USGBC LEED-GA Online Questions & Answers

• Question 71:

  Minimizing impervious surfaces, protecting soils, and enhancing native vegetation are all strategies that:

  A. Optimize outdoor water use
  B. Reduce light pollution
  C. Decrease construction activity pollution
  D. Improve rainwater management
  D. Improve rainwater management

  ---

  These strategies are core components ofLow Impact Development (LID)andgreen infrastructureapproaches

  for rainwater management:

  "LID emphasizes... minimizing land disturbance, preserving vegetation, minimizing impervious cover..."

  These help reduce runoff volume and replicate the site's natural hydrology, improving rainwater management.

• Question 72:

  Which of the following techniques IS recommended for preventing the negative effects of indoor pollutants?

  A. Deep cleaning all surfaces during occupant move-in
  B. Keeping material containers open during construction
  C. Specifying and installing low-emitting materials at the source
  D. Keeping doors and windows open after installation of interior finishes
  C. Specifying and installing low-emitting materials at the source

  ---

  Low-emitting materials are those that have minimal or no emissions of volatile organic compounds (VOCs) and other harmful pollutants that can affect indoor air quality (IAQ)1..Specifying and installing low-emitting materials at the source can help prevent the negative effects of indoor pollutants by reducing the exposure of occupants and workers tothese substances2..Some examples of low-emitting materials are paints, coatings, adhesives, sealants, flooring, furniture, and insulation that meet the criteria of third-party certification programs such as Green Seal, Greenguard, or SCS3.

• Question 73:

  What is the percentage rule when making a decision on the rating system that is most appropriate to use for a project?

  A. 30/70 rule
  B. 40/60 rule
  C. 50/50 rule
  D. 60/40 rule
  B. 40/60 rule

  ---

  The percentage rule is a method to determine the most appropriate LEED rating system for a project when several rating systems may be applicable1..To use this rule, first assign a rating systemto each square foot or square meter of the building, and then choose the most appropriate rating system based on the resulting percentages1..The entire gross floor area of a LEED project must be certified under a single rating system and is subject to all prerequisites andattempted credits in that rating system1..The percentage rule states that if one rating system covers more than 60% of the gross floor area, that rating system should be used1..If no rating system covers more than 60% of the gross floor area, but one covers more than 40%, then that rating system should be used1..If no rating system covers more than 40% of the gross floor area, then the project team can choose any applicable rating system1. Therefore, the answer is B. 40/60 rule. LEED rating system selection guidance

• Question 74:

  An office without transit access can substantially reduce its transportation impact if

  A. ample parking spaces are provided
  B. the office is located at a major intersection
  C. workers are able to walk from the office to basic services
  D. green power is purchased to offset projected automobile travel
  C. workers are able to walk from the office to basic services

  ---

  An office without transit access can substantially reduce its transportation impact if workers are able to walk from the office to basic services. Transportation impact is the effect of transportation activities on the environment, society, and economy. Transportation impact can include greenhouse gas emissions, air pollution, noise pollution, energy consumption, land use, traffic congestion, infrastructure costs, and public health. Walking is a form of alternative transportation that can reduce transportation impact by using less energy, emitting less pollutants, occupying less space, and improving physical activity and well-being..If workers are able to walk from the office to basic services, such as retail, restaurants, banks, or post offices, they can reduce their vehicle miles traveled, fuel consumption, and parking demand1...

• Question 75:

  Lighting controls are typically installed in buildings in order to:

  A. Prevent building managers from making changes to the light levels
  B. Improve occupant comfort and save energy throughout the building
  C. Filter glare produced by overhead fixtures and prevent ultraviolet radiation from reaching building occupants
  D. Provide a uniform light level across every space in a building
  B. Improve occupant comfort and save energy throughout the building

  ---

  According to the LeadingGreen Guide:

  "Individual controls for lighting have a significant effect on occupants' comfort. Meeting the unique needs of

  each occupant can be accomplished through effective design of lighting controls..."

  LEED credits under EQc6 emphasize providing lighting comfort and energy savings through such controls.

• Question 76:

  Which of the following project types and scopes are addressed by LEED rating systems?

  A. LEED Operations and Maintenance: Schools
  B. LEED Interior Design and Construction: Data Centers
  C. LEED Building Design and Construction: Existing Buildings
  D. LEED Neighborhood Development: Warehouses and Distribution
  B. LEED Interior Design and Construction: Data Centers

  ---

  LEED Interior Design and Construction (ID+C) is a rating system that applies to projects that are a complete interior fit-out or renovation1..Data centers are one of the project types that can use this rating system, as they have specific requirements for energy efficiency, cooling, and reliability.

• Question 77:

  According to LEED. which of the following should be considered when locating a site for a project?

  A. Political landscape
  B. Infrastructure context
  C. Economic stability
  D. Revenue generating possibilities
  B. Infrastructure context

  ---

  According to LEED, one of the factors that should be considered when locating a site for a project is the infrastructure context. The infrastructure context refers to the existing physical systems that support a site, such as roads, utilities, transit networks, water supply, wastewater treatment, stormwater management, and waste disposal. Choosing a site that has access to adequate infrastructure can reduce the environmental impacts of developing new infrastructure, such as land disturbance, resource

  consumption, energy use, emissions, and pollution. The LEED Green Associate Candidate Handbook states that one of the intents of the Location and Transportation category is to "reduce environmental harm from transportation infrastructure" [1, p. 12]..

• Question 78:

  What is a core benefit of daylighting?

  A. Increased cooling loads without exception
  B. Improved visual comfort and reduced artificial lighting demand
  C. Increased glare in all occupied areas
  D. Reduced need for building insulation
  B. Improved visual comfort and reduced artificial lighting demand

  ---

  Daylighting improves occupant well-being and reduces energy use for lighting.

• Question 79:

  To attain the Integrative Process Credit, a project team must identify

  A. synergies between systems
  B. tenant design and construction guidelines
  C. community outreach strategies
  D. order of phase completion
  A. synergies between systems

  ---

  The Integrative Process Credit in LEED v4 requires the project team to implement an integrative process that enables themto discover unique opportunities for enhancing project performance and environmental benefits1..The project team should identify and use opportunities to achieve synergies across disciplines and building systems2.

  What is a primary benefit achieved through building commissioning?

  A. Faster construction schedule
  B. Reduced system performance
  C. Ensured systems operate as intended
  D. Increased energy consumption
  C. Ensured systems operate as intended

  ---

  Commissioning verifies design intent, proper installation, and operational performance, satisfying the EA Fundamental Commissioning prerequisite.
