NEW QUESTION # 229
Which project approach helps identify synergies between building systems and reduce costly design changes later in the project?
- A. Integrative process
- B. Value engineering only during construction
- C. Final review after occupancy only
- D. Siloed decision-making
Answer: A
Explanation:
The integrative process is the correct answer because it brings project team members together early to identify synergies, trade-offs, and opportunities across building systems. In LEED, integrative planning helps teams evaluate energy, water, site, materials, indoor environmental quality, operations, and occupant needs before major design decisions are locked in. This approach can reduce change orders, avoid conflicts, improve system performance, and support cost-effective sustainability strategies. Value engineering only during construction often removes green features after design decisions have already been made. Siloed decision-making prevents coordination among disciplines and can create inefficiencies. A final review after occupancy is too late to influence most design choices. Early collaboration is essential for optimizing whole-building performance and achieving LEED goals.
NEW QUESTION # 230
Which of the following is an Environmental Concern when referring to Energy and Atmosphere?
- A. Ventilation levels
- B. Use of native species
- C. Occupant comfort
- D. Resource depletion
Answer: D
Explanation:
Explanation
Resource depletion is a major environmental concern related to energy use. The extraction and use of non-renewable energy resources (such as fossil fuels) can lead to their depletion over time. This is why strategies that reduce energy use or utilize renewable energy sources are important in green building practices. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
NEW QUESTION # 231
The cost of Commissioning (Cx) Is often repaid with
- A. advanced energy metering
- B. renewable power management
- C. enhanced refrigerant management
- D. recovered energy performance
Answer: D
Explanation:
Explanation
The cost of commissioning (Cx) is often repaid with recovered energy performance. Commissioning is a process of verifying and documenting that a building and its systems meet the design intent and the owner's project requirements. Commissioning can help improve the energy efficiency, indoor environmental quality, and occupant satisfaction of a building. According to a study by Lawrence Berkeley National Laboratory, commissioning can result in median energy savings of 13% for existing buildings and 16% for new construction, with payback times of 1.1 years and 4.2 years, respectively1. Therefore, commissioning can be a cost-effective investment that pays off with reduced energy consumption and costs over the life cycle of a building.

NEW QUESTION # 232
A site that has been graded is commonly defined as
- A. previously undeveloped
- B. a greenfield
- C. a brownfield
- D. previously developed
Answer: D
Explanation:
Explanation
According to the LEED v4 Glossary of Terms1, a site that has been graded is commonly defined as previously developed, which means "land that has been altered by paving, construction, and/or land use that would typically have required regulatory permitting to have been initiated (alterations may exist now or in the past)"1. A greenfield is "a site not previously developed or graded that could support open space, habitat, or agriculture"1. A brownfield is "a property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant"1. A previously undeveloped site is "a site that has never been built on or graded for development"2.
NEW QUESTION # 233
Which of the following concepts uses drought-tolerant native and adaptive plants to promote water conservation?
- A. Weather-based irrigation
- B. Xeriscaplng
- C. Bioswales
- D. Monoculture
Answer: B
Explanation:
Xeriscaping is a landscaping practice that uses drought-tolerant native and adaptive plants to reduce water use and maintenance. Xeriscaping also incorporates other strategies such as mulching, efficient irrigation, soil improvement, and appropriate design and zoning. By using xeriscaping, projects can conserve water, protect natural habitats, reduce stormwater runoffand pollution, and enhance the aesthetic and ecological value of the site. References: LEED v4 Reference Guide for Building Design and Construction, p. 123 1; [Xeriscape Colorado website]

NEW QUESTION # 235
The project team for a new office building would like to achieve Materials and Resources Credit Construction and Demolition Waste Management Which strategy contributes to achieving this goal?
- A. Purchasing Renewable Energy Certificates (RECs)
- B. Providing an off-site location for all waste and construction debris
- C. Providing an on-site location for all waste to be sorted
- D. Providing a centralized location in the building for recycling office products
Answer: C
NEW QUESTION # 236
Which process evaluates the environmental impact of a building project by considering factors from raw material extraction to disposal?
- A. Life-cycle assessment
- B. Life-cycle costing
- C. Sustainable Sites planning
- D. Environmental Product Declaration
Answer: A
Explanation:
Life-cycle assessment is the correct answer because it evaluates environmental impacts across a product's or project's life cycle. This includes raw material extraction, manufacturing, transportation, installation, use, maintenance, and end-of-life disposal or recovery. In LEED Materials and Resources, life-cycle thinking helps project teams reduce embodied environmental impacts and select materials or building systems with lower burdens. An Environmental Product Declaration may report life-cycle assessment results for a product, but it is not the general process named in the question. Sustainable Sites planning focuses on land, habitat, rainwater, heat island reduction, and site impacts. Life-cycle costing is different because it evaluates economic performance over time, including initial cost, operation, maintenance, replacement, and savings, rather than environmental impacts.
NEW QUESTION # 237
What is the term for collecting, reprocessing, marketing and using materials that are diverted or recovered from the solid waste stream?
- A. Recycling
- B. Chain -of-custody
- C. Building material reuse
- D. Salvaged materials
Answer: A
Explanation:
Recycling is the term for collecting, reprocessing, marketing and using materials that are diverted or recovered from the solid waste stream. Recycling is a process that transforms waste materials into new products that can be used for different purposes. Recycling reduces the amount of waste sent to landfills or incinerators, conserves natural resources, saves energy, and reduces greenhouse gas emissions. The LEED Green Associate Candidate Handbook states that one of the intents of the Materials and Resources category is to "reduce waste through recycling during construction and occupancy" [1, p. 15]. Reference: LEED Green Associate Candidate Handbook, [Recycling Basics | U.S. Environmental Protection Agency]
NEW QUESTION # 238
A salvaged wood door from another site qualifies under what Materials and Resources sustainable criteria?
- A. Certified wood
- B. Waste diversion
- C. Bio-based materials
- D. Materials reuse
Answer: D
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 # 239
In addition to the temperature and air movement, what is another factor to consider when implementing Thermal Comfort strategies?
- A. Humidity
- B. Combustion processes from vehicles
- C. Carbon dioxide concentrations
- D. Methane off-gassing
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. References: LEED Green Associate Candidate Handbook, page 29; USGBC, [Indoor Environmental Quality], page 2.
NEW QUESTION # 240
Which of the following describes the concept of electrification in the context of sustainable building practices?
- A. Increasing reliance on coal-fired power plants for electricity
- B. Implementing energy efficiency measures to reduce consumption
- C. Increasing natural gas use for space heating
- D. Replacing traditional gas appliances with electric counterparts
Answer: D
Explanation:
Electrification means shifting building systems and equipment from direct fossil fuel combustion to electric alternatives. Examples include replacing gas furnaces with electric heat pumps, gas water heaters with heat pump water heaters, and gas cooking equipment with electric or induction appliances. This supports decarbonization when paired with efficient design and cleaner grid or renewable electricity. Option A is incorrect because electrification is not intended to increase dependence on coal; its value improves as the electricity supply becomes cleaner. Option C is related to energy efficiency, but it does not define electrification. Efficiency reduces energy demand, while electrification changes the energy source. Option D is the opposite of electrification because it increases on-site fossil fuel combustion.
NEW QUESTION # 241
The LEED reviewer advised a project team that an inappropriate rating system was chosen for a newly constructed school in operation for one year and undergoing minor improvements. What should the project team have done differently to avoid this error?
- A. Select LEED for Schools New Construction and Major Renovations Rating System, as this project is classified as a school
- B. Select LEED for Existing Buildings: Operations and Maintenance Rating System, as the Operational and Maintenance phase has begun
- C. Green Building Council
- D. Allow the LEED Project Administrator sole responsibility to review the appropriate rating system for the project
- E. Review the appropriate rating system and determine the best adaptation to use with consultation from U.
Answer: B
Explanation:
The project team should have selected LEED for Existing Buildings: Operations and Maintenance Rating System, as the operational and maintenance phase has begun for a newly constructed school in operation for one year and undergoing minor improvements. The LEED rating systems are designed to address the specific needs and characteristics of different types of buildings and projects. The project team should choose the most appropriate rating system for their project based on the scope, scale, and goals of the project. The LEED for Existing Buildings: Operations and Maintenance Rating System is intended for buildings that are already in use and want to improve their performance and sustainability through best practices in operation, maintenance, renovation, and occupant engagement1 .

NEW QUESTION # 242
Volatile organic compounds (VOCs) negatively impact which of the following entities?
- A. Quality of indoor air
- B. Durability of a product
- C. Ability to recycle a product
- D. Quality of daylight
Answer: A
Explanation:
Explanation
Volatile organic compounds (VOCs) are compounds that have a high vapor pressure and low water solubility, and are emitted as gases from certain solids or liquids1. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects2. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors2. VOCs are emitted by a wide array of products, such as paints, solvents, cleaners, fuels, pesticides, building materials, office equipment, etc2. Breathing VOCs can irritate the eyes, nose and throat, can cause difficulty breathing and nausea, and can damage the central nervous system and other organs3. Some VOCs can cause cancer3. Therefore, VOCs negatively impact the quality of indoor air, which is option B.
NEW QUESTION # 243
Up lo how many maximum points can a project earn under the Regional Priority credit?
- A. Two
- B. Three
- C. Four
- D. One
Answer: C
Explanation:
A project can earn up to four maximum points under the Regional Priority credit. The Regional Priority credit is a bonus credit that rewards projects for addressing environmental issues that are of regional importance. The USGBC regional councils and chapters have identified six environmental issues for each zip code in the United States, and projects can earn one point for each issue they address, up to a maximum of four points. The other options are not correct. One, two, or three points are possible, but not the maximum number of points under the Regional Priority credit. Reference: LEED Green Associate Candidate Handbook, page 30; USGBC, [Regional Priority], page 1.
NEW QUESTION # 244
Which of the following Is a strategy for improving Indoor Environmental Quality during construction?
- A. Collect construction debris in the mechanical room
- B. Run permanently installed HVAC with final filtration media
- C. Cover duct work with plastic
- D. Store absorptive-finish materials directly on slab
Answer: C
Explanation:
Explanation
Covering duct work with plastic is a strategy for improving indoor environmental quality during construction.
Covering duct work with plastic prevents dust, debris, and contaminants from entering the ducts and affecting the air quality of the building. This also reduces the need for cleaning and maintenance of the ducts after construction. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving indoor environmental quality is to "protect ducts during construction by sealing or covering with plastic" [1, p.
16]. References: LEED Green Associate Candidate Handbook, [Indoor Air Quality During Construction | U.S.
Environmental Protection Agency]
NEW QUESTION # 245
Which strategy promotes sustainable purchasing during construction?
- A. Implement an erosion and sedimentation plan
- B. Reduce regional materials expense by 10%
- C. Develop a construction purchasing policy
- D. Specify green electronic equipment
Answer: C
Explanation:
Explanation
Developing a construction purchasing policy is a strategy that promotes sustainable purchasing during construction. A construction purchasing policy is a document that outlines the criteria and requirements for selecting materials, products, and services that have lower environmental impacts and support human health during construction. A construction purchasing policy can address issues such as recycled content, regional materials, certified wood, low-emitting materials, rapidly renewable materials, durability, life cycle assessment, waste reduction, and indoor air quality. The other options are not strategies that promote sustainable purchasing during construction. Specifying green electronic equipment is relevant for operations purchasing, not construction purchasing. Reducing regional materials expense by 10% does not necessarily imply sustainable purchasing, as regional materials may have higher or lower environmental impacts depending on their source and transportation methods. Implementing an erosion and sedimentation plan is a strategy that protects water quality during construction, but does not address sustainable purchasing. References: LEED Green Associate Candidate Handbook, page 24; USGBC, [Guide to LEED Certification: Commercial], page 12.
