What is one of the requirements for roofs used in shading covered parking?

Using a vegetated roof for covered parking provides a variety of benefits that align with sustainable design principles. Vegetated roofs are effective in reducing the urban heat island effect by decreasing the amount of heat absorbed and reflected by traditional roofing materials. This can lead to lower temperatures in surrounding areas, helping to minimize energy consumption for cooling buildings and creating more comfortable outdoor spaces.

Additionally, vegetated roofs enhance stormwater management by absorbing rainwater, which reduces runoff and can mitigate local flooding. The presence of vegetation also promotes biodiversity by providing habitats for various species. Moreover, these roofs contribute positively to the aesthetic appeal of a parking structure and can improve air quality.

While other options may have certain benefits, a vegetated roof specifically supports multiple sustainability goals outlined in the LEED certification process, making it a strong choice for covered parking.
