• Question 81:

  Which type of site Is appropriate for development of LEED projects?

  A. Floodplain
  B. Greenfield
  C. Brownfield
  D. Undeveloped
  C. Brownfield

  ---

  A brownfield site is appropriate for development of LEED projects because it is a site that has been previously used for industrial or commercial purposes and may be contaminated by pollutants or hazardous substances. Developing a brownfield site can help reduce environmental impacts, such as soil erosion, habitat loss, and water consumption, by reusingexisting infrastructure and restoring degraded land..LEED projects can earn credits for developing on brownfield sites under the Sustainable Sites category..

  Which of the following is a strategy for preventing light pollution?

  A. Install up-lighting
  B. Install shielded fixtures
  C. Install high performance windows
  D. Use dark paving materials to diminish light distribution
  B. Install shielded fixtures

  ---

  A strategy for preventing light pollution is to install shielded fixtures. Light pollution is the excessive or inappropriate use of artificial lighting that can have adverse effects on human health, wildlife, ecosystems, and astronomy. Shielded fixtures are lighting devices that direct light downward and prevent light from escaping upward or sideways..Shielded fixtures can reduce light pollution by minimizing glare, sky glow, light trespass, and energy waste..

• Question 84:

  The most efficient way for building users to rate the heating and air-conditioning and other aspects of work spaces is through

  A. an occupant survey
  B. a meeting with the owner
  C. a facilities manager survey
  D. a meeting with the line manager
  A. an occupant survey

  ---

  An occupant survey is the most efficient way for building users to rate the heating and air-conditioning and other aspects of work spaces. An occupant survey is a tool that collects feedback from building occupants about their satisfaction with various aspects of their indoor environment, such as thermal comfort, lighting quality, acoustic quality, air quality, and spatial layout. An occupant survey can help identify areas for improvement, monitor performance, evaluate design strategies, and inform future

  decisions. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving indoor environmental quality is to "conduct occupant surveys on thermal comfort" [1, p. 16]..

• Question 85:

  What is a benefit of submetering water systems?

  A. It eliminates the need for efficient fixtures
  B. It helps identify leaks and inefficiencies
  C. It increases indoor water consumption
  D. It replaces building-level metering
  B. It helps identify leaks and inefficiencies

  ---

  Submeters allow monitoring of individual water uses and help detect excessive consumption patterns or leaks, supporting Water Metering credit compliance.

• Question 86:

  At what phase should the charrette take place?

  A. Post commissioning
  B. During the design process
  C. At the Beginning of the project
  D. During the construction process
  C. At the Beginning of the project

  ---

  A charrette is a collaborative workshop that brings together various stakeholders and experts to address a particular design issue, such as sustainability, security, or accessibility. A charrette should take place at the beginning of the project, when the project goals, scope, and budget are being defined, and when the most impact can be made with the least cost. A charrette can help establish a shared vision, identify potential challenges and opportunities, and generate innovative and integrated solutions. .A Handbook for Planning and Conducting Charrettes for High-Performance Projects, page 1-2; LEED v4 Green Associate Candidate Handbook, page 12.

• Question 87:

  A retail store is pursuing LEED for Interior Design and Construction certification. Which of the following strategies should be conducted first?

  A. Perform a life-cycle analysis
  B. Create an energy budget analysis
  C. Conduct a charrette with the project team
  D. Perform an energy model according to ASHRAE 90.1
  C. Conduct a charrette with the project team

  ---

  A charrette is an intensive planning session where citizens, designers, and others collaborate on a vision for development. It provides a forum for ideas and offers the unique advantage of giving immediate feedback to the designers. More importantly, it allows everyone who participates to be a mutual author of the plan. This should be conducted first to ensure all stakeholders are aligned on the project goals and strategies before proceeding with detailed analyses or modeling..

• Question 88:

  What is considered as the receptacle load?

  A. The electrical current drawn by regulated and non-regulated receptacles
  B. The electrical current drawn by the individual receptacle connected to a standby battery
  C. The electrical current Which is non-regulated and has major impact on the load 0t the overall network
  D. The electrical current drawn by all equipment that is connected to the electrical system via a wall outlet
  D. The electrical current drawn by all equipment that is connected to the electrical system via a wall outlet

  ---

  receptacle load is the electrical load that is connected to the building's electrical system through receptacles (also known as outlets or sockets). Receptacle load includes both regulated and non-regulated loads, such as computers, printers, monitors, lamps, refrigerators, microwaves, coffee makers, etc..Receptacle load does not include hard-wiredequipment, such as lighting fixtures, HVAC systems, or elevators12. Receptacle load is one of the major components of plug and process loads (PPLs), which consume about 47% of primary energy in U.S..commercial buildings2. Reducing receptacle load can help improve building energy efficiency and achieve LEED certification. One of the strategies to reduce receptacle load is to use automatic receptacle controls, which are devices that turn off or reduce power to receptacles when they are not in use..Automatic receptacle controls are required by ANSI/ASHRAE/IES Standard 90.1-2019: Energy Standard for Buildings Except Low-Rise Residential Buildings, as well as NIH DRM 10.5.313.

• Question 89:

  Which of the following benefits pertain to purchasing and installing locally sourced. environmentally preferable products?

  A. Products contain recycled content
  B. Products are long lasting and durable
  C. The environmental harm associated with transportation is reduced
  D. Factories that support human health and workers' rights are used
  C. The environmental harm associated with transportation is reduced

  ---

  The environmental harm associated with transportation is reduced when purchasing and installing locally sourced, environmentally preferable products. Locally sourced products are products that are extracted, harvested, recovered, or manufactured within a certain distance from the project site. Environmentally preferable products are products that have reduced environmental impacts compared to similar products in terms of energy use, water use, materials use, waste generation, emissions, toxicity, and

  durability. Purchasing and installing locally sourced, environmentally preferable products reduces the amount of fuel consumption, greenhouse gas emissions, air pollution, and road congestion associated with transporting products over long distances. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving materials and resources efficiency is to "use local or regional materials (extracted, processed and manufactured within 100 miles)" [1, p. 15]..

• Question 90:

  The Montreal Protocol banned the production of

  A. freon
  B. CFCs
  C. HCFCs
  D. ammonia
  B. CFCs

  ---

  The Montreal Protocol is an international treaty that aims to protect the ozone layer by phasing out the production and consumption of ozone-depleting substances (ODS). ODS are chemicals that contain chlorine or bromine, which can destroy the ozone molecules in the stratosphere. CFCs, or chlorofluorocarbons, are a group of ODS that were widely used in refrigeration, air conditioning, aerosols, and solvents..The Montreal Protocol banned the production of CFCs in 201012. Freon is a trade name for some CFCs and HCFCs, or hydrochlorofluorocarbons, which are also ODS but less harmful than CFCs..The Montreal Protocol also controls the production of HCFCs, which are being phased out gradually12..Ammonia is not an ODS and is not regulated by the Montreal Protocol1.
