USGBC Updated LEED-AP-O+M Exam Questions and Answers by zuzanna

To achieve exemplary performance in the Materials and Resources Credit, Solid Waste Management - Ongoing, a diversion percentage of 90% for ongoing consumables is required. This high level of diversion demonstrates an advanced commitment to reducing waste and promoting recycling and composting. By diverting 90% of ongoing consumables from the landfill, projects significantly contribute to sustainability goals by minimizing their environmental footprint related to waste.

References:The LEED AP Operations + Maintenance reference guide specifies the criteria for exemplary performance in waste management, including the 90% diversion target. This ambitious goal underscores the importance of comprehensive waste reduction strategies in LEED-certified projects.

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.

References: LEED v4: Building Operations + Maintenance Guide1, LEED certification for existing buildings and spaces2.

This is the correct answer because LEED v4.1 O+M requires projects to provide storage locations for at least five of the following recyclable materials: mixed paper, corrugated cardboard, glass, plastics, metals, batteries, mercury-containing lamps, and electronic waste. Option D lists five of these materials, while the other options include materials that are not required by LEED, such as paint, wood pallets, or electronics.

Increasing the treatment levels of potable makeup water is an allowable method to increase cooling tower cycles of concentration. This is because treating the makeup water can help control the buildup of minerals and other impurities, allowing the system to operate more cycles before requiring blowdown.

References: The LEED v4.1 O+M reference guide and other LEED resources emphasize the importance of water treatment to manage cycles of concentration in cooling towers.Proper treatment helps maintain water quality and efficiency, which is crucial for achieving higher cycles of concentration without causing scale and corrosion problems1.
