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

LEED states:

“Refrigerants have ozone depletion potential (ODP) and global warming potential (GWP)... Projects should select refrigerants with low values of both.”

This aligns with the credit “Fundamental Refrigerant Management” in LEED v4.

The Sustainable Sites (SS) category addresses the site selection, design, construction, and operation of a project, as well as its impacts on the natural and built environment. One of the goals of this category is to reduce light pollution and discourage the development of previously undeveloped land. Light pollution is the excessive or inappropriate use of artificial lighting that can have adverse effects on human health, wildlife, ecosystems, and astronomy. Previously undeveloped land is land that has not been graded, cleared, or built upon prior to the current project and remains in a natural state. Developingpreviouslyundeveloped land can result in habitat loss, soil erosion, stormwater runoff, and increased infrastructure costs13. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide3

Placing indoor equipment in acoustically insulated closet areas is the correct answer because it reduces background noise from mechanical and operational equipment. In educational spaces, acoustical performance is especially important because students must clearly hear teachers and communicate with classmates. LEED for Schools includes acoustical requirements to support learning, reduce distraction, and improve speech intelligibility. White noise machines may mask some distractions, but they can also add background noise and do not solve the source problem. Increasing room size alone does not necessarily reduce reverberation or equipment noise. Hard surfaces often reflect sound and can worsen acoustics. Better strategies include isolating noisy equipment, using absorptive finishes, controlling HVAC noise, and designing spaces to meet appropriate acoustic standards.

EPA’s ENERGY STAR Portfolio Manager is a no-cost, interactive energy management tool that allows you to securely track and assess energy and water consumption across your building portfolio12. You can use Portfolio Manager to benchmark your building’s performance, set investment priorities, verify savings, and apply for ENERGY STAR certification23. Portfolio Manager does not measure embodied energy, which is the total amount of energy required to produce, transport, and install building materials.
