On July 2004, the brand new CASBEE for construction (Brief version) has completed while trying to highlight and improve major items adequate for each region's characteristics in Japan; at the same time, from the start of NAGOYA CITY (operated since April 2004) to the point of May 2011, it has been mandatory for specified size buildings in 23 regions by law. Evaluation sheet of CASBEE is published on each region's home page and various genre of information on building evaluation which is scheduled to be completed by 2016 and is for 5-6 years of quantity is accumulated until October 2012. It is good study resource to verify how new buildings being evaluated are closely match with CASBEE's original purport (eco-friendly, energy efficiency, publicity etc). Particularly, for Japan's multi-family housing where small sized mid to high level single housing type is majority in city, it is an important point that improved performance on eco-friendly buildings have more value in city rather than suburb. Categorized score through evaluation is a resource to confirm the latest trend of multi-family housing built in congested city; on the other hand, demand of the time can be recognized by the score focused on category. It is meaningful resource to determine the adequacy of evaluated items and the degree of reality.

"Eco-friendly construction" is an emerging issue in the building industry. Main purpose of the eco-friendly construction is to sustain the health and environment of building residents and to minimize the harmful effect on their environment. Apartment residents have great concern on eco-product, since many cases are reported that Sick Building Syndrome is caused by toxic substance from building materials. Environmental performance is to meet through using the highest grade eco-friendly materials. However, generally eco-friendly materials are more expensive than normal materials, Therefore, using eco-friendly materials at public housing project is limited to economical aspect. The purpose of this paper is development of eco-friendly material selection model considered cost efficiency. The selection of Eco-friendly finishing materials and their methods are constructed to consider environmental performance level and cost index compositively. Development of eco-friendly material selection method is economic and reasonable one when public housing is constructed.

This study basically aims to examine how the GBCC system, which has been implemented since 2005 regarding school facilities, is actually being applied to schools and to survey students' satisfaction and awareness of school facilities. Ultimately, this study is to contribute to improving environment-friendly certification indexes and promoting the system. When it comes to research methods, a school with the green building certification and a school without it were selected for comparison, the two schools were visited for the investigation of their actual conditions, and then, based on the results, a survey was conducted for the students of both schools on their satisfaction(POE) of the school facilities, and finally, the results of the two schools were compared with each other and analyzed. The results of this study shows that the facilities of the school with the green building certification are much superior to those of the school without the certification as well as the former has more various facilities then the latter Nonetheless, facilities with the green building certification were found to miss something in terms of maintenance and management. Most of the survey questions show that students of the school with green building certification have higher satisfaction and awareness levels for school facilities than those of the other school students without the certification. However, the difference was a merely relative one, with most students of the school with the certification answering "so so" for their school facilities in terms of absolute evaluation.

In this study, an analysis has been conducted on the evaluation criteria of current G-SEED(Green Standard for Energy and Environmental Design) and on the 78 buildings, certified by G-SEED, for 3 years from November, 2012 to November, 2015. Based on the results of this analysis, four issues are driven and proposed hereinafter. Issue 1 : Nowadays, the psychological proportion of landscape architecture in building is getting greater than ever so that it shows reliable reduction of carbon dioxide. Therefore, so far as the eight kinds of buildings are concerned, the evaluation items of G-SEED must include those of landscape architecture mandatorily through its enlargement. Issue 2 : It is undesirable factor that inhibits precise evaluation on landscaping area to let other areas appraise landscape architecture because it requires outstanding professionalism. So, G-SEED should not only ensure landscaping professionalism for the correct evaluation but also let landscape area participate in assessing other areas. Issue 3 : Many previous researches turned out that landscape planting technique has excellent effect on saving energy and reducing temperature of buildings. Thus, landscape planting technique of landscape area is required to be one of the evaluation items of energy sector. Issue 4 : Tree management also has to be newly included as one of the evaluation factor for the maintenance relating to the landscape architecture. G-SEED, enacted and enforced by the Green Building Creation Support Act in 2013, surely is effective system to reduce carbon dioxide in buildings. This is a special Act in its nature that is superior to Construction Law and must be observed by all means to construct buildings. Under the umbrella of this legal system, various of researches and products are contributing to creating new jobs in construction area. However, it is a well-known fact that landscape architecture area has shown less interest on this Act than that of construction area. In conclusion, it is necessary that landscape industry should conduct continuous researches on G-SEED and pay more attention to the Act enough to harvest related products and enlarge its work area.

우리나라의 경우 비점오염원에 의한 오염부하 기여도가 점차 증가하면서 '06년 관련 법규 개정을 통해 일정 규모 이상의 개발사업에 대해서는 비점오염저감시설 설치를 의무화하였으며, '11년 기준 국내에는 약 6,000여개 이상의 저감시설이 설치되었다. 해당 시설에 대한 모니터링 결과 장치형에 비해 자연형이 처리효율 및 유지관리 측면에서 유리한 것으로 보고되면서 환경부는 개발사업에 대해 저영향개발기법(LID)의 적용을 의무화하는 방안을 추진 중이다. 개발사업에 있어 LID는 토지이용기법을 통해 우수 유출과 오염원 유출을 저감하고자 하는 기법으로, 비용 및 유지관리 측면에서는 유리하나 기존 단위시설 적용기법에 비해 계획적인 요소가 강해 적용 확대 및 의무화가 용이하지 않은 한계가 있다. 따라서, 본 연구에서는 LID 적용 확대와 관련된 문제점을 분석하고 적용 의무화를 위해 필요한 대안을 모색해 보고자 하였다. 이를 위해 해당 기법 자체가 가지는 한계와 제도적인 문제점을 분석하였으며, LID 기법의 확대 적용을 위해 필요한 대안을 제안하였다. 분석 결과, LID 기법은 기존 장치형 시설에 비해 계획기법의 측면이 커 기술개발이 어려울 뿐만 아니라, 저감시설의 적용여부에 대한 검증도 곤란한 것으로 분석되었다. 또한, 처리효율 계량화가 어려워 오염총량제와 연계된 오염부하 삭감효과 인정이 곤란해 확대 적용에 한계가 있는 것으로 나타났다. 상기의 분석결과에 근거할 때, LID 기법의 확대 적용은 국내의 제도적 여건 및 LID 기법 자체의 한계를 감안하여 단계적으로 추진되어야 할 것으로 판단되며, 조속한 확대 시행을 위해서는 다음의 방안 마련을 제안한다. 첫째, 적용 여부에 대한 판단이 모호한 단점을 보완하기 위해 적정 적용여부를 심의할 수 있는 인증제도 도입을 제안한다. 이 제도는 친환경건축물인증제도 등 기존 유사 제도에 항목을 추가하는 방법과 별도의 제도를 신설하는 방법이 가능할 것이다. 둘째, 처리효율 정량화를 위해 기존 농도 위주의 처리효율 개념을 벗어나 유량 개념의 처리효율 산정이 필요하다. 즉, 처리용량 범위내에서 외부에 유출없이 우수저류 및 침투가 가능한 경우 전량 처리되는 것으로 간주하는 방식이다. 연구결과로 제안한 LID 기법 적용에 대한 인증제도 마련과 유량개념의 처리효율 산정방안이 도입된다면, 보다 조속한 시일내 LID 기법의 확대 적용이 가능할 것이다.

As design tools, building performance certification systems can be applied to provide adequate guidelines on design process to create environment-friendly buildings. Domestic certification systems of residential building took effect by doing supply to designers and contractors from affiliated organization of governments in the early 2000s. As a result, Building Energy Rating System, Apartment Performance Rating System, Green Homes and other means to promote green designs have been operated. International trends of applying certification systems were started in the early 1990s as forms of LEED in USGBC, BREEAM in BRE, GBTool Canada. These systems aim to evaluate building performance in line with the Climatic Change Convention and realize sustainable building design. In 2009, residential buildings accounted for the largest portion of the internal real estate market with 67.9 percent according to the National Statistical Office data. And for 18 years since 1991, apartments among constructed residential buildings have ranked top taking up 77.7% as of 2009. Apartment performance evaluations accordingly are to promote to constitution of improving tenant quality of life, the residential environment and saving energy and resources in the internal building market. The purpose of this study is to compare and analyze valuation bases of each sector in evaluation systems of residential buildings at home and abroad to upgrade current systems through reflecting the characteristics of residential buildings. Implementation of this study basically include comparison of valuation bases and partial analysis on properties of rating systems to suggest requisites for improvement in building performance certification.

The purpose of this study was to learn the lifestyles of college students based on the green building certification system. The importance for environmentally friendly housing patterns will be changed and predicted to provide the basis for future residential development. The subjects of this research were 706 college students living in Jeonbuk province. The results of this research were as follows. College students' lifestyles were measured by self-confidence, family orientation, leisure orientation, economic orientation, and a digital directivity by factor analysis. In eco-friendly residential ratings, as the results of analysis according to the land use, the transportation, the energy resources, the environment load, the ecosystems, the interior environment, and the soundproofing of the interior environment came out to be higher than other factors. While coming out to be higher in the lower group in a digital directivity, the life style of the college students mostly came to be higher in the average of importance for environment-friendly housing. This result means that the college students want environment-friendly housing while attaching importance to the convenience of daily life, especially a digital directivity of housing. Thus, when we plan residences in the future, we will have to reflect the environment-friendly housing on the basis of the results of this research, and improve the environment which is contributing to help form college students' characters well.
