Assessment of Lighting Systems Based on the Normalized Power Density and Energy Losses Estimation in University Workrooms |
|
| چکیده انگلیسی مقاله |
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 were reduced . Furthermore, evaluating the lighting systems is very important to improving these systems. In this study the performance of the various lighting systems has been evaluated. In this study, comparisons between lighting systems have been performed and also energy losses were estimated. The lighting system conditions, energy loss and the difference between the lighting variables, based on room index and the designed required levels (normalized power density) in studied schools and education workrooms in Ahvaz Jundishapur University of Medical Sciences (south-west of Iran) have been evaluated. Results showed that the modern lighting systems had 58% more efficient than the traditional others. The performance indices of lighting systems between workrooms that had modern systems and traditional had significant (p = 0.000). In 77.4% of spaces of the school of Medicine, where that had new lighting systems, the satisfaction index of users were equal to one, and the loss of energy resulting from the operation of the lighting system is at the lowest possible level about -0.4 kWh/yr. m 2 . The consumption power of the school of Medicine was 63.7 KWh/yr.m 2 which is several times greater than the permissible limit. Evaluation of lighting systems in order to decreasing the electrical energy power along with preserving the standards of illumination intensity is very important, and some appropriate solutions could be adopted by replacing the traditional systems with the new others.
