CRITICAL DESIGN ISSUES:
Daylighting Integration and Control: The introduction of daylight into lounge
areas can help to make it a more relaxing and inviting space. Use daylight
controls to turn off unnecessary electric lighting.
Appearance of Space and Luminaires: Select luminaires to enhance the
appearance of the room and accent features of the space. Luminaire layout
should avoid visual clutter of the space.
Luminance of Room Surfaces: The room will feel bright if surfaces are
illuminated. A recessed direct / indirect luminaire puts some light on the
ceiling if the shielded "basket" drops below the ceiling plane. The use of
downlight wallwashers highlights artwork or just adds to the overall
brightness of the space.
Color Appearance (and Color Contrast): The color of accent walls,
architectural features, and artwork needs to be rendered accurately.
