Lighting accounts for a significant amount of electrical energy consumption in office buildings, up to 45% of the total consumed. This energy consumption can be reduced by as much as 60% through an occupantdependent lighting control strategy. With particular focus on open-plan offices, where the application of this strategy is more challenging to apply due to differences in individual occupancy...

The COPE (cost-effective open plan environments) project investigates the effect of open-plan office design on the indoor environment and on the occupant satisfaction with that environment. COPE is sponsored by a consortium of North American public and privatesector organizations and relies on field, laboratory and simulation studies to address design aspects like acoustics, lighting quality, i...

well-designed lighting decreases accidents and diseases of eyes and can increase productivity and concentration. increase of energy price and a high proportion of electric lighting energy consumption in buildings due to defects in designing and maintenance led to desirable lighting to be reduced. one of our challenges in providing health and quality of lighting is lack of economic justification...

In a distribution ray tracer, the crucial part of the direct lighting calculation is the sampling strategy for shadow ray testing. Monte Carlo integration with importance sampling is used to carry out this calculation. Importance sampling involves the design of integrand-speci c probability density functions which are used to generate sample points for the numerical quadrature. Probability dens...

Detecting moving pedestrians and vehicles with foreground segmentation algorithms is problematic during fluctuating lighting conditions. Edge-based approaches are more robust to lighting than the conventional intensity-based ones. The issue with edge-based approaches though is segmenting the internal foreground areas. In this work a strategy is developed to detect complete foreground areas. Fir...
