The Commissioning (Cx) Plan is a foundational document that outlines the scope and activities of the commissioning process. At a minimum, the plan should include an overview of the Cx program, which details the objectives and goals, the roles and responsibilities of the project team members involved in the commissioning process, and the sequence and timing of process activities. This ensures that all stakeholders understand the commissioning process and are aligned with its implementation.

References:

• The requirements for the contents of a Commissioning Plan are detailed in the Energy and Atmosphere Credit for Existing Building Commissioning under the LEED for Building Operations and Maintenance (O+M) reference guide. It is also highlighted in the LEED AP O+M training materials that a comprehensive Cx Plan is integral to documenting the systematic process of ensuring building systems perform interactively and efficiently.

The full value of the purchase can be claimed towards the credit because it meets the criteria for sustainable purchasing under LEED O+M v4.1. The produce is USDA Organic Certified and sourced from within 100 miles of the project, which qualifies for the local economy and environment category.

References: The LEED AP O+M Reference Guide provides detailed information on the requirements for the Materials and Resources Credit, Purchasing - Ongoing, including the emphasis on sustainable purchasing and supporting local economies12.

For the Materials and Resources Credit, Purchasing - Ongoing, the full value of $325.00 USD spent on USDA Organic Certified produce from a local farm (within 100 miles or 160 kilometers) can be claimed. This is because the LEED criteria for sustainable purchasing recognize and reward the procurement of local and organic food products to support sustainable agricultural practices and reduce transportation impacts. The entire amount spent on these products contributes towards the credit because it aligns with the goals of supporting local economies and reducing environmental impacts associated with long-distance food transportation.

References:The LEED AP Operations + Maintenance reference materials detail the criteria for sustainable purchasing, including the emphasis on local and organic food procurement. These guidelines specify how purchases like these contribute towards achieving the Materials and Resources Credit, Purchasing - Ongoing.

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.

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.

The Indoor Environmental Quality Credit for Integrated Pest Management within LEED criteria focuses on minimizing the exposure of building occupants and maintenance personnel to potentially hazardous chemical pesticides. This credit emphasizes the use of non-chemical pest management methods as the primary strategy and advocates for the least toxic chemical interventions as a last resort.

When an emergency situation necessitates the application of a pesticide that is not classified as the least toxic option, LEED guidelines require the project team to inform the building occupants in advance to ensure their safety and well-being. The stipulated advance notice period in such scenarios is 24 hours.

This 24-hour notice period serves multiple purposes:

• Occupant Preparation:It allows occupants to make necessary arrangements to minimize their exposure to the chemicals used, especially for those who might be particularly sensitive or vulnerable.
• Transparency:Providing advance notice upholds the principle of transparency in building management practices, reinforcing trust between the building management and the occupants.
• Safety Measures:It gives the facility management time to implement any additional safety measures or signage to prevent unintended exposure during and immediately after the pesticide application.
• Compliance and Documentation:Meeting this requirement is also crucial for LEED documentation and compliance, showcasing the project team's commitment to maintaining high indoor environmental quality standards.

References:The requirement for a 24-hour notice aligns with the LEED O+M: Existing Buildings v4 and v4.1 reference guide's emphasis on sustainable and occupant-friendly pest management practices. These practices are part of a broader approach to enhance the indoor environmental quality, ensuring that all building stakeholders are informed and protected from potential chemical exposure risks. This approach is detailed in the LEED O+M guide under the Indoor Environmental Quality category, where Integrated Pest Management strategies are discussed, emphasizing least toxic methods and occupant safety.

The correct answer is A because GreenPro, Ecowise, and Greenshield are service certifications that indicate the pest management services follow the principles of Integrated Pest Management (IPM), as stated in the web search results123.IPM is a comprehensive approach to pest management that minimizes the use of pesticides and maximizes the use of prevention, monitoring, and non-chemical methods4. The other options are incorrect because they either do not relate to pest management or do not follow the IPM principles.

Untreated stormwater, due to its potential contaminants, is not suitable for potable uses but can be effectively utilized for non-potable applications such as irrigation. It provides a viable alternative to using treated water for landscape irrigation, thereby conserving potable water resources. This use aligns with sustainable water management practices encouraged by LEED, which promote the reduction of potable water usage for landscape irrigation.

References:

• The LEED Reference Guide for Green Building Design and Construction and the LEED O+M Reference Guide both encourage the use of untreated stormwater for irrigation as part of an integrated water management approach. This conservation strategy is covered under the Water Efficiency category and is a common topic in LEED AP O+M training sessions.

This includes waste from commerce, trade, office buildings, institutions and small businesses. The other options are incorrect because they are either too high or too low compared to the actual data.

Commercial and institutional buildings are significant contributors to municipal waste generation. These buildings include offices, schools, retail stores, and healthcare facilities. Waste from these buildings comprises paper, cardboard, plastics, metals, glass, and organics, among other materials. The range of 35% to 45% accounts for the diverse activities within these buildings that generate waste, from daily operational waste to periodic large-scale waste from renovations and refurbishments. Waste management strategies in these buildings, such as recycling and composting programs, can significantly impact this percentage.References:LEED Reference Guide for Building Operations and Maintenance, U.S. Green Building Council.

The LEED for Existing Buildings: Operations & Maintenance (LEED EB: O&M) rating system includes a credit category called Materials and Resources (MR). Under this category, there is a credit called “Sustainable Purchasing – Ongoing Consumables” (MR Credit 1). This credit covers product purchases for the building and areas within the site manager’s control. One of the criteria for this credit is that food and beverages must be labeled USDA Organic1. Therefore, a USDA organic food product would qualify under this credit.
