USGBC LEED-GA Online Questions & Answers

• Question 341:

  Which of the following is a source of graywater?

  A. Toilets
  B. Urinals
  C. Sprinklers
  D. Lavatory faucets
  D. Lavatory faucets

  ---

  Graywater refers to relatively clean wastewater from domestic activities such as washing dishes, laundry, and bathing. Water from lavatory faucets falls into this category. Graywater can be treated and reused for non-potable purposes such as toilet flushing or irrigation, which can help conserve water..

• Question 342:

  The intent of the location valuation factor is to incentivize the purchase of products that

  A. reduce transportation emissions
  B. support the local economy and workers
  C. emit no Volatile Organic Compounds (VOCs)
  D. comply With responsible extraction regulations
  A. reduce transportation emissions

  ---

  The location valuation factor is a concept that applies to several credits under the Materials and Resources credit category in LEED v4..It means that if the purchased products or materials are extracted, manufactured, and purchased within 100 miles (160 kilometers) of the project, LEED will award the project in the credit calculations by valuing those products at 200% of their cost1..This is to incentivize the purchase of products that reduce transportation emissions and environmental impacts associated with

  long-distance shipping2.

• Question 343:

  Which of the following is the reason Regional Priority credits are awarded?

  A. To help meet economic goals
  B. To encourage exemplary performance
  C. To address local environmental issues
  D. To promote innovation in building design
  C. To address local environmental issues

  ---

  Regional Priority credits are awarded to encourage projects to address local environmental issues that are of particular importance or concern for the region where the project is located. These issues may include water scarcity, air quality, habitat protection, or human health. Regional Priority credits are not new LEED credits, but rather existing credits that have been identified by regional councils or chapters of USGBC as having higher priority or relevance for their areas..Projects can earn up to four bonus points by achieving Regional Priority credits..

• Question 344:

  Which of the following strategies prioritizes cost-effectiveness when designing a LEED project?

  A. Onsite renewable systems
  B. Enhanced Commissioning (Cx)
  C. Measuring and verifying systems performance for one year
  D. Applying an integrative design process
  D. Applying an integrative design process

  ---

  An integrative design process is a collaborative and holistic approach that involves the project team and stakeholders from the early stages of the project to identify the project goals, analyze the site and climate conditions, explore multiple design options, and optimize the performance and cost-effectiveness of the project..By applying an integrative design process, a LEED project can achieve higherlevels of sustainability and efficiency, as well as reduce the risks of errors, delays, and change orders12..

• Question 345:

  Where could a project be located to purchase Renewable Energy Certificates (RECs)?

  A. Almost anywhere
  B. Where utilities are deregulated
  C. Only with cooperating local utilities or power markets
  D. Near hydroelectric dams, wind farms or other sources of renewable energy
  A. Almost anywhere

  ---

  Renewable Energy Certificates (RECs) are tradable, non-tangible energy commodities that represent the environmental attributes of one megawatt-hour of electricity generated from renewable sources, such as wind, solar, hydro, or biomass1..RECs can be purchased by anyone, regardless of their location or utility provider, to support the development of renewable energy and reduce their carbon footprint2..RECs can also help projects earn points for the LEED v4 Innovation credit for Green Power and Carbon Offsets,which requires the purchase of at least 50% of the total building energy use from renewable sources or offsets for a minimum of five years.

• Question 346:

  Light trespass beyond the project boundary can be prevented by the use of

  A. flood light fixtures
  B. up-lighting fixtures
  C. shielded light fixtures
  D. increasing the number of light fixtures
  C. shielded light fixtures

  ---

  Shielded light fixtures are designed to direct light downwards and prevent it from spilling over into areas where it's not wanted, such as beyond the project boundary. This helps to prevent light trespass, which can be a form of pollution that disrupts ecosystems and human sleep patterns..

• Question 347:

  A wood product that is certified by the Forest Stewardship Council (FSC) is guaranteed to be

  A. grown in a tropical forest
  B. harvested from a well-managed source
  C. packaged with environmentally friendly materials
  D. purchased from a LEED AP
  B. harvested from a well-managed source

  ---

  The Forest Stewardship Council (FSC) is an independent, non-governmental organization that promotes responsible management of the world's forests. FSC sets standards for forest management that ensure environmental, social, and economic benefits for present and future generations. FSC also certifies forest products that meet its standards through a chain of custody system that tracks the origin and processing of the products..A wood product that is certified by FSC is guaranteed to be harvested from a well-managed source that protects biodiversity, respects indigenous rights, maintains forest productivity, and supports local communities1...

• Question 348:

  Solar Reflectance Index (SRI) combines reflectivity with:

  A. Transmissivity
  B. Emissivity
  C. Absorptivity
  D. Conductivity
  B. Emissivity

  ---

  SRI is a measure of a material's ability to reflect solar heat (reflectivity) and release absorbed heat (emissivity). This index helps evaluate materials for reducing the heat island effect under the Sustainable Sites category.

• Question 349:

  Volatile organic compounds (VOCs) negatively impact which of the following entities?

  A. Quality of daylight
  B. Quality of indoor air
  C. Durability of a product
  D. Ability to recycle a product
  B. Quality of indoor air

  ---

  Volatile organic compounds (VOCs) are compounds that have a high vapor pressure and low water solubility, and are emitted as gases from certainsolids or liquids1..VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects2..Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors2..VOCs are emitted by a wide array of products, such as paints, solvents, cleaners, fuels, pesticides, building materials, office equipment, etc2..Breathing VOCs can irritate the eyes, nose andthroat, can cause difficulty breathing and nausea, and can damage the central nervous system and other organs3..Some VOCs can cause cancer3. Therefore, VOCs negatively impact the quality of indoor air, which is option B.

• Question 350:

  A project team has three principal participants with LEED AP credentials. One is an energy modeler, one is a civil engineer and the third one is a general contractor. Under which category can their credentials contribute a point?

  A. Innovation
  B. Commissioning (Cx)
  C. Sustainable Sites
  D. Energy and Atmosphere
  A. Innovation

  ---

  LEED AP credentials can contribute a point under the Innovation category, which rewardsprojects for achieving exceptional or innovative performance above the requirements set by the LEED rating system12..Having a LEED AP with specialty on the projectteam is one of the possible strategies to earn this point, as it demonstrates expertise and commitment to the green building process34..The specialty credential must match the rating system of the project.
