Which Is a component of a construction waste management plan?
- A. Quantity of waste generated from excavated soil
- B. List of materials to be diverted from disposal
- C. Distance of the recycling facility from the project site
- D. Projected cost savings from diverting waste
Answer: B
Explanation:
A list of materials to be diverted from disposal is a component of a construction waste management plan. A construction waste management plan is a document that outlines the goals, procedures, and responsibilities for diverting construction and demolition waste from landfills or incinerators. A list of materials to be diverted from disposal identifies the types and quantities of materials that can be recycled, reused, salvaged, or donated, as well as the destinations and methods for diversion. The other options are not components of a construction waste management plan. Projected cost savings from diverting waste is a potential benefit of implementing a construction waste management plan, but it is not a required component. Quantity of waste generated from excavated soil is a factor that affects the construction waste generation rate, but it is not a component of a construction waste management plan. Distance of the recycling facility from the project site is a factor that affects the transportation emissions and costs associated with diverting waste, but it is not a component of a construction waste management plan.

- 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. Greenfield site in a low-density area with some transportation connectivity
- D. Infill site within an existing neighborhood with substantial transit connectivity
Answer: D
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].

NEW QUESTION # 54
Which of the following does LEED promote by encouraging compact development?
- A. Development of new infrastructure
- B. Walkability
- C. Urban sprawl
- D. Historic preservation
Answer: B
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 # 55
Which of the following Is a source of green power?
- A. Clean coal
- B. Natural gas captured by hydraulic fracturing
- C. Nuclear fission
- D. Wind turbine
Answer: D
Explanation:
A wind turbine is a source of green power, which is electricity generated from renewable sources that have low or zero greenhouse gas emissions. A wind turbine converts the kinetic energy of the wind into mechanical power, which can then be used to generate electricity. Wind power is a clean, abundant, and sustainable form of energy that does not produce air pollution or contribute to climate change. According to the U.S. Department of Energy, wind power accounted for about 8.4% of the total U.S. electricity generation in 2020. The other options are not sources of green power, as they either rely on fossil fuels or nuclear energy, which have significant environmental and social impacts. Clean coal is a term used to describe technologies that aim to reduce the emissions and waste from burning coal, but it is still a carbon-intensive and polluting source of energy. Nuclear fission is a process that splits atoms to release energy, but it also produces radioactive waste that poses long-term health and safety risks. Natural gas captured by hydraulic fracturing, or fracking, is a process that injects water, chemicals, and sand into underground rock formations to release natural gas, but it also causes water contamination, air pollution, and seismic activity.

NEW QUESTION # 61
The Montreal Protocol banned the production of
- A. CFCs
- B. freon
- C. ammonia
- D. HCFCs
Answer: A
Explanation:
Explanation
The Montreal Protocol is an international treaty that aims to protect the ozone layer by phasing out the production and consumption of ozone-depleting substances (ODS). ODS are chemicals that contain chlorine or bromine, which can destroy the ozone molecules in the stratosphere. CFCs, or chlorofluorocarbons, are a group of ODS that were widely used in refrigeration, air conditioning, aerosols, and solvents. The Montreal Protocol banned the production of CFCs in 201012. Freon is a trade name for some CFCs and HCFCs, or hydrochlorofluorocarbons, which are also ODS but less harmful than CFCs. The Montreal Protocol also controls the production of HCFCs, which are being phased out gradually12. Ammonia is not an ODS and is not regulated by the Montreal Protocol1.
