LEED-Green-Associate USGBC LEED Green Associate Exam (LEED GA) Free Practice Exam Questions (2025 Updated)

The Guide specifies:

“Use nonpotable water for irrigation such as captured rainwater, graywater or municipally reclaimed wastewater…”

Potable water use is discouraged, and blackwater cannot be used unless treated.

LEED certification is awarded based on the number of points a project earns across several categories of green building performance. The range of points required to achieve LEED Silver is 50-59, out of a possible 110 points. The other levels of LEED certification are: Certified (40-49 points), Gold (60-79 points), and Platinum (80 or more points)12. Therefore, if a project initially has 34 credit points,it would need 20 additional points to reach the minimum threshold for LEED Silver. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide2

A charrette is an intensive, multi-disciplinary workshop with the aim of developing a design or vision for a project or planning activity. Charrettes are often conducted to design such things as parks and buildings, or to plan communities or transportation systems. A charrette should take place at the beginning of the project, when the design team can engage with all the stakeholders, including the client, users, consultants, contractors, regulators, and community members. A charrette at this stage can help to:

Establish clear goals and objectives for the project

Identify opportunities and constraints for the site and program

Generate creative and innovative ideas and solutions

Foster collaboration and consensus among diverse perspectives

Reduce conflicts and delays during later phases of the project

Enhance communication and trust among the project team

The other options are not appropriate phases for a charrette. Post commissioning is too late to influence the design or planning of the project. During the design process, some decisions may have already been made or some stakeholders may have been excluded. During the construction process, changes may be costly or impractical to implement. References: : Charrette

Strategies for improving building occupants’ comfort and control may consist of installing operable windows, giving occupants lighting control and providing ergonomic furniture. These strategies can enhance the indoor environmental quality (IEQ) of a building, which is the physical and psychological conditions of the indoor spaces that affect the health, comfort, and productivity of the occupants. Installing operable windows can allow occupants to adjust the natural ventilation, temperature, and fresh air intake of their spaces. Giving occupants lighting control can allow them to adjust the artificial lighting levels, color, and direction of their spaces. Providing ergonomic furniture can support the physical comfort, posture, and well-being of the occupants12. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide2

The Energy and Atmosphere (EA) category addresses the energy performance, efficiency, and renewable sources of buildings. One of the credits in this category is EA Credit: Enhanced Refrigerant Management, which aims to reduce the emissions of ozone-depleting substances and greenhouse gases from refrigeration and air-conditioning equipment. Refrigerants are substances that are used to transfer heat in cooling systems. Some refrigerants have high global warming potential (GWP) and ozone depletion potential (ODP), which means they can contribute to climate change and damage the ozone layer if they leak or are improperly disposed of. Enhanced refrigerant management involves selecting refrigerants with low GWP and ODP, minimizing refrigerant charge size, and preventing or detecting leaks12. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide2

A site map is required to show the locations of community resources within the specified radius to meet Location and Transportation credits. It visually demonstrates compliance with LEED requirements for access to diverse uses​​.

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. Methane off-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.

LEED MPRs state:

“Must be in a permanent location on existing land… Must use reasonable LEED boundaries… Must comply with project size requirements: BD+C and O+M: minimum 1,000 sq ft…”

Only option B satisfies all these conditions.

The minimum program requirements (MPRs) are the basic characteristics that a project must possess in order to be eligible for LEED certification. One of theMPRs 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. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide3

Implementing a stormwater pollution prevention plan during construction can help projects meet on-site sustainability goals. This plan outlines measures to control runoff and prevent soil erosion, which can carry pollutants into nearby water bodies. By managing stormwater on-site, projects can protect local water quality while also recharging groundwater supplies. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

The triple bottom line is a business concept that states firms should commit to measuring their social and environmental impact—in addition to their financial performance—rather than solely focusing on generating profit, or the standard “bottom line”1. The triple bottom line can be broken down into “three P’s”: profit, people, and the planet2. Firms can use these categories to conceptualize their environmental responsibility and determine any negative social impacts to which they might be contributing1.

Sustainable forestry is the practice of managing forest resources in a way that meets the current and future needs of humans forforest products, while also conserving and enhancing the ecological, social, and economic values of the forest and its surrounding landscape1. One of the key aspects of sustainable forestry is to maintain the biodiversity of the forest, which refers to the variety and abundance of living organisms, such as plants, animals, fungi, and microorganisms, and their interactions within the forest ecosystem2. Biodiversity is important for the health and resilience of the forest, as it provides essential ecosystem services, such as carbon sequestration, water purification, soil formation, nutrient cycling, pollination, pest control, and climate regulation23. Biodiversity also supports the livelihoods, cultures, and well-being of forest-dependent communities and indigenous peoples23.

Per the LeadingGreen Study Guide:

“LEED points are awarded on a 100-point scale. Additionally, 10 bonus credits are available: six Innovation and four Regional Priority credits.”

This totals 110 maximum points.

Building-level energy metering is a prerequisite in LEED that requires the installation of energy meters to track the total energy usage of a building12. It helps to monitor and optimize the energy performance of the building and to report the data to USGBC3. Green metering, site evaluation data, and energy savings records are not terms used in LEED.

The protection and restoration of natural vegetation, wetland areas and bodies of water through building footprint consolidation helps to preserve open space and sensitive areas, which are important for maintaining biodiversity, ecosystem services, and human well-being. Building footprint consolidation refers to the strategy of minimizing the area of land that is occupied by a building and its associated infrastructure, such as roads, parking lots, and utilities. By reducing the building footprint, project teams can avoid or minimize the impacts of development on natural habitats, wetlands, and water bodies, which often provide critical functions such aswater quality improvement, flood control, wildlife habitat, and recreation. LEED v4.1 recognizes and rewards this strategy in the Sensitive Land Protection credit1, which aims to conserve existing natural areas and restore damaged areas to provide habitat and promote biodiversity2. References: LEED Link: Sensitive Land Protection, section “LEED v4.1 BD+C: Sensitive Land Protection”; Sensitive Land Protection | U.S. Green Building Council, section “Intent”
