An existing home in a gut rehab LEED for Homes project reclaims all of the original framing. An addition is built with 90% FSC-certified wood. Which credit, if any, under Materials and Resources, will be earned?
The LEED for Homes Rating System (v4) includes several credits under the Materials and Resources (MR) category that encourage sustainable material use, including reclaimed materials and certified wood. The scenario describes a gut rehab project that reclaims all original framing and builds an addition with 90% FSC-certified wood. We need to determine which MR credit applies.
According to the LEED Reference Guide for Homes Design and Construction (v4), the MR Credit: Environmentally Preferable Products rewards the use of materials that have environmentally beneficial attributes, such as reclaimed materials and FSC (Forest Stewardship Council)-certified wood:
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 in the project:
Reused or salvaged materials: Materials that are reclaimed from the same or another project.
FSC-certified wood: Wood products certified by the Forest Stewardship Council for sustainable forestry practices.
For gut rehab projects, reclaimed framing materials and FSC-certified wood in additions contribute to the percentage of environmentally preferable products.
Source: LEED Reference Guide for Homes Design and Construction, v4, Materials and Resources Credit: Environmentally Preferable Products, p. 160.
In this case:
Reclaimed framing: The gut rehab reclaims 100% of the original framing, which qualifies as reused or salvaged materials under the credit.
FSC-certified wood: The addition uses 90% FSC-certified wood, which also qualifies as an environmentally preferable product.
The LEED v4.1 Residential BD+C rating system aligns with this approach:
MR Credit: Environmentally Preferable Products
Projects earn points by using products that are salvaged, recycled, or FSC-certified for at least 25%, 50%, or 90% of the material cost. For renovations, salvaged framing and certified wood in additions are eligible.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
Since the project uses both reclaimed framing (100% of the original) and 90% FSC-certified wood in the addition, it meets the criteria for Environmentally Preferable Products, provided the combined material cost meets the 25%, 50%, or 90% thresholds. The high percentage of FSC-certified wood and full reclamation of framing make it likely to achieve at least one point.
Why not the other options?
A . Construction Waste Management: This credit focuses on diverting construction and demolition waste from landfills through recycling or reuse (e.g., 50% or 75% diversion rates). While reclaimed framing reduces waste, the credit is about waste management processes, not the use of reclaimed materials in the building.
B . No credit will be awarded: This is incorrect, as the use of reclaimed framing and FSC-certified wood directly contributes to the Environmentally Preferable Products credit.
C . Material-Efficient Framing: This credit rewards practices that reduce framing material use, such as advanced framing techniques (e.g., 24-inch on-center stud spacing) or minimizing waste during design. Reclaiming framing or using FSC-certified wood does not address framing efficiency.
The LEED AP Homes Candidate Handbook confirms that the exam tests MR credits, including Environmentally Preferable Products, and references the LEED Reference Guide for Homes Design and Construction as a primary resource. The exam is based on LEED v4, ensuring the relevance of this credit.

Which of the following strategies contributes to achieving Sustainable Sites Credit, Rainwater Management?
The LEED for Homes Rating System (v4) includes the Sustainable Sites (SS) Credit: Rainwater Management, which aims to reduce stormwater runoff and its environmental impacts through on-site management strategies.
According to the LEED Reference Guide for Homes Design and Construction (v4):
SS Credit: Rainwater Management (1--3 points)
Manage stormwater runoff through strategies such as directing runoff to permanent infiltration features (e.g., rain gardens, permeable paving, or bioswales) to reduce the volume and rate of runoff entering storm sewers.
Source: LEED Reference Guide for Homes Design and Construction, v4, Sustainable Sites Credit: Rainwater Management, p. 76.
The LEED v4.1 Residential BD+C rating system confirms:
SS Credit: Rainwater Management
Directing rainwater runoff to permanent infiltration features, such as rain gardens or infiltration trenches, contributes to credit achievement by promoting on-site retention and reducing stormwater discharge.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
The correct answer is direct rainwater runoff toward an appropriate permanent infiltration feature (Option B), as this directly reduces runoff volume, aligning with the credit's intent.
Why not the other options?
A . Use drought-resistant vegetation in all planting areas: This is relevant to WE Credit: Outdoor Water Use, not rainwater management.
C . Install a graywater collection system with filtration for irrigation and non-potable use: Graywater systems are addressed in WE Credit: Indoor Water Use or WE Credit: Outdoor Water Use, not stormwater management.
D . Provide filtration of the stormwater runoff before discharging into the city storm system: Filtration improves water quality but does not reduce runoff volume, which is the primary goal of the Rainwater Management credit.

According to the LEED Reference Guide for Homes Design and Construction (v4):
SS Credit: Nontoxic Pest Control (1 point)
Use treated wood (e.g., pressure-treated or borate-treated) for all wood-to-concrete connections to prevent termite damage in a way that minimizes environmental impact compared to broad chemical treatments. This is considered a nontoxic or low-toxicity strategy for pest control.
Source: LEED Reference Guide for Homes Design and Construction, v4, Sustainable Sites Credit: Nontoxic Pest Control, p. 82.
The LEED v4.1 Residential BD+C rating system confirms:
SS Credit: Nontoxic Pest Control
Using treated wood for wood-to-concrete connections is an acceptable strategy to earn points by preventing pest access while minimizing chemical use.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via LEED Online.
The correct answer is use treated wood for all wood-to-concrete connections (Option C), as this is a recognized nontoxic pest control strategy for the credit.
Why not the other options?
A . Treat all material with a borate product: Treating all materials is overly broad and may not be considered nontoxic due to excessive chemical use.
B . Install landscaping within 24 in. (0.6 m) of home: This may increase pest access, contradicting the credit's intent.
D . Treat all wood framing with a borate product to a minimum of 3 ft. (0.9 m) below foundation: This is not a standard strategy and may involve excessive chemical use, not aligning with nontoxic goals.
