requirements of the buildings (cooling, heating, hot water supply, lighting, ventilation) of buildings with energy efficiency level of 1++ which is equivalent to the zero energy building certification system in Korea, It is aimed to be used as basic data for the advancement of energy building certification system. Zero Energy Building certification is estimated to be 61 buildings by 2017, and the approximate reference value and the first energy requirement for each of the five loads are calculated considering passive and active aspects. It is difficult to say that it is a clear standard because there is a small sample of data for calculating the load standard. However, it is necessary to interpret various methods in order to upgrade the Zero Energy Building certification standard in the future.

대통령 소속 국가건축정책위원회, 건축정책기본계획, 건축도시공간연구소, 공공건축가. 지금 우리 건축계를 정의하는 중요한 개념들이다. 이 모두 2007년 제정된 건축기본법에 근거한 내용으로서 당시 건설기술 건축문화선진화위원회, 건설교통부, 문화관광부의 '건축문화 선진화전략' 핵심과제였다. 그러나 '건축기본법'이 있어야 한다고 처음 주장한 사람은 김광현 서울대학교 건축학과 명예교수였다. 그가 연구책임자로서 건축기본법의 바탕을 만들었으며, 오늘의 건축계를 정의하는 건축기본법의 틀과 개념 그리고 용어의 설정도 거의 그의 구상에서 나왔다. 대한건축사협회(한명수 명예회장)와 건설기술 건축문화선진화위원회(김진애 위원장)가 이 법 제정을 위해 큰 힘을 기울였다면, 그는 이론적 기틀을 확립한 인물이다. 그는 학계에 있었지만 설계대가 제값 받기에 유독 관심이 많았다. 이유는 학생들이 사회에 나가 전문가로서 좋은 일을 할 수 있는 최대의 근거는 제대로 된 설계대가에 있다는 그의 지론 때문이었다. "학생들을 가르치는 최고의 목표는 그들이 사회에 나가 좋은 대접을 받게 하는 겁니다. 건축계에서 해야 할 가장 중요한 게 뭐냐고 지금 또 묻는다면 단언컨대 나는 제대로 된 '설계대가'라고 말할 겁니다." 김광현 명예교수는 과거 '공공발주사업에 대한 건축사의 업무범위와 대가기준'에서 '친환경건축물, 에너지효율등급' 등 추가업무에 대한 대가를 제대로 받을 수 있게 하자고 주장하고 이를 연구한 책임자이기도 했다. 그는 지금 젊은 건축사 건축교육 저변확대를 위한 '공동건축학교'를 설립해 활발히 운영 중이다. 월간 "건축사"가 국내 건축계 발전을 위해 힘써오다가 작년 2월 정년퇴임한 김광현 서울대학교 건축학과 명예교수를 3월 18일 그의 대학로 연구실에서 만났다. 그는 지난날을 회고하며 건축에 얽힌 이야기와 현재 하고 있는 일, 그리고 구상 중인 향후계획까지 다양한 이야기를 전했다.

Since 2010, enhancement of the building energy efficiency and certification system and public office building should have been acquiring the first grade of Building Energy Efficiency. The Building Energy Efficiency Rating evaluation tool and Dynamic Analysis Energy simulation program for Building Energy Efficiency are widely used. The suitability to those programs have been discussed as a variety of programs have been used accordingly. In this study, evaluated the characteristic of Building Energy Efficiency Rating tool(ECO2) of the business building. At a result, the variables on the Weather Data, building Profile and building Load property in hourly between those Building Energy Efficiency evaluation tools have different.

Purpose: Apartment is a typical residential type in Korea. In the past, apartment types were very monotonous. But today, the types of complex are changed because personal needs have been diversified and personalized. In order to meet those needs, construction companies are constructing various types of apartments. The more apartment types are diverse, the more the energy problems are taken place. So, the purpose of this study is to solve the problem of energy gap in the same complex through improving the thermal transmittance of wall. Method: Heating energy consumption of Building Energy Efficiency Rating System and heating energy usage of apartment show a similar trend on the graph. In order to identify the best position of heating energy consumption difference reduction, we change the building's U-value of front, back, side walls. Result: In the A complex, maximum and minimum heating energy consumption building's shapes are flat. the best efficiency is side U-value change and the worst is front change. In the E complex, maximum heating energy consumption building's shape is tower and minimum building shape is flat. Consequently, the front and back wall performance change was little effect to reduce energy gap, while the change of side wall's U-value show the great reduction between building's energy consumptions.
