The document provides an overview of strategies for reducing excess lighting consumption in workplaces, highlighting both technical and behavioral causes of inefficiency. It discusses the importance of modernization, lamp replacement, lighting control systems, and the integration of natural light into workplace design, with potential savings of up to 80% in certain cases. Additionally, it outlines specific measures that can be taken to improve energy efficiency, such as rearranging workplaces, improving employee behaviors, and adopting energy-efficient lighting technologies.

4. Reasons for excess
consumption
 Excess consumption through technical issues:
– Reduced area for natural lighting
– Use of outdated and low efficiency lamp
technology
– Use of ferromagnetic ballasts
– Inexistent reflectors on fixtures
– Over lightened areas
– Use of general instead of located lighting
 Excess consumption through behavioral issues:
– Dirty reflectors on fixtures
– Lighting turned on unnecessarily

6. Political aspects
 Since September 2009, non-clear (frosted)
lamps have to be of A-class standard
according to the EU's lamp energy label.
 Conventional incandescent and halogen
bulbs which cannot meet these
requirements were gradually phased out
from the EU market till late 2012.
 Only compact fluorescent lamps and LED
lamps can achieve the A-class standard - all
the more inefficient non-clear types will
disappear.

 Project: Optimisation of lighting in an
underground parking for buses
 Problem:
–
–
–
–
65 conventional neon lightings were used
Inadequate illumination,
24 hours operation over 365 days,
High energy consumption, waste of lamps
 Measures:
– Replacement of the lamps with 116 more
efficient and better positioned neon lightings
– Conventional ballasts were replaced with
electronic ballasts, which have lower power
dissipation results (10-20 percent less) and allow
computerised dimming

Excess energy consumption through lighting is
caused by technichal as well as behavioural issues.
Through the modernisation of the production sectors
and storage areas savings of up to 80 % are possible.
Lamp replacement can effect up to 40 % energy
saving.
Efficient lights through installation of mirrored
reflectors
Through the selection of bright wall colors, the
adaption of the light arrangement and the
installation of cable conduits, pipelines, plant
components and high-bay racks the room utilisation
factor can raise.
