Based on the trend of architectural lighting of residential building, this study is to examine architectural lighting for residential buildings, and deduce the value and significance of architectural lighting by analyzing architectural lighting and characteristics of residential building through the analysis of works according to the types of works and by analyzing discourse relating to works of architectural lighting of residential building. First, architectural lighting for residential buildings can be categorized according to continuity and extensibility, lighting method and lighting factor. Second, architectural lighting of residential building has come into play since 2000 due to diversified activities at home. Third, architectural lighting had been introduced for living room and used in the form of structure or foundation up until early 2000s, but since mid 2000s, it has been used in intellectual and abstract form using various shapes, finishing material or objects. Fourth characteristic is a space of changing functions overcoming limited space, suggesting an alternative space, and using finishing material and object.

One of the Purposes of architectural lighting is to give pleasure and pride to people. Government often encourages to building owners to apply architectural lighting as a policy because architectural lighting can be one of the tourist attractions. The characteristics of a building, a city and a nation should be reflected to architectural lighting design. Therefore, the purpose of this research is to analyze and compare architectural lighting of buildings in Las Vegas and Shanghai using measured luminance and nighttime image.

Daylighting is core of sustainable design in most buildings. Well-designed daylighting systems can significantly reduce or even eliminate the electric lighting loads during the day time, including air conditioning energy loads. Among window systems. the topside lights systems including monitor lighting, sawtooth lighting, sunscoop and, lightscoop is one of the most popular apparatus to improve the lighting quantity. Also they are important both in terms of energy savings and visual quality. The objective of this study is to analyse daylighting performance of topside lighting system for different orientations. Four types of topside lighting system were tested and comparpd: monitor lighting, sawtooth lighting, lightscoop and sunscoop. Totally 25 measuring points of illuminance on the horizontal plane were monitored from 09:00 to 17:00 on October 6, 2008. Agilent data logger and photometric sensors Li-cor were used. Comparisons with a light factor is discussed. The results found in this study would mean that there were no significant differences in light factor between three cases.

Architectural lighting is an important factor to inform brand image to public for a headquarter building at night The government encourages to clients to apply architectural lighting to their buildings for the nightscape. In these days, variable lightings and lighting designs are applied to a building in the world. Therefore, the purpose of this study is to analyze and compare architectural lighting design on the various office buildings in Hongkong, Shanghai and Seoul with measured luminance and photographic images at night-time.

Today, energy problem has become an important issue, and a development of renewable energy is urgent. In architectural fields, a research of the energy efficient lighting system using renewable energy is in progress. The energy efficient lighting system could be realized by integrating a daylight responsive LED lighting control system and a blind PV system. This system is able to save and generate electric energy. Efficiency of this system depends on control methods of blind PV. As a preliminary research, this research analyzed power generation and inflow of available daylight according to control method of blind PV.

LED lighting has received much attention in recent years due to its high energy efficiency and environmental friendliness. As the color of light can be obtained by adjusting the light intensity of LEDs, the quality of visual environment can be improved. The aims of this study are to develop a wavelength adjustable LED lighting system and to examine its lighting performances. The LED lighting system and experimental cell for assessment of the lighting performance were constructed. This LED lighting system is able to materialize the various spectral power distribution and color temperature of light through the control of the four dimmers. Up to $432^4$ kinds of light combinations are possible. The range of illuminance on workplane were measured as 7~1,831 ㏓. Improvement of psychological and physical functions for occupants can be expected according to control of lighting performances.

Recently, from a saving energy and environmental lighting sources point of view, using LED lighting have been increased rapidly. The colors of light was applied to the control of dimmers that is composed of red, green, blue, and white(RGBW) to improve the quality of visual environment. Moreover this study has been processed to develop adjustable dynamic LED lighting system on SPD and definitize the various spectral power distribution and color temperature of light through the control of the four dimmers. It is possible to combine up to $432^4$ kinds of light. Measurement of illuminance of range on working surface was as 7~l,831 lux. Application of visual environment for occupants can be expected according to control of lighting performance.

Tourist cities as like Las Vegas in USA, Shanghai and Hong Kong in China show various architectural outdoor lighting methodologies and techniques. For these three cities, architectural outdoor lighting methods and techniques were investigated, and the luminous values of advertising illuminants as well as the maximum and minimum luminous values on the walls were measured. Then, based on current CIE luminance standard and IES recommended luminance ratio, characteristics of architectural outdoor lighting in each city are analyzed through the absolute and relative measured luminance values.

Lighting in a fashion shop has an effect on customers, highlights the products on the shelf, and has become more important. Even though lighting has a significant effect on customers, the studies on fashion shop lighting have primarily focused on how to create lighting which can influence customers' purchase behavior, and their awareness and expectation. On the contrary, it's been hard to find a study on a quantified fashion shop lighting plan considering customer confidence. In a current fashion shop lighting plan, display lighting is planned indiscreetly. Therefore, this study conducted an investigation of the light environment of the current fashion shop and museum exhibits lighting. Through such processes, the possibility of applying fashion store display lighting environments was investigated. Finally, for the assessment of museum exhibitions lighting applying fashion store display lighting environments, a subjective evaluation method using light simulation was proposed.

In addition, this study deduced the applicable elements that could be applied in time of building nightscape lighting design using media facade by conducting affective evaluation. The research results are as follows: It was found that the image axis of "Dynamic, Colorful" showed the lighting change speed was fast with diverse application of lighting color, and its evaluation object applied by general emphasis, vertical emphasis, partial emphasis lighting method was highly assessed. In addition, it was found that "Luxurious, Unusual" axis showed lighting change speed was slow with the application of lighting color in warm hue series, and its evaluation object applied by line lighting, dot lighting, general emphasis lighting methods was highly assessed. Lastly, it was found that "Soft, Secure" image axis showed the lighting change speed was slow with the application of pastel tone lighting color, and the evaluation object applied by general emphasis lighting method was highly assessed.
