Available daylight in inside offers comfortable view environment, and psychological and physical advantages to people in a room. Architecture design has need of daylight prediction for reflection efficiently daylight. But it is difficult to predict the illuminance values in daylight system. Using various lighting simulation software is easy and simple, but we can find different results under the same conditions. This study compares with illuminance values from simulation (Lightscape 3.2, RELUX 2007, RADIANCE 3.9) and Mock-up experiment with the same space and parameter of daylight (location of space and window, date, time and sky condition).

주광은 인공광원보다 심리적 안정과 심리적 신체적 건강 측면 등에서 질적으로 우세하며, 작업능률의 향상에 도움을 주는 것으로 알려져 있다. 또한 쾌적한 빛 환경에 대한 재실자들의 요구가 증가하고 있다. 그러나 주광의 양과 질이 항상 일정하지 않아 예측하기가 어렵기 때문에 이러한 주광의 유용성에도 불구하고 건축설계에 주광을 적극적으로 반영하는 경우가 드물다. 본 연구의 목적은 이러한 주광의 성능을 계량화하고 가시화 할 수 있는 다양한 조명시뮬레이션 소프트웨어(Lightscape 3.2, Relux 2007, Radiance 3.9)를 사용함으로 주광을 예측하고, 도출된 결과 값과 Mock-up 실험의 실측값을 비교 분석을 통하여 조명 시뮬레이션 소프트웨어 활용성을 극대화하는 것이다.

Sound insulation performance of a unit cabin mock-up is studied, where two identical rooms simulating cruise ship cabin are installed. STL (Sound Transmission Loss) measurement in the mock-up shows that STL of the partition between rooms is degraded by imperfect door ceiling and gap between wall and floor. It is also observed that gap around lighting and electrical outlet slightly affect the STL in high frequency ranges, since lighting and electrical outlet are supported by mineral wool in the back side due to fire-resistance requirement. Even after all possible gaps are sealed, STL of the partition is found to be lower than that measured in the laboratory by 9 dB. Measurement of SBN (Structure-Borne Noise) reveals that flanking transmission of SBN along the steel deck floor can severely deteriorate STL of the partition. Statistical energy analysis (SEA) of the mock-up confirms importance of the floor SBN control, in which increasing damping is essential to ensure high STL.

보안구역 내의 외곽울타리지역의 경비체제를 인적경비에서 과학화경비로 전환함에 따라 안정된 보안설비의 적정관리를 위한 조명개선이 요구되어진다. 본 논문에서는 효율적인 외곽 감시를 수행할 수 있도록 경비과학화시스템에 적합한 등기구 선정과 균일한 조도환경을 조성하기 위하여 조명설비의 부적절한 적용으로 모니터에 눈부심이 심한 울타리 지역을 선정하여 LED 등의 용량을 변화시키며 등기구의 각도, 등주간의 거리, 등기구의 취부높이 등의 조정에 따른 현장 모의실험으로 감시모니터에 발생하는 눈부심을 해소시키고자 하였다. 또한 모의실험 조건에 따른 CCTV 화면분석과 조도값을 바탕으로 공항 외곽지역과 유사한 조건으로 조명 모델링하고 소비전력이 다른 LED 광원을 이용한 시뮬레이션 실시로 공항 외곽보안설비의 적정운영 위한 조명설계안을 제시하고자 한다.

Innovative daylighting systems in buildings in various climatic zones around the world have been developed under the IEA SHC Task21. The performance assessment were obtained by monitoring the most systems using full-scale test model rooms or actual buildings under real sky conditions. This study aims to analyze the configuration and monitoring system of the nine Mock-up models of the IEA SHC Task21 comparatively. For the purpose, the geometry of the test rooms (length, width, height, window area, glazed area and occupied), reflectance of walls, floor and ceiling, transmittance of glazing (transmittance for hemispherical irradiation, normal irradiation and U-value) were compared. And equipment for measurement (manufacturer, range, calibration, maximum calibration error, cosine response error, fatigue error), and data acquisition system (manufacturer, type, number of differential analogue input channels, A/D converter resolution in bits, data acquisition software) were also analyzed comparatively. Some findings of these experimental methodology of standard monitoring have been proven to be a valuable one for future assessment of advanced daylighting systems in our country.

According to the tendency of energy efficiency and environment-friendly chracteristics, demend of High-efficiency lighting using LED(Light Emitting Diode)are being increased actively and applied in various fields. However, In order to adequate application of LED light sources, it is necessary to lighting environment and luminous characteristics of LED light sources. This Study aims to characterize the work-plane lighting environment by LED light sources comparing with fluorescent light sources which are widely used. For the sake of this study, a fluorescent light source and 5 LED light sources were introduced and luminance and correlated color temperature were measured to evaluate luminance contrast. The experimental model is Mock-up which is $4.9m{\times}7.2m$ with a height of 2.9m. The test room was set up partition and desks. Luminance and correlated color temperature were measured work-plane on the desk which was set up local lighting by the Radiant Imaging ProMetric 1400. The optical characteristics data of LED can give a lot of advantages to design LED lighting appliances. Hereafter, the object of research will be conducted to evaluate effects of LED light sources on working performance, survey of visual performance, preference and physiology of subjects.

A performance delivers the contents and feeling through human bodies and stage settings in the limited space of a stage. Among the stage settings, the lighting creates overall atmospheres effectively according to the situations of the performance such as a time flow, a change of seasons, an expression of the mental state of the performer. As the LED lighting is used more widely, the number and the size of the lighting is being decreased, which makes it possible for various devices to be used. However, just as conventional lighting devices, most of them are fixed. So it is difficult to use them at a blind spot and to replace them. To solve this problem, this article suggests a system which replaces lighting automatically and moves. As it can moved to a spot we want on a rail, and the lighting system can be replaced by itself, it can have various lighting effects, increasing the effectiveness of the performance. Additionally, it can also decrease the danger of a worker operating the lighting device located at a high place. At the mock-up experiment, its mobility and stability on a rail were tested using the wheel of the Modular Robot.
