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

Answer : D

The Indoor Environmental Quality Prerequisite for Minimum Indoor Air Quality Performance has a minimum occupancy requirement to ensure that indoor air quality (IAQ) assessments accurately reflect the conditions experienced by building occupants. This prerequisite focuses on achieving acceptable IAQ within the building by meeting or exceeding local codes or ASHRAE standards, ensuring the health and well-being of the occupants. Reference: The LEED O+M Reference Guide's Indoor Environmental Quality section details the requirements for maintaining minimum IAQ performance, including the importance of considering occupancy levels in IAQ assessments.

Answer : D

According to the Sheet Metal and Air Conditioning National Contractors Association (SMACNA) Indoor Air Quality (IAQ) Guidelines for Occupied Buildings under Construction, the Minimum Efficiency Reporting Value (MERV) as determined by ASHRAE 52.2-2007 required for renovation activities is MERV 13. This requirement is in place to ensure that the air filtration systems used during renovation activities are capable of capturing fine particles, thus reducing the risk of indoor air quality issues. MERV 13 filters are efficient at capturing particles that are 0.3 to 1.0 micrometers in size, including dust, pollen, mold spores, bacteria, and any other airborne contaminants that might be present during construction activities. Reference: SMACNA IAQ Guidelines for Occupied Buildings Under Construction, 2nd Edition 2007; ASHRAE Standard 52.2-2007, 'Method of Testing General Ventilation Air-Cleaning Devices for Removal Efficiency by Particle Size.'

Answer : D

This credit has exemplary performance because it allows projects to earn an additional point by reducing outdoor water use by 75% or more from the calculated baseline1. The credit requires projects to reduce outdoor water use by at least 50% from the calculated baseline, which is determined by the EPA WaterSense Water Budget Tool2. The credit encourages projects to use native or adapted plants, efficient irrigation systems, alternative water sources, or no irrigation at all.

Answer : C

The building engineer is ideally positioned to serve as the Indoor Environmental Quality Manager for implementing the Indoor Environmental Quality Credit, Indoor Environmental Quality Management Program. Their expertise in building systems and operations ensures that indoor environmental quality strategies are effectively integrated into the building's daily maintenance and operation procedures, enhancing the well-being of occupants.

Reference: The role and responsibilities of the Indoor Environmental Quality Manager in implementing the Indoor Environmental Quality Management Program are detailed in the LEED AP Operations + Maintenance reference materials. These resources underline the importance of having a dedicated professional, like a building engineer, oversee indoor environmental quality initiatives.

Answer : A

The LEED AP Operations + Maintenance (LEED AP O+M) V4.1 rewards customers who change their normal consumption patterns in response to the varying price of energy over time under the Energy and Atmosphere Credit, Demand Response. This credit encourages building owners and operators to participate in demand response programs which aim to shift the timing of energy use to off-peak periods when demand on the grid is lower. This helps to reduce the strain on the grid during peak demand periods, potentially avoiding the need for additional power plants.

Answer : C

Installing and maintaining a conductivity meter is a strategy that improves cooling tower water efficiency. Conductivity meters help optimize the cycles of concentration, reducing water and chemical use by accurately measuring the water's mineral content.

Answer : D

The correct answer is D because maintenance equipment is not a topic that is required to be addressed in the Site Improvement Plan for the Sustainable Sites Credit, as stated in the LEED v4.1 O+M Reference Guide1. The Site Improvement Plan must include topics such as soils, hydrology, vegetation, and site management, and describe the existing conditions, goals, strategies, and performance metrics for each topic1. The other options are incorrect because they are topics that are required to be addressed in the Site Improvement Plan.

In order to comply with the Sustainable Sites Credit, Site Improvement Plan, addressing the topics of soils, hydrology, and vegetation is essential. These elements are crucial for ensuring sustainable site management, enhancing site ecology, managing stormwater, and promoting biodiversity. However, the topic of maintenance equipment, while important for operational considerations, is not directly necessary for compliance with this specific credit. The focus of the Site Improvement Plan is on the physical and ecological aspects of the site rather than the equipment used for site maintenance.
