The number of architects who adopt BIM(Building Information Modeling) as the design method are gradually increasing because of its productivity and efficiency. Climate Change and Global Warming lead to legislation of new energy regulations and strengthen existing ones. The current architectural design methods (2D CAD) take a lot of time and effort to verify energy codes and are hard to adjust according to the design changes. The purpose of this study is to show the effectiveness of the BIM in building envelop energy modeling of the housing project. In the process of design method change, We could contribute to increasing productivity and efficiency in building energy verification through BIM because the updated value could be calculated simultaneously without information omission or recalculation process. The procedure for the study is as follows. Using BIM of the Goldin at Essex Crosing Housing Project by Revit 2011 as a case model, this study analyze the criteria for energy plan to conform to the energy code in NYC. The result value from the setting of the Revit model is compared with the reference value required by the NYC Energy Code. Finally, the data from BIM are entered into COMckeck, the energy verification program provided by U.S. Department of Energy, to check whether the building envelope energy performance conforms to NYC Energy Code.

Hereafter, the domestic housing industry has to give consequence to the redevelopment and rebuilding of existing housings rather than the supply by developing a new building site, and now those tendencies are rapidly spreading out. Also, because apartment buildings occupies 50% over of the existing housing, its maintenance, repair, remodeling and reconstruction got to be necessary area for the slumming prevention of a residential area and the disaster prevention occurred by durability lowering of the building. Accordingly, C&D waste is rising largely by reason of demolition works in city is increasing. The right management of C&D waste is being one of very important things, but little research has been conducted to estimate correctly C&D waste. In this study is to suggest standard units of C&D waste which can estimate demolition quantity of apartment. This units can estimate easily and correctly C&D waste in demolition works, also can possible use very important material to carry out policy of national waste management.

Rapidly increasing automobile supply rate according to improved economic level of life makes lack of parking space of apartments. Even though the initial design of parking space compiled with old regulations, it may not observe either new laws or requirement of inhabitants. Even if old apartments have no structural durability problem, outworn facilities and insufficient parking area may be a main reason for reconstruction. It causes waste of national resources and makes recycling issues. Additionally, irregularly parked cars make traffic obstruction to a fire engine and result in many fire accident victims. Parking problems of apartments are not only inconvenience but also serious safety issues. From these points of view, remodeling only for parking area expansion is necessary to avoid overall reconstruction of apartments. The purpose of this study is to suggest a retaining wall selection method for apartments underground parking lots expansion without evacuation of resident people. Effect factors to select retaining wall system are analyzed and weight values are calculated by applying AHP. One selection method of retaining wall is proposed by evaluating applicability and its sensitivity analysis is executed. This selection method is expected to help decision-making of retaining wall system selection.

The energy use of building operational stage is about 25% of total energy supply in Korea. The intensification of insulation at the design stage and the efficient instruments were used to reduce energy use of the buildings. These efforts are limited at the energy saving side, the residents voluntarily participation in the energy-conservation is more effective. To achieve this purpose, energy use information program (of the individual users) has been developed to lead the energy users actively participating in the energy-conservation program to share at the web. Also, by investigating the necessity and the will of usage of the program and applying a pilot program, the collectability of valid data and the usability have been evaluated.

공동주택에서 태양광발전(PV)을 통한 세대 전기에너지 이용은 모듈 설치 면적의 제약으로 인해 전 세대를 대상으로 활용하기에 현실적으로 어려움이 있다. 특히 남향이나 남동, 남서향으로 위치한 거실 창호를 활용하는 경우에도 결정질 실리콘(crystalline silicon) 태양전지 셀로 인한 실내 음영문제 등으로 건물통합형 태양광발전(BIPV) 시스템의 가시성을 확보하는데 한계가 있다. 따라서 이런 문제점을 극복하고자 투광형 비정질실리콘(amorphous silicon) 태양전지를 이용한 발코니창호/커튼월 BIPV 시스템을 구축하고, 테스트베드를 통한 적용성 평가 검증을 수행하였다. 테스트베드는 KCC 중앙연구소 1층 외부 측창에 결정질 BIPV 모듈(A2PEAK 사(社), 최대 출력 210 Wp, W 2,000 mm ${\times}$ H 1,066 mm)과 10% 및 30% 투광형 비정질 BIPV 모듈(Sharp 사(社) See Through type, 최대 출력 135 Wp/123 Wp, W 1,930 mm ${\times}$ H 1,180 mm)을 각각 설치(남서 $30^{\circ}$, 수직 $90^{\circ}$)하여, 2009년 5월에서 8월 사이 4개월에 걸친 모니터링을 통해 실제 발전량 데이터를 확보, 시스템에 대한 분석을 진행하였다. 분석 결과, 설치용량당 일평균 발전량은 결정질형이 1.46 kWh/kWp, 10% 투광형은 1.10 kWh/kWp, 30% 투광형은 0.73 kWh/kWp을 나타내었다. 10% 투광형과 30% 투광형의 모듈 성능 차이는 크지 않으나 발전량에 있어서는 큰 차이를 보였고, 10% 투광형의 설치용량당 일평균 발전량은 경정질형의 75.2% 수준으로 투광형 비정질실리콘 BIPV 시스템의 창호 적용 가능성을 확인하였다. 특히 세대 거실 창호를 통한 가시성 확보는 기존 결정질 BIPV 창호의 단점을 개선하였다. 건자재 일체화로 구축된 가시성확보 BIPV시스템 창호는 단위 세대별 적용이 쉽고, 공동주택에서 PV 시스템의 설치면적을 극대화시키므로 향후 Zero Energy 공동주택 구축에도 활용성이 클 것으로 기대된다.

Since 2002, Korea Government has introduced Green Standard for Energy and Environmental Design Certification for reducing GHG emission in building area. However, total number of G-SEED Certification is only around 1% of total number of approved apartment buildings despite the various boosting policies. In this situation, most boosting policies and policy improvement researches are leaning toward the supplier's aspect. However, comprehensive relation and dynamics between consumer and supplier has to be considered because housing market is operated by market participants' mutual interaction. Therefore, this research presents system dynamics models based on decision making analysis of consumer and supplier in G-SEED Certification apartment building market. Then, this research evaluate the validity of boosting policies using the model. The proposed analysis can assist government to make next G-SEED Certification boosting policy.

According to the building regulation U-value limitation of window is $3.3W/m^2{\cdot}K$ in southern regions, while U-value limitation of wall is $0.35{\sim}0.58W/m^2{\cdot}K$. It means that the energy loss through windows is five times more than it through wall. Therefore, this study analyze how much it has affected building energy rating when the insulation performance of windows and walls is changed by building regulation. In conclusion, in order to obtain 2 rating thermal performance of windows is improved more than 10 percent of U-value limitation and it of wall is improved more than 20 percent. The thermal performance of windows is improved more than 20 percent of U-value limitation and it of wall is improved more than 30 percent to receive 1 rating.
