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

This answer is correct because it follows the guidance provided by the LEED v4.1 O+M Reference Guide for dealing with nonparticipating tenants in multi-tenant buildings. The guide states that if a tenant is unwilling or unable to provide their purchasing data, the project team must integrate the estimated data from the nonparticipating tenant into the whole-building purchasing data to determine compliance for the whole building.The guide also states that the tenant’s purchasing is assumed to be 50% compliant toward the sustainability criteria, unless the project team has a more accurate estimate1. The other options are incorrect because they either make the credit impossible or too easy to achieve, or they do not account for the tenant’s purchasing at all.

Recommending LED lamps in an environmentally preferable purchasing policy is beneficial because LED lamps contain no mercury. Unlike some other lighting options, such as compact fluorescent lamps (CFLs) which can contain mercury, LEDs offer a safer alternative in terms of toxic substances. This makes LED lamps an environmentally friendly choice, reducing the risk of mercury pollution and facilitating easier, safer disposal or recycling of lamps at the end of their life cycle.

References:The LEED AP Operations + Maintenance documentation highlights the environmental and health benefits of selecting LED lighting, including the absence of mercury, which aligns with the goals of reducing hazardous substances in building environments.

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.
