USGBC LEED AP Homes (Residential) Exam Sample Questions (Q70-Q75):
NEW QUESTION # 70
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 overall R-value of the home's insulation must be increased to compensate for the deficit
- B. The prescriptive path for Energy and Atmosphere cannot be used
- C. The home energy model must include this feature so the HERS index score reflects it
- D. The home cannot be LEED certified until the walls are insulated in compliance with the Thermal Enclosure Checklist
Answer: D
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.
TheLEED AP Homes Candidate Handbookemphasizes EA prerequisites, including the Thermal Enclosure Checklist, and references theLEED Reference Guide for Homes Design and Constructionas a key resource. The exam is based onLEED v4, ensuring the relevance of insulation compliance.

NEW QUESTION # 71
Which of the following team members must attend the entire meeting to earn the Trades Training Credit?
- A. Site supervisor or superintendent
- B. Air sealing and insulation contractor
- C. Project architect
- D. Mechanical contractor
Answer: D
Explanation:
TheLEED for Homes Rating System (v4)includes theIntegrative Process (IP) Credit: Integrative Process, Option 2: Trades Training, which requires training for key construction trades to ensure proper implementation of green building strategies.
According to theLEED Reference Guide for Homes Design and Construction (v4):
IP Credit: Integrative Process, Option 2: Trades Training (1 point)
The mechanical contractor (responsible for HVAC systems) must attend the entire four-hour training session to ensure proper installation and operation of energy-efficient systems critical to LEED compliance. Other trades, such as air sealing and insulation contractors, are also encouraged but not explicitly required to attend the full session.
Source: LEED Reference Guide for Homes Design and Construction, v4, Integrative Process Credit:
Integrative Process, p. 45.
TheLEED v4.1 Residential BD+Crating system confirms:
IP Credit: Integrative Process, Option 2: Trades Training
The mechanical contractor, as a key trade responsible for energy-related systems, must participate fully in the four-hour training to meet the credit requirements, ensuring expertise in sustainable HVAC installation.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
The correct answer ismechanical contractor(Option B), as their full attendance is critical due to the importance of HVAC systems in achieving LEED energy goals.
Why not the other options?
* A. Project architect: Architects are part of the design team, not typically required for trades training.
* C. Site supervisor or superintendent: While important, they oversee general construction, not specific system installation.
Reference: LEED Reference Guide for Homes Design and Construction, v4, IP Credit: Integrative Process, p.
45.
TheLEED AP Homes Candidate Handbookemphasizes IP credits, including trades training, and references theLEED Reference Guide for Homes Design and Constructionas a key resource. The exam is based on LEED v4, ensuring the relevance of mechanical contractor attendance.

NEW QUESTION # 72
The use of native plants in place of conventional turf grass can increase which of the following?
- A. Native wildlife habitat
- B. Fertilizer demand
- C. Pesticide demand
- D. Irrigation demand
Answer: A
Explanation:
TheLEED for Homes Rating System (v4)encourages the use of native plants in theSustainable Sites (SS) Credit: Site Development - Protect or Restore HabitatandWater Efficiency (WE) Credit: Outdoor Water Useto enhance environmental benefits, including support for local ecosystems.
According to theLEED Reference Guide for Homes Design and Construction (v4):
SS Credit: Site Development - Protect or Restore Habitat (1-2 points)
Using native plants in place of conventional turf grass increases native wildlife habitat by providing food, shelter, and breeding areas for local species, supporting biodiversity.
Source: LEED Reference Guide for Homes Design and Construction, v4, Sustainable Sites Credit: Site Development - Protect or Restore Habitat, p. 74.
TheLEED v4.1 Residential BD+Crating system confirms:
SS Credit: Site Development - Protect or Restore Habitat
Native plants enhance native wildlife habitat by creating ecosystems that support local fauna, unlike turf grass, which offers minimal ecological value.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
The correct answer isnative wildlife habitat(Option B), as native plants are adapted to local conditions and support indigenous species, unlike turf grass.
Why not the other options?
Reference: LEED Reference Guide for Homes Design and Construction, v4, WE Credit: Outdoor Water Use, p. 98.
C). Irrigation demand: Native plants reduce irrigation needs compared to turf grass, which requires more water.Reference: LEED Reference Guide for Homes Design and Construction, v4, WE Credit: Outdoor Water Use, p. 98.
D). Pesticide demand: Native plants are more resistant to local pests, reducing pesticide use compared to turf grass.Reference: LEED Reference Guide for Homes Design and Construction, v4, SS Credit: Nontoxic Pest Control, p. 82.
TheLEED AP Homes Candidate Handbookemphasizes SS credits, including habitat restoration, and references theLEED Reference Guide for Homes Design and Constructionas a key resource. The exam is based onLEED v4, ensuring the relevance of native plants for wildlife.

NEW QUESTION # 73
A project team wants to earn credit for Location and Transportation Credit, Site Selection, Option 3: Open Space. A qualifying lot should be located within:
- A. 3/4 mi. (1.2 km) of a publicly accessible park that is 3/4 acre (0.3 hectare) in size
- B. 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
- 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 - D. 1/2 mi. (0.8 km) of a 3/4 acre (0.3 hectare) cornfield
Answer: C
Explanation:
TheLEED for Homes Rating System (v4)includes theLocation and Transportation (LT) Credit: Site Selection, Option 3: Open Space, which encourages projects to be located near publicly accessible open spaces to promote recreation and environmental benefits.
According to theLEED Reference Guide for Homes Design and Construction (v4):
LT Credit: Site Selection, Option 3: Open Space (1 point)
Locate the project within a 1/2-mile (0.8-kilometer) walking distance of a publicly accessible open space that is at least 0.75 acre (0.3 hectare) in size. 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 # 74
As a prerequisite for Education of the Homeowner, Tenant, or Building Manager, the operations and maintenance manual must include which of the following?
- A. Product manuals for installed equipment
- B. A set of building plans
- C. A list of local services including a map
- D. Chemical analysis of domestic water supply
Answer: A
Explanation:
The question references an "Energy and Atmosphere Prerequisite" for homeowner education, which appears to be a misnomer, as theLEED for Homes Rating System (v4)includes this requirement under the Innovation (IN) Prerequisite: Education of the Homeowner, Tenant, or Building Manager. This prerequisite ensures occupants are educated on the home's sustainable features and maintenance needs.

TheLEED v4.1 Residential BD+Crating system confirms:
IN Prerequisite: Education of the Homeowner or Tenant
The operations and maintenance manual must include product manuals for all installed equipment to ensure proper use and upkeep of sustainable systems.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
The correct answer isproduct manuals for installed equipment(Option C), as these are required in the operations and maintenance manual to support homeowner education.
Why not the other options?
Reference: LEED Reference Guide for Homes Design and Construction, v4, IN Prerequisite: Education of the Homeowner, Tenant, or Building Manager, p. 188.
B). A list of local services including a map: This is relevant toLT Credit: Community Resources and Services, not the homeowner education prerequisite.Reference: LEED Reference Guide for Homes Design and Construction, v4, LT Credit: Community Resources and Services, p. 56.
D). Chemical analysis of domestic water supply: Water quality analysis may be relevant for health but is not required in the operations and maintenance manual.Reference: LEED Reference Guide for Homes Design and Construction, v4, IN Prerequisite: Education of the Homeowner, Tenant, or Building Manager, p. 188.
