NEW QUESTION # 88
Which class of refrigerants contributes the most to ozone depletion potential (ODP)?
- A. Hydrofluorocarbons (HFCs)
- B. Ammonia (NH3)
- C. Hydrochlorofluorocarbons {HCFCs}
- D. Chlorofluorocarbons (CFCs)
Answer: D
Explanation:
Explanation
Chlorofluorocarbons (CFCs) are the class of refrigerants that contribute the most to ozone depletion potential (ODP). Ozone depletion potential is a measure of how much a substance can damage the ozone layer in the stratosphere, which protects life on Earth from harmful ultraviolet radiation. CFCs are synthetic chemicals that contain chlorine, fluorine, and carbon atoms. They were widely used as refrigerants, aerosol propellants, solvents, and foam blowing agents until they were phased out by the Montreal Protocol due to their high ODP.
The LEED Green Associate Candidate Handbook states that one of the strategies for achieving energy and atmosphere efficiency is to "eliminate chlorofluorocarbons (CFCs) in new building HVAC&R systems" [1, p.
15]. References: LEED Green Associate Candidate Handbook, [Ozone Depletion Potential | U.S.

NEW QUESTION # 91
Which of the following Is the recommended tool for the project team to utilize In order to determine the target certification level?
- A. It is not possible to estimate certification level without complete drawings
- B. Credit Submittal Form
- C. Scorecard
- D. Project CIR
Answer: C
Explanation:
Explanation
The scorecard is the recommended tool for the project team to utilize in order to determine the target certification level. The scorecard is a document that lists all the prerequisites and credits available for a specific rating system, along with their point values and requirements. The project team can use the scorecard to track their progress and estimate their potential score based on their design strategies and performance goals. The scorecard also helps the project team to identify synergies and trade-offs among different credits, prioritize their efforts, and optimize their resources.
The other options are not useful for estimating the certification level, as they are tools for documenting or clarifying specific credits or issues. The credit submittal form is a template that guides the project team on how to submit the required documentation for each credit. The project CIR (Credit Interpretation Request) is a service that allows the project team to ask technical questions or request clarifications on credit requirements or standards from USGBC or GBCI reviewers. The certification level cannot be determined without complete drawings, as they are necessary to demonstrate compliance with credit criteria.

NEW QUESTION # 94
Which of the following is a strategy that a design team should consider In order to decrease the Impact of a new construction project?
- A. Maximize views of the existing wetland
- B. Increase the project's footprint to maximize roof space for a solar array
- C. Select native plants to provide habitat for local fauna
- D. Locate the project in an existing office park with ample parking
Answer: C
Explanation:
Selecting native plants to provide habitat for local fauna is a strategy that a design team should consider in order to decrease the impact of a new construction project. Native plants are plants that have evolved in a specific region and have adapted to the local climate and soil conditions. Native plants can offer many benefits for the environment, such as:
* Reducing water use and runoff by requiring less irrigation and fertilization
* Enhancing biodiversity and ecosystem services by supporting native wildlife and pollinators
* Improving air quality and mitigating climate change by sequestering carbon and reducing greenhouse gas emissions
* Increasing soil health and stability by preventing erosion and improving infiltration
* Creating a sense of place and cultural identity by reflecting the natural heritage of the region The other options are not strategies that would decrease the impact of a new construction project. Maximizing views of the existing wetland may improve occupant satisfaction, but it does not necessarily reduce the environmental footprint of the project. Locating the project in an existing office park with ample parking may reduce land use and transportation impacts, but it may also increase heat island effect and stormwater runoff.
Increasing the project's footprint to maximize roof space for a solar array may increase renewable energy generation, but it may also increase site disturbance, material use, and energy demand. References: : Native Plants
NEW QUESTION # 95
Which of the following includes impacts quantified by life-cycle costing (CCC)?
- A. Energy use reduction
- B. Acidification reduction
- C. Eutrophication potential
- D. Global warming potential
Answer: A
Explanation:
Life-cycle costing (LCC) is a method of estimating the total cost of owning and operating an asset over its entire life span. LCC considers all costs associated with the acquisition, installation, operation, maintenance, and disposal of the asset12. LCC can help businesses make better decisions about purchasing, budgeting, pricing, and investing in assets2.
LCC does not quantify environmental impacts such as acidification, eutrophication, or global warming. These impacts are measured by life-cycle assessment (LCA), which is a method of evaluating the environmental effects of a product or service throughout its life cycle. LCA considers the inputs and outputs of materials, energy, and emissions at each stage of the product or service life cycle34. LCA can help businesses identify opportunities to reduce their environmental footprint, improve their sustainability performance, and comply with environmental regulations4.
However, LCC and LCA are often used together to compare different alternatives based on both economic and environmental criteri a. For example, a business may use LCC to estimate the energy costs of different lighting options, and LCA to estimate the greenhouse gas emissions of each option. By combining LCC and LCA results, the business can select the option that minimizes both costs and emissions.
NEW QUESTION # 96
Which of the following strategies will help to improve indoor air quality during construction?
- A. Select low Volatile Organic Compound (VOC) paints, adhesives. sealants and furniture
- B. Reduce outdoor air flow
- C. Designate a smoking room in the building
- D. Locate air intakes in the building loading dock area
Answer: A
NEW QUESTION # 97
Which of the following is a strategy for reducing indoor water use?
- A. Reuse Salvaged plumbing fixtures
- B. use graywater for hand washing
- C. Install submeters
- D. Install a time-sensitive drip irrigation system
Answer: B
Explanation:
Explanation
Using graywater for hand washing is a strategy for reducing indoor water use, as it can save potable water that would otherwise be used for this purpose. Graywater is the wastewater that is generated from activities such as bathing, laundry, and dishwashing, which can be treated and reused for non-potable applications, such as toilet flushing, irrigation, and hand washing. Using graywater for hand washing can reduce the indoor water use by up to 40%, according to a study by the Pacific Institute1. LEED v4 recognizes and rewards this strategy in the Indoor Water Use Reduction credit2, which aims to reduce the potable water consumption of a building by at least 25% compared to a baseline3. The other options are not directly related to reducing indoor water use, as they involve different types of measures or systems that are not relevant for saving potable water.
NEW QUESTION # 98

- A. Biomass
- B. Natural gas
- C. Clean coal
- D. Nu clear
Answer: A
NEW QUESTION # 99
Which of the following Is a measure of energy use intensity?
- A. Systems with ENERGY STAR" requirements
- B. The amount of electricity a wind turbine can produce
- C. Energy consumed per unit of floor space
- D. Daylighting and views
Answer: C
Explanation:
Energy use intensity (EUI) is a measure of energy use per unit of floor space. It is calculated by dividing the total energy consumed by the building in one year (measured in kilowatt-hours or kilo-British Thermal Units) by the total gross floor area of the building (measured in square feet or square meters). EUI is a useful metric for comparing the energy performance of different buildings or benchmarking against national averages. EUI can vary depending on building type, climate, occupancy, and other factors. Generally, a lower EUI indicates better energy efficiency and lower environmental impact.

NEW QUESTION # 100
Which strategy will help build consensus for a project's sustainability goals?
- A. Hosting a charrette
- B. Including LEED language in project specifications
- C. Survey building occupants
- D. Circulating a project scorecard
Answer: A
Explanation:
A charrette is a strategy that can help build consensus for a project's sustainability goals. A charrette is an intensive, collaborative, and creative workshop that brings together the project team and other stakeholders to define the project goals, scope, and strategies. A charrette can help to establish a common vision, identify synergies, and prioritize actions for a green building project. A charrette can also foster communication, trust, and buy-in among the participants13. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide3
NEW QUESTION # 101
Which strategy for roof coverage best addresses both heat island effect and rainwater runoff from the roof only?
- A. 100% vegetated
- B. 50% standing seam copper and 50% vegetated
- C. 20% high-albedo and 80% conventional
- D. 100% high-albedo
Answer: A
Explanation:
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.
NEW QUESTION # 102
Open grid pavement tends to reduce
- A. parking space requirements
- B. native habitat
- C. heat island effects
- D. rainwater infiltration
Answer: C
Explanation:
Open grid pavement, also known as permeable pavement, allows water to drain through it, reducing runoff and recharging groundwater supplies. It also tends to be lighter in color than traditional asphalt, which means it absorbs less heat from sunlight. This helps to reduce the urban heat island effect, which is a phenomenon where urban areas are significantly warmer than their rural surroundings due to human activities. References:
LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
NEW QUESTION # 103
Which describes the difference between graywater and blackwater?
- A. Graywater is approved for human consumption and may be supplied from wells or municipal water systems, whereas blackwater is comprised of wastewater from toilets and urinals
- B. Graywater includes wastewater from lavatory faucets, whereas blackwater includes waste water from toilets and urinals
- C. Graywater includes storm water and potable water, whereas blackwater Includes stormwater and Irrigation
- D. Graywater may be used for irrigation or drinking, but blackwater should only be used as a source of process water
Answer: B
Explanation:
Explanation
Graywater includes wastewater from lavatory faucets, whereas blackwater includes wastewater from toilets and urinals. This describes the difference between graywater and blackwater according to LEED. Graywater is wastewater that has been used for non-potable purposes, such as washing hands or dishes, but does not contain human or animal waste. Blackwater is wastewater that has been contaminated with human or animal waste from toilets or urinals. Graywater can be reused for certain purposes after minimal treatment, such as irrigation or toilet flushing, whereas blackwater requires more advanced treatment before reuse or disposal. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving water efficiency is to "use non-potable water (graywater) for sewage conveyance" [1, p. 14].

NEW QUESTION # 104
The maximum points a new construction platinum LEED for Neighborhood Development certification level can earn are
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
Explanation
The LEED for Neighborhood Development rating system has four certification levels: Certified, Silver, Gold, and Platinum. Each level requires a minimum number of points to achieve, based on the total number of available points in the rating system. The total number of available points is 110, and the minimum points for Platinum certification is 801. Therefore, the maximum points a new construction platinum LEED for Neighborhood Development certification level can earn are 110 - 80 = 30 points. However, there are also four regional priority credits that can be earned for addressing geographically specific environmental issues2.
These credits are worth one point each, and can be added to the total score of a project. Therefore, the maximum possible points a new construction platinum LEED for Neighborhood Development certification level can earn are 30 + 4 = 34 points. However, the question asks for the maximum points that can be earned by a new construction project. According to the LEED Reference Guide for ND, new construction projects must meet all prerequisites and achieve at least 50% of the points available under the Green Infrastructure and Buildings category3. This category has 21 criteria, each worth one point, except for Certified Green Buildings, which is worth up to five points4. Therefore, the maximum points available under this category are 21 + 4 =
25 points. Since new construction projects must achieve at least 50% of these points, they must earn at least 13 points under this category. This means that they have less points to earn under the other categories (Smart Location and Linkage, and Neighborhood Pattern and Design), which have a total of 32 criteria worth one point each4. Therefore, the maximum points a new construction project can earn under these categories are
110 - 25 - 13 = 72 points. Adding the regional priority credits, the maximum possible points a new construction project can earn are 72 + 4 = 76 points. To achieve Platinum certification, a new construction project must earn at least 80 points1. Therefore, the maximum points a new construction platinum LEED for Neighborhood Development certification level can earn are 80 - 76 = 4 points under each of the four categories: Smart Location and Linkage, Neighborhood Pattern and Design, Green Infrastructure and Buildings, and Regional Priority Credits. Hence, the answer is D. 16.

NEW QUESTION # 106
Minimum acoustic performance is a prerequisite requirement that applies to
- A. LEED for Hospitality
- B. LEED for Healthcare
- C. LEED for New Constructions and Major Renovations
- D. LEED for Schools
Answer: D
Explanation:
Explanation
Minimum acoustic performance is a prerequisite requirement that applies to LEED for Schools projects. The prerequisite aims to provide classrooms that facilitate better teacher-to-student and student-to-student communication through effective acoustic design. The prerequisite requires projects to meet the sound transmission class (STC) ratings for walls, floors, ceilings, doors, and windows; the background noise levels from HVAC systems; and the reverberation time for core learning spaces. By meeting the minimum acoustic performance, projects can improve the indoor environmental quality, enhance the learning outcomes, and reduce thehealth and stress impacts of noise.

NEW QUESTION # 107
Up lo how many maximum points can a project earn under the Regional Priority credit?
- A. Two
- B. Four
- C. Three
- D. One
Answer: B
Explanation:
A project can earn up to four maximum points under the Regional Priority credit. The Regional Priority credit is a bonus credit that rewards projects for addressing environmental issues that are of regional importance. The USGBC regional councils and chapters have identified six environmental issues for each zip code in the United States, and projects can earn one point for each issue they address, up to a maximum of four points. The other options are not correct. One, two, or three points are possible, but not the maximum number of points under the Regional Priority credit. Reference: LEED Green Associate Candidate Handbook, page 30; USGBC, [Regional Priority], page 1.
