Existing studies of building exterior materials have focused on the colors or textures of cladding, and in terms of a design planning approach, have focused on the use of the environment and equipment and fire safety topics from an engineering perspective. As a result, little research has been done on performance guidelines for exterior materials, specifically according to the building type. Research into eco-friendly cladding materials is also in the rudimentary stage in a practical sense. In this study, the use of exterior materials over the last ten years in domestic construction was analyzed. The usage status of building exterior materials was evaluated quantitatively by frequency analysis, and its environmental performance is proposed through complex (qualitative + quantitative) analysis. The average value of the exterior material type number used for all analyzed buildings was 2.59. Glass, metal, stone, resin, cement, wood, and clay were used in that order with regard to the usage status. The analysis found that five of the materials satisfied the high efficiency and eco-friendly grading in terms of the four characteristics of an eco-friendly exterior. A list of eight eco-friendly elements was also proposed. The eco-friendly elements and characteristics of the exterior materials were derived to provide basic guidelines for domestic construction companies and design offices.

We developed eco-friendly lightweight concrete in order to apply eco-friendly lightweight concrete into structural wall or slab of shallow depth urban railway system. However, since lightweight aggregate has different structural feature of porous and it has been overvalued at current KS standard when applied, we did compare the characteristics of freezing and thawing of normal weight aggregate concrete by comparative test method(KS, ASTM). According to test method, there was a big difference of dynamic elastic modulus in lightweight concrete rather than in normal weight aggregate concrete. The big absorption factor in lightweight aggregate is main reason for that. For more detail, in KS law in which only 14 days water curing is carried out, the big amount of moisture in lightweight aggregate is frozen and high heaving pressure occurs and finally that lead to destruction of lightweight concrete. Therefore, it is considered that in case of lightweight concrete, resistibility against freezing and thawing has been undervalued in domestic KS law compared to ASTM law, which is overseas standard. So, a variety of examination about testing criteria and rule would be necessary for exact assessment of lightweight concrete.

As more serious environmental problems of buildings, many researchers have recognized the importance of preserving the environment where we live as well as a necessity of developing architecture with eco-environmentally. As a result, our country and some advanced countries have tried to solve these problems in that developed green building assessment tools for estimating environmental performance of buildings. Among many kinds of buildings, hospital which have been relation with human beings has been laking in basic raw materials of researching hospital's environment. Especially, there are few materials about indoor environment of hospital. So, the facilities of patients not only have to depend on the quality of natural environment but be also taken into account of patients. The purpose of this study is to prepare the basic data to develop the items of indoor environmental assessment for hospital to improve the quality of hospital's indoor environment. To come to a conclusion, we used a method of comparing domestic green building certification criteria, LEED v.2.2 and GBTool 2005. Then, we analyzed them for the case studies. Consequently, we could grasp basic data to assist in effecting domestic green building certification criteria for hopital. Furthermore, we have made a progressive research about setting grades of it.

Since artificial building materials and environmental contamination are getting worse recently, people has been interested in eco-friendly construction. In addition, the problems like Sick Building Syndrome are issued these days. In order to solve these problems, the reuse of building materials and the development of environment-friendly materials are urgently in demand. In this sense, Hwangtoh is in the limelight as the environment-friendly material, and broad studies on it have been in progress. However the reactivity of Hwangtoh is low, and without activation process it is very hard to use it as a building material. This study examined the usability of Hwangtoh as an environmental building material by experimenting the reactivity of inactivated Hwangtoh with Reaction Induction Material.

With the signing of the Paris Agreement, which is the new climate change agreement at the end of 2015, it will have a great impact on Korea environmental policy. The construction industry, which accounts for 42% of Korea's total $CO_2$ emissions, has been implementing various policies to improve the environmental problems. However, it is only applying passively to other projects except eco-friendly building certification. This is because most of the eco-related systems are based on building facilities. Therefore, there is a need for a new eco - friendly design evaluation model that can be widely applied not only to architecture but also to civil engineering facilities. In this study, a new model is developed based on the existing VE model, which adds new factors to evaluate the environmental friendliness, potential environmental pollution concept and environmental risk of facilities. This model is an eco-friendly design evaluation model that enables decision makers to effectively select alternative environmental criteria at the design stage. As a result of the case analysis of the block retaining wall and the alternative retaining wall, the value of the eco - friendly value of the alternative was 1.026 times higher than the original one. If this model is used at the design stage, it is expected to contribute not only to the construction of environmentally friendly facilities but also to the reduction of carbon emissions.

Nowadays, according to many studies, indoor space's pollution level is two to ten times higher than outdoor space's. This result arouses our attention. The major causes of deterioration of indoor air quality are the lack of ventilation caused by draught-proofing and insulation construction, and harmful chemical substances emitted from building materials, office machine and furniture. Therefore, we are continuing research to find the method for healthful house and production of many forms of well-being goods. However, because of exaggerated advertisements and the lack of accurate information, consumers choose the products whose performance is not verified. Therefore, this study investigates the actual conditions of pollution by building materials and the extent of the health damage by this pollution, and suggests the method for minimizing indoor pollution in aspect of indoor environment control and the use of environment friendly materials. But the building materials presented in this study are limited to the environment friendly construction materials that are in circulation In domestic market because this research is primarily aimed to give domestic consumers the standard for selecting this materials.
