QUESTION 137
Good site design benefits a project in which of the following ways?

Makes occupants comfortable by providing green spaces

Supports access to diverse land uses, sustainable food and services

Provides access to public transportation and employment opportunities

Protects endangered species and maximizes development of previously undeveloped areas

Explanation
Good site design benefits a project in which of the following ways: makes occupants comfortable by providing green spaces. Green spaces are areas of vegetation that improve the quality of life for building occupants and visitors by providing natural views, fresh air, shade, noise reduction, and recreational opportunities. They also reduce heat island effect, improve stormwater management, and sequester carbon dioxide. The LEED Green Associate Candidate Handbook states that one of the intents of the Sustainable Sites category is to “enhance occupant comfort by providing green spaces” [1, p. 13].

QUESTION 138
Light trespass beyond the project boundary can be prevented by the use of

flood light fixtures

up-lighting fixtures

shielded light fixtures

increasing the number of light fixtures

Shielded light fixtures are designed to direct light downwards and prevent it from spilling over into areas where it’s not wanted, such as beyond the project boundary. This helps to prevent light trespass, which can be a form of pollution that disrupts ecosystems and human sleep patterns.

QUESTION 139
A project has 16 employees working for four hours per day, 20 employees working six hours per day, and 10 employees working eight hours per day. What is the Full Time Equivalent (FTE) occupancy of the project?

Explanation
The Full Time Equivalent (FTE) occupancy of a project is a measure of how many people occupy a building or space on a regular basis. The FTE occupancy is calculated by dividing the total number of hours worked by all occupants in a week by the standard weekly hours for one FTE occupant. The standard weekly hours for one FTE occupant is typically 40 hours per week1 . For this project, the FTE occupancy is calculated as follows:
16 employees x 4 hours/day x 5 days/week = 320 hours/week 20 employees x 6 hours/day x 5 days/week =
600 hours/week 10 employees x 8 hours/day x 5 days/week = 400 hours/week Total hours/week = 1320 hours/week FTE occupancy = 1320 hours/week / 40 hours/week = 33 Therefore, the FTE occupancy of the project is 33. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide

QUESTION 140
Which of the following is the reason Regional Priority credits are awarded?

To help meet economic goals

To encourage exemplary performance

To address local environmental issues

To promote innovation in building design

Regional Priority credits are awarded to encourage projects to address local environmental issues that are of particular importance or concern for the region where the project is located. These issues may include water scarcity, air quality, habitat protection, or human health. Regional Priority credits are not new LEED credits, but rather existing credits that have been identified by regional councils or chapters of USGBC as having higher priority or relevance for their areas. Projects can earn up to four bonus points by achieving Regional Priority credits. Reference: LEED v4 BD+C Reference Guide, Introduction, page 13; LEED v4 Impact Category and Point Allocation Process Overview1

QUESTION 141
Which of the following is a prerequisite in LEED v4 Water Efficiency category?

Rainwater Management

Cooling Tower Water Use

Building-Level Water Metering

Building-Level Energy Metering

Explanation
Building-Level Water Metering is a prerequisite in LEED v4 Water Efficiency category. Building-Level Water Metering means that the project must install permanent water meters that measure the total potable water use for the building and associated grounds. The project must also commit to sharing the water usage data with USGBC for at least five years after occupancy or certification. The LEED Green Associate Candidate Handbook states that this is one of the two prerequisites in the Water Efficiency category [1, p.
14]. References: [LEED Green Associate Candidate Handbook], [Building-Level Water Metering | U.S. Green Building Council]

QUESTION 142
In addition to the temperature and air movement, what is another factor to consider when implementing Thermal Comfort strategies?

Humidity

Methane off-gassing

Carbon dioxide concentrations

Combustion processes from vehicles

Explanation
In addition to temperature and air movement, humidity is another factor to consider when implementing thermal comfort strategies. Humidity is the amount of water vapor in the air, which affects how warm or cool people feel. High humidity can make people feel hotter and more uncomfortable, while low humidity can cause dryness and irritation of the skin, eyes, nose, and throat. Thermal comfort strategies should aim to maintain an optimal level of humidity that balances human comfort and health with energy efficiency and moisture control. The other options are not factors to consider when implementing thermal comfort strategies.
Methaneoff-gassing is the release of methane gas from organic matter decomposition or anaerobic digestion, which contributes to greenhouse gas emissions and climate change. Carbon dioxide concentrations are a measure of indoor air quality that indicates the level of ventilation and fresh air supply in a space. Combustion processes from vehicles are sources of outdoor air pollution that emit carbon monoxide, nitrogen oxides, particulate matter, and other harmful substances. References: LEED Green Associate Candidate Handbook, page 29; USGBC, [Indoor Environmental Quality], page 2.

QUESTION 143
Which impact categories have been identified as most important for a LEED project to accomplish?

Increase return on investment, promote human scale development

Protect biodiversity and ecosystem services, improve business efficiency

Reduce contribution to climate change, enhance human health and well-being

Increase return on investment, promote sustainable and regenerative material cycles

The LEED rating system is designed to address the most important environmental impacts and human benefits of green building. The impact categories are based on the U.S. Environmental Protection Agency’s TRACI method (Tool for the Reduction and Assessment of Chemical and Other Environmental Impacts), which evaluates the potential environmental effects of a product or process over its life cycle. The impact categories are: reverse contribution to global climate change; enhance individual human health and well-being; protect and restore water resources; protect, enhance and restore biodiversity and ecosystem services; promote sustainable and regenerative material cycles; build a greener economy; enhance social equity, environmental justice, community health and quality of life. Among these categories, reducing contribution to climate change and enhancing human health and well-being have been identified as the most important ones for a LEED project to accomplish.

QUESTION 151
Which of the following is a minimum program requirement for the LEED for New Construction and Major Renovations Rating System?

Comply with minimum project size

Include temporary structures in floor area calculations

Define a site boundary for the sole purpose of complying with credits

Comply with the best practices of the International Organization for Standardization (ISO)

The minimum program requirements (MPRs) are the basic characteristics that a project must possess in order to be eligible for LEED certification. One of the MPRs for the LEED for New Construction and Major Renovations Rating System is to comply with the minimum project size, which is defined as having a gross floor area of at least 1,000 square feet (93 square meters) that is capable of achieving a minimum level of energy efficiency13. Reference: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide3

QUESTION 152
A building is located on a site without access to public transportation. Which of the following strategies can a project team implement in order to reduce the environmental impacts associated with how the occupants get to and from the building?

Limit parking

Provide incentives for carpooling

Build underground parking structure

Use compact development strategies

Explanation
A building that is located on a site without access to public transportation can have a high environmental impact associated with how the occupants get to and from the building, such as greenhouse gas emissions, air pollution, energy consumption, and traffic congestion. One of the strategies that a project team can implement in order to reduce this impact is to provide incentives for carpooling, which is a form of alternative transportation that involves sharing a vehicle with other passengers who have similar travel routes or destinations. Providing incentives for carpooling can encourage the occupants to reduce their single-occupancy vehicle trips and use fewer vehicles, which can save fuel, reduce emissions, and lower parking demand. Some examples of incentives for carpooling are: subsidies, vouchers, discounts, prizes, recognition, or preferential parking12.
