The eco-friendly elements are important for new construction and renovation and redevelopment of the buildings. The green buildings are related with minimizing environmental pollution and how to live with nature throughout the entire process of demolishing and building. The purpose of this paper is to study on eco-friendly business buildings in the trend of mandatory green building certification system. The analysis of this paper is comparative studies on practices at eleven domestic eco-friendly business buildings through site survey on design framework of green buildings. The design framework of eleven this buildings is six kinds of skills on technical, renewable, ecological, cultural, healthy, social. The eleven this buildings in the new & renewable energy and IT technology of technical sector are satisfied with the framework. But, domestic most advanced eco-friendly business buildings are placed difference between almost the two times on the lower buildings at comparative evaluation. The three of this buildings are gratified rainwater harvesting and waste recycling systems for renewable and recycle. The buildings have an excellent aspects of technology and ecology. The benefits of this buildings are related with future compulsory zero energy house to take technical advantage of renewable energy. However, the buildings reflecting the regional culture types is insufficient. The buildings should be supplemented as follows. This buildings are need to have the social enhancement programs and design for convenient space of community residents, through health and comfort of on workplace. Moreover, this buildings have features of coexisting with human beings and nature friendly with the aim of realizing the sustainable development. The social enhancement programs through regional cultural aspects with ecology are related with individual and community livings in harmony, non-hierarchical communal lifes. The development of the cultural aspects provide for consensus about the local community and creating sustainable communities. Thus, The buildings are to have energy saving, pleasant and healthy living environment and interactive individual and community livings in harmony.

The urban heat island phenomenon that accelerates global warming has always been controversial when summer heatwaves have occurred since it was first investigated and described by Luke Howard in the 1810s. In Korea, since 2014, government have been interested in Cool Roof and painted white coating on the rooftops of the aging and weak buildings, and the cool roof business has expanded nationwide. However, the roof occupies 20-25% of the entire city surface, much less than 37-45% of the pavement area consisting of roads, parking lots and sidewalks, there is a need to expand the policy of Cool Pavement as a way to reduce the urban heat island phenomenon. Domestic cities are high-rise buildings centered on apartments, and the area occupied by outer walls is larger than that of rooftops compared to foreign low-rise buildings. Therefore, as a way to reduce the urban heat island phenomenon, there is a need for a policy to expand the Cool Roof in buildings and use Cool Wall in parallel. Therefore, this study aims to present the expansion of Cool Wall in buildings and Cool Pavement in urban areas, expanding the installation range of Cool Roof, by comparing and reviewing the thermal characteristics of eco-friendly ceramic coating with excellent thermal proof performance and coatings used for roof waterproofing.

Nowadays, interests on Eco-city planning as Solution for problems of energy demand and environmental change has grown. so Eco-city planning became a major political topic for urban planning and urban design in many advanced nation cities. The purpose of this study is to find out the organized characteristics of Eco-City planning by analyzing successful overseas case where wasted historic port area in city is are regenerated with a environment-friendly concept for Eco-City "HafenCity". It is located on Hamburg-mitte in Hamburg, Germany and is currently the largest construction project in Europe. HafenCity as Home to about 12,000 and the workplace of 40,000 people is being created to accommodate a variety of uses including residential buildings, business, office and retail space as well as cultural and leisure facilities. First of all, HafenCity impresses because of its size as well as because of its Urban planning for eco-city. It presents the excellent change from wasted historic port to the ecological urban space.

최근 국내외적으로 환경문제와 자원고갈에 대한 관심이 높아지는 가운데, 국내 건물부문의 온실가스 배출량은 매년 증가하는 추세이다. 또한 국내 노후화 공동주택이 지속적으로 발생하여 온실가스 증가에 주요원인이 되고 있다. 이는 정부의 2020년 건물부분의 이산화탄소 배출량 저감을 위해 노후화된 설비나 환경개선에 대한 고려가 필요함을 의미한다. 노후화된 공동주택의 개선방법은 크게 재건축과 리모델링 사업이 고려되는데, 온실가스 문제와 함께 친환경성 평가의 중요성이 대두되고, 사업수행시 사업결정의 주요 지표 중 하나로 자리잡고 있다. 본 연구의 목적은 공동주택 주거환경 개선을 위한 두 가지 대안이라고 볼 수 있는 재건축과 리모델링의 친환경성을 비교분석해 보는 것이다. 이를 위하여 본 논문에서는 재건축과 리모델링사업의 특성을 파악하고, 친환경성 비교를 위해 단계별로 동일한 조건을 설정하여, 전생애주기 친환경성 평가와 그 의미를 해석해 보았다. 연구결과로 전생애주기의 LCA 평가를 하였을 때, 대안A(재건축)대비 대안B(리모델링1)의 $CO_2$발생량 차이는 95.85%로 약 4.1% 정도의 $CO_2$감소효과를 얻는 것으로 나타났다. 또한 대안C(리모델링2)의 경우 대안A(재건축) 대비 90.01%로 10%정도 $CO_2$절감 효과를 나타냈다. 또한 단위세대(85m2)를 기준으로 탄소배출권시세를 적용한 결과 대안C(리모델링2)가 대안A(재건축)에 비하여 40만원 정도 환경비용 절감효과가 있는 것으로 나타났다. 따라서 공동주택의 주거환경 개선의 대안을 선택함에 있어서 중요한 근거가 될 수 있을 것으로 판단된다.
