NEW QUESTION # 20
The intent of Water Efficiency Credit, Outdoor Water Use, is to minimize which of the following?
- A. Fertilizer use
- B. Heat island effect
- C. Wildlife habitat
- D. Building footprint
Answer: B
Explanation:
TheLEED for Homes Rating System (v4)includes theWater Efficiency (WE) Credit: Outdoor Water Use
, which aims to reduce irrigation water consumption through strategies like native plant selection and efficient irrigation systems.
According to theLEED Reference Guide for Homes Design and Construction (v4):
WE Credit: Outdoor Water Use (1-4 points)
The intent is to reduce outdoor water consumption for irrigation, thereby minimizing the environmental impact of water use and indirectly supporting other sustainability goals, such as reducing energy use associated with water delivery. While not directly targeting the heat island effect, efficient irrigation can contribute to cooler landscapes by supporting vegetation, unlike theSustainable Sites Credit: Heat Island Reduction, which directly addresses heat island mitigation.
Source: LEED Reference Guide for Homes Design and Construction, v4, Water Efficiency Credit: Outdoor Water Use, p. 98.
TheLEED v4.1 Residential BD+Crating system confirms:
WE Credit: Outdoor Water Use
The primary intent is to minimize outdoor water use for irrigation, which can also support vegetated surfaces that mitigate the heat island effect, though this is a secondary benefit.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
The correct answer isheat island effect(Option C), as reducing outdoor water use supports vegetated landscapes that help mitigate heat island effects, aligning with the credit's broader environmental goals. Note that the primary intent is water reduction, but among the options, heat island effect is the most relevant secondary benefit.

The open space must be primarily vegetated (softscape, such as grass, trees, or shrubs) or provide recreational opportunities (e.g., playgrounds, trails). Acceptable open spaces include parks, playgrounds, or nature preserves, but not water bodies or privately restricted areas.
Source: LEED Reference Guide for Homes Design and Construction, v4, Location and Transportation Credit: Site Selection, p. 55.
TheLEED v4.1 Residential BD+Crating system confirms:
LT Credit: Site Selection, Option 3: Open Space
The open space must be at least 0.75 acre (0.3 hectare), publicly accessible, and within 1/2 mile (0.8 km) of the project. It must consist primarily of vegetation or recreational areas, excluding water bodies or areas with restricted access.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
Evaluation of options:
* A. 1/2 mi. (0.8 km) of a 3/4 acre (0.3 hectare) cornfield: A cornfield is agricultural land, not a publicly accessible recreational or vegetated open space as defined by LEED, so it does not qualify.
* B. 3/4 mi. (1.2 km) of a publicly accessible park that is 3/4 acre (0.3 hectare) in size: The distance (3/4 mi.) exceeds the 1/2-mile (0.8 km) requirement, so it does not qualify.
* C. 1/2 mi. (0.8 km) of a pond surrounded by a 1/2 acre (0.2 hectare) walkway, and across the street from a 1/4 acre (0.1 hectare) publicly accessible park: The pond is excluded (water bodies do not qualify), and the walkway (0.2 hectare) and park (0.1 hectare) together total 0.3 hectare (0.75 acre), meeting the size requirement within 1/2 mile. Assuming the walkway is vegetated or recreational, this qualifies.
* D. 3/4 mi. (1.2 km) of a 1/4 acre (0.1 hectare) publicly accessible park, across the street from a 1/4 acre (0.1 hectare) lot which is private land open to the public: The distance (3/4 mi.) exceeds 1/2 mile, and the combined area (0.2 hectare) is below 0.3 hectare. Private land, even if publicly accessible, may not fully qualify without clear documentation.
The correct answer isOption C, as it meets the 1/2-mile distance and the combined 0.75-acre size requirement, assuming the walkway is vegetated or recreational.

NEW QUESTION # 29
A project team for a home in a small town is pursuing LEED certification. The home is designed with the following site characteristics:
* The lot is square.
* Three sides of the square lot border undeveloped land.
* The previous home covering 78% of the lot is deconstructed and the new LEED home will be built in its place.
* One full side of the square lot borders a home that was built 10 years before the LEED project.
Compliance with which of the following options, if any, will qualify the home for Location and Transportation Credit, Site Selection?
- A. Infill only
- B. Previously Developed only
- C. None, this home does not comply with Location and Transportation Credit, Site Selection
- D. Infill and Previously Developed
Answer: B
Explanation:
TheLEED for Homes Rating System (v4)includes theLocation and Transportation (LT) Credit: Site Selection, which awards points for building on infill or previously developed sites to minimize environmental impact.
According to theLEED Reference Guide for Homes Design and Construction (v4):
LT Credit: Site Selection (1-3 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.
TheLEED v4.1 Residential BD+Crating system confirms:
LT Credit: Site Selection
A site qualifies forOption 2: Previously Developedif 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 isPreviously Developed only(Option B), as the site meets the criteria for Option 2 but not Option 1.
Why not the other options?
