NEW QUESTION # 12
In addition to the temperature and air movement, what is another factor to consider when implementing Thermal Comfort strategies?
- A. Humidity
- B. Methane off-gassing
- C. Combustion processes from vehicles
- D. Carbon dioxide concentrations
Answer: A
Explanation:
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.

NEW QUESTION # 13
A salvaged wood door from another site qualifies under what Materials and Resources sustainable criteria?
- A. Materials reuse
- B. Waste diversion
- C. Certified wood
- D. Bio-based materials
Answer: A
Explanation:
A salvaged wood door from another site qualifies under the Materials and Resources sustainable criteria of materials reuse. Materials reuse is the practice of using existing materials or products for new purposes without altering their form or composition. Materials reuse reduces the demand for virgin materials, saves energy and resources, and prevents waste generation. The other options are not applicable to a salvaged wood door from another site. Certified wood is wood that has been harvested from forests that are managed in an environmentally responsible, socially beneficial, and economically viable manner according to the standards of an accredited certification system such as the Forest Stewardship Council (FSC). Bio-based materials are materials that are derived from plants or animals, such as bamboo, cork, wool, or cotton. Waste diversion is the practice of diverting waste from landfills or incinerators by recycling, reusing, salvaging, or donating materials. Reference: LEED Green Associate Candidate Handbook, page 28; USGBC, [Materials and Resources], page 4.
NEW QUESTION # 14
Which is an example of a low-cost Water Efficiency strategy?
- A. Use only compostable toilets throughout the facility
- B. Incorporate an on-site blackwater treatment system
- C. Install new flush valves or flow restrictors
- D. Install subsurface cisterns to collect stormwater
Answer: C
Explanation:
Installing new flush valves or flow restrictors is a low-cost strategy to improve water efficiency. These devices reduce the amount of water used in each flush or flow, leading to significant water savings over time. Other strategies like installing subsurface cisterns to collect stormwater, using only compostable toilets throughout the facility, or incorporating an on-site blackwater treatment system can also improve water efficiency, but they typically involve higher upfront costs.

NEW QUESTION # 15
Which of the following methods provides maximum water efficiency for a building irrigation system?
- A. Flow irrigation system
- B. Drip irrigation system
- C. Overhead spray sprinklers
- D. Revolving circular sprinklers
Answer: B
Explanation:
A drip irrigation system provides maximum water efficiency for a building irrigation system. A drip irrigation system delivers water directly to the root zone of plants, minimizing evaporation, runoff, and overspray. This reduces water consumption and prevents water pollution from fertilizers and pesticides. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving water efficiency in landscaping is to "use efficient irrigation systems, such as drip irrigation" [1, p. 14]. Reference: LEED Green Associate Candidate Handbook, [Drip Irrigation | U.S. Department of Agriculture]
NEW QUESTION # 16
Which type of site Is appropriate for development of LEED projects?
- A. Undeveloped
- B. Brownfield
- C. Floodplain
- D. Greenfield
Answer: B
Explanation:
A brownfield site is appropriate for development of LEED projects because it is a site that has been previously used for industrial or commercial purposes and may be contaminated by pollutants or hazardous substances. Developing a brownfield site can help reduce environmental impacts, such as soil erosion, habitat loss, and water consumption, by reusing existing infrastructure and restoring degraded land. LEED projects can earn credits for developing on brownfield sites under the Sustainable Sites category. Reference: LEED v4 BD+C Reference Guide, Sustainable Sites, page 35; Best Management Practice #14: Alternative Water Sources1
NEW QUESTION # 17
Which of the following does LEED promote by encouraging compact development?
- A. Urban sprawl
- B. Historic preservation
- C. Walkability
- D. Development of new infrastructure
Answer: C
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 # 18
Which of the following strategies encourages a building's users to use alternative transportation?
- A. Provide bicycle storage and shower facilities
- B. Locate building in a rural area
- C. Locate building near restaurants and theaters
- D. Provide preferred parking for business owners
Answer: A
NEW QUESTION # 19
Which of the following actions Is a strategy to reduce construction waste?
- A. Develop a construction waste management policy
- B. Hire a consultant to sort construction waste off site
- C. Perform a waste stream audit
- D. Use materials with a high recycled content
Answer: D
Explanation:
Using materials with a high recycled content is a strategy to reduce construction waste. Recycled content materials are made from pre-consumer or post-consumer waste that has been diverted from landfills or incinerators and reprocessed into new materials. Using recycled content materials reduces the demand for virgin materials, saves energy and resources, and prevents waste generation. The other options are not strategies to reduce construction waste. Performing a waste stream audit is a strategy to measure and analyze the types and quantities of waste generated by a building or project. Developing a construction waste management policy is a strategy to establish goals and procedures for diverting construction waste from landfills or incinerators. Hiring a consultant to sort construction waste off site is a strategy to outsource the responsibility of separating recyclable or reusable materials from construction waste, but it does not necessarily reduce the amount of waste generated. Reference: LEED Green Associate Candidate Handbook, page 26; USGBC, [Materials and Resources], page 2.
