Eunice Noell-Waggoner, IES, LC. Value, Contrast and Reflections

(Note: A transcript of this presentation was not available. These edited Proceedings are based on notes by JEW and TOS, and slides that accompanied the presentation)

Exterior Considerations (slides 2 and 3)

Contrast is needed at ramps & curbs to alert for trip hazards. A negative example is shown in slide 2, left photo.

Steps or raised areas should be defined with value contrast. A negative example is shown in slide 2, right photo.

Edges should be defined by added contrast. A negative example is shown in slide 3, left photo; a positive example is shown in slide 3, right photo.

Reflective & Transparent Surfaces can be Dangerous

Vertical Surfaces (slide 4)

Two examples are shown of hazards from reflective and transparent vertical surfaces.

Polished Horizontal Surfaces (slide 5)

Disability Glare can distort pathways.

Reflected glare can result from windows, skylights and electric down lights.

Stairs can be Dangerous (slide 6)

Main stairs and emergency egress stairs must be highlighted. In slide 6, a negative example is shown in the left photo for the emergency egress stairway; a positive example is shown in the right photo for a main stairway.
