slide1

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

slide3

Public lighting

Exsisting condition

Energy consumption for each section

Collection of number and typologies of lamps

National standard and regulation about street lighting

slide4

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.

slide5

Public lighting

Example of fixed costs

SVL : sodium vapour lamps, MVL: Mercury Vapor Lamps, ISL: incandescent Lamps

slide6

Public lighting

Example of energy costs

Day/year : 365, elect price= 0.18 €/kWh

slide7

Public lighting

Example of energy gain

slide8

Public lighting

How to plan refurbishment?

  • Howlighting: directcontrolof the luminousflux
  • Howlighting: indirectcontrolof the luminousflux
  • Whattouse - higlyefficient light sources
  • Optimisationoflighting
  • Light Management
slide9

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 "

slide10

Indirectcontrolofluminuousflux

The average maintained luminance of the surfaces to be illuminated should not exceed the minimum standards set by the technical rules of safety

slide11

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.

slide12

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.
slide13

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

slide14

Be careful with energy saving because…

First of all … lighting quality!!!

And respect of the law ….
