- B. Purchasing and demolishing a 100-year-old apartment building to build a new. energy-efficient building
- C. Locating a new building in a dense district with a diversity of uses and plentiful transit routes
- D. Designing a building envelope with the most advanced technology to maximize insulation values, regardless of what materials are used
Answer: A
Explanation:
Renovating an existing building using recycled and salvaged building materials is an example of a life-cycle approach to development or design. A life-cycle approach is an approach that considers the environmental impacts of a product or a project from cradle to grave, or from extraction of raw materials to disposal or reuse. Renovating an existing building using recycled and salvaged building materials reduces the environmental impacts associated with new construction, such as land use change, resource depletion, energy consumption, waste generation, and greenhouse gas emissions. The LEED Green Associate Candidate Handbook states that one of the intents of the Materials and Resources category is to "promote life-cycle assessment as a means of evaluating environmental impacts" [1, p. 15].

High reflectance roofing materials can help reduce heat gain and peak air temperatures by reflecting more sunlight away from the building, thereby reducing the amount of heat absorbed by the roof. This can lead to lower cooling loads and energy use for air conditioning. Reference: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
NEW QUESTION # 82
Which of the following actions Is a strategy to reduce construction waste?
- A. Develop a construction waste management policy
- B. Use materials with a high recycled content
- C. Hire a consultant to sort construction waste off site
- D. Perform a waste stream audit
Answer: B
Explanation:
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. References: LEED Green Associate Candidate Handbook, page 26; USGBC, [Materials and Resources], page 2.
NEW QUESTION # 83
When a developer builds a new shopping center in a rural area, one externality might be
- A. an increase in the fees for customer parking
- B. an increase in profits for the developer
- C. an increase in traffic on adjacent roads
- D. an increase in installation of rooftop solar
Answer: C
Explanation:
Explanation
An externality is a consequence of an economic activity that affects other parties who are not directly involved in the activity. Externalities can be positive or negative, depending on whether they create benefits or costs for others. When a developer builds a new shopping center in a rural area, one externality might be an increase in traffic on adjacent roads. This is a negative externality because it imposes costs on other road users who are not part of the development project, such as increased travel time, fuel consumption, air pollution, noise pollution, and accident risk13. References: LEED v4 Green Associate Candidate Handbook1, Investopedia's Externality
NEW QUESTION # 84
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. Project CIR
- C. Credit Submittal Form
- D. Scorecard
Answer: D
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.

As of 1996, the Montreal Protocol banned the production of what chemical compound known to have ozone-depleting potential?
- A. Hvdrofluorocarbons (HFCs)
- B. Hvdrochlorofluorocarbons (HCFCs)
- C. Hvdrofluorocarbons Phaseout Management Plan (HPMP)
- D. Chlorofluorocarbons (CFCs]
Answer: D
Explanation:
As of 1996, the Montreal Protocol banned the production of chlorofluorocarbons (CFCs), a chemical compound known to have ozone-depleting potential. CFCs are synthetic substances that were widely used as refrigerants, propellants, solvents, and foam-blowing agents. CFCs have high ozone depletion potential (ODP), which means they can destroy the ozone layer that protects the Earth from harmful ultraviolet radiation. 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. The Montreal Protocol banned the production of CFCs in 1996 for developed countries and in 2010 for developing countries1 .

NEW QUESTION # 89
Which of the following negative impacts on the environment are a result of waste being transported/diverted to landfills?
- A. Waste is incinerated and used to generate energy
- B. Solid waste produces methane and potent greenhouse gas
- C. Decreased post-consumer recycled content
- D. Increased pre-consumer recycled content
Answer: A
Explanation:
Explanation
Waste that is transported or diverted to landfills can have negative impacts on the environment, such as occupying valuable land, contaminating soil and water, and emitting harmful gases. One of the most significant impacts is the production of methane, a potent greenhouse gas that contributes to global warming and climate change. Methane is generated when organic waste decomposes anaerobically (without oxygen) in landfills. Methane has a global warming potential 28 times higher than carbon dioxide over a 100-year period12. References: LEED v4 Green Associate Candidate Handbook1, EPA's Landfill Methane Outreach Program2
