LEED AP Building Design and Construction (BD+C) Practice Exam

What is the minimum percentage of parking spaces that must be placed under cover for Heat Island Reduction Option 2?

1. 50%

2. 60%

3. 75%

4. 90%

The correct answer is: 75%

For Heat Island Reduction Option 2, the requirement is that a minimum of 75% of parking spaces must be placed under cover to help mitigate the urban heat island effect. This approach emphasizes the importance of reducing heat absorption and enhancing the overall thermal performance of the site. By providing substantial coverage over the parking areas, the surfaces are less exposed to direct sunlight, which can significantly decrease heat generation and improve the thermal comfort for both the vehicle occupants and the surrounding environment. By positioning the parking spaces under cover, whether through the use of structures like carports or building overhangs, there will be a reduction in heat absorption from dark pavement surfaces, ultimately contributing to lower ambient temperatures and cooler microclimates in the vicinity. This strategy not only addresses heat island mitigation but also improves energy efficiency for buildings and enhances user experience through cooler parking areas during hot weather. The other percentages provided do not meet the criterion set by this option and do not fulfill the LEED standards for optimal heat island reduction efforts as required in this context.
