The inherent control flexibility implied by solid-state lighting – united with the rich details offered by sensor networks – prompts us to rethink lighting control. In this research, we propose several techniques for measuring work surface illuminance and ambient light using a sensor network. The primary goal of this research is to measure work surface illuminance without distraction to the use...

aims: work proper lighting means a safe, healthy and comfort conditions for work under a lighting system that includes qualitative and quantitative features. this study aimed to evaluate the surface local lighting of works and eye fatigue among research and development staffs of an automotive industry. instrument & methods: in this descriptive study in research and development department of an ...

background: the aims of this study were to evaluate the employees' subjective assessments of different aspects of lighting condition as well as task area illuminance in manufacturing plants. methods: this field study was conducted between march and may 2013 , in three packing plants (saveh, central iran). data were collected by questionnaire and measurement of the task area illuminance levels. ...

In this paper, a new optical approach based on omnidirectional thermal visualization system is proposed. It will provides observer or image processing tool a 360 degree viewing of surrounding area using a single thermal camera. By applying the proposed omnidirectional thermal visualization system even in poor lighting condition, surrounding area is under proper surveillance and the surrounding ...

Improved detection of thermal insulation efficiency in buildings could substantially contribute to reductions in energy consumption and the carbon footprint of domestic heating systems. Thermal insulation standards are now contractual obligations at the construction stage, although they are not standardized in buildings that are already in operation: lighting, occupancy and temperature profiles...

The present work proposes a simulation and control framework for home building automation, focusing on heating, ventilating, air conditioning processes. Control systems based different advanced architectures policies are simulated compared, highlighting performances, energy-saving results in terms of CO2 emissions reduction. Heat, lighting, natural ventilation phenomena were modelized through f...
