Explanation:
The LEED for Homes Rating System (v4) includes the Location and Transportation (LT) Credit: Site Selection, which awards points for building on infill or previously developed sites to minimize environmental impact.
According to the LEED Reference Guide for Homes Design and Construction (v4):
LT Credit: Site Selection (1C3 points)
Option 1: Infill: At least 75% of the lot’s perimeter must border previously developed parcels (e.g., existing buildings or infrastructure).
Option 2: Previously Developed: The lot must have been previously altered by construction (e.g., a prior home covering a significant portion of the site) before the LEED project.
A site with a previous home covering 78% of the lot qualifies as previously developed, but if only one side (25% of a square lot’s perimeter) borders a developed parcel, it does not meet the infill requirement.
Source: LEED Reference Guide for Homes Design and Construction, v4, Location and Transportation
Credit: Site Selection, p. 54.
The LEED v4.1 Residential BD+C rating system confirms:
LT Credit: Site Selection
A site qualifies for Option 2: Previously Developed if it was previously altered (e.g., a home covering 78% of the lot). Infill requires 75% of the perimeter to border developed land, which a square lot with only one developed side (25%) does not meet.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
Evaluation:
Infill: The lot is square, with one side (25% of the perimeter) bordering a developed home. This does not meet the 75% perimeter requirement for infill.
Previously Developed: The previous home covered 78% of the lot, qualifying it as previously developed.
The correct answer is Previously Developed only (Option B), as the site meets the criteria for Option 2 but not Option 1.
Why not the other options?

The introduction of outdoor air improves indoor air quality primarily through dilution (Option A), as it mixes with indoor air to reduce pollutant concentrations.
Why not the other options?
B. Source control: This involves selecting low-emission materials or isolating pollutant sources, not introducing outdoor air.
Reference: LEED Reference Guide for Homes Design and Construction, v4, EQ Credit: Contaminant Control, p. 148.
C. Pressurization: Pressurization controls air movement (e.g., to prevent infiltration), not the primary mechanism for improving air quality via outdoor air.
Reference: LEED Reference Guide for Homes Design and Construction, v4, EQ Credit: Enhanced Ventilation, p. 146.
D. Source removal: This involves physically removing pollutant sources, not a function of outdoor air introduction.

Explanation:
The LEED for Homes Rating System (v4) encourages passive solar design strategies in the Energy and Atmosphere (EA) category, particularly in EA Credit: Optimize Energy Performance or EA Prerequisite: Minimum Energy Performance, to maximize energy efficiency through site and building design.
According to the LEED Reference Guide for Homes Design and Construction (v4):
EA Credit: Optimize Energy Performance
The first step in solar home design is to orient the building to maximize solar exposure for passive heating, daylighting, and potential active solar systems. Proper orientation (e.g., south-facing in the Northern Hemisphere) optimizes energy performance before other strategies like window selection or shading.
