USGBC LEED-GA Online Practice Questions and Exam Preparation

USGBC LEED-GA Online Questions & Answers

• Question 91:

  What is the optimal method to divert solid waste from landfills?

  A. Recover
  B. Reduce
  C. Reuse
  D. Recycle
  B. Reduce

  ---

  According to the EPA and emphasized by LEED:

  "The preferred waste management strategies described by the U.S. Environmental Protection Agency (EPA)

  are source reduction, reuse, recycling and recovery."

  "Reduce" or "source reduction" is the top strategy for avoiding waste altogether.

• Question 92:

  In addition to the temperature and humidity, what is another factor to consider when implementing thermal comfort strategies?

  A. Daylight
  B. Acoustics
  C. Air movement
  D. Green cleaning
  C. Air movement

  ---

  Air movement is a factor that affects the thermal comfort of occupants, as it influences the heat exchange between the human body and the surrounding air1..Air movement can be controlled by mechanical systems, such as fans, or natural systems, such as operable windows..LEED v4 requires that at least 50% of individual occupant spaces have thermal comfort controls that allow occupants to adjust air movement in their local environment. .1.LEED (BD+C)- Indoor Environmental Quality Credit: Thermal comfort2.Get to Know LEED.: How to Provide Thermal Comfort in a LEED for Homes ....3.CI-v4.1 EQc5: Thermal comfort | LEEDuser.

• Question 93:

  Which of the following does LEED promote by encouraging compact development?

  A. Urban sprawl
  B. Walkability
  C. Historic preservation
  D. Development of new infrastructure
  B. Walkability

  ---

  One of the things that LEED promotes by encouraging compact development is walkability..Compact development is a form of urban planning that aims to reduce sprawland make more efficient use of land and resources by increasing density, diversity, and connectivity of land uses5. Compact development can enhance walkability by creating mixed-use neighborhoods that provide a variety of destinations within walking distance, such as shops, services, workplaces, schools, parks, and transit stops.

  Walkability can offer multiple benefits for the environment, health, economy, and social equity..For example, walkability can reduce greenhouse gas emissions and air pollution byreplacing car trips with walking or transit; improve physical and mental health by increasing physical activity and reducing stress; support local businesses and generate tax revenues by increasing foot traffic and property values; and foster social cohesion and civic engagement by creating vibrant public spaces and enhancing

  accessibility for all6..

• Question 94:

  Which location for a new building will have the greatest impact on lowering greenhouse gas emissions?

  A. An economic development district
  B. A brownfield location
  C. A previously developed site
  D. An urban center instead of the suburbs
  D. An urban center instead of the suburbs

  ---

  LEED promotes compact, transit-rich locations:

  "Locating a project in an area that supports walking, biking, and mass transit... will result in lower GHG

  emissions from reduced car travel."

  Urban centers offer the best access to alternative transport and reduce reliance on fossil fuels.

• Question 95:

  Which of the following promote the thermal comfort of occupants?

  A. Adjustable blinds and light shelves
  B. High cubicle partitions and large window-to-wall ratios
  C. Adjustable temperature with ventilation control
  D. Dimmable lighting and daylighting
  C. Adjustable temperature with ventilation control

  ---

  LEED Thermal Comfort credit requires:

  "Comfort Control ?defined as the ability to adjust air / radiant temperature, air velocity or humidity... Ensure 50% of individual occupant space have thermal comfort controls."

  Ventilation control combined with adjustable temperature directly supports occupant comfort as per ASHRAE 55-2010.

• Question 96:

  In addition to prohibiting smoking inside buildings, it is also important to prohibit smoking near:

  A. Covered parking spaces
  B. Landscaped areas
  C. Air exhausts
  D. Building entrances
  D. Building entrances

  ---

  As per the LEED prerequisite for Environmental Tobacco Smoke (ETS) Control:

  "Prohibit smoking in the building and on property within 25 feet from operable windows, entries and air

  intakes."

  Building entrances are particularly sensitive areas where smoke can enter the ventilation system.

• Question 97:

  Which of the following benefits could result from achieving LEED certification for a building?

  A. Preferred public parking
  B. Increased waste to landfills
  C. Qualification for tax rebates
  D. Dedicated public transportation infrastructure
  C. Qualification for tax rebates

  ---

  LEED certification can provide financial benefits for a building, such as qualification for tax rebates, zoning allowances, and other incentives from local and state governments. These incentives can help offset the initial costs of green building and encourage more projects to pursue LEED ..

• Question 98:

  Which strategy reduces transportation-related emissions for building occupants?

  A. Providing preferred parking for carpools
  B. Expanding single-occupancy parking
  C. Increasing parking fees only
  D. Adding more drive-through lanes
  A. Providing preferred parking for carpools

  ---

  Carpool incentives reduce single-occupancy vehicle use and support the LEED Transportation Demand Management credit.

• Question 99:

  Which strategy promotes sustainable purchasing during construction?

  A. Specify green electronic equipment
  B. Develop a construction purchasing policy
  C. Reduce regional materials expense by 10%
  D. Implement an erosion and sedimentation plan
  B. Develop a construction purchasing policy

  ---

  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..

• Question 100:

  The LEED credit weightings. in regard to the most important environmental impacts and human benefits, are based on impact categories defined and established by the

  A. U.S. Green Building Council (USGBC)
  B. U.S. Federal Government and Department of Energy (DOE)
  C. Sheet Metal-and Air Conditioning Contractors National Association (SMACNA)
  D. American Society Of Heating, Refrigeration and Air-conditioning Engineers (ASHRAE)
  A. U.S. Green Building Council (USGBC)

  ---

  The LEED credit weightings are based on the impact categories defined and established by the USGBC, which is the organization that developed and administers the LEED rating system. The impact categories are aligned with the USGBC's mission and vision of transforming the built environment to enhance environmental and human health. The impact categories are also informed by the Environmental Protection Agency's (EPA) Tools for the Reduction and Assessment of Chemical and Other Environmental Impacts (TRACI) methodology, which provides a framework for assessing environmental impacts across different categories..
