Dynamic analysis of office lighting smart controls management based on user requirements

Lighting programme and iranian schools lighting requirements

It is accepted that the visual comfort in schools depends on the quality of the whole visual environment. This leads to the concern upon the quality and quantity of lighting. Currently in Iran, in order to calculate energy transfer for public buildings a coefficient is usually used. This coefficient considers the rate of sunlight energy absorption in these kinds of buildings. To increase the ...

Intelligent Office Lighting: Demand-Responsive Conditioning and Increased User Satisfaction

A New Key Management Scheme Based on Smart Grid Requirements

Smart grid (SG) comprises a set of technologies that uses sensing, embedded processing and digital communications to intelligently control and monitor an electricity grid with improved reliability, security, and efficiency. However, its reliance on traditional IT principles presents a new attack vector for security threats and vulnerabilities. Key management is a fundamental requirement for sec...

Experiential Lighting: Development and Validation of Perception-based Lighting Controls

Lighting, and its emergence as a digital and networked medium, represents an ideal platform for conducting research on both sensor and human-derived methods of control. Notably, solid-state lighting makes possible the control of the intensity, spatial, and color attributes of lighting in real-time. This technology provides an excellent opportunity to conduct new experiments designed to study ho...
