LEED-AP-Homes Exam Questions & Answers

The LEED for Homes Rating System (v4) emphasizes site evaluation for credits like Location and Transportation (LT) Credit: Site Selection, which includes assessing past development activity to determine eligibility for options such as infill development or avoiding sensitive land.

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

LT Credit: Site Selection (1--3 points)

Evaluate the site to determine if it meets criteria for infill development (e.g., at least 75% of the perimeter borders previously disturbed land) or avoids environmentally sensitive areas (e.g., prime farmland, floodplains). A LEED AP can assist by assessing past development activity to confirm eligibility for credits like Option 2: Infill Development.

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 key step in site evaluation is determining whether the site has been previously developed or disturbed, which supports credits for infill or brownfield redevelopment.

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

The correct answer is evaluate the site for any past development activity (Option B), as this directly supports achieving LT Credit: Site Selection by confirming eligibility for infill development or other site-related credits.

Why not the other options?

A . Calculate the acreage of public parking adjacent to the proposed site: Parking acreage is not a direct requirement for LT credits; proximity to services or transit is more relevant.

C . Evaluate the potential for site pollution from adjoining properties: While pollution assessment may be relevant for brownfield sites, it is not a primary focus of LT credits for single-family homes.

D . Determine if the location is in the city limits: City limits are not a specific criterion for LT credits; proximity to services or site characteristics are prioritized.

The LEED AP Homes Candidate Handbook emphasizes the role of the LEED AP in site evaluation for LT credits and references the LEED Reference Guide for Homes Design and Construction as a key resource. The exam is based on LEED v4, ensuring the relevance of past development assessment.

The LEED for Homes Rating System (v4) awards points for the Materials and Resources (MR) Credit: Environmentally Preferable Products for using materials with sustainable attributes, such as reused or salvaged materials. In a gut rehab project, maintaining existing exterior wall and floor framing qualifies these components as reused materials.

According to the LEED 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%, 50%, or 90% (by cost) of the total materials:

Reused or salvaged materials: Materials that are reclaimed from the same or another project, such as existing framing maintained in a gut rehab.

In gut rehab projects, existing structural components (e.g., wall and floor framing) that are reused in place qualify as reclaimed materials.

Source: LEED Reference Guide for Homes Design and Construction, v4, Materials and Resources Credit: Environmentally Preferable Products, p. 160.

The LEED v4.1 Residential BD+C rating system confirms:

MR Credit: Environmentally Preferable Products

Reclaimed materials, such as existing framing reused in gut rehab projects, contribute to the percentage of environmentally preferable products based on their cost.

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

The term reclaimed (Option B) is used in LEED to describe materials that are reused or salvaged, such as existing framing kept in place during a gut rehab. This reduces the demand for new materials and aligns with the credit's intent.

Why not the other options?

A . Recycled: Recycled materials contain pre- or post-consumer recycled content (e.g., fly ash in concrete). Existing framing is not recycled but reused in its original form, so it does not qualify as recycled.

C . Refurbished: Refurbished materials are restored or repaired for reuse (e.g., refinished doors). Framing maintained in place is not refurbished but simply reused, so this term does not apply.

D . Restructured: This term is not used in LEED and does not describe the reuse of existing framing.

The LEED AP Homes Candidate Handbook emphasizes MR credits, including Environmentally Preferable Products, and references the LEED Reference Guide for Homes Design and Construction as a key resource. The exam is based on LEED v4, ensuring the relevance of the term ''reclaimed.''

The LEED for Homes Rating System (v4) includes the Energy and Atmosphere (EA) Credit: Renewable Energy, which awards points based on the percentage of annual energy use offset by on-site renewable energy systems, such as photovoltaic (PV) systems.

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

EA Credit: Renewable Energy (1--4 points)

Install on-site renewable energy systems to offset a percentage of the home's annual energy use. Points are awarded as follows:

1 point: 0.5 kW or 5% of annual energy use.

2 points: 1.0 kW or 10% of annual energy use.

3 points: 1.5 kW or 15% of annual energy use.

4 points: 2.0 kW or 20% of annual energy use.

The kW values are for photovoltaic systems and assume typical production rates (e.g., 1 kW 1,500 kWh/year).

Source: LEED Reference Guide for Homes Design and Construction, v4, Energy and Atmosphere Credit: Renewable Energy, p. 138.

The LEED v4.1 Residential BD+C rating system confirms:

EA Credit: Renewable Energy

Points are awarded based on the installed capacity of PV systems (e.g., 2.0 kW for 4 points) or the percentage of energy offset, whichever is higher. A 2000 kWh system (approximately 2.0 kW) qualifies for 4 points.

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

The question states a 1000 kWh PV system earns 2 points, corresponding to approximately 1.0 kW (assuming 1 kW 1,500 kWh/year). A 2000 kWh system is approximately 2.0 kW (2000 1500 1.33 kW, but conservatively aligned with the 2.0 kW threshold in LEED), which earns 4 points (Option D).

Why not the other options?

A . One point: This corresponds to 0.5 kW, far below a 2000 kWh system.

B . Two points: This is the baseline for a 1000 kWh (1.0 kW) system, not 2000 kWh.

C . Three points: This requires 1.5 kW, which is less than the 2.0 kW equivalent of a 2000 kWh system.

The LEED AP Homes Candidate Handbook emphasizes EA credits, including renewable energy, and references the LEED Reference Guide for Homes Design and Construction as a key resource. The exam is based on LEED v4, ensuring the relevance of PV system sizing.

The LEED v4.1 Residential BD+C rating system confirms:

IN Prerequisite: Education of the Homeowner or Tenant

An operations and maintenance manual must be provided to occupants, detailing the function, operation, and maintenance of sustainable systems and equipment in the home.

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

The correct answer is operations and maintenance manual (Option B), as this is the required written material to comply with the prerequisite.

Why not the other options?

A . ASHRAE Standard 90.1-2006: This standard applies to commercial buildings, not residential, and is not required for homeowner education.

C . 1990 Americans with Disabilities Act (ADA) guidelines: These are unrelated to LEED homeowner education requirements.

D . Environmental Protection Agency (EPA) for Homes guidelines: While ENERGY STAR guidelines may be relevant, they are not required written materials for this prerequisite.
