  • For the company, the office space is the expensive resource next to human resource. Employees are under the influence of physical characters of the office space. Among them lighting is the most effective factor in physical, biological and psychological for employees. Although there are lots of investments in architectural aspect of the office space, there is almost no investment and consideration about the lighting environment. Therefore this study was trying to find out these things as follow. First, evaluate lighting environment of people who works in the office spaces. Second, find out which factors are more affective in evaluation of lighting environment. And then with these findings this study found what should be considered as important in lighting planning of the office space. As the result of this study, however the majority of the employees are satisfied with current lighting conditions, they are not satisfied with individual operation of lighting. And in office space work type and position changes by age can affect in a large degree more than other factors.

  • Today, apartment is the most common residence type and various behavior occurs in living room space of apartments. Active usage of living room in modem life increases user's desire of wanting a better environment and leads to find various methods such as remodeling. At the point when considering moving or remodeling, this study focuses on the change of lighting color as it is one of the methods for initial stage with moderate price. As living room is easily influenced by lighting, providing active environment to support inhabitant's behavior through the use of various lighting sources will cut down unnecessary remodeling costs and may be the most simple method to actualize lighting environment for inhabitant's behavior. To give change with the least effort, change in artificial lighting environment was attempted with combinations of lighting color and switching on lights according to illuminating location. This study suggested the capability of changing lighting environment of previous living room area by exchanging lighting sources in lighting equipment in order to satisfy the required behaviors of inhabitant.

  • To compare the lighting environment of the living rooms in the apartments in Korea and China, this research conducted a study of the current status, targeting 79 households in Korea and 68 households in China. The results are the following. First, the two nations use mostly fluorescent light as the general lighting for the living room. China, in particular, share of not using the local lighting is very high. Secondly, levels of illumination was measured. The result demonstrates that the brightness of the lighting is higher in Korea compared to China while China demonstrates higher uniformity ratio for the levels of illumination compared to Korea. However, levels of illumination in general are very low in China. Thus, it cannot be concluded that China offers favorable lighting environment. Third, study on the degree of living room lighting's brightness and satisfaction level demonstrates that they are both average in Korea and China. As for the important points for the house lighting, most Koreans cited 'brightness of the lighting' while most Chinese said 'ease of maneuvering'.

  • Lighting control can be categorized into open-loop and closed-loop. For the closed-loop control, illuminance sensors are generally mounted on a horizontal workplane, or the nearest wall/ceiling. As the size and complexity of an indoor space increases, the number of sensors and its corresponding control become complex because illuminance at a certain point is influenced by multiple neighboring lighting fixtures. The open-loop control is disadvantageous because it can't reflect the illuminance level of a workplane. With this in mind, the authors aim to develop an approach where lighting simulation model could predict the illuminance level at any points of interest, hereby replacing illuminance sensors, and lead to electric lighting energy savings. For this purpose, Radiance, one of the most sophisticated lighting simulation tools, was first employed for daylit and electric lighting prediction of a target building. Then, a surrogate model, ANN (Artificial Neural Network) model, was developed for fast computation and optimal control. Unknown parameters, e.g. reflectances of ceiling, floor, walls, transmittance of glass and light loss factor, were estimated. It was found that the calibrated model's prediction is accurate and the proposed approach can save lighting energy by 18.6% for three days' validation period (Mar 9-12, 2020) conducted at the target building.
