This study explored how the elementary schools provided proper interior environments to the students in terms of ecological aspects. 14 cases-7 in Busan and 7 in Osaka which were newly built or remodelled since 2000 were selected. These schools were analyzed based on the eco-school guideline suggested In the former study. The guideline categorizes into three parts: 1) energy efficiency related with lighting, ventilation, heating and insulation, 2) greening, 3) sustainability including recycling water system and use of environmentally friendly materials. The results showed that Korean schools require more systematic planning for natural lighting, ventilation, Insulation, greening and new water system while Japanese schools need use of environmentally friendly materials and consideration for natural lighting, insulation and interior greening. Especially, natural lighting and natural ventilation through roof window, atrium, wind tower and use of natural insulation and blind window system should be basically considered at the Initial planning. Also, this study reveals that ecological approach including greening and natural lighting with various architectural form should be applied in future elementary school design to make the school environment more agreeable and economical.

This study aims to recommend the proper Color rendering index (CRI), the Correlated Color Temperature (CCT), and illuminance levels of Light-Emitting Diode (LED) lighting based on the analysis of the criteria of the current CRI, the CCT, and illuminance levels in merchandising spaces with LED lighting conditions. It would be a basic material to apply in line with user preference for LED merchandising lighting. To this end, it examines relevant literature review on the experiments designed to test whether lighting characteristics affect brightness perception, color appearance, and pleasantness. Highly saturated colors appear brighter than low saturated colors. Two lighting applications - grocery and clothing shop - were created in elaborating the effect of LED lighting characteristics of CRI on color appearance and the CCT and illuminance on pleasantness. The findings show that the criteria of CIE Ra<80 are appropriate to provide better color appearance of illuminated products in terms of LED lighting that can enhance color saturation, particularly for the red color. Furthermore, 2700 K and less than 500 lux for grocery, 4000 K and more than 500 lux for clothing shop are found to be the proper the CCT and illuminance levels respectively to bring better preference under LED lighting.

Lighting simulation is becoming increasingly more important as a method for design and evaluation. There is a wide range of packages that provide the accuracy and the usability in lighting simulation. Relux developed by Relux Informatik AG, Switzerland, Relux offers users innovative and high-performance light planning software with open interfaces and simultaneous access to the latest product data from luminaire and lamp manufacturers. The goals of this report is to explore some of the lighting simulation issues relating to Relux. It is hoped that it will provide some background information that will enable a designer and engineer to make some informed judgements on the potential of the current state-of-the-art in computer prediction of lighting in buildings and how this may be used to assist in building design.

The environmental lighting of a city advances its landscape standards and the city's touristic value because the lighting can help improve the city's safety and security as well as its esthetic value. The types of parks in cities vary in size and function and should be reflected carefully in lighting planning to gain the best effect. The importance of city lighting has been increased in recent years due to the expanded span of urban night life. Lighting systems around rivers and coastal waterfronts in cities play an important role not only in their functional aspects, such as safety and security, but also in boosting the city's identities. This paper performed comparison analysis among Tsim Sha Tsui Promenade in Hong Kong, Fukuoka Nakagawa Park in Japan, and the walking path in Hamdeok Beach in Jeju City, Korea. According to the evaluation, Hong Kong is excellent in 8 evaluation criteria for park lighting so that the city shows its superior installation and management. Fukuoka is also good by being analyzed as 'fair' in 5 criteria. Finally, Jeju is judged as inferior overall by showing 'poor' in several criteria. The paper shows how they differ in their environment lighting characteristics and aims to suggest stable lighting planning strategies for seaside parks in Jeju so the citizens and visitors of Jeju can enjoy the beautiful sceneries and nighttime activities.

This is an interior design for a furniture & lighting design exhibition. The concept of design is to secure the smooth flow planning of an audience and effective direction of an exhibit Design content include 1) installation(passage of light) to guide an audience from entrance to right side of the exhibition space to prohibit the flow dispersion and keep smooth continual circulation flow plan 2)image-wall to introduce exhibition 3)installation to help the global understanding of exhibit 4)exhibition stand design considering proper height of audience's eye.

Recently, there are rapid increases in golf population. People are enjoying play golf not only during the day but also at night as well. Although there are not many golf courses that offer night play, people inquire place where they can play night games due to their busy daily lives. To supply the demand in national golf courses night-lighting has been pushed ahead competitively, however there are few standards of lighting design in golf course. Because it is not clear that the standards of lighting in the world yet, this study aimed at presentation of standard of lighting design for planning golf course. Investigating the cases of golf course, this study suggested illumination standard of golf course to support comfortable visual-environment and measures to prevention glare for visitors.

Illuminance and luminous levels in a small office space due to daylight were calculated to analyze the impact of daylight on contrast and lighting energy savings. Computer simulations were performed for four blind conditions under a clear sky condition. The blind conditions significantly impacted the illuminance an4 luminance level. Visual performance scores were calculated according to the transfer function that uses absolute contrast between target and background surface. The blind condition that had 45 tilted angle toward ground provided good contrast and performance scores. Using a control algorithm of an automated daylight dimming control system lighting energy sayings were predicted. For all blind conditions minimum lighting energy was consumed.

The purpose of this study is to develop the air-conditioning unit combined with the lighting unit for workspace and to supply its performance data at architectural design stage. The air-conditioning unit is one of the components of a workspace integrated unit, which can be defined as the planning unit satisfying the environmental comfort criteria of workspace. Air-conditioning diffusers are classified according to throws and features by literature review and case study. Then diffusers are combined with the lighting unit. Through the CFD simulation, the thermal performance of each unit was evaluated and finally various air-conditioning units combined with the lighting units were developed.
