• A. To give priority for certification to projects with a smaller footprint
• B. To define the building envelope
• C. To define the limits of site disturbance
• D. To determine the total area of the project classified as a brownfield

Answer: C

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. Reference: LEED v4 BD+C Reference Guide, Introduction, page 13

NEW QUESTION # 35
Which of the following is a cause of surface water degradation?

• A. Expansion of outdoor filtration systems
• B. Expansion of impervious surfaces
• C. Rainwater harvesting
• D. Expansion of pervious surfaces

Answer: B

Explanation:
Explanation
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.

NEW QUESTION # 36
An owner is looking to update the interior materials of the office while promoting a healthier indoor work environment using LEED strategies. During the materials specification, which of the following strategies can the owner take in order to achieve this goal?

• A. Specify low-cost materials
• B. Specify salvaged materials
• C. Specify low-emitting materials
• D. Specify high solar reflectance materials

Answer: C

Explanation:
Explanation
An owner who wants to update the interior materials of the office while promoting a healthier indoor work environment using LEED strategies can specify low-emitting materials as one of the strategies to achieve this goal. Low-emitting materials are materials that have low or no emissions of volatile organic compounds (VOCs) or other pollutants into the indoor air. VOCs are organic chemicals that can evaporate or vaporize at room temperature and can adverselyaffect the indoor air quality (IAQ) of a building and the health, comfort, and productivity of the occupants. Some sources of VOCs in buildings are paints, coatings, adhesives, sealants, flooring, furniture, and cleaning products. Specifying low-emitting materials can reduce the exposure and risk of VOCs for the occupants and improve IAQ12. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide2

NEW QUESTION # 40
Which of the following does LEED promote by encouraging compact development?

• A. Walkability
• B. Development of new infrastructure
• C. Historic preservation
• D. Urban sprawl

Answer: A

Explanation:
One of the things that LEED promotes by encouraging compact development is walkability. Compact development is a form of urban planning that aims to reduce sprawl and make more efficient use of land and resources by increasing density, diversity, and connectivity of land uses5. Compact development can enhance walkability by creating mixed-use neighborhoods that provide a variety of destinations within walking distance, such as shops, services, workplaces, schools, parks, and transit stops. Walkability can offer multiple benefits for the environment, health, economy, and social equity. For example, walkability can reduce greenhouse gas emissions and air pollution by replacing car trips with walking or transit; improve physical and mental health by increasing physical activity and reducing stress; support local businesses and generate tax revenues by increasing foot traffic and property values; and foster social cohesion and civic engagement by creating vibrant public spaces and enhancing accessibility for all6. Reference: Compact urban development6; LEED v4 BD+C Reference Guide, Location and Transportation, page 15

NEW QUESTION # 41
Which of the following sites would maximize LEED points under Location and Transportation?

• A. Infill site on the outskirts of a city with some transportation connectivity
• B. Greenfield site in an urban area with substantial transit connectivity
• C. Infill site within an existing neighborhood with substantial transit connectivity
• D. Greenfield site in a low-density area with some transportation connectivity

Answer: C

Explanation:
Explanation
An infill site within an existing neighborhood with substantial transit connectivity would maximize LEED points under Location and Transportation. An infill site is a site that has been previously developed or graded and is surrounded by existing development. An existing neighborhood is a geographic area with a variety of land uses, such as residential, commercial, educational, or recreational. Substantial transit connectivity means that the site has access to multiple modes of public transportation, such as buses, trains, light rail, or bicycles.
The LEED Green Associate Candidate Handbook states that one of the intents of the Location and Transportation category is to "encourage development within existing communities and public transit infrastructure" [1, p. 12].

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 # 45
What is the percentage rule when making a decision on the rating system that is most appropriate to use for a project?

• A. 40/60 rule
• B. 30/70 rule
• C. 60/40 rule
• D. 50/50 rule

Answer: A

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.
