An inclusive peer-to-peer approach to involve EU CONURBations and wide areas in participating to the CovenANT of Mayors 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
Public lighting Exsisting condition Energy consumption for each section Collection of number and typologies of lamps National standard and regulation about street lighting
Public lighting Energy - Economical Balance 1- Energy costs: due to energy consumption • Depending on lamp technology and hours of operation 2 – Fixed costs: due to maintenance, substitution, etc.
Public lighting Example of fixed costs SVL : sodium vapour lamps, MVL: Mercury Vapor Lamps, ISL: incandescent Lamps
Public lighting Example of energy costs Day/year : 365, elect price= 0.18 €/kWh
Public lighting Example of energy gain
Public lighting How to plan refurbishment? • Howlighting: directcontrolof the luminousflux • Howlighting: indirectcontrolof the luminousflux • Whattouse - higlyefficient light sources • Optimisationoflighting • Light Management
Directcontrolofluminuousflux 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 "
Indirectcontrolofluminuousflux The average maintained luminance of the surfaces to be illuminated should not exceed the minimum standards set by the technical rules of safety
Whattouse - higlyefficient light sources 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.
Optimisationoflighting • Classify roads according to the provisions of law • Employment, at the same luminance and illuminance, of appliances that deliver, with reduced by electrical power, optimum conditions for wheelbase points of light and reduced maintenance costs.
Lighting management 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
Be careful with energy saving because… First of all … lighting quality!!! And respect of the law ….
