Designers and builders can construct a green building that uses significantly less water than a

conventional building by incorporating native plant landscapes. Native plant landscapes are plants

that are adapted to the local climate and soil conditions, and require little or no irrigation,

fertilization, or pesticides. They also provide habitat for wildlife, reduce stormwater runoff, and

enhance the aesthetic value of the site. The LEED Green Associate Candidate Handbook states that

one of the intents of the Sustainable Sites category is to “conserve water by using native or adapted

plants” [1, p. 13]. Reference: [LEED Green Associate Candidate Handbook], [Native Plants | U.S.

Environmental Protection Agency]

One of the causes of surface water degradation is the expansion of impervious surfaces. Impervious

surfaces are those that do not allow water to infiltrate into the soil, such as roads, parking lots,

rooftops, and sidewalks. Impervious surfaces increase the amount and speed of stormwater runoff,

which can carry pollutants, sediments, nutrients, and pathogens into surface water bodies such as

streams, rivers, lakes, and oceans. Impervious surfaces also reduce groundwater recharge, lower

base flow in streams, increase flooding and erosion, alter stream morphology and habitat, and affect

water temperature and dissolved oxygen levels2. Therefore, impervious surfaces can have significant

negative impacts on the quality and quantity of surface water resources. Reference: Surface Water as

a cause of land degradation from dryland salinity3; What is Water Pollution?4

LEED encourages compact communities because they provide reduction in travel associated with

reaching services. Compact communities are communities that have high-density development

patterns, mixed land uses, walkable streets, and diverse transportation options. Compact

communities reduce the need for driving long distances to access various services, such as work,

education, health care, recreation, or shopping. This reduces fuel consumption, greenhouse gas

emissions, air pollution, traffic congestion, and infrastructure costs. The LEED Green Associate

Candidate Handbook states that one of the intents of the Location and Transportation category is to

“reduce vehicle miles traveled (VMT)” [1, p. 12]. Reference: LEED Green Associate Candidate

Handbook, [Compact Communities | U.S. Department of Housing and Urban Development]

A 100% vegetated roof coverage best addresses both heat island effect and rainwater runoff from the

roof only. A vegetated roof, also known as a green roof, is a layer of living plants that covers the roof

surface. A vegetated roof reduces the heat island effect by providing shade, evapotranspiration, and

insulation, lowering the roof temperature and the surrounding air temperature. A vegetated roof

also reduces rainwater runoff by retaining and absorbing precipitation, decreasing the volume and

peak flow of stormwater leaving the roof. The other options are not as effective as a 100% vegetated

roof coverage in addressing both heat island effect and rainwater runoff from the roof only. A 100%

high-albedo roof reflects more solar radiation than a conventional roof, reducing the heat island

effect, but it does not reduce rainwater runoff. A 20% high-albedo and 80% conventional roof has a

lower reflectance than a 100% high-albedo roof, resulting in a higher heat island effect, and it does

not reduce rainwater runoff either. A 50% standing seam copper and 50% vegetated roof has a lower

vegetated area than a 100% vegetated roof, resulting in less shade, evapotranspiration, insulation,

retention, and absorption, leading to a higher heat island effect and more rainwater

runoff. Reference: LEED Green Associate Candidate Handbook, page 27; USGBC, [Sustainable Sites],

page 3.

Gallons per minute or liters per minute refers to the amount of water used by flow fixtures in LEED.

Flow fixtures are fixtures that deliver a constant stream of water, such as faucets, showerheads, or

hose bibs. The flow rate of these fixtures is measured in gallons per minute (gpm) or liters per

minute (L/min), which indicates how much water flows through them in a given time period. The

LEED Green Associate Candidate Handbook states that one of the strategies for achieving water

efficiency is to “use low-flow faucets and showerheads (maximum 2.5 gpm at 80 psi)” [1, p.

14]. Reference: LEED Green Associate Candidate Handbook, [Water Efficiency | U.S. Department of

Energy]

Increasing the amount of ventilation in an occupied space affects the Indoor Environmental Quality

credit category. Ventilation is the process of supplying fresh outdoor air and removing stale indoor air

from a building. Ventilation can improve the indoor environmental quality by diluting or removing

indoor pollutants, such as carbon dioxide, volatile organic compounds, or particulate matter, and

enhancing the thermal comfort and well-being of the occupants. The LEED Green Associate

Candidate Handbook states that one of the strategies for achieving indoor environmental quality is to

“increase ventilation rates” [1, p. 16]. Reference: LEED Green Associate Candidate Handbook,

[Ventilation | U.S. Department of Energy]

The U.S. Green Building Council (USGBC) administers the LEED rating systems development. The

LEED rating systems are frameworks that provide guidance and criteria for designing, constructing,

operating, and maintaining green buildings. The USGBC is responsible for developing, maintaining,

and updating the LEED rating systems through a consensus-based process that involves various

stakeholders, such as technical experts, industry leaders, government representatives, and public

comments. The LEED Green Associate Candidate Handbook states that “USGBC is committed to

transforming the way our buildings are designed, constructed and operated through LEED” [1, p.

7]. Reference: LEED Green Associate Candidate Handbook, [LEED Rating Systems | U.S. Green

Building Council]

The integrative process involves collaboration among all project team members, from initial planning

through design and construction, to enhance the efficiency and effectiveness of systems. This process

allows for better coordination among disciplines, leading to more efficient use of resources,

improved environmental performance, reduced project costs, and enhanced occupant

satisfaction. Reference: LEED Green Associate Candidate Handbook, U.S. Green Building Council

A neighborhood that includes a diversity of uses is most appropriate to encourage a walkable street

design. A diversity of uses means that different types of activities and functions are located within

walking distance of each other, such as residential, commercial, retail, educational, recreational,

cultural, and civic uses. A diversity of uses creates a vibrant and lively neighborhood that attracts

pedestrians and supports social interaction. A walkable street design also incorporates elements

such as sidewalks, crosswalks, street trees, lighting, benches, bike lanes, public transit stops, and

reduced vehicle speeds to enhance pedestrian safety and comfort. The other options are not

appropriate to encourage a walkable street design. An area with a decreased building-height-to-

street-width ratio creates a wide and open street that exposes pedestrians to more sun and wind,

reducing their comfort level. A development that uses many culs-de-sac in the street design creates a

disconnected and irregular street network that limits pedestrian access and mobility. A project in an

area designed with streets to facilitate increased speed limits prioritizes vehicle movement over

pedestrian safety and comfort. Reference: LEED Green Associate Candidate Handbook, page 29;

USGBC [Location & Transportation], page 2-3.

Unless mitigated, resource consumption over the life of a conventional building incrementally

increases the total emissions footprint. This is because conventional buildings often use non-

renewable resources for energy and materials, which contribute to greenhouse gas emissions during

extraction, production, use, and disposal. Reference: LEED Green Associate Candidate Handbook,

U.S. Green Building Council resources

Green power, like all electricity, is typically purchased in units of kilowatt-hours (kWh). This unit

measures the amount of energy used over time. For example, a 1-kilowatt (1000 watts) appliance

used for one hour consumes one kilowatt-hour of electricity. Reference: LEED Green Associate

Candidate Handbook, U.S. Green Building Council resources

The credit templates are the online forms that document the achievement of the LEED credits for a

project pursuing LEED certification. The credit templates are completed and signed by the specified

team member who is responsible for the credit, such as the architect, engineer, contractor, or

owner. The team member must provide the required information, calculations, narratives, and

supporting documentation for each credit13. Reference: LEED v4 Green Associate Candidate

Handbook1, LEED v4 BD+C Reference Guide3

Monitoring outdoor airflow is a strategy for improving indoor environmental quality during

construction. Outdoor airflow is the amount of fresh air that enters a building through natural or

mechanical means. Monitoring outdoor airflow can help ensure that adequate ventilation is

provided to the building during construction, which can prevent the accumulation of indoor

pollutants, such as dust, debris, or volatile organic compounds, that may affect the health and

comfort of the workers or occupants. The LEED Green Associate Candidate Handbook states that one

of the strategies for achieving indoor environmental quality is to “monitor outdoor airflow” [1, p.

16]. Reference: LEED Green Associate Candidate Handbook, [Outdoor Airflow | ASHRAE]

The result of proper design and operation of buildings and neighborhoods is an increase in energy

efficiency. Energy efficiency is the ratio of useful output to energy input for a system or process.

Energy efficiency can be improved by using less energy to perform the same function or by using

renewable or low-impact energy sources. Energy efficiency can reduce greenhouse gas emissions,

energy costs, and dependence on fossil fuels1 . Reference: LEED v4 Green Associate Candidate

Handbook1, EPA’s Energy Efficiency

Chlorofluorocarbons (CFCs) are a type of compound that was widely used in the 20th century in

various applications, including as a refrigerant in air conditioning systems such as centrifugal chillers.

CFCs are known to deplete the ozone layer when released into the atmosphere, and their use has

been phased out in many countries under the Montreal Protocol. Reference: LEED Green Associate

Candidate Handbook, U.S. Green Building Council resources

The scope of the LEED impact category component Protect Human Health from Direct Exposure to

Negative Health Impacts is building occupants and design and construction crew during the

construction phase and use phase of the building cycle, within the project boundary and its

immediate surroundings. This component aims to reduce the exposure of people to harmful

substances or conditions that may affect their health and well-being. This includes indoor air quality,

thermal comfort, lighting quality, noise levels, water quality, and safety hazards. The component

covers both the construction phase and the use phase of the building cycle, as both stages can pose

potential health risks to people involved or affected by the project. The component also considers

both the project boundary and its immediate surroundings, as some health impacts may extend

beyond the site itself. Reference: LEED v4 BD+C Reference Guide, Introduction, page 9

According to the Indoor Environmental Quality credit category of LEED, mechanical and electrical

rooms are considered unoccupied spaces. These spaces are typically not intended for human

occupancy, except for maintenance or operational purposes, and therefore do not require the same

level of environmental control (such as ventilation or temperature control) as occupied

spaces. Reference: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

One of the requirements for the Sustainable Sites Credit: Rainwater Management is that projects

must use Green Infrastructure (GI) and Low Impact Development (LID) techniques within the LEED

project boundary. GI and LID are design approaches that mimic natural hydrologic processes to

manage stormwater runoff at its source. GI and LID techniques include strategies such as rain

gardens, bioswales, permeable pavements, green roofs, rain barrels, cisterns, and vegetated buffers.

The other options are not requirements for the Sustainable Sites Credit: Rainwater Management.

Maximizing open space within the LEED project boundary is a requirement for the Sustainable Sites

Credit: Open Space. Calculating the total rainwater runoff for 75th percentile rainfall events is a

requirement for the Sustainable Sites Credit: Site Assessment. Using a combination of both structural

and non-structural measures to manage a 90th percentile rainfall event is an option for meeting

Option 1 of the Sustainable Sites Credit: Rainwater Management. Reference: LEED Green Associate

Candidate Handbook, page 27; USGBC, [Sustainable Sites], page 4-5.

The Facilities Manager is typically responsible for ensuring the comfort and safety of a building’s

occupants. They would be best equipped to evaluate responses to a survey about comfort levels in

the building and develop a corrective action plan to address any problems identified. Reference:

LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

The amount of landfill-destined waste generated during project construction can be reduced by

requiring the general contractor to follow requirements for using dimensional construction

materials, prefabrication or material efficient framing. These methods reduce the amount of

material waste by minimizing cutting, fitting, and trimming on site, and by using standardized or

modular components that can be easily reused or recycled. The LEED Green Associate Candidate

Handbook states that one of the strategies for achieving materials and resources efficiency is to

“reduce construction waste through efficient framing techniques” [1, p. 15]. Reference: LEED Green
