NEW QUESTION # 19
What is the best way to prevent a building's indoor pollutant(s)?
- A. Test for radon
- B. Monitor carbon dioxide
- C. Remove any pollutants that enter the building
- D. Eliminate or control pollutants at the source
Answer: D
Explanation:
Explanation
The best way to prevent a building's indoor pollutant(s) is to eliminate or control pollutants at the source.
Indoor pollutants are substances or particles that can adversely affect the indoor air quality (IAQ) of a building and the health, comfort, and productivity of the occupants. Indoor pollutants can originate from various sources, such as building materials, furnishings, cleaning products, combustion appliances, outdoor air, or occupant activities. Eliminating or controlling pollutants at the source can prevent them from entering or spreading in the indoor environment, which can reduce the exposure and risk for the occupants. Some examples of source control strategies are: using low-emitting materials, installing local exhaust ventilation, sealing combustion appliances, implementing green cleaning practices, and prohibiting smoking13. References: LEED v4 Green Associate Candidate Handbook1, EPA's Indoor Air Quality3
NEW QUESTION # 20
A project that does not meet a prerequisite in one credit category
- A. may substitute a prerequisite from an alternative rating system
- B. does not qualify for certification
- C. forfeits all points in the same credit category
- D. must tile a CIR
Answer: B
Explanation:
Explanation
LEED prerequisites are the minimum requirements that a project must meet in order to be eligible for LEED certification. Prerequisites are mandatory for all projects and cannot be substituted or waived. If a project does not meet a prerequisite in one credit category, it does not qualify for certification, regardless of how many points it earns in other categories123.
A project that does not meet a prerequisite in one credit category does not forfeit all points in the same credit category, as points are awarded for meeting optional credits, not prerequisites. A project cannot file a CIR (Credit Interpretation Request) to seek clarification or exception for a prerequisite, as CIRs are only applicable for credits. A project cannot substitute a prerequisite from an alternative rating system, as prerequisites are specific to each rating system and reflect the minimum standards for that system
NEW QUESTION # 21
What is a reason to clearly identify the project boundary?
- A. To determine the total area of the project classified as a brownfield
- B. To define the building envelope
- C. To define the limits of site disturbance
- D. To give priority for certification to projects with a smaller footprint
Answer: C
Explanation:
Explanation
The project boundary is the area within which the project team has authority to implement the LEED requirements. It is important to clearly identify the project boundary to define the limits of site disturbance, which can affect the environmental performance of the project. For example, limiting site disturbance can help reduce soil erosion, protect natural habitats, and conserve water resources. The project boundary also determines the scope of the site assessment and the applicability of some credits. References: LEED v4 BD+C Reference Guide, Introduction, page 13

NEW QUESTION # 25
Which component directly reduces a building's Greenhouse Gas (GHG) emissions?
- A. Building Commissioning (Cx)
- B. Double-glazed windows
- C. Native plant landscaping
- D. High-efficiency HVAC
Answer: D
Explanation:
Explanation
A high-efficiency HVAC (Heating, Ventilation, and Air Conditioning) system can directly reduce a building's greenhouse gas emissions by using less energy than a standard system. Since most energy production involves the burning of fossil fuels, which releases greenhouse gases, using less energy results in fewer emissions. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
NEW QUESTION # 26
What is the percentage rule when making a decision on the rating system that is most appropriate to use for a project?
- A. 30/70 rule
- B. 60/40 rule
- C. 40/60 rule
- D. 50/50 rule
Answer: C
Explanation:
The percentage rule is a method to determine the most appropriate LEED rating system for a project when several rating systems may be applicable1. To use this rule, first assign a rating system to each square foot or square meter of the building, and then choose the most appropriate rating system based on the resulting percentages1. The entire gross floor area of a LEED project must be certified under a single rating system and is subject to all prerequisites and attempted credits in that rating system1. The percentage rule states that if one rating system covers more than 60% of the gross floor area, that rating system should be used1. If no rating system covers more than 60% of the gross floor area, but one covers more than 40%, then that rating system should be used1. If no rating system covers more than 40% of the gross floor area, then the project team can choose any applicable rating system1. Therefore, the answer is B. 40/60 rule.

- A. Helps project teams understand LEED system goals and determine what a LEED project should accomplish
- B. Determines the number of points needed in each category to achieve a certain certification level
- C. Determines the number of potential technical pathways accepted by LEED for each credit
- D. Describes the issues that LEED projects are not meant to address
Answer: A
Explanation:
Explanation
LEED impact categories are the environmental, social, and economic issues that LEED projects aim to address1. They provide an overview of the market transformation that technical requirements work to achieve, as well as a guide to where points should be assigned2. The categories focus on LEED's social, environmental, and economic goals, and they assess each strategy based on its ability to achieve those goals3.
NEW QUESTION # 28
Which of the following sites is most appropriate to encourage a walkable street design?
- A. A development that uses many culs-de-sac in the street design
- B. A project in an area designed with streets to facilitate increased speed limits
- C. A neighborhood that includes a diversity of use
- D. An area with a decreased building-height-to-street-width ratio
Answer: C
Explanation:
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.
