Changed LEED-AP-O+M Exam Questions

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.

To increase the vegetated area of an existing urban site from 4% to equal or be greater than 5%, one effective strategy is to install a vegetated roof system. This approach not only increases the site's vegetated footprint but also provides additional benefits such as improved stormwater management, increased insulation, and reduction of the urban heat island effect. A vegetated roof system can be implemented on flat or slightly sloped roofs, making it a versatile option for urban environments where ground space may be limited. By converting unused roof space into green space, the project team can meet the goal of increasing the total vegetated area of the site.References:LEED Reference Guide for Green Building Design and Construction, U.S. Green Building Council.

Outlet powered task lighting under the Indoor Environmental Quality Credit, Interior Lighting, contributes towards compliance for individual occupant spaces. This is because task lighting allows individual occupants to control their own lighting levels, which can improve comfort and productivity.

When calculating the Water Efficiency Credit for Outdoor Water Use Reduction, the irrigation of athletic fields may be included or excluded based on the project's specific circumstances and goals. This flexibility allows projects to tailor their water efficiency strategies to their unique site conditions, uses, and priorities, ensuring that the approach to outdoor water use reduction is both practical and effective.References:The Water Efficiency section of the LEED O+M Reference Guide provides guidance on calculating outdoor water use, offering options for including or excluding certain areas like athletic fields to meet the project's needs.
