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

The correct answer is A because mulching is an environmentally friendly technology for controlling erosion, as stated in the web search results12. Mulching involves applying organic or inorganic materials on the soil surface to protect it from water and wind erosion.Mulching can also conserve soil moisture, moderate soil temperature, and enhance soil fertility2. The other options are incorrect because they either do not control erosion effectively or cause environmental harm.

Mulching is an environmentally friendly technique used to control erosion by providing a protective layer on the soil surface. This layer helps to reduce the impact of raindrops on the soil, thereby decreasing the potential for soil erosion. Mulch can be made from a variety of organic materials, such as shredded bark, straw, or compost, which not only protect the soil from erosion but also add nutrients as they decompose, improve soil structure, and encourage healthy plant growth. Unlike impermeable solutions like asphalt or temporary solutions like tarpaulin, mulching integrates with the natural environment and supports sustainable land management practices.

When a building is recertified in LEED Operations and Maintenance, it should use the LEED version that is current at the time of registration for recertification. This approach ensures that the building is being assessed under the most recent standards and requirements, reflecting the latest advancements and best practices in green building.References:LEED Operations and Maintenance Reference Guide, Introduction and Overview section.

When a building initially certified under LEED EB v2.0 seeks recertification, the appropriate version to use is the one that is current at the time of registration for recertification. LEED rating systems go through updates and revisions, and at any given point, they can be either open for registration and certification, closed for registration but open for certification, or completely closed for both registration and certification (sunset). The deadlines for these phases are published by the USGBC. Therefore, a building pursuing recertification must align with the most current version available at the time of its registration for recertification.

For a building that shares chilled water usage with other buildings on a campus, if the chilled water consumption is only measured at the campus level, additional meters would be required to comply with the Energy and Atmosphere Prerequisite for Building-Level Energy Metering. Individual metering at the building level is necessary to accurately track and manage the building's specific energy consumption, enabling targeted energy efficiency measures and compliance with LEED requirements.References:The Energy and Atmosphere section of the LEED O+M Reference Guide outlines the requirements for building-level energy metering, including the need for individual metering of significant energy uses such as chilled water in shared systems.
