The requirement regarding the solar reflectance index (SRI) for roofs used to shade covered parking is focused on minimizing the heat island effect, which is critical for sustainable building practices. An aged SRI of at least 0.32 is necessary to ensure that the roofing material reflects a sufficient amount of solar radiation and contributes to a cooler environment, particularly in urban areas that can experience higher temperatures due to heat absorption by buildings and pavements.

Higher SRI values indicate better reflective properties, which reduces heat buildup on surfaces, helps lower energy demand for air conditioning, and ultimately improves overall urban microclimates. This standard not only aligns with LEED's goals for energy efficiency and sustainability but also enhances occupant comfort and reduces the urban heat island effect in densely populated areas.

Meeting this minimum SRI requirement is critical for projects aiming for certification under the LEED program, making the selection of materials that can achieve at least this level a necessary consideration in design and construction phases.
