The Lighting context in France 2


Light & Energy consumption

in France

Only few regulations about lighting

thermal regulations, lighting has long been forgotten in

the regulations relatives to energy consumption

But the role of lighting in the energy consumption is

becomming more and more important

Therefore it is now taken into account in the Thermal

Regulation called RT 2012

Moreover, as a european country France must comply

with the european laws, and the EuP Directive which

ban inefficient light sources little by little


Lighting, a major energy consumer

Lighting contribute to 10% of France electricity consumption


in France

Street lighting 4 TWh 45%

Shops 9,5 TWh 20% to 80%

Offices 5 TWh 30%

Residential 9 TWh 11%

• A high potential of energy savings

30% to 50% of savings on the electricity bill (source

The quality of light

Law for workspaces, 1983

Every workspace has to have daylight

Minimum required illuminance (in lux) are specified by activity

But the levels required are not very demanding

Law for disabled people, 2007

Concerns every kind of public building (shops, train stations, museums, etc.)

Very demanding (illuminance levels, glare, etc.)

Lyon, « ville Lumière » 3
