  • D. 2,500 ft² (232 m²) turf grass and 44,000 ft² (4,088 m²) native or adapted landscape

Answer: D

Explanation:
TheLEED for Homes Rating System (v4)includes theWater Efficiency (WE) Credit: Outdoor Water Use, which awards points based on the ratio of turf grass (high water use) to native or adapted plants (low water use) in the softscape to reduce irrigation needs.
According to theLEED Reference Guide for Homes Design and Construction (v4):
WE Credit: Outdoor Water Use (1-4 points)
Reduce outdoor water use by selecting native or adapted plants and limiting turf grass. Points are awarded based on the percentage of softscape area:
* < 5% turf grass and > 75% native or adapted plants: 4 points.The total softscape area is used to calculate the percentages of turf grass and native/adapted plants.Source: LEED Reference Guide for Homes Design and Construction, v4, Water Efficiency Credit: Outdoor Water Use, p. 98-99.
TheLEED v4.1 Residential BD+Crating system confirms:
WE Credit: Outdoor Water Use
Achieve 4 points by ensuring less than 5% of the softscape is turf grass and more than 75% is native or adapted plants, based on area calculations.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
Calculation for 4 points:
* Total softscape area: 57,500 ft².
* For 4 points:
* Turf grass: < 5% of 57,500 ft² = < 0.05 × 57,500 = < 2,875 ft².
* Native or adapted plants: > 75% of 57,500 ft² = > 0.75 × 57,500 = > 43,125 ft².
Evaluate options:
* A. 12,600 ft² turf grass and 40,000 ft² native or adapted:
* Turf grass: 12,600 / 57,500 = 21.91% (> 5%).
* Native: 40,000 / 57,500 = 69.57% (< 75%).
* Does not meet 4-point criteria (only qualifies for 1 point: < 60% turf, > 25% native).
* B. 11,500 ft² turf grass and 40,000 ft² native or adapted:
* Turf grass: 11,500 / 57,500 = 20% (> 5%).
* Native: 40,000 / 57,500 = 69.57% (< 75%).
* Does not meet 4-point criteria (qualifies for 2 points: < 40% turf, > 50% native).
* C. 2,500 ft² turf grass and 44,000 ft² native or adapted:
* Turf grass: 2,500 / 57,500 = 4.35% (< 5%).
* Native: 44,000 / 57,500 = 76.52% (> 75%).
* Meets 4-point criteria.
* D. 4,500 ft² turf grass and 44,000 ft² native or adapted:
* Turf grass: 4,500 / 57,500 = 7.83% (> 5%).
* Native: 44,000 / 57,500 = 76.52% (> 75%).
* Does not meet 4-point criteria (qualifies for 3 points: < 20% turf, > 75% native).
Answer Option C(2,500 ft² turf grass and 44,000 ft² native or adapted landscape) meets the requirements for 4 points.

NEW QUESTION # 53
In order for a LEED home to earn a point for Materials and Resources Credit, Environmentally Preferable Products, what minimum amount of insulation must be reclaimed or salvaged?

  • A. 70%
  • B. 100%
  • C. 80%
  • D. 90%

Answer: D

Explanation:
TheLEED for Homes Rating System (v4)awards points for theMaterials and Resources (MR) Credit:
Environmentally Preferable Productswhen materials, including insulation, meet sustainable criteria such as being reclaimed or salvaged. The credit calculates compliance based on the percentage of total material cost.
According to theLEED Reference Guide for Homes Design and Construction (v4):
MR Credit: Environmentally Preferable Products (1-4 points)
Use products that meet one or more of the following criteria for at least 25% (1 point), 50% (2 points), or 90% (3-4 points) by cost of the total materials:
* Reused or salvaged materials, such as reclaimed insulation.For specific material categories like insulation, at least 90% of the insulation (by cost) must be reclaimed, salvaged, or meet other environmentally preferable criteria to contribute significantly to the credit.Source: LEED Reference Guide for Homes Design and Construction, v4, Materials and Resources Credit: Environmentally Preferable Products, p. 160-161.
TheLEED v4.1 Residential BD+Crating system confirms:
MR Credit: Environmentally Preferable Products
To earn points, insulation must meet environmentally preferable criteria (e.g., 90% reclaimed or salvaged by cost) to contribute to the overall material cost percentage (25%, 50%, or 90%).
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
For insulation to contribute to earning a point under this credit, aminimum of 90%(by cost) must be reclaimed or salvaged (Option C), aligning with the credit's threshold for significant material contributions.
Why not the other options?

NEW QUESTION # 54
A home has a large shower compartment of 3,750 in² (2.4 m²) with dual 1.5 gpm (5.6 lpm) shower heads.
How should the flow rate be calculated?

  • A. Shower compartment size does not affect shower head flow rates for LEED compliance
  • B. The flow rates are added to total 3.0 gpm (11.2 lpm)
  • C. Multiple shower heads are not allowed
  • D. The flow rate is calculated as two separate compartments of 1.5 gpm (5.6 lpm)

Answer: C

Explanation:
TheLEED for Homes Rating System (v4)addresses shower compartments in theWater Efficiency (WE) Credit: Indoor Water Use, where the size and number of showerheads impact water use calculations.
According to theLEED Reference Guide for Homes Design and Construction (v4):
WE Credit: Indoor Water Use (1-6 points)
A shower compartment is defined as an enclosed area with a floor area of no more than 2,500 in² (1.6 m²), where all fixtures (e.g., multiple showerheads) count as a single fixture for water use calculations.
Compartments larger than 2,500 in² are considered multiple compartments, and multiple showerheads in such cases are not allowed for LEED compliance to ensure water efficiency.
Source: LEED Reference Guide for Homes Design and Construction, v4, Water Efficiency Credit: Indoor Water Use, p. 96.
TheLEED v4.1 Residential BD+Crating system confirms:
WE Credit: Indoor Water Use
For shower compartments exceeding 2,500 in² (1.6 m²), multiple showerheads are not permitted to maintain water efficiency goals. Each compartment must be treated separately if applicable, but large compartments cannot have multiple heads.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
The shower compartment is 3,750 in² (2.4 m²), exceeding the 2,500 in² limit. Therefore,multiple showerheads are not allowed(Option C), as LEED restricts multiple heads in oversized compartments to ensure water efficiency.
Why not the other options?
Reference: LEED Reference Guide for Homes Design and Construction, v4, WE Credit: Indoor Water Use, p.
96.
B). The flow rate is calculated as two separate compartments of 1.5 gpm (5.6 lpm): The compartment is one unit, and multiple heads are not allowed, not treated as separate compartments.Reference: LEED Reference Guide for Homes Design and Construction, v4, WE Credit: Indoor Water Use, p. 96.
D). Shower compartment size does not affect shower head flow rates for LEED compliance:
Compartment size directly affects whether multiple heads are allowed.Reference: LEED Reference Guide for Homes Design and Construction, v4, WE Credit: Indoor Water Use, p. 96.
TheLEED AP Homes Candidate Handbookemphasizes WE credits, including showerhead calculations, and references theLEED Reference Guide for Homes Design and Constructionas a key resource. The exam is based onLEED v4, ensuring the relevance of compartment size restrictions.

NEW QUESTION # 55
If the roof sheathing of a home is constructed of certified lumber approved for LEED, under what circumstances can points be earned?

  • A. If the certified content is greater than 45%
  • B. If the certified wood is sourced from a 600 mi. (966 km) radius
  • C. No points are earned because certified lumber is a prerequisite
  • D. If the certified content is greater than 90%

Answer: D

Explanation:
TheLEED for Homes Rating System (v4)awards points for theMaterials and Resources (MR) Credit:
Environmentally Preferable Productswhen using certified lumber, specifically Forest Stewardship Council (FSC)-certified wood, which contributes to the required percentage of material cost.
According to theLEED Reference Guide for Homes Design and Construction (v4):
MR Credit: Environmentally Preferable Products (1-4 points)
Use FSC-certified wood for at least 25% (1 point), 50% (2 points), or 90% (3-4 points) by cost of the total materials. For specific material categories like roof sheathing, at least 90% of the component (by cost) must be FSC-certified to significantly contribute to the credit.
Source: LEED Reference Guide for Homes Design and Construction, v4, Materials and Resources Credit:
Environmentally Preferable Products, p. 160-161.
TheLEED v4.1 Residential BD+Crating system confirms:
MR Credit: Environmentally Preferable Products
Points are awarded for FSC-certified lumber if it constitutes at least 90% of a specific component like roof sheathing (by cost) to meet higher point thresholds (e.g., 3-4 points). Certified lumber is not a prerequisite; it contributes to the credit.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
The correct answer isif the certified content is greater than 90%(Option B), as this ensures the roof sheathing significantly contributes to the credit's material cost threshold for points.
Why not the other options?
Reference: LEED Reference Guide for Homes Design and Construction, v4, MR Credit: Environmentally Preferable Products, p. 161.
C). If the certified wood is sourced from a 600 mi. (966 km) radius: Local sourcing (within 100 miles) is relevant forOption 1: Local Production, not FSC certification.Reference: LEED Reference Guide for Homes Design and Construction, v4, MR Credit: Environmentally Preferable Products, p. 160.

NEW QUESTION # 56
Energy losses due to supply duct leakage are most likely to occur when:

  • A. Ducts are located in unconditioned attics, basements, or exterior walls.
  • B. Duct layout includes multiple 90-degree bends on a single branch.
  • C. Ducts are located within conditioned envelope but joints are unsealed.
  • D. Interior wall cavities are used to conduct return air.

Answer: A

Explanation:
Duct leakage in HVAC systems can significantly increase energy losses, particularly when ducts are poorly sealed or located in areas that exacerbate the impact of leakage. This issue is addressed in theLEED for Homes Rating System (v4)under theEnergy and Atmosphere (EA)category, specifically in credits related to Heating and Cooling Distribution Systems.
According to theLEED Reference Guide for Homes Design and Construction (v4), the location of ducts plays a critical role in energy losses due to leakage:
EA Credit: Heating and Cooling Distribution Systems
To minimize energy losses, locate all heating and cooling ducts and air handlers within the conditioned envelope of the building. Ducts located in unconditioned spaces, such as attics, basements, or exterior walls, are more likely to lose energy due to leakage, as air escaping from ducts in these areas is lost to the outside or unconditioned zones, increasing heating and cooling loads.
Source: LEED Reference Guide for Homes Design and Construction, v4, Energy and Atmosphere Credit:
Heating and Cooling Distribution Systems, p. 126.
TheLEED v4.1 Residential BD+Crating system further clarifies this:
EA Credit: Optimize Energy Performance
Ducts located in unconditioned spaces (e.g., attics, unconditioned basements, or exterior walls) contribute to significant energy losses when leakage occurs, as conditioned air escapes to areas outside the thermal envelope. Sealing ducts and locating them within conditioned spaces are best practices to minimize losses.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
Ducts inunconditioned attics, basements, or exterior wallsare particularly problematic because any leakage results in conditioned air being lost to spaces that are not temperature-controlled, requiring the HVAC system to work harder to maintain indoor comfort. This scenario maximizes energy losses compared to ducts within the conditioned envelope.
Why not the other options?
Reference: LEED Reference Guide for Homes Design and Construction, v4, EA Credit: Heating and Cooling Distribution Systems, p. 127, which discusses return air strategies but not as a primary leakage concern.
B). Duct layout includes multiple 90-degree bends on a single branch: Multiple 90-degree bends increase airflow resistance, reducing system efficiency, but they do not directly cause duct leakage. Leakage is related to unsealed joints or poor duct construction, not the geometry of the duct layout.Reference: LEED Reference Guide for Homes Design and Construction, v4, EA Credit: Heating and Cooling Distribution Systems, p. 126, which prioritizes duct sealing over layout.
C). Ducts are located within conditioned envelope but joints are unsealed: While unsealed joints cause leakage, ducts within the conditioned envelope leak into spaces that are already temperature-controlled. This reduces the energy impact compared to leakage in unconditioned spaces, as the conditioned air remains within the thermal envelope.Reference: LEED Reference Guide for Homes Design and Construction, v4, EA Credit:
Heating and Cooling Distribution Systems, p. 126, which notes that ducts in conditioned spaces minimize energy loss from leakage.
TheLEED AP Homes Candidate Handbookconfirms that the exam tests knowledge of EA credits, including duct system design and energy performance, referencing theLEED Reference Guide for Homes Design and Constructionas a primary resource. The handbook ensures that the exam is based onLEED v4, aligning with the focus on duct location and sealing.

NEW QUESTION # 57
A shower stall was installed adjacent to an exterior wall prior to insulation installation. What is the impact to LEED for Homes certification?

  • A. The home cannot be LEED certified until the walls are insulated in compliance with the Thermal Enclosure Checklist
  • B. The overall R-value of the home's insulation must be increased to compensate for the deficit
  • C. The prescriptive path for Energy and Atmosphere cannot be used
  • D. The home energy model must include this feature so the HERS index score reflects it

Answer: A

Explanation:
TheLEED for Homes Rating System (v4)includes theEnergy and Atmosphere (EA) Prerequisite:
Minimum Energy Performance, which requires compliance with theThermal Enclosure System Checklist to ensure proper insulation and airtightness for energy efficiency.
According to theLEED Reference Guide for Homes Design and Construction (v4):
EA Prerequisite: Minimum Energy Performance
The project must comply with the Thermal Enclosure System Checklist, which requires that all exterior walls be fully insulated to meet or exceed specified R-values before other components (e.g., shower stalls) are installed. Insulation must be installed behind shower stalls or other fixtures adjacent to exterior walls to prevent thermal bridging and ensure compliance. Non-compliance with the checklist prevents certification until corrected.
Source: LEED Reference Guide for Homes Design and Construction, v4, Energy and Atmosphere Prerequisite: Minimum Energy Performance, p. 112.
TheLEED v4.1 Residential BD+Crating system confirms:
EA Prerequisite: Energy Performance
All exterior walls must be insulated in accordance with the Thermal Enclosure System Checklist. If components like shower stalls are installed before insulation, the home cannot be certified until the walls are properly insulated to meet the checklist requirements.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
The correct answer isthe home cannot be LEED certified until the walls are insulated in compliance with the Thermal Enclosure Checklist(Option D), as installing a shower stall before insulation violates the prerequisite's requirement for proper insulation installation.
Why not the other options?
Reference: LEED Reference Guide for Homes Design and Construction, v4, EA Prerequisite: Minimum Energy Performance, p. 112.
B). The home energy model must include this feature so the HERS index score reflects it: The HERS model assumes proper insulation; the issue is a construction error, not a modeling requirement.Reference:
LEED Reference Guide for Homes Design and Construction, v4, EA Prerequisite: Minimum Energy Performance, p. 112.
C). The overall R-value of the home's insulation must be increased to compensate for the deficit:
Increasing R-value elsewhere does not address the specific checklist requirement for insulation behind the shower stall.Reference: LEED Reference Guide for Homes Design and Construction, v4, EA Prerequisite:
Minimum Energy Performance, p. 112.
