• Question 121:

  Which of the following strategies are used to address Transportation in Operation and Maintenance under the Location and Transportation LEED Category?

  A. Use xeriscaping
  B. Offer financial incentives
  C. Minimize impervious areas
  D. Size the building appropriately
  B. Offer financial incentives

  ---

  Offering financial incentives is a strategy that can be used to address transportation in operation and maintenance under the Location and Transportation (LT) category. The LT category addresses the location and accessibility of a project site, as well as its impacts on transportation, land use, and community connectivity. One of the credits in this category is LTCredit: Alternative Transportation - Transportation Demand Management, which rewards projects that implement programs or policies that reduce single-occupancy vehicle trips and encourage alternative transportation modes, such as public transit, carpooling, biking, or walking..Offering financial incentives is one example of such a program or policy, which can provide benefits or rewards for the employees or tenants who use alternative transportation modes, such as subsidies, vouchers, discounts, prizes, recognition, or preferential parking1...

• Question 122:

  By specifying the installation of occupancy sensors for the building's lighting system, what pair of LEED credit categories would be affected?

  A. Innovation and Water Efficiency
  B. Integrative Process and Sustainable Sites
  C. Location and Transportation and Materials and Resources
  D. Indoor Environmental Quality and Energy and Atmosphere
  D. Indoor Environmental Quality and Energy and Atmosphere

  ---

  Occupancy sensors are devices that detect the presence or absence of people in a space and automatically turn the lights on or off accordingly. By installing occupancy sensors for the building's lighting system, projects can achieve two benefits: improving the indoor environmental quality (IEQ) and reducing the energy consumption. Occupancy sensors can enhance the IEQ by providing lighting control for individual spaces, allowing occupants to adjust the light levels to their preferences and needs.

  Occupancy sensors can also save energy by avoiding unnecessary lighting when spaces are unoccupied, thus lowering the electricity demand and greenhouse gas emissions..

• Question 123:

  Which lighting strategy improves occupant comfort?

  A. Disabling all controls
  B. Providing glare control with blinds or shades
  C. Installing only high-intensity task lights
  D. Removing daylighting devices
  B. Providing glare control with blinds or shades

  ---

  Glare control is required under IEQ: Daylight and enhances visual comfort.

• Question 124:

  Which Is a component of a construction waste management plan?

  A. List of materials to be diverted from disposal
  B. Projected cost savings from diverting waste
  C. Quantity of waste generated from excavated soil
  D. Distance of the recycling facility from the project site
  A. List of materials to be diverted from disposal

  ---

  A list of materials to be diverted from disposal is a component of a construction waste management plan. A construction waste management plan is a document that outlines the goals, procedures, and responsibilities for diverting construction and demolition waste from landfills or incinerators. A list of materials to be diverted from disposal identifies the types and quantities of materials that can be recycled, reused, salvaged, or donated, as well as the destinations and methods for diversion. The other options

  are not components of a construction waste management plan. Projected cost savings from diverting waste is a potential benefit of implementing a construction waste management plan, but it is not a required component. Quantity of waste generated from excavated soil is a factor that affects the construction waste generation rate, but it is not a component of a construction waste management plan. Distance of the recycling facility from the project site is a factor that affects the transportation emissions and

  costs associated with diverting waste, but it is not a component of a construction waste management plan..

• Question 125:

  Which of the following is a minimum program requirement for LEED@ for New Construction and Major Renovations projects?

  A. Be a permanent building or space on existing land
  B. Commit to sharing data for water usage only
  C. Comply with maximum floor area requirements
  D. Comply with maximum ventilation rate requirements
  A. Be a permanent building or space on existing land

  ---

  A minimum program requirement for LEED for New Construction and Major Renovations projects is to be a permanent building or space on existing land. This means that the project must be designed and constructed for a fixed location on land that is legally defined and has legal boundaries. The project cannot be a temporary structure, such as a trailer or a tent, or a movable structure, such as a boat or a vehicle. The LEED Green Associate Candidate Handbook states that this is one of the four minimum

  program requirements that apply to all LEED rating systems [1, p. 9]..

• Question 126:

  Which item is considered a plug load?

  A. Chillers
  B. Packaged rooftop units
  C. Desk lamps and computers
  D. Elevator motors
  C. Desk lamps and computers

  ---

  Plug loads (receptacle loads) include user-controlled devices like computers and desk lamps.

• Question 127:

  Which strategy for roof coverage best addresses both heat island effect and rainwater runoff from the roof only?

  A. 100% vegetated
  B. 100% high-albedo
  C. 20% high-albedo and 80% conventional
  D. 50% standing seam copper and 50% vegetated
  A. 100% vegetated

  ---

  A 100% vegetated roof coverage best addresses both heat island effect and rainwater runoff from the roof only. A vegetated roof, also known as a green roof, is a layer of living plants thatcovers the roof surface. A vegetated roof reduces the heat island effect by providing shade, evapotranspiration, and insulation, lowering the roof temperature and the surrounding air temperature. A vegetated roof also reduces rainwater runoff by retaining and absorbing precipitation, decreasing the volume and peak flow of

  stormwater leaving the roof. The other options are not as effective as a 100% vegetated roof coverage in addressing both heat island effect and rainwater runoff from the roof only. A 100% high-albedo roof reflects more solar radiation than a conventional roof, reducing the heat island effect, but it does not reduce rainwater runoff. A 20% high-albedo and 80% conventional roof has a lower reflectance than a 100% high-albedo roof, resulting in a higher heat island effect, and it does not reduce rainwater runoff

  either. A 50% standing seam copper and 50% vegetated roof has a lower vegetated area than a 100% vegetated roof, resulting in less shade, evapotranspiration, insulation, retention, and absorption, leading to a higher heat island effect and more rainwater runoff..

• Question 128:

  What organization reviews and provides final LEED certification report to projects?

  A. U.S. Green Building Council
  B. Green Building Initiative (GBI)
  C. Green Business Certification Inc.
  D. ASHRAE
  C. Green Business Certification Inc.

  ---

  The Green Business Certification Inc. (GBCI) reviews and provides the final LEED certification report to projects. GBCI was established in 2008 as a separately incorporated entity with the support of the U.S. Green Building Council (USGBC). GBCI administers project certifications for LEED and other green business certification programs..

• Question 129:

  Use of which of the following can help reduce the heat gain and peak air temperatures?

  A. A drip irrigation system
  B. Pervious paving materials
  C. Low albedo paving materials
  D. High reflectance roofing materials
  D. High reflectance roofing materials

  ---

  High reflectance roofing materials can help reduce heat gain and peak air temperatures by reflecting more sunlight away from the building, thereby reducing the amount of heat absorbed by the roof. This can lead to lower cooling loads and energy use for air conditioning..

• Question 130:

  Which credit category attempts to reduce light pollution and discourages the development of previously undeveloped land?

  A. Regional Priority
  B. Sustainable Sites
  C. Energy and Atmosphere
  D. Location and Transportation
  B. Sustainable Sites

  ---

  The Sustainable Sites (SS) category addresses the site selection, design, construction, and operation of a project, as well as its impacts on the natural and built environment. One of the goals of this category is to reduce light pollution and discourage the development of previously undeveloped land. Light pollution is the excessive or inappropriate use of artificial lighting that can have adverse effects on human health, wildlife, ecosystems, and astronomy. Previously undeveloped land is land that has not been graded, cleared, or built upon prior to the current project and remains in a natural state..Developingpreviouslyundeveloped land can result in habitat loss, soil erosion, stormwater runoff, and increased infrastructure costs13..
