USGBC LEED-AP-O+M Exam With Confidence Using Practice Dumps

This answer is correct because these are the two factors that affect the heat island reduction potential of the materials. The SRI is a measure of how well a material reflects solar radiation and stays cool in the sun. The higher the SRI, the lower the surface temperature and the less heat absorbed by the material. The unbound percentage of the open-grid pavement system is the ratio of the area that is not covered by the paving material to the total area of the system. The higher the unbound percentage, the more permeable the system and the more water infiltration and evaporation, which also reduce the surface temperature. The vegetated roof system does not need to have a specific SRI value, as long as it uses native or adapted plant species that provide shade and evapotranspiration. The open-grid pavement system does not need to have a specific SRI value, as long as it has at least 50% unbound area.

The Location and Transportation Credit, Alternative Transportation: Option 1. Transportation Survey, is primarily concerned with understanding and improving the commuting patterns of the people who work at the facility on a regular basis. In the case of an in-patient hospital project, this would be the hospital employees. The goal is to reduce the environmental impact of commuting by encouraging alternative transportation methods such as public transit, carpooling, biking, or walking.

The LEED AP Operations + Maintenance (LEED AP O+M) V4.1 focuses on improving the sustainability of existing buildings that are fully operational and have been occupied for at least a year12. Administering an alternative transportation survey is appropriate when the daily average or typical peak number of visitors is at least 50% of the regular building occupants. This is because the survey aims to understand and improve the transportation habits of a significant portion of the people interacting with the building, which includes both regular occupants and visitors. By focusing on this group, the LEED AP can identify opportunities to encourage alternative transportation modes, thereby reducing the building’s overall environmental impact.
