LEED-Green-Associate Exam Dumps - LEED Green Associate GAFRE Exam (LEED GA)

A brownfield is a property that has been previously used for industrial or commercial purposes and may be contaminated by hazardous substances, pollutants, or contaminants12. Brownfields can pose environmental and health risks and require remediation before redevelopment3. Examples of brownfields include abandoned factories, gas stations, dry cleaners, etc

This formula is used to calculate the percentage of restoration area for the LEED v4 credit SSc2: Protect or Restore Habitat1. The restoration area is the portion of the site that is restored with native or adapted vegetation, and the total previously disturbed site area is the area that was altered by human activity before the project2.

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. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

LEED for Building Operations and Maintenance (O+M) is the rating system that applies to existing buildings and interior spaces that have been fully operational and occupied for at least one year1. It focuses on performance-oriented sustainable strategies and outcomes, such as energy efficiency, water conservation, waste management, indoor environmental quality, and transportation2. LEED O+M can help existing buildings reduce their environmental impacts and improve their operations1.

Regional priority credits are bonus points that are awarded to projects that achieve credits that address geographically specific environmental, social equity and public health priorities. These credits are not new LEED credits, but instead are existing credits that USGBC regional councils and chapters have designated as being particularly important for their areas. The goal of regional priority credits is to incentivize project teams to address the most critical and relevant environmental issues in their regions, such as water scarcity, air quality, habitat loss, or social equity12. Regional priority credits are based on the project’s geolocation (latitude and longitude coordinates), which can be entered and confirmed during project registration in LEED Online2. Each project can earn up to four regional priority bonus points, one for each regional priority credit achieved3.

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

LEED credits are weighted based on their potential environmental impacts and human benefits. Those that most directly address these areas are given greater weight in the scoring system. This approach is intended to prioritize actions that have the greatest positive impact on critical environmental issues such as climate change, water resources, biodiversity, air pollution, and human health. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
