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.

The Energy and Atmosphere Credit for Existing Building Commissioning - Implementation requires a master list of findings. This list is essential to document the current performance of building systems and to identify opportunities for improvement.

References: The LEED v4.1 O+M reference guide includes the need for a master list of findings as part of the commissioning process to ensure that all systems are performing to the expected standards and to help prioritize actions for energy efficiency1.

For compliance with the Energy and Atmosphere Credit, Existing Building Commissioning-Implementation, one of the key requirements is to develop a master list of findings from the retro-commissioning process. This list should include all identified issues that need to be addressed and rectified. It serves as a comprehensive overview of the building's systems and equipment's performance, aiding in the identification and prioritization of corrective actions.

For the Indoor Environmental Quality Credit, Thermal Comfort, the system must continuously monitor both humidity and air temperature. These two factors are crucial for maintaining thermal comfort within the building environment.

References: The LEED v4.1 O+M reference materials specify the importance of monitoring humidity and air temperature as part of the requirements for achieving the Thermal Comfort credit12.

To achieve the Indoor Environmental Quality Credit, Thermal Comfort, the system must continuously monitor at least two key factors: humidity and air temperature. These factors are critical for maintaining thermal comfort within a building, as they directly affect the perceived comfort levels of the occupants. Proper monitoring and management of humidity and air temperature ensure that the indoor environment remains within comfortable ranges for occupants, contributing to their well-being and productivity.

References:This requirement is specified in the LEED AP Operations + Maintenance reference guide within the section on Indoor Environmental Quality Credit, Thermal Comfort. The guide emphasizes the importance of maintaining optimal levels of humidity and air temperature for achieving thermal comfort in indoor spaces.

The correct answer is A because a table of lighting controls installed is the required documentation for Option 1.Lighting Controls in Indoor Environmental Quality Credit, Interior Lighting, as stated in the LEED v4.1 O+M Reference Guide1.The table must include the type and location of each lighting control device, the controlled lighting power, and the percentage of lighting power controlled by each device1. The other options are incorrect because they are either not required or relevant for this option.
