USGBC LEED-GA Online Questions & Answers

• Question 131:

  Which of the following does a facility operator need in order to optimize water consumption?

  A. Submetering systems
  B. Schedules of the occupants
  C. Operating times of the building
  D. Fixture cutsheets of waterless urinals
  A. Submetering systems

  ---

  Submetering systems are devices that measure the water consumption of specific building components, such as cooling towers, irrigation systems, process water systems, or tenant spaces..They allow the facility operator to monitor and optimize the water use of different systems and identify any leaks or inefficiencies12..Submetering systems are also required for some LEED credits, such as Water Metering and Cooling Tower Water Use3.

• Question 132:

  Good site design benefits a project in which of the following ways?

  A. Makes occupants comfortable by providing green spaces
  B. Supports access to diverse land uses, sustainable food and services
  C. Provides access to public transportation and employment opportunities
  D. Protects endangered species and maximizes development of previously undeveloped areas
  A. Makes occupants comfortable by providing green spaces

  ---

  Good site design benefits a project in which of the following ways: makes occupants comfortable by providing green spaces. Green spaces are areas of vegetation that improve the quality of life for building occupants and visitors by providing natural views, fresh air, shade, noise reduction, and recreational opportunities. They also reduce heat island effect, improve stormwater management, and sequester carbon dioxide. The LEED Green Associate Candidate Handbook states that one of the intents of the

  Sustainable Sites category is to "enhance occupant comfort by providing green spaces" [1, p. 13]..

• Question 133:

  Light colored paving and cool roofs are terms referring to materials with

  A. lower emissivity and lower albedo
  B. lower emissivity and higher albedo
  C. higher emissivity and lower albedo
  D. higher emissivity and higher albedo
  D. higher emissivity and higher albedo

  ---

  Light-colored paving and cool roofs refer to materials with higher emissivity and higher albedo. Emissivity is the ability of a material to emit heat that it absorbs, while albedo is a measure of how much light that hits a surface is reflected without being absorbed. Materials with high emissivity can help reduce heat islands by releasing more of the heat they absorb, while those with high albedo can reflect more sunlight and thus stay cooler..

• Question 134:

  Which organization designed the Minimum Efficiency Reporting Value (MERV) measurement scale that rates the effectiveness of air filters?

  A. U.S. Department of Energy (DOE)
  B. American National Standards Institute (ANSI)
  C. U.S. Environmental Protection Agency
  D. ASHRAE
  D. ASHRAE

  ---

  ASHRAE developed the MERV scale, which rates air filter efficiency in capturing airborne particles. LEED references MERV ratings in Indoor Environmental Quality credits to ensure air quality.

• Question 135:

  Which type of water should be considered an alternative water source?

  A. Rainwater
  B. Dirty water
  C. Blackwater
  D. Potable water
  A. Rainwater

  ---

  Rainwater is considered an alternative water source because it is a sustainable source of water that is not supplied from fresh surface water or groundwater. Rainwater can be harvested from roofs or other surfaces and stored for later use. Rainwater can offset the demand for freshwater and reduce the pressure on water resources. Rainwater can be used for various purposes, such as irrigation, toilet flushing, cooling, and cleaning..LEED projects can earn credits for using alternative water sources under the Water Efficiency category..

• Question 136:

  Strategies for improving building occupants' comfort and control may consist of

  A. ensuring adequate ventilation, monitoring carbon dioxide and prohibiting smoking
  B. installing operable windows, giving occupants lighting control and providing ergonomic furniture
  C. designing for proper ventilation, monitoring outdoor airflow and including appropriate acoustic design
  D. specifying low-emitting materials, testing for radon and other on-site contaminants and installing entryway grates
  B. installing operable windows, giving occupants lighting control and providing ergonomic furniture

  ---

  Strategies for improving building occupants' comfort and control may consist of installing operable windows, giving occupants lighting control and providing ergonomic furniture. These strategies can enhance 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. Installing operable windows can allow occupants to adjust the natural ventilation, temperature, and fresh air intake of their spaces. Giving occupants lighting control can allow them to adjust the artificial lighting levels, color, and direction of their spaces..Providing ergonomic furniture can support the physical comfort, posture, and well-being of the occupants12..

• Question 137:

  Which strategy addresses acoustical comfort requirements?

  A. Mechanical system silencing
  B. Increasing reverberation
  C. Using high-VOC sound panels
  D. Avoiding acoustic evaluations
  A. Mechanical system silencing

  ---

  Reducing mechanical noise supports acoustic performance in Schools and other rating systems.

• Question 138:

  Which of the following scenarios would potentially help a project earn the most LEED points?

  A. Renovate an abandoned shopping mall in a low-density area outside the city
  B. Build an office and apartment building near an interstate highway and an existing shopping mall
  C. Renovate a large building in a diverse, walkable business district and central transit connectivity
  D. Build a low-density project on a greenfield site outside the city in order to mitigate environmental impact
  C. Renovate a large building in a diverse, walkable business district and central transit connectivity

  ---

  This scenario would potentially help a project earn the most LEED points because it aligns with the goals and criteria of the LEED v4 Location and Transportation category,which aims to reduce the environmental and human health impacts of transportation and promote sustainable site selection1. By renovating a large building in a diverse, walkable business district and central transit connectivity, the project can: Preserve existing buildings and reduce the demand for new construction materials and land development Enhance the livability, vitality, and diversity of the urban area and support mixed-use development Provide access to quality transit options and reduce the reliance on private vehicles, lower greenhouse gas emissions, and encourage alternative modes of travel Support walkability and connectivity to various amenities and services within walking distance Avoid locating on sensitive lands or prime farmland that could support open space, habitat, or agriculture These strategies can help the project earn points for various credits under theLocation and Transportation category, such as LEED for Neighborhood Development Location, Surrounding Density and Diverse Uses, Access to Quality Transit, Bicycle Facilities, Reduced Parking Footprint, High Priority Site and Equitable Development.

• Question 139:

  Which of the following falls under the Energy and Atmosphere credit category?

  A. Interior Lighting
  B. Heat Island Reduction
  C. Cooling Tower Water Use
  D. Enhanced Refrigerant Management
  D. Enhanced Refrigerant Management

  ---

  The Energy and Atmosphere (EA) category addresses the energy performance, efficiency, and renewable sources of buildings. One of the credits in this category is EA Credit: Enhanced Refrigerant Management, which aims to reduce the emissions of ozone-depleting substances and greenhouse gases from refrigeration and air-conditioning equipment. Refrigerants are substances that are used to transfer heat in cooling systems. Some refrigerants have high global warming potential (GWP) and ozone depletion potential (ODP), which means they can contribute to climate change and damage the ozone layer if they leak or are improperly disposed of..Enhanced refrigerant management involves selecting refrigerants with low GWP and ODP, minimizing refrigerant charge size, and preventing or detecting leaks12..
