Solar UV Measured under Built-Shade in Public Parks: Findings from a Randomized Trial in Denver and Melbourne
Suzanne Jane Dobbinson e outros, 2022 · International Journal of Environmental Research and Public Health
Installing purpose-built shade sails in public parks reduced solar UV radiation at the center of recreation areas by 3.47 SED per 30 minutes relative to unshaded controls.

3. Results > 3.2. UV Exposure at PRAs during 30 Min Potential Usage; Section 3.2 'UV Exposure at PRAs during 30 Min Potential Usage', paragraph 1
reduction in mean SED at shaded PRAs during posttest was statistically significantly lower than the other three experimental/test-period conditions (−3.47, 95% CI −4.65 to −2.30, P (z) < 0.001)
Contexto
What changed: High-UPF built shade structures were constructed over public park recreation areas. Comparison: Recreation areas randomly assigned to remain unshaded before and after intervention. Limits: UV levels under shade still approached 2 SED during peak midday summer hours, requiring supplementary protection for extended stays.
