Explanation
LEED certification is awarded based on the number of points a project earns across several categories of green building performance. The range of points required to maintain Gold level of LEED certification is 60-79, out of a possible 110 points. The other levels of LEED certification are: Certified (40-49 points), Silver (50-59 points), and Platinum (80 or more points)13.

This scenario would potentially help a project earn the most LEED points because it aligns with the goals and criteria of the LEED v4 Location and Transportation category, which aims to reduce the environmental and human health impacts of transportation and promote sustainable site selection1. By renovating a large building in a diverse, walkable business district and central transit connectivity, the project can:
Preserve existing buildings and reduce the demand for new construction materials and land development2 Enhance the livability, vitality, and diversity of the urban area and support mixed-use development3 Provide access to quality transit options and reduce the reliance on private vehicles, lower greenhouse gas emissions, and encourage alternative modes of travel4 Support walkability and connectivity to various amenities and services within walking distance5 Avoid locating on sensitive lands or prime farmland that could support open space, habitat, or agriculture These strategies can help the project earn points for various credits under the Location and Transportation category, such as LEED for Neighborhood Development Location, Surrounding Density and Diverse Uses, Access to Quality Transit, Bicycle Facilities, Reduced Parking Footprint, High Priority Site and Equitable Development1.

Explanation
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 workers and 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

LEED certification is awarded based on the number of points a project earns across several categories of green building performance. The range of points required to achieve LEED Silver is 50-59, out of a possible
110 points. The other levels of LEED certification are: Certified (40-49 points), Gold (60-79 points), and Platinum (80 or more points)12. Therefore, if a project initially has 34 credit points,it would need 20 additional points to reach the minimum threshold for LEED Silver.
