Many activities associated with the construction and habitation of buildings are connected with issues affecting the environment such as global warming, climate change, and consumption of valuable natural resources such as fossil fuels. To minimize negative impacts on the environment, the building industry worldwide has implemented green building practices in many countries. One of the main green strategies is to reduce greenhouse gas emissions caused by residential structures because they are most substantially connected with global warming and climate change. To determine the actual quantity of green house gas emissions caused by the construction and use of a building, it is important to analyze total greenhouse gas emissions over the life cycle of buildings including construction, operation & maintenance(O&M) and demolition stages. Many studies suggest methods to calculate greenhouse gas emissions at the construction stage, but the literature addressing greenhouse gas emissions at the O & M stage is limited. A year-long study was conducted utilizing the deterioration method to calculate greenhouse gas emissions at the O & M stage of building life for condominium types of buildings in South Korea. Through this research, it is possible to analyze greenhouse gas emissions of buildings at the O & M stage, the longest span of the life cycle, and eventually help to calculate total greenhouse gas emissions over the life cycle of the building.

본 논문은 국내 녹색건축물인증제도와 독일의 지속가능한 건축물 인증제도의 평가항목을 비교하여 국내인증제도의 발전방향을 제시하는 것을 목적으로 한다. 오늘날 세계적으로 많은 친환경건축물 인증제도가 시행되고 있으나 상호 비교 가능한 평가항목은 제시되지 않은 상황이다. 이에 국제표준규격에서는 지속가능한 건축물에 대한 평가기준을 마련하였고 독일의 지속가능한 건축물 인증제도는 이러한 평가기준을 받아들인 최초의 인증기준이다. 녹색건축물인증제도를 독일의 지속가능한 인증제도와 비교한 결과 녹색건축물인증제도의 평가내용에는 환경측면(62.6%) 이외의 사회문화와 기능측면(25.4%), 경제측면(3.0%)의 평가항목을 가지고 있는 것으로 나타났다. 이는 앞으로 녹색건축물인증제도의 사회측면 및 경제측면의 평가항목개발에 중요한 방향을 제시한다.

친환경건축물인증 제도는 2002년 첫 시행 이후 2006년부터 인증 획득 실적이 급증하는 추세이며, 이러한 급증은 인센티브 부여, 법적 의무화, 광고효과 등을 통해 이득을 얻고자 하는 발주자가 증가하고 있는 것으로 판단되고 있다. 그러나 친환경건축물인증을 요구하는 발주자의 인증관련 제반 인식과 업무지식 및 역량이 미비한 관계로 인증획득을 위한 개별 의사결정시점과 검토내용을 파악하여 업무를 진행시키기보다 인증획득을 위한 최소한의 조건만을 만족시키고자 하는 발주자가 많은 실정이다. 본 연구는 이와 같은 현황인식에 기반을 두어, 발주자가 인증제도 업무를 명확히 파악하고 적시에 합리적인 의사결정을 수행할 수 있도록 지원하는 관리모델을 제시하고자 한다. 이를 위해 친환경건축물인증 업무를 수행함에 있어서 주요 의사결정이 발생되는 지점들을 게이트웨이로 선정한 후, 시나리오 지향적 프로세스 모델 구현에 적합한 IDEF3 모델을 기반으로 하여 발주자의 업무 지원을 위한 관리체계를 구축하였다. 본 연구에서 제시된 IDEF3 모델기반 관리체계는 단순한 기능분석 위주의 기존 IDEF0 모델의 한계를 극복함으로써 발주자의 인증업무 관련 수행역량 제고를 기대할 수 있을 것이다.

본 연구는 기후변화에 대응하여 2013년 3월 시행된 녹색건축인증기준의 평가항목 및 실제 인증현황 분석을 통해 현행 인증기준의 개선방향 모색을 위한 기초자료를 제시하는 것을 목적으로 한다. 최근 영국 BREEAM, 미국 LEED, 독일 DGNB, 일본 CASBEE 등 선진국의 녹색인증기준은 기후변화에 대응하여 BREEAM Communities, LEED Neighborhood Development, DGNB Stadtquartiere, CASBEE Urban Development로 건축물 중심에서 도시 지구 차원으로 확대하여 시범 운영하고 있다. 이에 반해 국내 인증기준은 건축물 중심의 평가체계로 실내환경 및 에너지 부문의 배점비율이 높고, 외부환경에 해당되는 토지이용 및 교통 부문과 생태환경 부문은 배점비율이 낮다. 실제 토지주택연구원에서 인증을 받은 공동주택 79개 단지에 대한 평가점수를 분석한 결과, 실내환경 및 에너지 등 배점이 높은 평가항목에 따라 인증등급이 결정되어 배점이 낮은 외부환경 부문의 평가항목은 실효성이 없는 것으로 나타났다. 따라서 녹색건축인증기준이 기후변화 대응을 위한 실천수단으로 역할을 하기 위해서는 외부환경 부문의 평가체계를 보완하고, 나아가 국내 현실을 반영하여 도시 지구 차원의 평가체계 도입을 통해 국제적 인증기준에 부합하는 방향으로 개선해야 한다.

The movement towards sustainable building design can result in unique fire protection challenges and concerns, especially with super tall buildings in relationship to traditional prescriptive code compliance. Different countries haves different code requirements as well as local best practices and may cause conflict with the design features when designing green buildings. These include, but not limited to green roofs, sprinkler water quality and testing, fire department access and areas of refuge with direct or indirect impact by the perspective code compliance. The solutions to these prescriptive code challenges and fire safety concerns can range from simple alternatives to more detailed engineering performance-based design analyses with good solid practice.

Environmental problems caused by rapid industrialization and environmental issues have emerged worldwide. The Green Building Certification Policy has been introduced. The purpose of this study is to evaluate the environment-friendly planning factors in Environment-friendly Housing Certification. Six multi-family housing in Environment-friendly Housing Certification have been analyzed. The findings of this study are as follows. While outdoor planning factor is focused on building arrangement and ecological environment, its application in building material and environment plan is inadequate. In ecological environment, various green planting systems such as green zone and plant inhabitation area are utilized.

Since the importance of eco-friendly architecture is rapidly increasing, BIM receives significant attention as an alternative that would derive the practical results and apply the design values of eco-friendly design elements to the architectural design process. Therefore, this study establishes an Integrated Design System based on Green BIM by applying the eco-friendly design values logically and systemically. The study also proposes practical case studies to examine the possibility of application. As a result, the framework of Green based Integrated Design System(gbIDS) and a prototype of Web-based gbIDS were developed to improve the working environment of small architectural firms.

The purpose of this study is to suggest the evaluation standard of cost-effectiveness analysis for renew of architectural equipment in public building. Evaluation items of cost-effectiveness analysis for renew of architectural equipment in public building were used life cycle cost, energy consumption(ton of oil equivalent), green house gas emissions(ton of carbon dioxide) and maximum power demand. Life cycle cost is the process of making an economic assessment of an item, area, system, or facility by considering all significant costs of ownership over an economic life, expressed in terms of equivalent costs. The essence of life cycle costing is the analysis of equivalent costs of various alternative proposals. The social concern with green house gas and maximum power demand of architectural equipment field has been growing for the last several years.

Purpose: This study aims to identify the effect of temperature reduction by the application of cool roof coatings to Changwon City Hall in South Gyeongsang Province. The indoor and outdoor temperatures of the cool roofing building were analyzed and compared to that of an existing building with green-colored roof coated with waterproof polyurethane. Method: The surface temperatures and reflectivity of rooftops, surface temperatures of ceilings and the interior, and outdoor temperature and humidity of the two aforementioned buildings were measured from June to September in 2014. The measurements were taken every 10 min. Result: The surface temperature of the building with the cool roof was lower by a maximum of $9^{\circ}C$ with the reflectivity of the rooftop at an average of 0.55, which is higher than that of the building with green polyurethane by approximately 0.3. The temperature of the ceiling inside the building with the cool roof was about $1{\sim}2^{\circ}C$ lower than that of the ordinary building. Also, the indoor temperature of the office with cool roof coatings was about $0.5{\sim}1.0^{\circ}C$ lower than that of the office with green-colored roofing building. The results show that cool roof coatings can lower the temperature of buildings. In the next research, the reduction in consumption of energy for air conditioning will be investigated by utilizing building energy simulation tools.
