- A. Combustion processes from vehicles
- B. Carbon dioxide concentrations
- C. Methane off-gassing
- D. Humidity
Answer: D
Explanation:
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.
Methaneoff-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.

- A. Chlorofluorocarbons (CFCs)
- B. Hydrochlorofluorocarbons {HCFCs}
- C. Hydrofluorocarbons (HFCs)
- D. Ammonia (NH3)
Answer: A
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.

NEW QUESTION # 151
If a project has achieved 53 points and six of eight prerequisites, for what level of certification does the project qualify?
- A. Silver
- B. Gold
- C. Certified
- D. None
Answer: D
Explanation:
To qualify for any level of LEED certification, a project must meet all the prerequisites and achieve a minimum number of points based on the rating system and the certification level1. The prerequisites are mandatory requirements that must be met before a project can earn any points2. The points are awarded for achieving optional credits that demonstrate environmental performance and innovation2. The LEED rating system consists of five broad categories: Building Design and Construction (BD+C), Interior Design and Construction (ID+C), Building Operations and Maintenance (O+M), Neighborhood Development (ND), and Homes3. Each category has different adaptations for specific project types and scopes, such as Schools, Retail, Hospitality, Data Centers, Warehouses and Distribution Centers, Healthcare, etc3. Each adaptation has a different number of prerequisites and credits, and a different point scale for each certification level4. The certification levels are: Certified, Silver, Gold, and Platinum1. The minimum points required for each level vary depending on the rating system and the adaptation, but generally range from 40 to 80 points1.
In this question, the project has achieved 53 points and six of eight prerequisites. This means that the project has failed to meet two prerequisites, which are mandatory requirements. Therefore, the project does not qualify for any level of LEED certification, regardless of the rating system or the adaptation. The answer is A. None.

NEW QUESTION # 153
Which of the following Is a source of green power?
- A. Nuclear fission
- B. Wind turbine
- C. Clean coal
- D. Natural gas captured by hydraulic fracturing
Answer: B
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.
