Recently, there has been increasing concern for green growth and environment-friendly construction work is being revitalized; hereupon this study is going to understand the present situation of environment -friendly features of the apartment house through the case study of environment-friendly apartment house in and outside the country, and to suggest the developmental direction of the domestic apartment house. First, this study is to look into respective environment-friendly factors by considering the theoretical background of environment-friendliness and certification of environment-friendly structures, and analyzing the cases of apartment house in and outside the country. This study selected as the survey target the apartment buildings located at 5 places which were completed after 2003 and obtained the domestic 'Green Building Certification Criteria'[hereinafter, GBCC] in metropolitan areas in domestic cases and the survey target to the apartment building at 5 places which were completed after 2003 and obtained the US 'Leadership in Energy and Environment Design' [hereinafter, LEED] in overseas cases. For comparative analysis of each case, this study evaluated each case twice using GBCC and LEED to be more objective in evaluation. As a result, it was found that domestic cases focused on nature-friendly landscaping and the use of the certified products while overseas cases focused on minimizing the environmental impact such as raising the energy reduction ratio and reducing water resources and consumption of resources. Accordingly, there seems to be a need for practical energy-reduction & resources-saving scheme in order for domestic environment-friendly apartment buildings to reach the level of the LEED certification.

It is predicted that Japan will be in super-aged society at 2010. Recently elderly house buildings with self-supporting life and personal care senior house types have supplied over the area. So Elderly house buildings in Japan were studied for characters of room arrangement, through documents and internet from Jan. 2007 to Apr. 2007. Five cases built since 2000 were examined. There were self-supporting life house type, personal care senior house type, convenient facilities, etc. There were not lots of facilities in the building. Generally multi-purpose dining room and general bath room, lots for car and bicycle or restaurant or kindergarten or home helper station or green food shop or day service or moving service or clinic were there. These facilities were shared with local community. The reason of not being many facilities in the building was that the houses were located at urban with good transportation and convenient facilities. The residents in the building were get the utmost of regional facilities and the local people did the facilities in it because scare facilities in the building and fluent facilities in region. So strong community was composed of the residents and local people, on the contrary.

Since most Green House Gases (GHGs) and air pollutants are generated from the same sources, it will be cost-effective to develop a GHGs reduction plan in combination with simultaneous removal of air pollutants. However, effects on air pollutants reduction according to implementing any GHG abatement plans have been rarely studied. Reflecting simultaneous removal of air pollutants along with the GHGs emission reduction, this study investigated relative cost effectiveness among GHGs reduction action plans in Busan Metropolitan City. We employed the Data Envelopment Analysis (DEA), a methodology that evaluates relative efficiency of decision-making units (DMUs) producing multiple outputs with multiple inputs, for the investigation. Assigning each GHGs reduction action plan to a DMU, implementation cost of each GHGs reduction action plan to an input, and reduction potential of GHGs and air pollutants by each GHGs reduction action plan to an output, we calculated efficiency scores for each GHGs reduction action plan. When the simultaneous removal of air pollutants with the GHGs reduction were considered, green house supply-insulation improvement and intelligent transportation system (ITS) projects had high efficiency scores for cost-positive action plans. For cost-negative action plans, green start network formation and running, and daily car use control program had high efficiency scores. When only the GHGs reduction was considered, project priority orders based on efficiency scores were somewhat different from those when both the removal of air pollutants and GHGs reduction were considered at the same time. The expected action plan priority difference is attributed to great difference of air pollutants reduction potential according to types of energy sources to be reduced.

We designed a system that can automatically collect, convey, and control cool air of $15^{\circ}C-20^{\circ}C$ containing carbon dioxide from a mushroom cultivation house to a strawberry plastic house. We recorded the temperature at various positions from July to August 2017. The average temperature of the green house during day and at night was maintained at $33^{\circ}C$ and $26^{\circ}C$, respectively. In the moveable three-tier cylindrical bed, the average temperature around root was maintained at $26^{\circ}C$ and $21^{\circ}C$ during day and at night, respectively. On the high-bench in the green house, the temperature was maintained at $32^{\circ}C$ and $30^{\circ}C$ during day and at night, respectively. The carbon dioxide concentration was maintained around 800-1,600 ppm in the mushroom cultivation system and 400-800 ppm in the strawberry plastic house. The growth characteristics of the strawberry treated with moveable three-tier cylindrical bed were significantly different from those of the untreated high-bench bed. In addition, during the summer season, moveable three-tier cylindrical bed showed more tendency to increase in normal fruit number (NFN) and to decrease in defective fruit number (DFN) compare to the high-bench bed. Therefore, the moveable three-tier cylindrical bed showed a tendency to be more than 2 times higher yields than that of the high-bench bed. It was confirmed that ever-bearing strawberry cultivars could be cultivated in green house due to the cool air supply from the mushroom cultivation system in the summer season.

The purpose of the study was to find out the preference of small house as the social relations of university students. The data for the analysis were collected through questionnaire survey method from September 24 to October 12, 2012, and the sample consisted of 283 students of the university in Seoul. The social relationship has been surveyed using modified life-style indicators. The community spaces and equipment in the small house has been divided into 21 community spaces and 3 equipments. The characteristics of small house preference were consisted of the residential comments, residence time, resident partner, house size, considered factors of the residence and small house ownership. The finding of this study were as following: 1) The social relationship of respondents were typed as the type of relationship oriented (oriented family, oriented friends and neighbors) and type of non-relationship oriented. The social relationship of respondents were the type of relationship oriented. 2) The respondents are willing to live in small houses, to live with 1-2 people and after work. When living in small house, they consider public transport accessibility and ease of use amenities. But neighbor relationship is not considered. 3) They are preferred security office, administrative office, home storage, parks and green space.

The green building certification criteria in detached houses in 2012 and it included in the green building certification subject. However, the green building certification result of the detached houses is slight after revising of the system. Therefore, in this research, we were performed the importance analysis for the green building certification assessment of the detached houses. The results of this study will contribute to the green building certification work.

This paper is to clarify a cognitive structure and behaviors of the green environment creation in the Western-Style residential areas. The followings are the results of analysis; 1) Regarding the outside space of houses, yard and garden are differently recognized. While various behaviors are carried out in the yard, the garden is recognized as a space to construct green environment. 2) Most residents of Western-Style houses construct the outside space as a green space, and grow plants and flowers to enjoy their beauties. However they have introvert view of green environment. 3) The roles of outside space use are classified into four groups, the cognitive structures on the green environment creation are different from group to group.
