This study aims to suggest 'an eco-friendly residential housing design guideline as an elderly housing alternative' by mixing the concept of a 'senior citizen community' housing environment with the concept of an 'eco-friendly' housing environment, based on the directivity of an elderly housing alternative for surviving in a super-aged society and the directivity of a sustainable housing environment for providing against global warming. Basically, this study considered the directivity of 'an eco-friendly residential building as an elderly housing alternative' by analyzing housing environment elements and elements to be considered in an elderly housing environment and setting the directivity of an elderly housing environment, which reflects the change in the design paradigm. In relation to the concept of universal design, for considering the perspective of elderly users, existing elements were compared and major planning elements were applied to the scope of complex planning, communal space and housing unit space. In relation to the concept of eco-friendly design, also, a guideline was re-organized and planning elements were applied to each category by comparing domestic and foreign green building certification systems. Based on domestic and foreign authorized guidelines of universal design and green building certification systems, this study was focused on suggesting an eco-friendly residential housing design guideline as an elderly housing alternative to make users perceive the need for a specific indoor environment design guideline and system.

As the environmental pollution is intensified, the interest in the conservation and quality of global environment is also increasing. Interior design affects on environmental conservation as well as the quality of outdoor and indoor environment through all phases of interior design. Therefore, interior designers should do environment-friendly design. The purpose of this study was to examine the consciousness and application degree of environment-friendly interior design in actual project by interior designers. The study was conducted by a questionnaire survey. The subjects were 215 interior designers working in Seoul area. The major findings of this study were as follows: 1) The 33 representative elements of environment-friendly interior design were selected and categorized into 5 fields: resources and materials, energy savings, ecological environments, indoor environments, and space effectiveness. These would be useful to carry out environment-friendly interior design projects and related researches. 2) Many interior designers didn't understand what the environment-friendly interior design is correctly, even though they were interested in it. Therefore, the educational program of environment-friendly interior design should be developed. 3) Even though interior designers thought most elements of environment-friendly interior design very important, they didn't apply them well to actual projects. This implies that alternatives for activating them are needed.

With the IMF crisis in the late 1990's, coupled with the excessive supply of housing stock from the past, construction companies are adopting various differentiating strategies to address the decreasing apartment sales rates. Most of those strategies tend to follow the recent trend of 'eco-friendliness,' creating images of the apartments as 'well-being housing types.' In doing so, green spaces and water features are actively being used in outdoor landscapes design. One specific trend that can be witnessed is the efforts to make reference to the traditional Korean design languages, known as the 'Korean Style.' However, the applications of the 'Korea Style' on landscape design are being explored only by the construction companies, while most researches on the 'Korean Style' focus on its application on the indoor housing units. In this context, this series of case studies of the application of 'Korea Style' on landscape design attempts to extract design elements that can be set as basic guidelines.

Background and objective: With increasing land use intensity in urban areas, apartment buildings have been recognized as a typical type of urban residence. In this study, the impacts of different views through a window on health-related responses were investigated using psychological and physiological parameters. Methods: Photos of three different types of views taken on low (2-12 m), middle (28-35 m), and high (over 54 m) floors of dense apartment building areas were used as visual stimuli. Twenty-two healthy adults participated in the indoor experiment. Semantic differential methods and profile of mood states were used as psychological tools. Autonomic nervous activity was evaluated using blood pressures, pulse rate and heart rate variability (HRV). Results: Analytic data showed different characteristics of psychological and physiological outcomes in three different apartment views. In the analysis of psychological parameters, significantly negative responses to the views on middle floors were found in the subscales of tension-anxiety and anger-hostility, compared to low floors. Significantly positive scores in the subscale of vigor were found on low floors with abundance of vegetation and high floors with a view of the sky. A significantly increased value of HF was found on low floors (2,294.96 ± 169.79), compared to the middle(1,553.45 ± 84.66) and high (1,523.02 ± 70.49) floors. Despite the high scores in openness and vigor, high floor views showed significantly higher LF/HF values (1.83 ± 0.09), the indicator of the sympathetic nervous system, than low (1.30 ± 0.07) and middle floor views (1.34 ± 0.06), which might be related to the unconscious fear of heights. Conclusion: Views from different heights in an apartment building can affect the psychological states of residents. Green space through the window may have a positive health outcome by reducing physiological stress.

Background and objective: Particulate matter (PM) has a fatal effect on health. There have been many studies on the use of plants such as trees and shrubs as eco-friendly and sustainable biofilter for the removal of PM. In forming more green space, ground cover plants play an important role in multi-layered planting. This study was conducted to investigate the ability of plants to reduce PM, targeting Korean native ground cover plants with high availability in urban green spaces. Methods: For 4 species of Asteraceae, 4 species of Liliaceae, and 3 species of Rosaceae, one species of plants at a time were placed in an acrylic chamber (800 × 800 × 1000 mm, L × W × H) modeling an indoor space. After the injection of PM, the amount of PM remaining in the chamber over time was investigated. Results: For all three types of PM (PM10, PM2.5, PM1), significant difference occurred in the amount of PM remaining between plant species after 1 hour in the Liliaceae chamber, 3 hours in the Asteraceae chamber, and 5 hours in the Rosaceae chamber. With Liliaceae, the leaf area and the amount of PM remaining in the chamber showed a negative (-) correlation. With the Asteraceae and Rosaceae, there was a weak negative correlation between the leaf area and the amount of PM remaining in the chamber. Conclusion: When using ground cover plants as a biofilter to remove PM, it is considered effective to select a species with a large total leaf area, especially for Liliaceae.

In this study, the preferences with regard to floral design in a public space and the correlation between such preferences and the image features of the floral design types were identified. Based on the review of the related literature, the floral designs placed in a public space were classified into three types(the flower bed, container, and three-dimensional sculpture types) according to physical factors, and were classified into two types(the indoor and outdoor types) according to environmental factors. In the floral-design type classified by physical and environmental factors, the flower bed and outdoor types, respectively, were highly preferred. The factor that was found to have the greatest influence on the preference for the flower bed type was 'well-orderedness', which included the adjective categories 'harmonious', 'clean', and 'simple'; that which was found to have the greatest influence on the preference for the outdoor-type floral design was 'identity', which included the adjective categories 'symbolic', 'distinctive', 'harmonious', 'impressive', and 'clean'. It can thus be concluded that the plants that are effectively displayed in a public space can express the nature and identity of the city itself, can be a yardstick for giving value to the city and for evaluating it, and can be important components of the urban landscape. A design that is suitable for the purpose of each public space and that reflects the factors that exert an influence on the users' floral-design type preference should thus be developed.

스마트 윈도우는 건물의 에너지 절감을 실현할 수 있는 신소재 건축 자재이며, 상황에 따라 가시광선 투과율(Visible Light Transmittance), 일사획득계수(Solar Heat Gain Coefficient, g-value)를 자유롭게 조절할 수 있는 특징을 가진다. Electrochromic(EC), Suspended Particle Device(SPD), Polymer Dispersed Liquid Crystal(PDLC) 등이 스마트 윈도우에 해당되며 현재 실용화 단계에 있다. 최근 스마트 윈도우의 VLT 및 g-value 조절 기능을 통해 건축물의 에너지를 절감하는 방법에 대한 연구가 활발하게 진행되고 있으며, 일부 유의미한 결과가 도출되고 있다. 하지만, 건축물의 에너지 절감에 대해서 연구의 영역이 제한되어 있고, 실내 환경에 대한 연구는 다소 부족한 실정이다. 에너지 절감에만 초점을 맞춘 실내 공간은 충분한 쾌적성이 확보되지 않기 때문에 실내 환경에 대한 고려가 요구된다. 따라서 이 연구에서는 사무공간을 기준으로 채광성능(Daylight Performance) 분석이 수행되었다. 세계 각 국의 친환경 건축인증제도인 LEED, BREEAM, CASBEE, G-SEED의 기준을 통해 스마트 윈도우의 VLT 조절에 따른 채광성능 검토가 이루어졌으며, 쾌적한 실내 채광환경을 유지할 수 있는 스마트 윈도우의 VLT 범위에 대한 고찰이 이루어졌다. 분석을 위해 사용된 스마트 윈도우는 VLT 조절 범위가 가장 넓은 EC가 사용되었다. 분석 결과 한국의 친환경 건축인증제도인 G-SEED의 평균주광률을 충족하기 위한 스마트 윈도우의 최소 VLT는 25% 이상으로 나타났으며, 스마트 윈도우의 VLT 조절은 균제도에 유의한 영향을 미치지 않는 것으로 나타났다. 또한, LEED의 실내 최소조도의 기준을 적용할 시 적용되어야 하는 계절 및 향에 대한 스마트 윈도우의 VLT 조절 범위 값이 도출되었다.
