USGBC LEED-GA Online Questions & Answers

• Question 171:

  A firm has been hired to renovate an existing office building and wants to increase the number of points the project receives for Location and Transportation credits. What strategy might the firm recommend?

  A. Shade the large open parking area with a solar-paneled canopy
  B. Include subsidies for carpools
  C. Replace traditional paving on the parking lot with pervious surfacing
  D. Reduce the building's footprint on the site
  B. Include subsidies for carpools

  ---

  Including subsidies for carpools is a strategy that can increase the number of points the project receives for Location and Transportation credits..This is because it reduces the demand for single-occupancy vehicle trips and parking spaces, which in turn reduces greenhouse gas emissions, traffic congestion, and land consumption12..The project can earn up to 15 points for the Transportation Demand Management credit by providing various incentives and programs to encourage alternative modes of transportation, such as carpooling, public transit, biking, or walking12.

• Question 172:

  What are the values and benefits of building green?

  A. It will encourage others to build green
  B. It will lower the price for green materials
  C. It will enhance the health of the building occupants
  D. It is not as expensive to build as conventional design buildings
  C. It will enhance the health of the building occupants

  ---

  One of the values and benefits of building green is that it will enhance the health of the building occupants. Building green is a process that incorporates environmental considerations into every stage of a building's life cycle, from design to construction to operation to end-of-life. Building green can improve the indoor environmental quality (IEQ) of a building, which is the physical and psychological conditions of the indoor spaces that affect the health, comfort, and productivity of the occupants..Building green can enhance IEQ by using low-emitting materials, providing adequate ventilation, controlling temperature and humidity, optimizing daylighting and lighting quality, reducing noise levels, and promoting occupant well-being..

• Question 173:

  Which of the following organizations' standards are referenced by the LEED rating systems?

  A. American Institute of Architects (AIA)
  B. Meeting Professionals International (MPI)
  C. National Fire Protection Association (NFPA)
  D. International Organization for Standardization (ISO)
  C. National Fire Protection Association (NFPA)

  ---

  The LEED rating systems reference the standards of various organizations that are relevant to green building design, construction, and operation. The National Fire Protection Association (NFPA) is one of these organizations, and its standards cover topics such as fire safety, electrical safety, emergency power systems, and fire suppression systems. The LEED rating systems reference the NFPA standards in several credits and prerequisites, such as Minimum Energy Performance, Minimum Indoor Air Quality Performance, and Environmental Tobacco Smoke Control.

• Question 174:

  Which of the following strategies, when designed together, can save energy and improve occupant experience?

  A. Daylighting and natural ventilation
  B. Thermal comfort and water meters
  C. Energy metering and thermal comfort
  D. Ventilation and carbon monoxide monitoring
  A. Daylighting and natural ventilation

  ---

  Daylighting and natural ventilation are strategies that can be used together to save energy and improve occupant experience in a building. Daylighting uses natural light to illuminate the interior spaces of a building, reducing the need for artificial lighting and improving the visual comfort and well-being of the occupants..Natural ventilation uses outdoor air to provide freshair and cooling to a building, reducing the need for mechanical ventilation and air conditioning and improving the indoor air quality and thermal comfort of the occupants1...

• Question 175:

  An integrative process involves stakeholders identifying overlapping relationships, services and redundancies among systems. What does this result in?

  A. Reduced performance and reduced costs
  B. Increased performance and reduced costs
  C. Reduced performance and increased costs
  D. Increased performance and increased costs
  B. Increased performance and reduced costs

  ---

  An integrative process is a collaborative approach that involves all project stakeholders in the design and decision-making process from the beginning to the end of a project. It aims to optimize the performance, environmental, social, and economic outcomes of a project by considering the interrelationships and synergies between various building and site systems. By identifying overlapping relationships, services and redundancies among systems, an integrative process can result in increased performance and reduced costs, as it can create more efficient, effective, and innovative solutions that meet the project goals and requirements. For example, an integrative process can help to reduce the energy demand of a building by integrating passive design strategies, such as building orientation, envelope design, daylighting, natural ventilation, and shading, which can also improve the indoor environmental quality and occupant comfort..An integrative process can also help to reduce the material and water consumption of a project by reusing existing resources, selecting durable and low-impact materials, and implementing water-efficient fixtures and systems, which can also reduce the waste generation and environmental impact of the project

• Question 176:

  Which rating system is appropriate for a project with routine operations and little new construction?

  A. LEED O+M
  B. LEED BD+C
  C. LEED ID+C
  D. LEED ND
  A. LEED O+M

  ---

  Operations and Maintenance applies to existing buildings undergoing performance improvement rather than major construction.

• Question 177:

  Which of the following facilitates the recharging of aquifers?

  A. Asphalt road
  B. Pervious paving
  C. Impervious paving
  D. Concrete parking lot
  B. Pervious paving

  ---

  Pervious paving, also known as permeable paving, allows water to pass through it, facilitating the recharging of aquifers. This type of paving reduces runoff by allowing water to soak into the ground, which can help replenish groundwater supplies and reduce the impact on nearby water bodies..

• Question 178:

  What is the unit of measure for water closets?

  A. Gallons (Liters) per flush
  B. Gallons (Liters) per person
  C. Average usage per hour
  D. Usage per full time employee
  A. Gallons (Liters) per flush

  ---

  Water closets, also known as toilets, are fixtures that use water to flush human waste into a sewer or septic system. The unit of measure for water closets is gallons (liters) per flush, which indicates the amount of water used for each flushing cycle. The water efficiency of water closets can vary depending on the design, technology, and regulation of the fixture..The LEED rating system encourages the use of water-efficient fixtures that reduce water consumption and wastewater generation..

• Question 179:

  The Increase in air temperature in a developed area resulting from the dark surfaces of roadways, parking lots, and tarred rooftops is known as

  A. emissivity
  B. global warming
  C. greenhouse gas
  D. heat island effect
  D. heat island effect

  ---

  The increase in air temperature in a developed area resulting from the dark surfaces of roadways, parking lots, and tarred rooftops is known as heat island effect. Heat island effect is a phenomenon whereby urban areas experience higher temperatures than rural areas due to the absorption and re-emission of solar heat by man-made surfaces. Heat island effect can have negative impacts on human health, energy consumption, air quality, and climate change..Some strategies to reduce heat island effect include increasing vegetation cover, using reflective or green roofs, using cool or permeable pavements, and enhancing natural ventilation.

• Question 180:

  Which of the following is a tradable commodity representing proof that a unit of electricity was generated from a renewable source?

  A. Tradable Energy Credit (TEC)
  B. Renewable Wind Certificate
  C. Renewable Energy Certificate
  D. Certificate for Innovative Renewables
  C. Renewable Energy Certificate

  ---

  A Renewable Energy Certificate (REC) is a tradable commodity that represents proof that one unit of electricity was generated from a renewable energy source. RECs are used to track and trade renewable energy in the open market, providing an economic incentive for renewable energy generation..
