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

The purpose of a life-cycle assessment (LCA) in LEED is to evaluate the potential environmental impacts of a building through its life-cycle, from the extraction of raw materials, to the manufacturing, transportation, installation, use, maintenance, and disposal or recycling of building materials and products1. LCA can help project teams to compare different design options and select the ones that minimize the environmental impacts of the building, such as global warming potential, ozone depletion potential, acidification potential, eutrophicationpotential, and smog formation potential12. LCA can also help projects earn points for the LEED v4 Building Design and Construction category under the Building Life-Cycle Impact Reductioncredit, which rewards projects for reducing the life-cycle impacts of their structure and enclosure by at least 10% compared to a baseline

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

Rainwater storage cisterns are components of a collected rainwater irrigation system that are most likely to make it cost prohibitive over a conventional system in a large site that has a short, intense rainy season and a long, dry season. A collected rainwater irrigation system is a system that collects, stores, and distributes rainwater for irrigation purposes. Rainwater storage cisterns are containers that store the collected rainwater until it is needed for irrigation. In a large site that has a short, intense rainy season and a long, dry season, the rainwater storage cisterns would need to be very large and durable to capture and store enough rainwater for the dry season. This would increase the initial cost and maintenance cost of the system compared to a conventional system that uses potable water or groundwater for irrigation1 . References: LEED v4 Green Associate Candidate Handbook1, EPA’s Rainwater Harvesting

The location valuation factor is a concept that applies to several credits under the Materials and Resources credit category in LEED v4. It means that if the purchased products or materials are extracted, manufactured, and purchased within 100 miles (160 kilometers) of the project, LEED will award the project in the credit calculations by valuing those products at 200% of their cost1. This is to incentivize the purchase of products that reduce transportation emissions and environmental impacts associated with long-distance shipping2.

According to the LEED credit library, the Energy and Atmosphere category for Building Design and Construction: New Construction and Major Renovation has 6 prerequisites and 11 credits, with a total of 33 possible points. The prerequisites are:

Fundamental Commissioning and Verification (required)

Minimum Energy Performance (required)

Building-Level Energy Metering (required)

Fundamental Refrigerant Management (required)

Construction Activity Pollution Prevention (required)

Advanced Energy Metering (required)

The credits are:

Enhanced Commissioning (2-6 points)

Optimize Energy Performance (1-18 points)

Advanced Energy Metering (1 point)

Demand Response (1-2 points)

Renewable Energy Production (1-3 points)

Enhanced Refrigerant Management (1 point)

Green Power and Carbon Offsets (1-2 points)

Per the LeadingGreen Study Guide:

“LEED points are awarded on a 100-point scale. Additionally, 10 bonus credits are available: six Innovation and four Regional Priority credits.”

This totals 110 maximum points.

Open grid pavement, also known as permeable pavement, allows water to drain through it, reducing runoff and recharging groundwater supplies. It also tends to be lighter in color than traditional asphalt, which means it absorbs less heat from sunlight. This helps to reduce the urban heat island effect, which is a phenomenon where urban areas are significantly warmer than their rural surroundings due to human activities. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
