QUESTION: 5

For projects not eligible for the ENERGY STAR® rating, the project team could demonstrate compliance with Energy and Atmosphere Prerequisite, Minimum Energy Efficiency Performance by

conducting an energy audit that develops a commissioning plan for the building's major energy using system
providing a program demonstrating no or low cost measures of improvement to increase energy efficiency
developing a master list of findings identifying systems or pieces of equipment including the defects or problems and proposed solutions
demonstrating an energy efficiency of at least 25% better than the national average for typical buildings of similar type based on energy source

Answer(s): D

Explanation:

Projects not eligible for the ENERGY STAR rating must demonstrate an energy efficiency of at least 25% better than the national average for typical buildings of similar type based on energy source. This can be done by using the ENERGY STAR Target Finder tool or a custom approved by USGBC.

Reference:

LEED AP O+M Exam Guide, page 305; LEED v4.1 O+M Reference Guide, page 97.

For projects not eligible for the ENERGY STAR® rating, an alternative path to demonstrate compliance with the Energy and Atmosphere Prerequisite, Minimum Energy Efficiency Performance, is to show that the building's energy efficiency is significantly higher than the baseline established for similar buildings. Demonstrating energy efficiency that is at least 25% better than the national average for comparable buildings, based on the type of energy used, provides a quantifiable metric that reflects the building's superior performance. This approach aligns with LEED's goal to encourage higher energy efficiency standards and reduce environmental impact through improved building performance.

This alternative compliance path for projects not eligible for ENERGY STAR® rating is outlined in the LEED for Building Operations and Maintenance reference guide under the Energy and Atmosphere category. It provides a method for buildings to achieve the Minimum Energy Efficiency Performance prerequisite by exceeding the energy performance standards of similar buildings, promoting an advanced level of energy conservation in building operations as emphasized in LEED AP O+M training materials.

QUESTION: 6

What is the allowed maximum tenant space exclusion for Energy and Atmosphere Prerequisite, Minimum Energy Performance?

10% of the vacant space
10% of the gross floor area
10% of the project site area
10% of the regularly occupied area

Answer(s): B

Explanation:

The LEED AP Operations + Maintenance (LEED AP O+M) V4.1 guide specifies that for the Energy and Atmosphere Prerequisite, Minimum Energy Performance, the allowed maximum tenant space exclusion is 10% of the gross floor area. This means that when calculating energy performance, up to 10% of the total floor area of the building can be excluded. This could be due to various reasons such as spaces being unoccupied or not in use.

Reference:

LEED v4: Building Operations + Maintenance Guide, LEED v4: Building Design + Construction Guide, Minimum Energy Performance Calculator - ASHRAE 90.1 - 2010, LEED v4 energy update U.S. Green Building Council

The Energy and Atmosphere Prerequisite, Minimum Energy Performance, allows for certain exclusions to accommodate diverse building types and uses. One such provision permits the exclusion of up to 10% of the gross floor area (GFA) from the energy performance calculations. This allowance is designed to provide flexibility for spaces that may not be fully occupied or operational during the performance period, such as tenant spaces undergoing renovation or spaces with atypical energy usage. By excluding a limited portion of the GFA, the prerequisite acknowledges the variability in building occupancy and use, ensuring that the energy performance assessment is both fair and representative of the building's typical operations.

The allowance for excluding up to 10% of the gross floor area from the energy performance calculations is detailed in the LEED for Building Operations and Maintenance reference guide, specifically under the Energy and Atmosphere Prerequisite, Minimum Energy Performance. This guideline is part of the LEED AP O+M training materials, which emphasize the importance of accommodating diverse building uses and occupancy levels in the pursuit of sustainable building operations.

QUESTION: 7

The measures called out on the following site plan may contribute to the achievement of which LEED credits?
(Click on Exhibit)

Exhibit

Sustainable Sites Credit, Rainwater Management; Sustainable Sites Credit, Light Pollution Reduction
Sustainable Sites Credit, Rainwater Management; Sustainable Sites Credit, Heat Island Reduction
Sustainable Sites Credit, Rainwater Management; Location and Transportation Credit, Alternative Transportation
Sustainable Sites Credit, Rainwater Management; Indoor Environmental Quality Credit, Integrated Pest
Management

Answer(s): B

Explanation:

The site plan includes measures for managing rainwater and reducing heat islands. Rain gardens and permeable surfaces are indicated, contributing to the Sustainable Sites Credit for Rainwater Management. The inclusion of parking under the solar canopy contributes to the Heat Island Reduction credit by providing shade and reducing surface temperatures.

Reference:

LEED AP O+M Exam

The site plan provided indicates two distinct sustainability measures: rainwater management and vegetated roof implementation. Rainwater management pertains to strategies that manage and mitigate the impacts of rainfall runoff. It contributes to the Sustainable Sites Credit for Rainwater Management by reducing runoff volume and improving water quality, which is in line with LEED requirements for managing precipitation on-site. Additionally, the presence of a vegetated roof, as shown in the plan, is a strategy for mitigating heat islands. This contributes to the Sustainable Sites Credit for Heat Island Reduction, which aims to minimize the impact on microclimates and human and wildlife habitats by reducing heat-absorbing surfaces.

The LEED BD+C Reference Guide, specifically the Sustainable Sites (SS) category, outlines the importance of rainwater management and heat island reduction strategies. These are fundamental aspects covered in the LEED AP O+M training materials, which emphasize site sustainability as a critical component of the overall sustainability of a building project.

QUESTION: 8

Buildings account for what percentage of total energy use?

30%
40%
50%
60%

Answer(s): B

Explanation:

Buildings account for 40% of total energy use in the U.S., according to the U.S. Environmental Protection Agency1. This is consistent with the global estimate by the International Energy Agency, which states that buildings and construction sector accounted for 36% of final energy use in 20182.

Reference:

LEED AP O+M Exam Guide, page 305; LEED v4.1 O+M Reference Guide, page 97.

Buildings are one of the primary consumers of energy worldwide, and they account for a significant percentage of total energy use. The correct percentage is 40%, which encompasses energy used for heating, cooling, lighting, and operating buildings. This figure reflects the extensive impact that building design, construction, and operations have on energy consumption and the potential for energy savings in this sector.

The figure that buildings account for 40% of total energy use is a commonly cited statistic in the field of sustainability and is mentioned in LEED training materials and documentation. It is a crucial factor that drives the Energy and Atmosphere (EA) category within the LEED rating systems, pushing for strategies that reduce energy consumption and improve building energy performance.
