Work life quality can be evaluated scientifically by considering into account all the factors effecting directly or indirectly the working of the humanly. For system approach, beside the method used during the work; work place planning, design of all the production tools and devices, physical and psycho-social environment are the factors effecting work satisfaction. Beside the physical factors ...

Despite the fact that there are currently a number of enjoyable digital games in which light plays a key role, we lack a vocabulary with which to discuss simulated illumination in game worlds. An understanding of lighting practices in other media, such as 3d computer-generated animation and film, must be supplemented with an awareness of real-space disciplines such as architectural lighting if ...

This paper presents a new method for calculating the design of roadway lighting. Apart from its accuracy, this method, which is based on a multi-objective evolutionary algorithm, has the added advantage of enhancing the energy efficiency of lighting installations. This is positive because the economic use of energy resources is evidently a priority in the world today. In our study, an exhaustiv...

Since the workshop held at the 23rd Session of the CIE in 1995, lighting quality has been established as one of the fundamental problems in lighting design, research, and education. The workshop at the 24th Session addressed a topic identified by delegates at the First CIE Symposium on Lighting Quality, held in 1998 [1]: the need to refine our definitions of luminous conditions to develop usefu...

This study aims to derive context-based lighting setup presets in residential space by exploring the multilateral relationships among household activities, affects, and lighting setups. Three procedures were involved: First, sixty affective words were evaluated through which seven affect factors were extracted to facilitate the evaluation of colored illumination in the subsequent experiment. Se...

A number of villages in India is yet to be electrified due to its location. At the same time it is also important to mention that grid connection to those areas is very expensive and time consuming. The source of lighting in those areas are conventional fuel based lighting system i.e. mainly kerosene based lantern. It has immense health hazard and environmental impact. To meet the energy demand...

This report presents a framework for per-pixel analysis of the qualitative and quantitative aspects of luminous environments. Recognizing the need for better lighting analysis capabilities and appreciating the new measurement abilities developed within the LBNL Lighting Measurement and Simulation Toolbox, “Per-pixel Lighting Data Analysis” project demonstrates several techniques for analyzing l...

Day lighting is one of the important qualitative factors in housing, which is also effective on health and well-being of occupants. Extensive glass surfaces and Transparency in building facades provides good daylight quantity for interior spaces. However, this lighting system is not appropriate for climates faced with higher sunlight radiation (Such as hot-humid areas), due to overheating and d...
