국토해양부는 지난 10월 20일 20가구 이상의 공동주택을 건설할 경우 총에너지를 종전보다 10~15% 이상 절감토록 하는 내용의 '친환경 주택의 건설기준 및 성능'을 고시하고 이날부터 시행에 들어갔다. 국토부는 친환경적인 주택 건설을 위한 제도적 기반을 구축하기 위해 에너지 소비절감 및 탄소배출량 감소를 위한 에너지절약형 친환경 주택의 건설기준 및 성능을 마련한 것이다. 이 고시는 친환경 주택으로 인정받기 위한 필수시설 및 각각의 설치기준 제시와 에너지 사용용도에 따라 난방, 급탕, 전력, 열원 등 4개로 분류하는 친환경주택 성능 평가방법 등을 규정했다.

최근에는 발생되고 있는 염화물계 제설제의 도로 손상, 차량 부식 및 미끄럼으로 인한 교통사고 문제를 해결하기 위해 친환경 제설제의 사용이 권장되고 있다. 그러나, 현재 수행되고 있는 친환경 제설제의 성능 시험 방법은 실내에서 얼음을 이용하여 실시되고 있으나, 실제 현장 성능과의 상관 관계가 낮은 것으로 나타났다. 따라서 본 논문에서는 현재 수행되고 있는 제설제 성능평가 방법을 소개하고 국내 실정에 부합하는 제설제의 성능 검증을 위한 현장 시험 방법을 제안하고자 한다.

As development of IT technology, Interest of Green building has been increasing rapidly. Because the construction industry is on the center of Green development, Green construction management is demanded for efficient analysis solution of building performance. BIM has a object-oriented parametric modeling technology. IT, which green building's performance management and analysis, is very useful. A green building certification is essential course in the green building construction. So this Paper suggest him based green building simulation system. The him based green building simulation system will support resonable decision making on the early construction phase.

As many countries have been raising awareness of environmental issues, greater efforts for eco-friendly construction have been made in both governmental and private sectors. However, assessment circumstances for building energy performance and green building standard of legislation are still based on two dimension and handwork. This takes time, cost and labor, and makes assessment inaccurate and inefficient. Therefore, this study suggests methods to improve eco-friendly construction permission process and to automatize open BIM-based assessment of Energy Performance Index (EPI) among several eco-friendly construction certification standards. First, it analyzes the relations between assessment criteria and IFC data, and provides solutions to problems and limitations. Second, it applies the solutions to assessment program in order to automatize open BIM-based assessment for EPI. The eco-friendly construction permission process with these solutions applied will reduce time, cost, and labor by simplifying and automatizing the tasks. Also, the simplified process of design revision will improve not only productivity and efficiency but also accuracy and reliability.

This paper aims to provide pragmatic application guidelines of the interior finish materials for apartment houses with newly-established evaluation methodology of the sustainable degree of interior products. With reference to the standards and criteria of domestic eco-labeling accreditation schemes for sustainable products in the area of architecture which focus on the sustainable elements classified as the health, recyclability, durability, and energy efficiency, in this study, a systematic evaluation method has been established for interior finish products with quantifiable indicators for sustainable performance. Base on the evaluation system introduced here, most interior finish products can be classified into a database and applied effectively to the realities from the perspective of the sustainability. There are the necessities of enforcement issues with the idea of revising or taking remedial measures of the current performance criteria of domestic eco-labeling accreditation to bolster their reliability. As well as already-commercialized products, hereafter, continued efforts are needed to control the whole process of manufacturing new interior finish products from their designing, constructing, consuming, recycling and to dismantling in terms of sustainability, which promises more pragmatic follow-up measures for the detail embodiment of the environment-friendly spaces.

As international criteria and standards are required in the fields of design and construction, landscape performance must also be considered not only for the value of the landscape but also for providing quality assurance and sustainability. Given the lack of research on landscape performance, the present research was purposed to analyze the importance of potential assessment categories and items using an analytical network process. A list of assessment items, which is composed of 20 items and 6 categories, was derived through a literature review and a preliminary survey of 11 landscape professionals. An ANP model was established and a survey was conducted among 30 landscape practitioners to determine the weight of priorities considering the criteria. The results of ANP showed that the categories of site selection, preservation and health, and convenience had high priorities while materials had the lowest importance score. For the assessment items, a monitoring plan was the highest importance, followed by cultural/ historic preservation, management cost reduction, and natural ground areas. Despite the difficulties in quantifying landscape achievements, most respondents agreed that there needs to be an evaluation system for landscape performance in order to assure the quality and sustainability of landscape development. More research and discussion are needed to develop an assessment system for landscape performance that is applicable to Korean context.

Hydrazine which has been used as monopropellant shows high performance, but because of its high toxicity research for new green propellant that could replace hydrazine is going on. Ionic liquid propellant that is one of the green propellant has lower toxicity, higher specific impulse, and higher density than hydrazine. To design the thruster which use Hydroxylamine Nitrate (HAN), one of ionic liquid propellant, as a propellant, a quantity of catalyst for full decomposition of a propellant is needed. In this study, reference point for HAN thruster design could be suggested through a design of a small scale thruster which used HAN propellant, and propellant decomposition capability evaluation with characteristic velocity efficiency.
