Frank Lloyd Wright, a master of the 20th Century Ar-chitecture, contributed tremendously in creating a wholly new form of American architecture called Prairie Style. His idea behind the development of the building structur-al system, organic relationships between inner and outer space, horizontal vertical lines, and idea of extending and expanding interior spaces came from nature. He had completed over 390 projects throughout his life and 90% of those projects were residential design. The most typical characteristic shared by many of his residential design was that each design element, whether it is functional or aesthetical, has close relationship to or-ganic nature, human scale, theoretical floor plants, and maximum emphasis on horizontal lines in respect to na-ture. His concept of "flow of spaces" reformed common the-ory of room next to room in a enclosed space. His sense of "wall" was no longer the side of a box. Careful selec-tion of finishing materials, colors, and natural images en-hance the design as well. F.L. Wright was an artist, designer, and architect who believed the exterior space should have direct relationship to the interior space. His architectural philosophy was not only to design exterior of architecture but also to ful-fill his space through the careful development of interior elements such as furniture, and lighting fixture. Even the patterns for leaded glass windows were designed to have unified appearance from outside to inside of the house. The objective of this study was to analyze floor plans, spatial organizations, and interior design elements of the houses which represent the best of F.L. Wright's design principles and philosophy behind Prairie Style. The meth-od used to collect informations for this study was based on books, articles, journals, and actual site visits. actual site visits.

It is necessary to improve the performance of buildings with respect to the energy efficiency while improving the quality of occupants' lives through a sustainable built environment. During the design and development process, building projects must have a comprehensive, integrated perspective that seeks to reduce heating, cooling and lighting loads through climate-responsive designs. The aim of this study is to find an optimal thermal transmittance (U-values) for building envelope elements for low energy multi-rise residential buildings in the early design phase in Korea. The study found that using small U-values of $0.15w/m^2K$ for exterior walls, ceilings and floors and $1.0w/m^2K$ for south and north facing windows has resulted in energy reduction of 22.1%-59.4% in the south facing rooms and 43%-77.6% of the north facing rooms. It has also found the energy load reduction potential of using small U-values are higher on the north facing rooms. The findings of this study can be suggested to be used as a baseline case for low energy consumption studies. It can also be used to determine appropriate envelope materials and insulation values.

This study aims to identify convenient surrounding of the hospital room to be improved by specifically focusing on light environment and to examine a change of inflow of the daylight in the hospital room by using blind and light shelf device as base data of preliminary research for comprehending the relationship between healing environment and natural day light. Simulation analysis on previous facilities and the installation of horizontal light shelf that derives the inflow of day light has been specifically referred by using ECOTECT2011 program. In case of C-facility that mostly adjoined to exterior spaces, it was shown to be closer to a proper uniformity factor when an angle was controlled on the light shelf with blind installed at the same time. However, it was not overall appropriate because of visual displeasure occurred from inflow of much day light. In conclusion, it is the form of flat surface such as H-facility that provides an effect after installing the device to derive day light. Especially, it was shown that interior day light environment was improved when installing blind and controlling the angle at the same time.

Recently, the electronic parts are to be thinner plate, smaller size, light weight material and CPU, HDD and DRAM in all the parts have been produced on the basis of the high speed and greater capacity. Also, conventional goods have replaced a LED (Light-Emitting Diode) in lighting products so; such industry devices need to have cooling. To maximize all the performance on the heat-radiated products, the area of heat-radiated parts is required to be cooled for keeping the life time extension and performance of product up. Existing cooling systems are using radiant heat plate of aluminum, brass by extrusion molding, heat pipe or hydro-cooling system for cooling. There is a limitation for bringing the light weight of product, cost reduction, molding of the cooling system. So it is proposed that an alternative way was made for bringing to the cooling system. EP (Engineering Plastic) of low-cost ABS (Acrylonitrile butadiene styrene Resin) and PC (Polycarbonate) was coated with brass and the coating made the radiated heat go up. The performance of radiant heat plate is the similar to the existing part. We have studied experimentally on the radiated heat plate for the light-weight, molding improvement and low-cost. From now on, we are going to develop the way to replace the exiting plate with exterior surface of product as a cooling system.

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.

Semi-transparent Photovoltaics (STPV) works as an exterior material replacing windows as well as functioning as a electricity generator. As a result, it also affects the building's heating, cooling and lighting loads. In this study, we used the concept of Net Electricity Benefit(NEB) to conduct a parametric analysis of building energy impact of STPV. The NEB of STPV is from $-1kWh/m^2$ to $6kWh/m^2$. Since NEB represents the amount of energy increase or decrease when STPV is applied compared to the standard window, a value of 0 or less means that the demand for building energy can be increased rather than applying a general window having high thermal performance and high visible light transmittance value. Therefore, it is necessary to perform a comprehensive performance evaluation considering both the performance evaluation based on the existing power generation performance and the influence on the building energy.

Today, we are living while interchanging with various countries in multilateral measures and residential culture have been changed while interchanging in the same manner. In order to become an internationally recognized residential environment designer in this environment, we must understand the housing viewpoint of residents in that country first. Therefore, this study is intended to obtain the useful materials for residential environment design of Korea and China by comparing the housing viewpoint between Chinese students studying in Korea and Korean students. A survey using questionnaire was conducted on 205 Korean students and 193 Chinese students (Chinese race) from Y University on a random sampling basis. The result of survey is as follows. First, as both Korean and Chinese university students have a similar tendency on previous house type, current house type, and desired house type, it can be understood that they are similar each other in the experience and preference of house type. Second, Korean and Chinese university students consider and as the most important functions of residence, but Chinese university students consider more functions of residence than Korean students. And, both Korean and Chinese students consider a living room as the most important space among housing spaces, but Chinese consider a private room more importantly than Korean. Third, Chinese university students have stronger desire to possess houses, and desire to purchase houses with larger and more rooms at earlier time than Korean university students. Fourth, when selecting the house, Chinese university students give a higher consideration in terms such as , , , , and than Korean university students. Fifth, satisfaction level of Korean students on current houses was average as a whole, and most Chinese students were generally satisfied with their houses. Sixth, as both of Korean and Chinese university students have higher level of consideration in the items such as safety>, , , , , , , , , , and compared to the level of satisfaction, thoughtful consideration should be given to those items in housing planning.
