US Green Building Council LEED AP Operations + Maintenance LEED-AP-O+M Exam Questions

Answer : D

The LEED AP O+M Reference Guide states that ''If a meter fails during the performance period, the project team must extend the performance period to obtain the required three months of data.'' Therefore, the best advice is to extend the performance period to gain the full three months of weekly water meter readings.

Answer : B

The Water Efficiency Prerequisite, Indoor Water Use Reduction, under LEED AP O+M V4.1, includes the reduction of water use in various indoor appliances. The appliances included in this prerequisite are those that contribute significantly to indoor water use. Among the options provided, residential clothes washers and dishwashers are included.These appliances use a significant amount of water and are therefore important targets for water use reduction1.

Answer : B

This answer is correct because private use refers to lavatory faucets that are not for common use and are intended for the exclusive use of specific occupants. According to the LEED v4 Indoor Water Use Reduction Calculator1, private use applies to the following types of occupants: apartment residents, motel guests, nursing home residents, and dorm residents. The other options are incorrect because they either include common use lavatory faucets (such as prisoners, hospital staff, hotel guests, and fire-station staff) or do not include lavatory faucets at all (such as hospital inpatients and hotel staff).

Answer : B

The view factor is the percentage of the floor area that has a direct line of sight to the perimeter vision glazing. According to the LEED Reference Guide for Building Operations and Maintenance, the view factor for the diagram below is 2, which means that 75% or more of the floor area has a direct line of sight to the perimeter vision glazing.

Answer : C

The use of products with low emissions is a strategy that reduces the impact of materials used in building operation and maintenance on indoor air quality. These products, which include paints, adhesives, furniture, and flooring, emit fewer volatile organic compounds (VOCs) and other harmful substances into the indoor environment, thereby improving indoor air quality.

Answer : B

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.

Reference: 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.

Answer : A

Soil testing is an operational element that needs to be tracked only once during the performance period to meet the Sustainable Sites, Site Management Credit. This is because soil testing provides a snapshot of the soil's condition, which is unlikely to change significantly over short periods.
