Energy Saving Lighting Systems
Helvar Lighting Controls B.V. Leerdam
have an outlet of 2.5 Million ton CO² without cause?
do we consume approximately 5.9 TWh of electrical energy without cause?
More than 250.000 commercial flights between Stockholm and Copenhagen
The same amount as one nuclear power plant are producing during 1 year
About the same as the annual outlet from 800 000 cars
WHY…
A good lunch meal instead of an expensive bill for energy
New lighting with the latest technology in Swedish schools would
save 37 Million Euros annual
This potential saving

20-30% Is used in private owned commercial buildings and in public buildings
90 % Of the effect on the Environment comes from energy usage
10 % are from Manufacturing, Transport and Recycling
70 % is cost for energy
Short pay back time
Lighting energy
By lowering the light level from 100% - 20% the energy usage will be lowered by ~80%
Linerar saving down to 20%
Ullevål Hospital, Norway
300,000m2 , 8 100 employees 113 GWh Energy consumption The cost for energy was lowered by 82%
for the Lighting All this with modern advanced optics
in the luminaries and with Helvar ballasts and Helvar Ligting Systems
With maintained or improved lighting quality

How you could get affected by poor lighting
Dålig belysning kan leda till trötthet och huvudvärk. Lagom starkt, bländfritt ljus kan göra det lättare att arbeta.
Faulty working position
Problems with the neck or shoulders
