Focus of modern lighting design

� The use of high-tech and sustainable materials

� The use of high output optical materials and reflectors

� The use of high tech light sources

� Well shaped design luminaires

� The lighting effects

-> these characteristics determine the budget for lightinginstallations

Nowadays sustainable lighting design is primarily based on:

Focus of modern lighting design

Which lighting design has the lowest energy demand?

B

• one luminaire - a halogen light bulb of 40 W

• a movement detector

• 10 times a day for 10 minutes

A

• one luminaire - an energy saving bulb of 11 W

• a central switch in the anteroom

• continuously for 10 hours a day

Both luminaires produce the same

amount of lumen

1. Introduction – 2. Refocus – 3. Energy saving – 4. LMS – 5. Projects – 6. Conclusion

A 110 Wh per day

B 67 Wh per day - 40% !

Costs versus benefits Savings Pay-back

� Stand-alone:

– Movement detection 30% 7-10 years

– Daylight dep. dimming 25% 7-12 years

� Light Management System50-70% 5-7 years

(more than 500 luminaires)

In some countries grants are provided by the government for those systems

-> shorter pay-back times
