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

The LEED credit weightings are based on the impact categories defined and established by the USGBC, which is the organization that developed and administers the LEED rating system. The impact categories are aligned with the USGBC’s mission and vision of transforming the built environment to enhance environmental and human health. The impact categories are also informed by the Environmental Protection Agency’s (EPA) Tools for the Reduction and Assessment of Chemical and Other Environmental Impacts (TRACI) methodology, which provides a framework for assessing environmental impacts across different categories. References: LEED Link: Impact categories, section “LEED v4 impact categories”; LEED v4 Impact Category and Point Allocation Process Overview, page 1; LEED Green Associate Candidate Handbook, page 14

Integrative design is the term that encourages team members to collaborate throughout the process of design and construction to create synergistic solutions. Integrative design is an approach that considers the interrelationships among various building systems, environmental factors, and occupant needs, and seeks to optimize the performance, cost, and environmental benefits of the project. The LEED Green Associate Candidate Handbook states that one of the intents of the Integrative Process category is to “support high-performance, cost-effective project outcomes through an early analysis of the interrelationships among systems” [1, p. 12]. References: LEED Green Associate Candidate Handbook, [Integrative Design Process | Whole Building Design Guide]

Minimum acoustic performance is a prerequisite requirement that applies to LEED for Schools projects. The prerequisite aims to provide classrooms that facilitate better teacher-to-student and student-to-student communication through effective acoustic design. The prerequisite requires projects to meet the sound transmission class (STC) ratings for walls, floors, ceilings, doors, and windows; the background noise levels from HVAC systems; and the reverberation time for core learning spaces. By meeting the minimum acoustic performance, projects can improve the indoor environmental quality, enhance the learning outcomes, and reduce the health and stress impacts of noise. References: LEED v4 Reference Guide for Building Design and Construction, p. 545 1; [Acoustical Society of America website]

The LeadingGreen Study Guide defines carbon offsets as:

“Alternatively a project can purchase carbon offsets to reduce scope 2 emissions, as one carbon offset is equal to one carbon dioxide equivalent of greenhouse gases”.

Additionally, LEED recognizes carbon offsets as a method to:

“...compensate for emissions occurring elsewhere.”

Hence, the correct and verified answer isCarbon offsets.

Recycling is a strategy that can be used during the building process and after occupation to reduce waste. Recycling involves collecting, sorting, processing, and reusing or selling materials that would otherwise be discarded as waste. Recycling can save natural resources, reduce greenhouse gas emissions, create jobs, and lower disposal costs1 . Recycling can also help to achieveLEED credits in the Materials and Resources category by reducing the amount of construction and demolition waste generated by the project or by diverting waste from landfills or incinerators. References: LEED v4 Green Associate Candidate Handbook1, EPA’s Recycling Basics2, LEED v4 BD+C Reference Guide

LEED Building Design and Construction: Homes is the rating system that applies to single-family homes, low-rise multi-family homes, and mid-rise multi-family homes1. It includes the ability to reduce point thresholds for LEED certification levels based on building size, as smaller homes tend to have lower environmental impacts than larger homes2. The point thresholds are determined by the size of the house compared to the number of bedrooms1.

The project team’s strategy of using low-flow toilet fixtures and integrating non-potable water strategies for the building interior falls under the Water Efficiency category. The Water Efficiency category addresses the conservation and management of water resources in buildings and landscapes. Using low-flow toilet fixtures reduces the amount of potable waterused for flushing toilets, saving water and energy. Integrating non-potable water strategies for the building interior involves using alternative sources of water, such as rainwater, graywater, or reclaimed water, for non-potable purposes such as toilet flushing or irrigation, reducing the demand for potable water and wastewater generation. The other options are not categories that this strategy falls under. Innovation is a category that recognizes exemplary performance, innovative strategies, or pilot credits that are not covered by existing LEED credits. Sustainable Sites is a category that addresses the selection, development, and maintenance of project sites in ways that minimize environmental impacts and enhance human health and well-being. Optimized Process Water Use is not a LEED category or credit. References: LEED Green Associate Candidate Handbook, page 31; USGBC [Water Efficiency], page 1-2.
