NEW QUESTION # 129
In a large site that has a short, intense rainy season and a long, dry season, what component of a collected rainwater irrigation system is most likely to make it cost prohibitive over a conventional system?
- A. Landscaping plant selection
- B. Irrigation piping systems
- C. Rainwater storage cisterns
- D. Irrigation control systems
Answer: C
Explanation:
Explanation
Rainwater storage cisterns are components of a collected rainwater irrigation system that are most likely to make it cost prohibitive over a conventional system in a large site that has a short, intense rainy season and a long, dry season. A collected rainwater irrigation system is a system that collects, stores, and distributes rainwater for irrigation purposes. Rainwater storage cisterns are containers that store the collected rainwater until it is needed for irrigation. In a large site that has a short, intense rainy season and a long, dry season, the rainwater storage cisterns would need to be very large and durable to capture and store enough rainwater for the dry season. This would increase the initial cost and maintenance cost of the system compared to a conventional system that uses potable water or groundwater for irrigation1 .

NEW QUESTION # 131
According to LEED. which of the following should be considered when locating a site for a project?
- A. Economic stability
- B. Political landscape
- C. Revenue generating possibilities
- D. Infrastructure context
Answer: D
Explanation:
According to LEED, one of the factors that should be considered when locating a site for a project is the infrastructure context. The infrastructure context refers to the existing physical systems that support a site, such as roads, utilities, transit networks, water supply, wastewater treatment, stormwater management, and waste disposal. Choosing a site that has access to adequate infrastructure can reduce the environmental impacts of developing new infrastructure, such as land disturbance, resource consumption, energy use, emissions, and pollution. The LEED Green Associate Candidate Handbook states that one of the intents of the Location and Transportation category is to "reduce environmental harm from transportation infrastructure" [1, p. 12]. Reference: LEED Green Associate Candidate Handbook, [Location and Transportation | U.S. Green Building Council]

CFCs are known to deplete the ozone layer when released into the atmosphere, and their use has been phased out in many countries under the Montreal Protocol. Reference: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
NEW QUESTION # 133
Which class of refrigerants contributes the most to ozone depletion potential (ODP)?
- A. Hydrochlorofluorocarbons {HCFCs}
- B. Hydrofluorocarbons (HFCs)
- C. Chlorofluorocarbons (CFCs)
- D. Ammonia (NH3)
Answer: C
Explanation:
Explanation
Chlorofluorocarbons (CFCs) are the class of refrigerants that contribute the most to ozone depletion potential (ODP). Ozone depletion potential is a measure of how much a substance can damage the ozone layer in the stratosphere, which protects life on Earth from harmful ultraviolet radiation. CFCs are synthetic chemicals that contain chlorine, fluorine, and carbon atoms. They were widely used as refrigerants, aerosol propellants, solvents, and foam blowing agents until they were phased out by the Montreal Protocol due to their high ODP.
The LEED Green Associate Candidate Handbook states that one of the strategies for achieving energy and atmosphere efficiency is to "eliminate chlorofluorocarbons (CFCs) in new building HVAC&R systems" [1, p.
15]. References: LEED Green Associate Candidate Handbook, [Ozone Depletion Potential | U.S.
