The overall scope of this project funded by the US Department of Energy (DOE) is to recommend means of reducing barriers to the wide spread use of lighting controls for commercial/industrial (C/I) applications using fluorescent systems. It is important to note that this project is focused on load-shed applications and photoelectric dimming where energy savings and energy management are of centr...

This study presents a contribution to the characterization of occupants’ behavior regarding the manual control of electric lighting in combination with shading control in offices. The procedure and monitoring results for eight single-occupied office spaces is described. The analysis of the collected data indicated that occupants kept electric lighting On during most of the monitoring period and...

this study was conducted to compare the effects of different illumination programs on the cellular and humoral immune system using 320 one day–old male broilers (arian 386) in a completely randomized design of 8 replications (10 birds each). the four assayed lighting schedules were comprised of: 1- continuous lighting (control), 2- decrease then sudden increase of lighting, 3- decreasing-gradua...

We present a new technique which enables direct volume rendering based on 3D texture mapping hardware, enabling shading as well as classification of the interpolated data. Our technique supports accurate lighting for a one directional light source, semi-transparent classification, and correct blending. To circumvent the limitations of one general classification, we introduce multiple classifica...

Architects often use two-dimensional media to represent, visualise, and study the three-dimensional qualities of un-built spaces. Knowledge of pictorial cues is a powerful design tool that can be used to enhance the spatial qualities of built environments. This paper draws from the recent developments in computer graphics (physically based renderings and perceptually based tone mapping techniqu...

Visual comfort in indoor spaces depends on the amount and quality of light available and also on space characteristics. One of the most influential aspects is the colour of surfaces defining a space. Each colour has a reflectance coefficient resulting from how much light is reflected back from the coloured surface. However, from the observer’s point of view, there are other factors that may aff...

Within the scope of working areas in residential spaces, home-office method, which is becoming more common as a flexible style, has been examined The relationship between circadian lighting reinforcement system and human biology places from home investigated. In terms interior design setup offices, approaches are taken into consideration, their spatial solutions evaluated point efficiency, conc...
