ABSTRACT: This paper reports a study which calculated shade effect against UV radiation using a UV
Shade Chart. Ultraviolet radiation damages the skin. The use of sun-shading is an effective means of
blocking this radiation. Membrane structures are sometimes used as sun-shades – however, it is
difficult for a membrane structure to be evaluated for a shade effect against ultraviolet radiation
because of its free shape. The UV Shade Chart which has been developed expresses sky erythema
radiance as point density. The Chart has been used to evaluate several kinds of shades by calculating
the architectural sun protection factor (ASPF).
