  • This study examines the influence of control algorithms on dimming performance to determine appropriate control setting when direct/indirect lighting is controlled by a daylight dimming system. Computer simulation were performed for a small office with double skin envelope under various daylight conditions. A retractable fabric shading and Venetian blind were applied for internal and external envelopes under three CIE standard sky conditions. Unshielded and partially-shielded photosensors were used, and three control algorithms were applied for the sensors. In general, dimming level was too excessive due to the direct impact of light from lighting fixture to the photosensor. Providing insufficient lighting output, the unshielded photosensor completely failed to secure required illuminance under any daylight condition. When a partially-shielded photosensor was applied under clear sky, three setting points functioned effectively. Less sensitivity for the partially-shielded photosensor was effective to control the dimming system optimally with reasonable energy saving. However, the daylight dimming control system for direct/indirect lighting does not appear to be energy effective when photosensors without enough shielded area is installed on ceiling where light from fixtures reaches directly.

  • The relationship between light and space is fundamental In an opera stage design. In contemporary stage design, light, color and space themselves became one of tile most important elements to express and symbolize the content of the opera. This was very different compared to the primitive and medieval opera stage design in the past. The designer tried to represent the same periodical background of the opera with exact replica of the buildings as well as costumes. In comtemporary performance art, light became one the most important aspects in design. Max Keller is one of the living pioneers in stage lighting design. This thesis that is based on his lighting experiments and projects attempts to examine how contemporary stage design and light are applied and what kind of characteristics they have. One of the Wagner's opera, "Tristan und Isolde" was selected to be further analyzed. Three different "Tristan und Isolde" opera stage designs were carefully studied in terms of how three designs are differently constructed for specific same contents of the opera. This sort of comparison study is crucial when there is a strict parameter that is the opera itself. It was found that three opera stages have very different stage designs and unique ways of expressing the opera flow and contents. However, in some parts, very similar lightings were used. This sort of multi-disciplinary study can be helpful to re-think the interior environment by applying light as a fundamental medium.

  • Children develop in direct relation and response to their physical environment, The purposes of this study were to investigate the current interior design conditions of classrooms in kindergarten and to provide interior planning guidelines for children's behavioral and developmental improvement and better educational environment. Data were collected through interview and questionnaire survey. The sample included 239 teachers who were employed in 23 kindergartens located in Pusan. The data were analyzed by using SPSS-PC. The major findings were as follows; (1) Wood and wallpapers which provide various colors and patterns are recommendable as a classroom finish rather than paint which looks monotonous. (2) Teachers preferred 7 or 8 activity centers in classroom and furniture or partition is the best when dividing space. (3) Classroom should be large enough to locate various types of furniture that designed based on child-size and objects to store. (4) Activity centers should be lit by different types of task lighting such as floor lamp and backer to provide sufficient level of light.

  • Computer simulation is one of the most useful techniques to predict daylighting performance and present visual image. In architectural and interior design practice, the Lightscape is commonly used often to produce persuasive images rather than physically accurate results. Therefore, this study is to validity the Lightscape as daylighting evaluation tool, in particularly performance and realistically visualization. For the purpose, an evaluation test model (12.0m$\times$7.2m$\times$3.0m) of side lighting window with lightshelf was selected. A 1:6 scale plywood physical model was made. Under clear sky condition, illuminance of 84 Interior point were measured. Lightscape was run on a 750 MHz Pentium PC running Windows 2000 under the same sky condition. And a photography image was compared to rendering image. The physical results of interior illuminance were within 8% between the scale model and Lightscape simulation. There were no differences between the photograph image and rendering image by Lightscape in the sight. Lightscape as visualization tool for daylighting performance was validated.

  • Light plays an important role in making a continuity of space and in determining the distinctive expression and char-acter of a space. Particularly, the introduction of natural light derives from our esthetic needs, as well as from the fundamental biologi-cal necessities of human beings. And also, adaptation to time and space is the vital factor of human survival and prosperity. Our visual recognition of light is usually formed not only by practical illumination but by analogy, expection and expe-rienced of lighting itself. As the forecase of natural light is (almost) impossible be-cause of variables such as changing weather, reflection rate of light and the patterns of shade, in designing the introduc-tion of daylight, there should be follow-ed careful considera-tion of the adaptation to such variety and the impet-us of light. The research was conducted to mane a contribution to cre-ate more rich and beautiful interior spaces by studying the characteristic of light which is one of the important factors of interior space design, and by inquiring the way to intro-duce light and its effect through the practical examples of Alvar Aalto, Le Corbusier and Louis I. Kahn.

  • Sir John Sonae(1753-1837) was the most original English architect of 19c. his extremely personal style is superficially neo-classical but, romantic or ' picturesque' in its complicated and unexpected spatial interplay. The Soane's style was one of the curiosities of European architecture. Sir John Soane, like mackintosh, was best known for his interior spaces. He used his own house as a laboratory of spatial experimentation to develop his spatial ideas. The objective of this study was to examine his architectural style through his various architectural works and analyze . The Soane's Museum (his house, No.12.13.14 Lincoln's Inn Fields. London, UK) in order to find inter design elements which represent the best of Soane's interior design effects. As a result , this study found that Soane held no theories as to proportion . It gives the conditon of the building's freedom. He shows the ' primitivism facade and the simple neoclassical symmetry exterior arrangement. As interior design elements he used the layered structure, the natural skylight, the pendentive dome, the space in space, the pictures que style. These elements create magical interior space of the Sonane's Museum. THe spatial intrigue is further enhanced by various degrees of lighting that additionally emphasize the three-dimensional quality of the object loaded walls and piers. One can always look through to space beyond many individual object, both horizontally and vertically. These interior elements can be used for the modern interior design development in order to create the expansion of space and the territoriality of space.

  • As sensibility ergonomics are broadly spread, recently in interior design area, interests on roles of sensibility, sensibility effects for users, and etc has been increased. As a study on sensibility design for interior design area, the study applied sensibility ergonomics technique to bathroom interior design. Sensibility ergonomics technique is integrated into each phase of bathroom design process in order to produce 4 design alternatives. Sensibility evaluation on design alternatives was performed for subject of designers, and analyzed the results to show the relationship between sensibility of designers and design factors and to identify characteristics of designer's sensibility structure. The results of the study are as follows. First, it's found that in the bathroom interior design of sustainable concept, uses of bright colors with white tone and floor tile creates positive sensibility responses such as delight, healthiness, spaciousness, and cheerfulness. Second, designers' sensibility structure about sustainable bathroom is composed of three axles, healthiness, eco-friendliness, and refinement. Third, designers think colors of interior and finished materials is most important, and window, artificial lighting, layout, and space size related to those is important too. The process and approach in the study might contribute to building a fundamental of sensibility design research in interior design area.

  • 본 연구에서는 도로터널 조명설계에 있어서 내부조명의 밝기 수준에 영향을 미치는 갱구부 경관을 L20법 측정을 통하여 수치 해석적으로 고찰하였다. 갱문 형식별로 휘도인자를 추출하고 갱구부 주변시설물의 재료적 특성이 미치는 영향을 평가하기 위해서 동영상 휘도계 HI-LAND ELF SYSTEM과 면휘도계 LMK Mobile advanced로 촬영하여 휘도 분석을 하였다. 국내의 터널은 대부분 산악지대에 분포되어 L20각도 내에서 휘도가 가장 높은 하늘이 점하는 비율이 거의 없으며, 터널 입구주변이나 도로노면에 의한 휘도가 대부분을 차지하고 있다. 그러나, L20각도 내에서 갱문의 면적이 넓게 보이는 면벽식의 경우는 주변이나 노면에 비해 밝은 휘도를 나타냄으로서 터널내 경계부 휘도를 높이는 요인이 되고 있으며, 터널 갱구주변의 도로시설물도 휘도에 영향을 미치고 있음을 파악하였다. 따라서, 휘도기반의 터널조명 설계 시 갱문의 형식 및 갱구부 주변시설물에 대한 면적, 재료, 색상 등이 외부휘도에 영향을 미치고 이로 인해 터널 내부조명의 밝기 레벨 설정에 영향을 주는 요인이 되므로 갱구부 경관설계 시 이에 대한 검토가 반드시 필요한 것으로 나타났다.
