General illumination using LEDs has enabled designers to have precise control of the intensity and color of an illuminated area. In this work, I investigate how these systems can dynamically adjust to create optimal lighting conditions in the built environment. By incorporating environmental feedback into a system control loop, i.e., illuminance or luminance measurements, the precise intensity ...

By the rise of concerns for global warming, reducing emissions via lowering energy consumption has become a necessity in every sector and the lighting sector is no exception. However, it should not come at the cost of lighting quality and user comfort which is a common practice in today’s lighting design and energy reduction initiatives. The “energy reduction” view should change toward “value d...

The healthcare sector of today has very precise requirement with regard to interior lighting. To fulfill these needs, international standards which specify the strict requirement for each health care facility have come up. Hospital lighting is in particular complex because of the sensitive nature of various patients as well as requirement of high performance from its employees. Hence this makes...

This paper gives an overview of image-based representations commonly used for reducing the geometric complexity of a scene description in order to accelerate the rendering process. Several different types of representations and ways for using them have been presented, which are classified and discussed here. Furthermore, the overview includes techniques for accelerating the rendering of static ...

The purpose of this study is to examine the effect visual merchandising store image and purchase intention through importance factors such as front entrance product display, displays, layout organization, theme, signage/graphic, lighting sound usage. This also looked at effects on intention. Ikea Alam Sutera Indonesia used a research object because in store, elements are designed detail create ...

Research suggests that specialized lighting design is essential to cater for the elderly users of a building because of the physiological changes in the eye with increased age. Recent studies have established that lighting in a space impacts on users’ physical performance as well as on the mental state. In particular, light therapies have been found to be successful in treating several mood dis...

Lighting influences users' visual strain and well-being. Therefore creating lighting that ensures visual work conditions do not result in visual fatigue is a preventive activity. The aim of the study was to model different lighting systems for visual display terminal (VDT) work and to determine their influence on users' visual strain and preferences. The results of the study showed that visual ...
