This paper explores three significant software development requirements for making the transition from standalone lighting simulation/analysis tools to simulation-based design aid tools. These requirements include specialized lighting simulation engines, facilitated methods for creating detailed simulatable building descriptions, and automated techniques for providing lighting design guidance. ...

Nowadays, the use of intelligent control systems to reduce human error is one of the most popularresearch fields. Design and implementation of such controllers requires to actual knowledge of theenvironment conditions. Traffic lights as one of the inputs of intelligent control systems are significant.usually the traffic lights have the various physical structure. also, generally in image proces...

This dissertation shows that computer-based lighting control systems can support the lighting design process considerably better than traditional consoles. It describes the Lula Project, a new software package for lighting design and control, that implements this level of support. Lula’s focus is on the conceptual ideas behind a lighting design rather than the concrete lighting fixtures used to...

Buildings are among the largest consumers of energy. Part of the energy is wasted due to the habits of users and equipment conditions. A solution to this problem is efficient energy usage. To this end, an energy audit can be conducted to assess the energy efficiency. This study aims to analyze the energy usage of a primary school and identify the potential energy reductions and cost savings. A ...

This paper describes the development of a new tool called hdrscope that enables users to perform qualitative and quantitative lighting analysis via perpixel methods. Using a simulated and photographically captured lab space as a case study, per-pixel analysis methods are described, challenges associated with per-pixel lighting analysis are discussed, and hdrscope analysis techniques are demonst...

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...

L IGHTING ACCOUNTS FOR ABOUT 15 PERCENT OF THE WORLD’S TOTAL ELECTRICITY CONSUMPTION, therefore a reduction of energy consumed for lighting will give a significant contribution to better utilization of the natural resources and a reduction of CO2 emissions. Recently, Light Emitting Diodes (LED) have been introduced in street lighting, building lighting, backlighting and automobiles lighting, ow...
