How to obtain specific data for lamps and buildings or related to RES plants feasibility and how to organize information to support decisions related to interventions and investment
Energy consumption for each section
Collection of number and typologies of lamps
National standard and regulation about street lighting
Energy - Economical Balance
1- Energy costs: due to energy consumption
2 – Fixed costs: due to maintenance, substitution, etc.
Example of fixed costs
SVL : sodium vapour lamps, MVL: Mercury Vapor Lamps, ISL: incandescent Lamps
Example of energy costs
Day/year : 365, elect price= 0.18 €/kWh
Example of energy gain
How to plan refurbishment?
Use equipment which, in their installed position, must have a maximum range of the light intensity distribution of> 90 °, between 0.00 and 0.49 candelas per 1000 lumens of total luminous flux emitted.
Typically, the lamps and the possible protective transparent should be 'embedded in the top of the same optical "
The average maintained luminance of the surfaces to be illuminated should not exceed the minimum standards set by the technical rules of safety
Using advanced technology, lamps and lighting efficiency, such as high pressure sodium or low pressure, rather than those with lower light output, depending on the type of application and the best result in terms of limiting the powers of single and installed ' entire system. And 'The use of lamps with color rendering index greater than Ra = 65, and efficiency, however, is not less than 89 lm / w, only the lighting of monuments, buildings, areas and city centers aggregate in areas of proven value cultural and / or social to pedestrian use.
Lighting installations must be equipped with special devices that act promptly on each lamp or the entire system in general, able to reduce and control the light flow in excess of 30% compared to the nominal rate, without compromise safety
First of all … lighting quality!!!
And respect of the law ….
