Lighting requirements
• equal visual conditions in every seat
• variable light intensity (500 – 1000 lx)
• board lighting with high uniformity
• good facial recognition
• raised cylindrical illuminance levels and good modelling
• good glare control (UGR ≤ 16/19)
• optional: dynamic light (TW D/I for HCL planning
concepts) and pre-programmed lighting scenes
• optional: highly efficient luminaires with daylight/presence
sensor technology for low energy consumption
We are on-site for you – simulated in this case. You will
find a selection of different simulations of a classroom
with common structural conditions on the following pages.
They are based on a 72 m2 lecture hall for 24 learners, with
a blackboard, and a table for the lecturer(s).
Concrete and plasterboard ceilings or grid ceilings are
simulated in combination with various mounting variants
from several luminaire series: recessed, surface-mounted,
and suspended.

* Modelling factor: The modelling describes the relationship between cylindrical
and horizontal illuminance Eh at one point and should be in an interval between
0.30 and 0.60.
