Minimizing energy usage and increasing occupant comfort are the two primary objectives of intelligent and eco-friendly buildings. Energy savings of up to 70%, combined with significant occupant productivity gains are possible via the application of wireless sensor and actuator networks (WSAN). Despite the increasing interests in WSAN-based wireless intelligent lighting control, no prior survey ...

Lighting design is an important topic of 3D scene design. There are many functions that lighting assumes in game environments, including directing attention, visibility, evoking emotions, setting atmosphere, and providing depth. Due to the unpredictability of interactive environments, current lighting design models do not adequately adapt the lighting to serve these aesthetic and communicative ...

With the development of modern technology and Android Smartphone, Smart Living is gradually changing people’s life. Bluetooth technology, which aims to exchange data wirelessly in a short distance using short-wavelength radio transmissions, is providing a necessary technology to create convenience, intelligence and controllability. In this paper, a new Smart Living system called home lighting c...

Control system development and lighting energy monitoring of ceramic thin-film electrochromic (EC) windows were initiated at the new full-scale Window Systems testbed facility at the Lawrence Berkeley National Laboratory (LBNL) in Berkeley, California. The new facility consists of three identically configured side-by-side private offices with large-area windows that face due south. In one room,...

Intelligent lighting systems employ dimmable luminaires, photosensors, and occupancy sensors to adapt to daylight and user presence conditions in indoor environments. By providing the illumination required for users and no more, significant energy savings can be made. The state of the art in these lighting systems currently relies on dedicated communication hardware such as radio networking mod...

The localization of people and objects in different environments is an essential prerequisite for many applications in navigation, robotics, machine control and monitoring. The limiting factor for many applications is the indoor environment in which the Global Satellite Systems work only partially or cannot function at all. Currently radio frequency (RF) based methods are being increasingly imp...

As issues of environment and energy draw keen interest around the globe due to such problems as global warming and the energy crisis, LED with high optical efficiency is brought to the fore as the next generation lighting. In addition, as the national income level gets higher and life expectancy is extended, interest in the enhancement of life quality is increasing. Accordingly, the trend of li...
