USGBC LEED-GA Online Questions & Answers

• Question 221:

  What is a characteristic of a brownfield site?

  A. It is a pristine ecological habitat
  B. It is contaminated or potentially contaminated land
  C. It is located in an agricultural buffer zone
  D. It is a newly cleared forested site
  B. It is contaminated or potentially contaminated land

  ---

  Brownfields are previously developed sites with contamination risk and redevelopment supports sustainable land reuse.

• Question 222:

  Which refrigerant type has the highest ozone depletion potential?

  A. CFCs
  B. HFCs
  C. HCFC alternatives
  D. Natural refrigerants
  A. CFCs

  ---

  Chlorofluorocarbons (CFCs) have extremely high ODP and are prohibited under LEED EA prerequisites.

• Question 223:

  Which strategy is an example of permanent entryway systems used to reduce dust, dirt and contaminants brought into a facility?

  A. Providing sensors at all entrances
  B. Conducting a thermal comfort survey
  C. Installing outdoor air monitoring equipment
  D. Placing grilles, grates or mats at all major entrances
  D. Placing grilles, grates or mats at all major entrances

  ---

  Placing grilles, grates or mats at all major entrances is an example of permanent entryway systems used to reduce dust, dirt and contaminants brought into a facility. Permanent entryway systems are designed to capture dirt and particulates from people's shoes and prevent them from entering the indoor environment. This improves the indoor air quality and reduces the need for cleaning and maintenance. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving indoor

  environmental quality is to "use permanent entryway systems (grilles, grates, mats) to reduce particulate matter being brought into buildings at regular entryways" [1, p. 16]..

• Question 224:

  The maximum number of points that can be achieved under the Energy and Atmosphere category for Building Design and Construction: New Construction and Major Renovation is:

  A. 33
  B. 35
  C. 30
  D. 31
  A. 33

  ---

  According to the LeadingGreen LEED GA Study Guide:

  "In LEED v4 for BD+C: New Construction, the Energy and Atmosphere category offers a maximum of 33 points."

  These points are awarded across various credits like Optimize Energy Performance, Demand Response, and Renewable Energy.

• Question 225:

  In the commercial LEED rating systems, which point range will achieve the Silver level of certification?

  A. 30-39 points
  B. 40-49 points
  C. 50-59 points
  D. 60-69 points
  B. 40-49 points

  ---

  In the commercial LEED rating systems, achieving 40-49 points will result in Silver level certification. The points are awarded based on how well the project meets various sustainability criteria set out in the LEED rating system..

• Question 226:

  All LEED rating systems include:

  A. 90 base points, plus four Innovation points and six Regional Priority points for a total of 100 points
  B. 110 base points, plus five Innovation points and two Regional Priority points for a total of 117 points
  C. 100 base points, plus six Innovation points and four Regional Priority points for a total of 110 points
  D. 110 base points, plus six Innovation points and four Regional Priority points for a total of 120 points
  C. 100 base points, plus six Innovation points and four Regional Priority points for a total of 110 points

  ---

  LEED rating systems are designed with 100 base points for core credits, six bonus points for Innovation, and four bonus points for Regional Priority credits. This structure allows projects to achieve a total of 110 points, reflecting LEED's flexibility and comprehensive approach.

• Question 227:

  Which of the following principles is a part of the integrated process?

  A. Cradle-to-cradle
  B. Systems thinking
  C. Project scheduling
  D. Building information modeling
  B. Systems thinking

  ---

  Systems thinking is a principle that is part of the integrated process, which is a collaborative and holistic approach to green building design, construction, and operation. Systems thinking involves understanding the interrelationships and interactions among the various components of a system, such as the building, its occupants, its site, its climate, and its energy sources..Systems thinking helps to identify synergies, optimize performance, avoid unintendedconsequences, and create multiple benefits for the project..

• Question 228:

  The amount of landfill-destined waste generated during project construction can be reduced by requiring the general contractor to

  A. burn paper and cardboard materials on-site
  B. use contractor vehicles to disperse waste materials to multiple disposal sites within the project region
  C. follow requirements for using dimensional construction materials, prefabrication or material efficient framing
  D. take advantage of municipal waste pick-up to reduce the weight of the project's construction material scraps
  C. follow requirements for using dimensional construction materials, prefabrication or material efficient framing

  ---

  The amount of landfill-destined waste generated during project construction can be reduced by requiring the general contractor to follow requirements for using dimensional construction materials, prefabrication or material efficient framing. These methods reduce the amount of material waste by minimizing cutting, fitting, and trimming on site, and by using standardized or modular components that can be easily reused or recycled. The LEED Green Associate Candidate Handbook states that one of the

  strategies for achieving materials and resources efficiency is to "reduce construction waste through efficient framing techniques" [1, p. 15]..

• Question 229:

  Which of the following materials meets responsible sourcing criteria?

  A. FSC-certified wood
  B. Virgin plastic
  C. Polyurethane foam
  D. Aluminum with no supply chain data
  A. FSC-certified wood

  ---

  FSC certification ensures wood comes from responsibly managed forests, qualifying under MR: Sourcing of Raw Materials.

• Question 230:

  Relating to water efficiency in LEED. gallons per minute or liters per minute refers to the amount of

  A. stormwater runoff
  B. captured rainwater
  C. water used by flow fixtures
  D. water used by flush fixtures
  C. water used by flow fixtures

  ---

  Gallons per minute or liters per minute refers to the amount of water used by flow fixtures in LEED. Flow fixtures are fixtures that deliver a constant stream of water, such as faucets, showerheads, or hose bibs. The flow rate of these fixtures is measured in gallons per minute (gpm) or liters per minute (L/min), which indicates how much water flows through them in a given time period. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving water efficiency is to "use low-

  flow faucets and showerheads (maximum 2.5 gpm at 80 psi)" [1, p. 14]..
