Lighting at school should provide a high visual comfort by ensuring an adequate and appropriate illumination level and strictly preventing the risk of glare. Lighting system has to respect the legal standards especially safety standards for electrical equipment, and to enable the rational use of energy by promoting the highest energy efficiency.
When designing the lighting system for educational facilities, the designer has to pay attention to important criteria which affect the quality of the overall lighting solution:
– Colour temperature:
The colour temperature of a light source is a numerical measurement of its colour appearance. This temperature is expressed in Kelvin degrees. Colours and light sources from the violet/blue end of the spectrum are referred to as “cool,” and those toward the red/orange/yellow side are “warm”. Light colour may affect the mood, and learning behaviour. Cool light lamps will provide similar outdoor environment, which may help some students who can’t stand staying inside for hours, while warm colours lamps will provide a more relaxed, non-threatening learning environment. A colour temperature between 3000–4000K is generally recommended for classrooms
– Light quality:
The Colour Rendering Index (CRI) expresses the quality of light. The CRI is a scale from 0 to 100 percent indicating how truthfully the individual light sources are able to copy the colouring of the object compared to the natural daylight. The higher the CRI the more faithful the colour reproduction. Light sources with a colour rendering index above 85 are recommended for classrooms.
– Energy efficiency:
Energy-efficient lighting directly affects lighting costs. By selecting efficient lamps the number of fixtures required in a school can be reduced. To calculate the total lighting costs, you should consider beyond the purchase price the average maintenance costs (cleaning, lamp replacement).
Lighting can be an area for large gains in energy efficiency savings. The figures show that inefficient lighting systems in classrooms may represent 50 to 70% of electricity bills in many school facilities. Airfal offers efficient lighting solutions that help reduce energy costs while providing high quality illumination for students and teachers. Airfal lighting solutions for educational facilities (schools or universities) improve the feeling of well-being of the pupils and teachers, providing visual comfort and eye-protection that promote effective classroom teaching and learning in friendly and stimulating atmosphere.
