USGBC LEED-GA Online Questions & Answers

• Question 321:

  Which LEED adaptation includes the ability to reduce point thresholds for LEED certification levels based on building size?

  A. LEED Interior Design and Construction: Retail
  B. LEED Neighborhood Development: Built Project
  C. LEED Building Design and Construction: Homes
  D. LEED Building Design and Construction: Schools
  C. LEED Building Design and Construction: Homes

  ---

  LEED Building Design and Construction: Homes is the rating system that applies to single-family homes, low-rise multi-family homes, and mid-rise multi-family homes1..It includes the ability to reduce point thresholds for LEED certification levels based on building size, as smaller homes tend to have lower environmental impacts than larger homes2..The point thresholds are determined by the size of the house compared to the number of bedrooms1. .2.LEED v4: Building Design + Construction Guide, Homes, p..171.The LEED rating system - Ecohome.

• Question 322:

  Which of the following contribute to the triple bottom line?

  A. Global security
  B. Social responsibility
  C. Project balance sheet
  D. Green metrics and verification
  B. Social responsibility

  ---

  Social responsibility is one of the factors that contribute to the triple bottom line. The triple bottom line is a framework that measures the performance of an organization or a project based on three dimensions: environmental, social, and economic. Social responsibility refers to the ethical obligation of an organization or a project to consider the impacts of its decisions and actions on society and stakeholders, such as employees, customers, communities, and future generations. The other options are not

  factors that contribute to the triple bottom line. Global security is a broad concept that encompasses various aspects of international relations, such as peace, human rights, justice, and cooperation. Project balance sheet is a financial statement that summarizes the assets, liabilities, and equity of a project at a given point in time. Green metrics and verification are tools and methods that quantify and validate the environmental performance of a project or a product..

• Question 323:

  Which of the following has the highest energy consumption in a typical U.S. office building?

  A. Lighting
  B. Cooling
  C. Space Heating
  D. Water Heating
  C. Space Heating

  ---

  According to the U.S. Energy Information Administration, space heating accounted for about 32% of energy use for all U.S..commercial buildings in 2018, followed by ventilation and lighting, each at about 10%1. Space heating is the largest single energy end use in U.S..office buildings as well2. Use of energy in commercial buildings - U.S..Energy Information Administration (EIA)1 DataTrends: Energy Use in Office Buildings | ENERGY STAR2

• Question 324:

  Which of the following strategies helps reduce potable water demand for indoor use?

  A. Using once-through cooling equipment
  B. Installing WaterSense-labeled fixtures
  C. Increasing the number of restroom fixtures
  D. Using potable water for irrigation
  B. Installing WaterSense-labeled fixtures

  ---

  WaterSense-labeled fixtures meet EPA high-efficiency performance criteria and help reduce potable water use for restrooms and indoor plumbing fixtures, consistent with the LEED Water Efficiency category.

• Question 325:

  Which of the fallowing projects is eligible for LEED for Building Operations and Maintenance; Existing Buildings?

  A. A two-story LEED certified apartment building
  B. A park adjacent to a LEED certified building
  C. An existing single-family home that is LEED certified
  D. An existing LEED certified building located on a college campus
  D. An existing LEED certified building located on a college campus

  ---

  An existing LEED certified building located on a college campus is eligible for LEED for Building Operations and Maintenance; Existing Buildings (LEED O+M: EB). This rating system applies to existing buildings that are undergoing improvement work or little to no construction. It focuses on measuring and improving the performance of building operations and maintenance practices in areas such as energy efficiency, water conservation, waste management, indoor environmental quality, transportation, and occupant satisfaction..To be eligible for LEED O+M: EB, a project must meet certain minimum program requirements (MPRs), such as having a reasonable site boundary, being in a permanent location on existing land, being fully operational and occupied for at least one year prior to certification application, and complying with environmental laws and regulations..

• Question 326:

  Which element must be included to meet low-emitting materials requirements?

  A. Compliance with VOC limits and emissions testing
  B. Use of all-natural products
  C. Installing only recycled-content adhesives
  D. Selecting products based solely on cost
  A. Compliance with VOC limits and emissions testing

  ---

  LEED requires VOC content and emissions compliance for adhesives, paints, flooring, and furnishings under Indoor Environmental Quality.

• Question 327:

  Which permanently installed building products are addressed in the Materials and Resources Credit category calculation?

  A. Framing
  B. Elevators
  C. Process equipment
  D. Formwork for concrete
  A. Framing

  ---

  The Materials and Resources Credit category calculation addresses the permanently installed building products that are part of the building's structure, enclosure, and interior elements. These include framing, flooring, insulation, windows, doors, interior walls, ceilings, and finishes. Process equipment, elevators, furniture, and formwork for concrete are not included in the calculation ..

• Question 328:

  Which factor increases the heat island effect on a project site?

  A. High albedo
  B. Light-colored surfaces
  C. Paved surfaces
  D. High solar reflectivity index
  C. Paved surfaces

  ---

  Paved surfaces absorb and retain heat, increasing local temperatures and contributing to the heat island effect. LEED encourages mitigating this effect by using materials with high Solar Reflectance Index (SRI) or implementing strategies like green roofs and shaded areas.

• Question 329:

  Which of the following strategies reduces heat island effect for non-roof areas?

  A. Installing water features
  B. Using high-albedo paving materials
  C. Increasing turf grass coverage
  D. Adding unshaded dark asphalt
  B. Using high-albedo paving materials

  ---

  High-albedo surfaces reflect solar radiation and reduce localized heat accumulation, meeting LEED heat island reduction credit requirements.

• Question 330:

  Installing which of the following will increase the quantity of the rainwater that is discharged from a site?

  A. Vegetated roof
  B. Porous pavers for parking lots
  C. Concrete sidewalks and parking areas
  D. Bioswales and ram gardens with native plants
  C. Concrete sidewalks and parking areas

  ---

  Installing concrete sidewalks and parking areas will increase the quantity of the rainwater that is discharged from a site. Rainwater is the water that falls as precipitation on a site. Rainwater discharge is the amount of rainwater that leaves a site as surface runoff or subsurface flow. Rainwater discharge can affect the quantity and quality of water resources downstream by causing erosion, flooding, sedimentation, pollution, and habitat loss..Concrete sidewalks and parking areas are examples ofimpervious surfaces that prevent rainwater from infiltrating intothe soil and increase rainwater discharge by creating more runoff1...
