Kruithof demonstrated the preferred combination of illuminance levels and color temperatures. However, as Benett pointed out, difference of themal variables in such preference may be expected. The purpose of this study is to clarify the combined effects of lighting conditions(illuminance, color temperature), operative temperature on the human physiological and psychological responses. In order to observe operative temperature change in preference of color temperatures for three illumination levels, three subjects were exposed to two different conditions of color temperatures of 2,850K, 4,200K and 6,850K combined with operative temperatures(OT)of 25~31℃ at 100~1000㏓. Thermal sensation vote and comfortable sensation vote, brightness perception vote were reported in each experiment conditions. The following results were obtained : 1) When illuminace level was at 100㏓ in operative temperatures of OT20℃, 25℃, 30℃, Color temperature affect not themal sensation but Warm-cool sensation. 2) Operative temperatures affect not brightness perception vote but visual comfort sensation vote, satisfactive sensation vote, warm-cool sensation vote and themal sensation vote.

This objective of this paper is to investigate the evaluation and indiction of human thermal comfort in building environment. The issue of defining the boundaries of acceptable thermal comfort conditions in buildings and urban may have significant implication for building design and also may have urban design by climate considerations. And then it is to apply the thermal comfort condition to environmental design by using passive methods in Korea. Since 1920. architects have conducted studies to measure thermal comfort in houses under hot and humid conditions, while industrial hygienists have studied the effects of temperature and humidity on the performance of factory workers. Thermal comfort can be influenced by many variables. This paper conducted to review the previous researches and the human heat balance equation, and to analyse in order to reveal the meaning and usage of the thermal comfort index in two traditional essays, Fanger's PMV and Gagge's ET Their comfort indexes compared with each other. They were based on human heat balance equation and psychological and physiological responses in the laboratory tests. The researchers and the architectural engineers using thermal comfort index shall be careful in decided the use of indexes and be necessary to recognize the value concept of the design criteria for thermal comfort. Therefore, The opinion of the authors is that different comfort standards have to apply for each building and urban with different climatic conditions.<br/> <br/>

In order to accomplish either information system with future estimate or scientic management, application package of integrated detail management is required for Construction Company. The application package of integrated detail management is based on management of estimation, management of account. management of tax bill, management of on the spot, management of equipment and management of labor. This research focuses on the basic survey for this system such as circumstance of information system for construction company, a barrier of progress, development dirction, development article.<br/> <br/> <br/>

This paper deals with the effects of fluorescent lamp description and luminance level on the occupant's brightness perception and other sensation in building interiors. The following experiments were conducted: the subjects compared on room lit by daylight fluorescent lamps with the other room lit by the different lamp description at equal luminance at equal luminance level. The degree of that effect decreased with a rise in luminace level. The brightness perception had high correlation with the visual clarity and no correlation with favorite sensation.<br/>
