LEED-AP-O+M Exam Dumps : LEED AP Operations + Maintenance (LEED AP O+M)

According to the LEED v4.1 Building Operations + Maintenance Guide, for a campus project using a Group Approach to comply with the Water Efficiency Prerequisite, Building-Level Water Metering, it is necessary to meter water use for all buildings aggregately with a single meter and also meter outdoor water use for the associated grounds1.

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 calculation used to achieve the Materials and Resources Credit, Purchasing - Ongoing, focuses on the cost of compliant furniture. This approach aligns with the intent of the credit, which is to encourage the purchase of sustainable and environmentally friendly products. By assessing the cost of compliant furniture, the credit incentivizes the selection of products that meet specific environmental criteria, thereby contributing to a more sustainable procurement practice.
