LEED-AP-O-M Exam Questions and Answers

QUESTION: 21

The project team is attempting to achieve Option 1. Lighting Controls in Indoor Environmental Quality Credit, Interior Lighting.
Which of the following is required documentation?

Table of lighting controls installed
Manufacturers' data for occupancy sensors
The total area of the building square footage
A photometric chart of the multi-occupant space

Answer(s): A

Explanation:

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.

QUESTION: 22

A project is ineligible for an ENERGY STAR® Rating and will document Energy and Atmosphere Prerequisite,
Minimum Energy Performance by benchmarking against historical dat

If the performance period calendar year is
2022, which of the following is an acceptable historical baseline?
Average of calendar years 2020 and 2021
Average of calendar years 2015, 2016 and 2017
Average of calendar years 2017, 2019 and 2021
Average of calendar years 2017, 2018 and 2019

Answer(s): D

Explanation:

The correct answer is D because the historical baseline must be the average of the most recent three consecutive years of energy data available prior to the performance period1. Since the performance period calendar year is 2022, the most recent three consecutive years of energy data available are 2017, 2018 and 2019. The other options are incorrect because they either include years that are not consecutive or not prior to the performance period.

Reference:

LEED v4.1 O+M Reference Guide, page 139
Guide to the LEED AP Operations and Maintenance (O+M) Exam, page 89 LEED v4 AP O+M Mock Exam, page 85
When a project is ineligible for an ENERGY STAR® Rating and opts to document Energy and Atmosphere Prerequisite, Minimum Energy Performance by benchmarking against historical data, the selected baseline must be representative of the building's typical performance. The average of calendar years 2017, 2018, and 2019 serves as a relevant baseline because it provides recent, consecutive annual data that reflects the building's energy performance before any significant changes or improvements made for LEED certification. This approach ensures that the performance period (in this case, the calendar year 2022) is compared against a stable and accurate representation of the building's typical energy use, allowing for a meaningful assessment of energy performance improvements.

QUESTION: 23

In following the Sheet Metal and Air Conditioning National Contractors Association (SMACNA) Indoor Air Quality (IAQ) Guidelines for Occupied Buildings under Construction, what is the Minimum Efficiency Reporting Value (MERV)
as determined by ASHRAE 52.2-2007 required for renovation activities?

7
8
12
13

Answer(s): D

Explanation:

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.

QUESTION: 24

The project team of an existing urban site has 4% total vegetated area and desires to increase the percentage to equal or be greater than 5%.
Which strategy can the team implement to achieve this goal?

Install a vegetated roof system
Convert lawn areas to native plants
Mitigate the vegetated area off-site through a land trust
Convert the paved areas of the site to pervious pavement

Answer(s): A

Explanation:

To increase the vegetated area of an existing urban site from 4% to equal or be greater than 5%, one effective strategy is to install a vegetated roof system. This approach not only increases the site's vegetated footprint but also provides additional benefits such as improved stormwater management, increased insulation, and reduction of the urban heat island effect. A vegetated roof system can be implemented on flat or slightly sloped roofs, making it a versatile option for urban environments where ground space may be limited. By converting unused roof space into green space, the project team can meet the goal of increasing the total vegetated area of the site.

QUESTION: 25

Which of the following topics is unnecessary in order to comply with the Sustainable Sites Credit, Site Improvement
Plan?

Soils
Hydrology
Vegetation
Maintenance equipment

Answer(s): D

Explanation:

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.

Reference:

LEED v4.1 O+M Reference Guide, page 115
Guide to the LEED AP Operations and Maintenance (O+M) Exam, page 80 LEED v4 AP O+M Mock Exam, page 86

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.
