LEED-AP-Homes Exam Dumps : LEED AP Homes (Residential) Exam

TheLEED for Homes Rating System (v4)outlines the requirements for theLocation and Transportation (LT) Credit: Site Selection, which includesOption 2: Infill Development. This credit encourages development on sites that minimize environmental impact by utilizing previously disturbed or developed land. For a site to qualify as infill development, a specific portion of its perimeter must border land that has been previously disturbed.

According to theLEED Reference Guide for Homes Design and Construction (v4), the requirement forOption 2: Infill Developmentis as follows:

Option 2. Infill Development (1 point)

Select a lot such that at least 75% of the perimeter of the project site immediately borders parcels that are previously developed or that have been graded or otherwise altered by direct human activities.

Source: LEED Reference Guide for Homes Design and Construction, v4, Location and Transportation Credit: Site Selection, p. 54.

This means that75% of the site’s perimetermust border previously disturbed land to meet the infill development criteria. The population of the town (10,000 in this case) does not directly affect the infill development requirement but may be relevant for other LT credits, such asAccess to Quality TransitorNeighborhood Pattern and Design, which consider community size or density. However, forSite Selection, Option 2, the focus is solely on the perimeter bordering previously disturbed land.

TheLEED v4.1 for Homesrating system aligns with this requirement, as it maintains the same infill development criteria for residential projects under the LT category:

LT Credit: Site Selection, Option 2. Infill Development

At least 75% of the project site’s perimeter must border previously developed or disturbed parcels.

TheLEED AP Homes Candidate Handbookconfirms that the exam tests knowledge of theLEED v4rating system, including the LT credits, and references theLEED Reference Guide for Homes Design and Constructionas a primary study resource. The handbook does not alter the technical requirements but emphasizes understanding credit intent and compliance paths, such as the infill development perimeter rule.

Why not the other options?

A. 25%: This is too low and does not meet the minimum threshold for infill development, which requires significant adjacency to previously disturbed land to ensure compact,sustainable development.

B. 50%: While closer, 50% still falls short of the 75% requirement, which is designed to prioritize sites fully integrated into existing developed areas.

D. 100%: Requiring 100% of the perimeter to border previously disturbed land is overly restrictive and not specified in the LEED v4 or v4.1 requirements.

TheLEED for Homes Rating System (v4)includesRegional Priority (RP) Creditsto incentivize projects to address environmental issues that are particularly critical in their specific geographic region.

According to theLEED Reference Guide for Homes Design and Construction (v4):

Regional Priority Credits (1–4 points)

The purpose of Regional Priority Credits is to enhance the ability of LEED project teams to address critical environmental issues specific to the project’s location, such as water scarcity or habitat restoration, by providing bonus points for achieving designated credits that align with regional priorities.

TheLEED v4.1 Residential BD+Crating system confirms:

Regional Priority Credits

RP Credits encourage projects to prioritize credits that address location-specific environmental challenges, offering up to four bonus points based on the project’s ZIP code or region.

The correct answer isto enhance the ability of LEED project teams to address critical environmental issues for the project’s location(Option D), as this reflects the intent of RP credits to focus on regional environmental priorities.

Why not the other options?

TheLEED for Homes Rating System (v4)addresses window performance in theEnergy and Atmosphere (EA) Credit: Windows, where a lower U-factor (thermal transmittance) improves energy efficiency by reducing heat loss or gain.

According to theLEED Reference Guide for Homes Design and Construction (v4):

EA Credit: Windows (1–3 points)

Use windows with a lower U-factor to reduce energy use by minimizing heat transfer through the glazing, improving the home’s thermal performance and reducing heating and cooling loads.

Source: LEED Reference Guide for Homes Design and Construction, v4, Energy and Atmosphere Credit: Windows, p. 122.

TheLEED v4.1 Residential BD+Crating system confirms:

EA Credit: Windows

A lower window U-factor reduces energy use by decreasing heat loss in winter and heat gain in summer, contributing to overall energy efficiency.

Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.

The correct answer isreduced energy use(Option B), as a lower U-factor directly improves the home’s energy performance by reducing thermal transfer.
