• Question 151:

  Which of the following is a component of the Promote Sustainable and Regenerative Material Resource Cycles impact category?

  A. Move to Cyclical, Non-Depleting Material Cycles
  B. Protect Human Health Globally and Across the Built Environment Life Cycle
  C. Protection and Restoration of Water Regimes and Natural Hydrological Cycles
  D. Greenhouse Gas (GHG) Emissions Reduction from the Embodied Energy of Materials
  A. Move to Cyclical, Non-Depleting Material Cycles

  ---

  The Promote Sustainable and Regenerative Material Resource Cycles impact category in LEED encourages the use of materials that can be continually cycled back into the same system at their end-of-life. This is referred to as moving to cyclical, non-depleting material cycles. It promotes the use of renewable or recyclable materials and reduces waste..

• Question 152:

  Which of the following negative impacts on the environment are a result of waste being transported/diverted to landfills?

  A. Increased pre-consumer recycled content
  B. Decreased post-consumer recycled content
  C. Waste is incinerated and used to generate energy
  D. Solid waste produces methane and potent greenhouse gas
  C. Waste is incinerated and used to generate energy

  ---

  Waste that is transported or diverted to landfills can have negative impacts on the environment, such as occupying valuable land, contaminating soil and water, and emitting harmful gases. One of the most significant impacts is the production of methane, a potent greenhouse gas that contributes to global warming and climate change. Methane is generated when organic waste decomposes anaerobically (without oxygen) in landfills..Methane has a global warming potential 28 times higher than carbon dioxide over a 100-year period..

• Question 153:

  The project team is conducting a feasibility study of a building project. The developer has pre-qualified four potential sites that are all financially viable. Within the context of LEED, which site is the most applicable?

  A. A brownfield site with no access to metro
  B. A brownfield site in a national park with car access only
  C. A greenfield site with access to public transport and proximity to grocery stores
  D. A brownfield site with access to five lines of public transportation and basic services
  D. A brownfield site with access to five lines of public transportation and basic services

  ---

  From a LEED perspective, a brownfield site with access to multiple lines of public transportation and basic services would be the most applicable. Brownfield sites are previously developed sites that may be contaminated with hazardous waste or pollution. Developing on these sites can help to clean up and revitalize the area. Access to public transportation reduces the need for private vehicle use,reducing carbon emissions and traffic congestion..

• Question 154:

  What do the credits in the Materials and Resources category focus on?

  A. Reducing the quantity of materials used on a project
  B. Selecting materials that are more energy efficient than traditional building materials
  C. Minimizing the embodied impacts associated With the entire life-cycle of building materials
  D. Helping project teams select materials that have the most environmental benefits at the least cost
  C. Minimizing the embodied impacts associated With the entire life-cycle of building materials

  ---

  The Materials and Resources (MR) category focuses on reducing the environmental, economic, and social impacts of building materials from extraction to disposal..It encourages the use of materials that have lower embodied energy, less waste, more recycled content, and better life-cycle performance.

• Question 155:

  ASHRAE standards are applicable to which of the following LEED categories?

  A. Sustainable Sites and Energy and Atmosphere
  B. Materials and Resources and Sustainable Sites
  C. Water Efficiency and Indoor Environmental Quality
  D. Energy and Atmosphere and Indoor Environmental Quality
  D. Energy and Atmosphere and Indoor Environmental Quality

  ---

  ASHRAE stands for the American Society of Heating, Refrigerating and Air-Conditioning Engineers, a professional organization that develops standards and guidelines for the design, operation, and maintenance of buildings. ASHRAE standards are applicable to two LEED categories: Energy and Atmosphere (EA) and Indoor Environmental Quality (IEQ). The EA category addresses the energy performance, efficiency, and renewable sources of buildings. The IEQ category addresses the indoor air quality,

  thermal comfort, lighting quality, and acoustic performance of buildings..Some of the ASHRAE standards that are relevant for these categories are: ASHRAE Standard 90.1 for energy efficiency;ASHRAE Standard 62.1 for ventilation; ASHRAE Standard 55 for thermal comfort; ASHRAE Standard 189.1 for high-performance green buildings1...

• Question 156:

  How is an exemplary performance point earned if the credit is available for exemplary performance per the Reference Guide?

  A. Submit a Project CIR
  B. Increase performance by 25%
  C. Verify that precedent has been established
  D. Meet the indicated incremental performance threshold
  D. Meet the indicated incremental performance threshold

  ---

  An exemplary performance point is earned if the project achieves a performance level that is significantly higher than the credit requirements, as specified in the LEED Reference Guide1..The incremental performance threshold varies depending on the credit and is typically double the credit requirements or the next percentage threshold.

• Question 157:

  What do team members enhance by collaboration during the integrative process?

  A. Project duration
  B. Life-cycle costs
  C. Construction costs
  D. Efficiency and effectiveness of systems
  D. Efficiency and effectiveness of systems

  ---

  The integrative process involves collaboration among all project team members, from initial planning through design and construction, to enhance the efficiency and effectiveness of systems. This process allows for better coordination among disciplines, leading to more efficient use of resources, improved environmental performance, reduced project costs, and enhanced occupant satisfaction..

• Question 158:

  Which term describes misinformation presented to consumers to portray a product or policy as being more environmentally friendly than it is?

  A. Biomimicry
  B. Greenwashing
  C. Green infrastructure
  D. Environmental certification
  B. Greenwashing

  ---

  Greenwashing is a term that describes misinformation presented to consumers to portray a product or policy as being more environmentally friendly than it is. Greenwashing can be done by using vague or misleading claims, false labels or certifications, irrelevant or exaggerated benefits, or hidden trade-offs..Greenwashing can deceive consumers into buying products or supporting policies that are not trulygreen, and undermine the credibility and effectiveness of genuine green initiatives...

• Question 160:

  What standard ensures adequate ventilation is supplied to building occupants?

  A. ASHRAE 55
  B. ASHRAE 62.1
  C. ASHRAE 90.1
  D. ASHRAE 189.1
  B. ASHRAE 62.1

  ---

  ASHRAE 62.1 is a standard that ensures adequate ventilation is supplied to building occupants. ASHRAE stands for the American Society of Heating, Refrigerating and Air-ConditioningEngineers, a professional organization that develops standards and guidelines for the design, operation, and maintenance of buildings. ASHRAE 62.1 is a standard that specifies the minimum ventilation rates and other measures for new and existing buildings that are intended to provide acceptable indoor air quality (IAQ) for the occupants. Ventilation is the process of supplying outdoor air to or removing indoor air from a building..Adequate ventilation is important for maintaining good IAQ, which can affectthe health, comfort, and productivity of the occupants13..
