Urban environments require careful consideration of numerous design factors in order to provide unique character, attractive settings and amenities, as well as safe surroundings. Appropriate lighting design is one of the factors contributing to successful urban environments. Wellington’s Civic Centre in the heart of New Zealand’s capital city serves as the setting for a case study exploring cre...

The COPE (cost-effective open plan environments) project investigates the effect of open-plan office design on the indoor environment and on the occupant satisfaction with that environment. COPE is sponsored by a consortium of North American public and privatesector organizations and relies on field, laboratory and simulation studies to address design aspects like acoustics, lighting quality, i...

BACKGROUND: The school is one of the most critical social, educational, and training institutions main pillar education in society. Education and, consequently, educational environments have highest effect on mentality, development, growth, welfare, concentration, performance, learning efficiency students. OBJECTIVES: present study aimed to examine effects environmental ergonomics cognition pre...

Energy redistribution path tracing is a recent approach to performing global illumination that combines basic Monte Carlo path tracing with elements of Metropolis Light Transport in order to achieve the advantages of each. The result is an algorithm with reduced variance, better stratification, and the ability to handle direct lighting, indirect lighting, and caustics with a single method. It i...

There are number of software environment available to conduct lighting simulations to support researchers and designers. This paper compares and analyses performance of four lighting simulation programs (AGI32, DIALux, RADIANCE and RELux), which are dedicated to provide physically accurate lighting calculation. Along with the evaluation of modeling ability and software features two significant ...

Several authors have studied the influence of light on both human physiology and emotions. Blue light has been proved to reduce sleepiness by suppression of melatonin secretion and it is also present in many emotion-related studies. Most of these have a common lack of objective methodology since results and conclusions are based on subjective perception of emotions. The aim of this work was the...

Previous work has demonstrated that the image variations of many objects (human faces in particular) under variable lighting can be effectively modeled by low dimensional linear spaces. Basis images spanning this space are usually obtained in one of two ways: A large number of images of the object under different conditions is acquired, and principal component analysis (PCA) is used to estimate...

Lighting accounts for a significant amount of electrical energy consumption in office buildings, up to 45% of the total consumed. This energy consumption can be reduced by as much as 60% through an occupantdependent lighting control strategy. With particular focus on open-plan offices, where the application of this strategy is more challenging to apply due to differences in individual occupancy...

Lighting is an important factor in providing the appropriate learning environment at universities and educational facilities. It affects the learning outcomes and contributes to the aesthetic, psychological and health aspects of students, teachers and other users. Providing lighting is also costly and impacts on the environment. Thus, in choosing between competing lighting options an assessment...
