LEED-Green-Associate Exam Dumps - USGBC Leadership in Energy and Environmental Design (LEED) Questions and Answers

The location valuation factor gives extra credit for products sourced within 100 miles (160 km) of the project site, promoting local economies and reduced transport emissions.

“Products extracted, manufactured, and purchased within 100 miles of the project site are valued at 200% of their cost to encourage support for local economies.”

SRI is a measure of a material's ability to reflect solar heat (reflectivity) and release absorbed heat (emissivity). This index helps evaluate materials for reducing the heat island effect under the Sustainable Sites category​​.

An existing LEED certified building located on a college campus is eligible for LEED for Building Operations and Maintenance; Existing Buildings (LEED O+M: EB). This rating system applies to existing buildings that are undergoing improvement work or little to no construction. It focuses on measuring and improving the performance of building operations and maintenance practices in areas such as energy efficiency, water conservation, waste management, indoor environmental quality, transportation, and occupant satisfaction. To be eligible for LEED O+M: EB, a project must meet certain minimum program requirements (MPRs), such as having a reasonable site boundary, being in a permanent location on existing land, being fully operational and occupied for at least one year prior to certification application, and complying with environmental laws and regulations. References: LEED certificationfor existing buildings and spaces6; Maintaining certification7; LEED v4: Building Operations + Maintenance Guide4

According to the LeadingGreen Study Guide:

"The first step in the certification process is the Project Registration. Projects can be registered on the GBCI website (www.gbci.org)... Before registration, the process begins with selecting the appropriate rating system using the 40/60 rule... "

Thus, selecting the correctrating systemis the initial key step before registration and documentation submission. The selection ensures alignment with the project type and its characteristics.

Acoustic Performance is a credit that aims to provide workspaces andclassrooms that promote occupants’ well-being, productivity, and communications through effective acoustic design1. This credit falls under the Indoor Environmental Quality category, which addresses the quality of the indoor environment as it relates to the health andcomfort of building occupants2. The Indoor Environmental Quality category has different credits for different LEED rating systems, such as LEED BD+C, LEED ID+C, LEED O+M, and LEED ND3. Acoustic Performance is one of the credits that is available for some of these rating systems, such as LEED BD+C: Schools, LEED ID+C: Commercial Interiors, and LEED O+M: Existing Buildings4.

LEED Rating Systems Overview

An alternative commuting incentive program is a strategy that can be used to encourage alternative transportation methods, such as public transit, carpooling, biking, or walking. An alternative commuting incentive program can provide benefits or rewards for the employees or tenants who use alternative transportation modes, such as subsidies, vouchers, discounts, prizes, recognition, or preferential parking. This strategy can help to achieve LEED Location and Transportation Credit: Alternative Transportation1 . References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide

LEED Building Design and Construction Homes and Multifamily Low-rise is a rating system that applies to single-family homes and multifamily buildings between one and three stories. This rating system covers the design and construction phases of residential projects that areintended for human occupancy12. Projects that have more than three stories are not eligible for this rating system, but may qualify for other LEED rating systems, such as LEED Building Design and Construction Multifamily Mid-rise, which applies to multifamily buildings between four and eight stories

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]

Carbon offsets are used to balance emissions by reducing or sequestering equivalent amounts of CO₂ elsewhere. LEED supports using carbon offsets to meet energy and atmosphere goals​​.

Covering duct work with plastic is a strategy for improving indoor environmental quality during construction. Covering duct work with plastic prevents dust, debris, and contaminants from entering the ducts and affecting the air quality of the building. This also reduces the need for cleaning and maintenance of the ducts after construction. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving indoor environmental quality is to “protect ducts during construction by sealing or covering with plastic” [1, p. 16]. References: LEED Green Associate Candidate Handbook, [Indoor Air Quality During Construction | U.S. Environmental Protection Agency]
