  ---

  One type of construction pollution that can be reduced by prevention activities is airborne dust generation. Airborne dust can be generated by various construction activities, such as excavation, demolition, grading, hauling, and vehicle traffic. Airborne dust can have negative impacts on the air quality, human health, and climate. Airborne dust can contribute to respiratory problems, allergies, asthma, and eye irritation for workersand nearby residents. Airborne dust can also reduce the visibility, increase the risk of accidents, and damage the equipment and materials..Airborne dust can also affect the climate by absorbing or reflecting solar radiation, altering the cloud formation and precipitation patterns, and influencing the carbon cycle1. Some of the prevention activities that can reduce airborne dust generation during construction are12: Covering or wetting the exposed soil and stockpiles Using water sprays or misters to suppress the dust Installing wind fences or barriers around the site Applying mulch, straw, or vegetation to stabilize the soil Sweeping or vacuuming the paved areas and roads Limiting the speed and frequency of vehicles Using low-emission or electric vehicles and equipment Implementing a dust control plan and monitoring the dust levels

• Question 4:

  A. building materials from extraction to reuse
  B. building materials from extraction to disposal
  C. building materials from installation to disposal
  D. building materials from installation to recycling
  A. building materials from extraction to reuse

  ---

  The cradle-to-cradle approach to sustainable materials evaluates building materials from extraction to reuse, which means that the materials are considered as part of a continuous cycle of use and regeneration, rather than a linear process of consumption and disposal. The cradle-to-cradle approach aims to eliminate waste and pollution, conserve resources and energy, and create positive impacts for the environment and human health..The cradle-to-cradle approach is based on the principles of ecoeffectiveness, which include designing products and systems that are safe and healthy for humans and nature, using renewable energy and clean water, celebrating diversity and creativity, and respecting social and environmental justice12..The cradle-to-cradle approach is also recognized and encouraged by LEED v4, which includes a credit for using products that have achieved Cradle to Cradle certification34.

• Question 5:

  A new project is being built adjacent to a park with a 1/8 mi. (0.20 km) trail leading to an urban business district, which includes several retail shops and restaurants. This project qualifies for Location and Transportation Credits by

  A. maintaining open space
  B. reducing heat island effect
  C. providing pedestrian access
  D. encouraging physical activity
  C. providing pedestrian access

  ---

  The Location and Transportation (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 LT Credit: Surrounding Density and Diverse Uses, which rewards projects that are located in areas with high density and a variety of land uses, such as retail, residential, and civic facilities. This can reduce vehicle miles traveled, greenhouse gas emissions, and infrastructure costs, as well as promote walkability, livability, and social interaction. A new project that is built adjacent to a park with a trail leading to an urban business district qualifies for this credit by providing pedestrian access to diverse uses within a 1/2 mi..(0.80 km) walking distance1...

• Question 6:

  An owner is looking to update the interior materials of the office while promoting a healthier indoor work environment using LEED strategies. During the materials specification, which of the following strategies can the owner take in order to achieve this goal?

  A. Specify salvaged materials
  B. Specify low-cost materials
  C. Specify low-emitting materials
  D. Specify high solar reflectance materials
  C. Specify low-emitting materials

  ---

  An owner who wants to update the interior materials of the office while promoting a healthier indoor work environment using LEED strategies can specify low-emitting materials as one of the strategies to achieve this goal. Low-emitting materials are materials that have low or no emissions of volatile organic compounds (VOCs) or other pollutants into the indoor air. VOCsare organic chemicals that can evaporate or vaporize at room temperature and can adversely affect the indoor air quality (IAQ) of a building and the health, comfort, and productivity of the occupants. Some sources of VOCs in buildings are paints, coatings, adhesives, sealants, flooring, furniture, and cleaning products..Specifying low-emitting materials can reduce the exposure and risk of VOCs for the occupants and improve IAQ..

• Question 9:

  Lighting controls are typically installed in buildings in order to A. provide a uniform light level across every space in a building

  B. prevent building occupants from making changes to the light levels

  C. improve occupant comfort and save energy throughout the building

  D. filter glare produced by overhead fixtures and prevent ultraviolet radiation from reaching building occupants

  Correct Answer. C
  C

  ---

  Lighting controls are devices or systems that can regulate the amount and quality of light in a space according to various factors, such as user preferences, natural light availability, occupancy, and time of day. By doing so, lighting controls can improve occupant comfort and save energy throughout the building. Lighting controls can enhance the visual comfort, well-being, and productivity of the occupants by providing them with appropriate and adjustable light levels for different tasks and moods. Lighting

  controls can also reduce the energy consumption and environmental impact of the lighting system by avoiding unnecessary or excessive lighting, which can waste electricity, generate heat, and contribute to greenhouse gas emissions. Lighting controls are an essential component of green building design and certification, such as LEED v4, which has adopted ASHRAE Standard 90.1-2010 as the baseline for energy performance and lighting requirements. LEED v4 also recognizes and rewards various

  lighting control strategies, such as automatic shutoff, light-level reduction, daylight harvesting, exterior lighting control, and plug-load control..
