USGBC Updated LEED-Green-Associate Exam Questions and Answers by ferne

A salvaged wood door from another site qualifies under the Materials and Resources sustainable criteria of materials reuse. Materials reuse is the practice of using existing materials or products for new purposes without altering their form or composition. Materials reuse reduces the demand for virgin materials, saves energy and resources, and prevents waste generation. The other options are not applicable to a salvaged wood door from another site. Certified wood is wood that has been harvested from forests that are managed in an environmentally responsible, socially beneficial, and economically viable manner according to the standards of an accredited certification system such as the Forest Stewardship Council (FSC). Bio-based materials are materials that are derived from plants or animals, such as bamboo, cork, wool, or cotton. Waste diversion is the practice of diverting waste from landfills or incinerators by recycling, reusing, salvaging, or donating materials. References: LEED Green Associate Candidate Handbook, page 28; USGBC, [Materials and Resources], page 4.

Social responsibility is one of the factors that contribute to the triple bottom line. The triple bottom line is a framework that measures the performance of an organization or a project based on three dimensions: environmental, social, and economic. Social responsibility refers to the ethical obligation of an organization or a project to consider the impacts of its decisions and actions on society and stakeholders, such as employees, customers, communities, and future generations. The other options are not factors that contribute to the triple bottom line. Global security is a broad concept that encompasses various aspects of international relations, such as peace, human rights, justice, and cooperation. Project balance sheet is a financial statement that summarizes the assets, liabilities, and equity of a project at a given point in time. Green metrics and verification are tools and methods that quantify and validate the environmental performance of a project or a product. References: LEED Green Associate Candidate Handbook, page 31; USGBC [LEED v4 Impact Category: Triple Bottom Line], page 1.

Creating a climate-smart forest by clearing invasive species to enhance biodiversity is the best answer because regenerative site stewardship goes beyond reducing harm and actively improves ecological function. LEED Sustainable Sites encourages protection and restoration of habitat, conservation of natural features, native or adaptive planting, and support for biodiversity. Removing invasive species helps restore ecological balance because invasive plants can displace native species, reduce habitat quality, and weaken ecosystem services. A community garden can support social and local food goals, and permeable pavement can help rainwater management, but these options do not as directly describe regenerative ecological restoration. Expanding impervious hardscape is incorrect because it increases runoff, heat island effects, and habitat disturbance.

LEED promotes compact, transit-rich locations:

“Locating a project in an area that supports walking, biking, and mass transit... will result in lower GHG emissions from reduced car travel.”

Urban centers offer the best access to alternative transport and reduce reliance on fossil fuels.
