Outline of Final Research Achievements

We have studied the solar retroreflectors, as the urban heat island countermeasure. In this study, to fabricate a Gonioradiometer which can measure the BRDF facet average amount of reflection and wide angle range. Also, to verify the accuracy of the instruments and measure the BRDF of retroreflector. Measurement of the BRDF show peak in retro-reflect direction and BRDF is decreased as it goes away from there. Measurement of the BRDF is general retroreflective distribution which measured.
