The purpose of this study is to analyze 40 certified Education facilities and to find the way to acquire high scores and usefully method. As a result of analyzing the scores of 40 cases, We found the reasons why they had acquired low scores and high scores. Because the part of land use and transport is initial of the projects, this study focus on it and aim to pick out the items requiring improvement for the Education facilities. We expect to be helpful for the next design works through results of this study.

Until now, the eco-friendly construction (green construction) has been focused on reducing environmental impacts in use(operation and maintenance) phase. Considering the environmental influence along the life cycle of construction project, the impact in execution phase is rather lower than that in use phase. However, that impact is thought to be greatly decreased by well-organized activities. Based on its urgency and requirement for timely action, this study aimed to discuss the greenhouse gas (GHG) reduction plan in execution phase from a broad perspective. To achieve this purpose, the green building rating systems in domestic and foreign countries have been reviewed, and the practice in Japan was investigated. In order to improve current on-site greenhouse gas management, the integration among construction phases, participants, and environmental factors, and institutional supports are required as well as the contractor's efforts.

구내통신 인프라는 이용자 시설로서 한번 설치되면 20년 이상 장기간 사용할 뿐만 아니라 건축물에 밀착된 시설이므로 개량개선이 어렵고 많은 비용과 노력이 소요되는 특성이 있다. 특히 증설과 단선된 곳을 찾아 내는 관리상의 어려운 부분이 있다. 이러한 어려운 부분을 해소하며 건물내에서 가상화 컴퓨팅을 활용해 어느 곳에서든지 인증후 자신의 데스크탑 환경을 그대로 사용할 수 있으며, 보안 문제를 물리적 망분리와 함께 가상화로 문제의 해결점을 제시한다.

The purpose of this study is to analyze the usage of eco-friendly elements in Korean traditional architecture to evaluate Hanok(Unjoru and Jinwondang) according to Green Building Certification Criteria(G-SEED). The results of this study were as follows; Unjoru and Jinwondang was not enough to obtain certification points. From Site usage and Traffic category, Jinwondang gets more points than Unjoru. It's because Jinwondang is located in downtown Seoul, so it gets more points of traffic and neighborhood facility. From Energy and Environmental Pollution category, Jinwondang gets more points of energy performance than Unjoru, too. It's because Jinwondang secured insulation performance of wall and windows using insulator and glass. From Resources category, Unjoru gets more points than Jinwondang. It shows that modern Hanok was limited using natural resources. From Ecological Environments category, Jinwondang is located urban area, it's difficult to secure the open space, so Unjoru gets more points than Jinwondang. If Modern Honok installs a system that can getting point and secure insulation performance, it will be certificated according to G-SEED.

Over the world, social demands and concerns of energy and resource depletions and environmental conservation have resulted in many researches and applications on sustainable development and construction. In order to support these demands and concerns, international green building certification systems such as LEED(Leadership in Energy and Environmental Design) and BREEAM(Building Research Establishment Environmental Assessment Method) were developed. In Korea, the green building certification system was introduced in 2000 and widely applied to all types of new buildings in order to induce the diffusion of sustainable buildings on May, 2010. This paper investigates the importance of assessment criteria on multi-unit apartment projects among certification rating systems using the AHP(Analytic Hierarchy Process) method and suggests a new direction on certification assessment standards. For applying the AHP method, the survey of staffs in green building certification consulting companies and architectural design companies was conducted via e-mail. As a result, criteria like energy, indoor environment, land use, pollution control, and ecological environment among 9 main ones turned out important on assessing green building certification at multi-unit apartment projects, while criteria like water resource, transportation, maintenance management, and material and resource did relatively unimportant.

The purpose of this study is to establish the assessment baseline of $CO_2$ emissions from building operations in the view of GHG reduction policy in Korea. The assessment baseline of $CO_2$ emissions shall be used in GHG policy and Carbon Credits in building sectors, but the assessment baseline has not been studied enough or established yet. Also, $CO_2$ emissions from building operations will be variable according to the building occupancy. Therefore the baseline will be different and this study aimed at the establishment of the assessment baseline for residential apartments and office buildings firstly. After reviews of BEER and international standards for building $CO_2$ emissions such as ISO and UNEP-SBCI documents, the analysis of BEER certification data has been pursued for 292 residential apartment complexes and 65 office buildings in South Korea during 2004~2012. As analysis results, the assessment baseline was set to 23.03 $kg{\cdot}CO_2/m^2{\cdot}yr$ or 1.95 $t{\cdot}CO_2/unit{\cdot}yr$ for residential apartment complexes, and 95.91 $kg{\cdot}CO_2/m^2{\cdot}yr$ for office buildings according to the BEER certification basis. Additional assessment baselines were calculated according to year basis, region basis, public and private basis, and GHG policy basis. Finally, the established baseline for residential apartment complexes has been applied for the pilot project in M district, Seoul, and showed 24.97% reduction rate according to the BEER certification basis.

건축을 전공하는 학생들에게 있어서 건축물을 그림과 기호로 표현하는 것은 자신의 의견을 글이나 발표로 표현하는 것과 같다고 할 수 있다. CAD (computer aided design)는 건축물을 표현하는 방법으로 실무에서도 많이 사용되고 있으며, 건축 관련 전공에서는 거의 개설된 과목이다. 건축공학교육인증(KEC2005)에서도 시각표현적인 과목으로 기초과목으로 요구하고 있어서 CAD를 인증교과목으로 개설하고 있다. J대학교 건축공학전공의 건축제도및CAD 수업은 2학점 4시수로 편제되어 있다. 4시간의 수업시간을 가지고 있지만 실습수업이므로 다른 과목에 비하여 상대적으로 적은 편이다. 본 연구는 부족한 수업시수를 보완하고 학생-교수 사이의 피드백을 활성화하기 위해 오프라인(off-line)과 온라인(on-line) 수업을 결합하는 블렌디드 러닝(blended learning)을 적용하고 그 사례를 분석하는 것을 목적으로 한다. 블렌디드 러닝을 위해 온라인에 수업 카페를 개설하고 과제를 제출함으로써 학생들은 시간과 장소에 구애받지 않을 수 있었으며, 교수도 장소와 시간에 상관없이 피드백을 제공하고 활성화할 수 장점을 확인하였다.

Many government in the world have conducted building energy performance certification program to reduce building energy consumption. In this study, a reference building and its HVAC system was modeled, and the energy load and consumption were estimated by the ECO2 program. The software is a simple building energy simulation program based on monthly calculated method. The building energy efficiency rating the the reference building was 1+ under baseline condition. The simulation results showed that the insulation performance slightly affected building energy load and consumption, but light density had a significant effect on them. The application of geothermal heat pumps gave improvement of building energy efficiency rating but it could not make it possible to get zero energy building(ZEB) certification. The ZEB 5 certification could be achieved by using photovoltaics, however getting better grade was difficult. The simulation results showed that the ZEB 4 certification, one grade higher than ZEB 5, could be attained by using more than one renewable energy source such as geothermal and solar energy in this study.

As the exterior of building has been considered one of th important parts, the use of glass that is suitable to express various appearances gets raised. However, windows have 6~7times lower insulating performance than insulated walls. Lately, highly efficient windows are required as the needs for reduction of energy consumption come to the force. Therefore, Nowadays more people use cooling systems in summer, more the use of Low-E glazing is increasing. Because it is good to block Solar Radiant Energy which can cause much of heat loss while cooling system is working. This study measures U-value of the double Low-E glazing window and commonly used single Low-E glazing window. And then the effect of each window on the efficiency rating has been analyzed applying to the certification system of the building energy efficiency rating which has implemented.
