CRITICAL DESIGN ISSUES:
Appearance of Space and Luminaires: Because building visitors often meet
in conference rooms, the aesthetic character of the luminaires is an
important consideration.
Direct Glare: Lamps in the luminaires are shielded with louvers,
perforations, or lenses to avoid a direct view of the lamps and the resultant
glare.
Light Distribution on Surfaces: Illuminate the room surfaces uniformly,
especially the ceiling and walls. Patterns of light or shadows on surfaces
can be distracting and confusing.
Light Distribution on Task Plane: The lighting system should provide a
uniform distribution of light on the conference table with minimal shadowing.
This will provide a comfortable environment for writing tasks without
causing fatigue or eyestrain.
