이 연구에서는 사면과의 부착력과 식물 생장력이 높은 식생기반재를 개발하고자, 시멘트 기반의 결합재와 기능성 첨가제를 혼합한 녹생토의 기초물성과 식물 생장에 미치는 영향을 평가하였다. 석고계 시멘트를 혼합한 녹생토(No.3)의 전단강도가 낮게 나타났으나, 식생 환경에 가장 적합한 경도 수준(23.6mm) 및 pH 값(7.4)을 나타냈다. 또한, 보습제를 첨가하여 성능을 개선한 녹생토의 초기 식생 발현은 일반 녹생토 비해 늦고 전도도값은 다소 높은 경향을 나타냈다. 반면, 성능을 개선한 녹생토는 타설면과의 부착력이 높았으며, 일정 시간 경과 후의 식물 생장 속도 및 동절기와 환절기 재생능력이 우월한 것으로 나타났다.

국내 공동주택의 리모델링 수월성 및 이에 따른 장수명화를 위해 그린 프레임 공법이 개발되었다. 그린 프레임 공법은 합성 프리캐스트 콘크리트 부재를 이용한 라멘구조로 벽식 구조와는 달리 양중 및 설치가 골조공사의 주공정으로 작용한다. 따라서 그린 프레임에 의한 적정 골조공사 공기 산정을 위해서는 체계적인 양중계획이 필요하다. 그러나 양중계획은 그린 프레임을 구성하는 요소인 합성 PC 부재(기둥, 보)의 단위 양중공정에 대한 분석이 선행되어야 한다. 따라서 본 연구는 그린 프레임 합성 PC 부재의 양중공정을 분석하는 것을 목적으로 한다. 이를 위해 합성 PC 기둥과 보의 양중절차와 시간을 도출하고, 그 결과를 사례 프로젝트에 적용하여 기준층의 양중 사이클을 분석한다. 본 연구의 결과는 향후 그린 프레임에 의한 골조공사 양중계획 시 핵심자료로 사용된다.

Recently, As a part of urban forestation, the introductions of green roofs into public projects has been actively driven. Supported by this policy, the sizes of domestic green roof related markets have been rapidly expanding and many types of root barrier materials developed in Korea or abroad are being commercially distributed. In this study, root barrier tests were conducted over two years with nine types of sheet type waterproof materials that are the most commonly used as root barrier layers in green roof systems. The test conditions prepared considered the climates, natural features and vegetation in Korea and the results and related root barrier performance were verified. From the results of this study, the necessity to improve the joint part of root barrier sheets and forming methods has been identified and a measure to improve domestic root barrier testing methods was proposed.

The purpose of this paper is to propose a standard test methods of resistance to root penetration for waterproofing and rootproofing membrane using green roof system. Green roof system is considered to be an important subject in construction industry for green growth project. At the same time, we have to consider the counterplan for protection the damage of waterproofing layer and concrete substrate from the penetration of plant root. But many kinds of materials for protection from root penetration are using in construction field. But the performance of those materials is not clear, and there is not test methods for the evaluation of performance. So in this paper, based on the research results of 4 institutes during four years and foreign cases, we made a standard test methods of resistance to root penetration for waterproofing and rootproofing membrane using green roof system. This test method deals with about environmental condition of laboratory, experimental facilities, kinds of plant, specimen of test, management methods, evaluation duration and documents, etc.

The continuing trend of built environment set forth by the rise of modernization and industrialization has led every country in achieving their respective economic development. Along side this trend is an issue that needs to be addressed - the environmental impacts of the built industry. Construction and maintenance of buildings are said to consume 40% of the world's energy, 65% of electricity, and 40% of raw materials, creating drastic pollutants harmful not only to the environment but also to human. Figures have been released and analyzed proving the contributions of built environment with environmental depreciation. Said figures earned concerns not just from different private and non-profit organizations but also the governments of every country, thus, steps towards sustainable development are being implemented. As a response, the "green" was added in the built environment. Later on, the now emerging concept of "National Green Building Code" found its role in the policy of various states in protecting the people in accord with the nature. This paper appreciates the initiatives of various countries and non-profit organizations in their drive to pursue sustainable green built environment in general, and specifically proposes an establishment of an "incentives grant framework" as an additional legislative policy to be included in the draft of the National Green Building Code of the Philippines.

Since the protection the of human being from natural disaster and atmospheric factors have become an essential requirement, some attempts have been taken place to provide shelter and create a safe environment to a more comfortable life with welfare. For this purpose, using existing resources in nature and exploiting them in a different manner have been taken into account. Initially, the performed exploitations for construction had the least damage to the environment, but over time and as a result of population growth, aggressive exploitation of nature has led to destroying effects on the environment and resulted in consequences such as pollution and environmental destruction. Thus, the construction industry has been identified as the top pollutant factors of the environment. Among various construction factors, the building materials used in this industry are considered as the most important effective factors on the environment, as they have direct influences on the environment from the beginning of construction of the final steps. This research focuses on the review of the most of the existing green materials definitions and various approaches towards using eco-efficient construction materials. It presents and discusses possible ways of reducing the destructive effects on the environment by selecting and using green materials, review current literature and highlight the necessity of applying such materials in future constructions in all communities. This paper provides a base for this purpose that sustainable development communities and environment is realized by elimination of environmental pollution and approaching the criteria of green building by using sustainable materials.

Green building technology has the potential a competitiveness. Reflecting this situation, the renewable energy market is growing rapidly. And, this field became value-added field in construction industry. In this study perform to prioritize the value improvements of green building technologies. To do this, first, we will extract potential development field through literature and case studies. Next, we will built a hierarchy structure based on the economic efficiency, technical skill, and policy. Third, we decide to prioritize between the items by performing AHP analysis.

Korean building industry was developed by concrete and steel construction. However, concrete and steel have some problems which low carbon storage capability and difficulty of recycling. According to many studies, timber has high carbon storage capability, high recycling capability and sustainable supporting capability. Focus on this factors of timber, make new wall structure as Green Timber Wall panels and check the shear performance to use wall system in housing construction such as light-weight timber construction and nondearing wall on other construction. In the results, B-4-B and B-4-S show similar modulus of shear stiffness on the table. GH-4-GH has slip shape failure mode between Green Timber Wall boards. GH-4-GV has most stable characteristic curve than other specimens.

Depot have a lagged behind structure in the side of building up the view. With this reason, people have been recognized depot as hatred facility causes to have car noise, air pollution. In the other hand, depot become a underground and complex facility as a higher-value added building, and moreover, it need to understand the environment that depot structure have a specific field condition to apply green roof system. 1) Analysis proper waterproofing material and root barrier apply to depot need root penetrating test method 2) Suggest root barrier and waterproofing material relate to maintain and construction for green roof system 3) Construction condition for depot have crack movement of structure by vehicle vibration and root penetrating force by plant growth
