Good daylighting design in buildings not only provides a comfortable luminous environment, but also delivers energy savings and comfortable and healthy environments for building occupants. The importance of using daylight in educational buildings is because of the synchrony of operating hours of the school and daylight plenitude the sky. Daylight improves environmental quality and saves energy ...

The conclusions of a recent research project on the impacts of full-spectrum light on student performance and health prompted us to investigate the performance of students attending three daylit schools that were designed by our firm. The 1992 "Study into the Effects of Light on Children of Elementary School Age: A Case of Daylight Robbery" was conducted in Alberta, Canada by the Policy and Pla...

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 following Seesmart® Case Study contains portions from an original study article, “A comparison of traditional and high colour temperature lighting on the near acuity of elementary school children” (Lighting Res. Technol. 38,1 (2006) pp. 41_/52. Received 15 November 2004; revised 10 May 2005; accepted 10 May 2005). Photographs and charts were added to this Case Study by Seesmart® to illustra...

As LED lighting technology becomes omnipresent, lighting environments become more advanced and allow for adjusting various parameters such as color, brightness, and saturation. This poses challenges for interaction design, particularly when lighting environments are shared between multiple users. This paper presents “Vuur”: a shared physical interface with which users can control lighting in me...

This paper presents a design for intelligent control system of scene adaptive semiconductor lighting. The new design contains the host computer and the terminal in a control network. The lighting effect patterns are edited by the software on the host computer, then the lighting scene data is transported to the terminal through network. The terminal is a sub-controller based on the embedded syst...

This study was conducted to determine the effects of increasing lighting after peak production on eggs production and Hatchable Eggs in broiler breeder Hubbard F15. In this research we used from 4 growing saloons, that in per saloons were 5250 Hubbards broiler breeder hens. In this Experiment we used by Line design way of GLM for analysed data, that we considered the Effects of two parameters, ...

We present a framework for interactive lighting design based on linear re-rendering. The rendering operation is linear with respect to light sources, assuming a xed scene and camera geometry. This linearity means that a scene may be interactively re-rendered via linear combination of a set of basis images, each rendered under a particular basis light. We focus on choosing and designing a suitab...
