TheLEED for Homes Rating System (v4)includesRegional Priority (RP) Credits, which provide bonus points for achieving existing credits identified as environmentally significant for a project's region. For credits with multiple thresholds, exemplary performance can earn additional points.
According to theLEED Reference Guide for Homes Design and Construction (v4):
Regional Priority Credits (1-4 points)
Regional Priority Credits are awarded for achieving designated credits that address location-specific environmental priorities. For credits with multiple thresholds (e.g., Water Efficiency Credit: Outdoor Water Use), an additional bonus point is awarded when the maximum threshold has been exceeded, demonstrating exemplary performance.

TheLEED v4.1 Residential BD+Crating system confirms:
Regional Priority Credits
When an RP credit has multiple thresholds, a project earns the bonus point by meeting the base credit requirements, and an additional point may be earned for exemplary performance by exceeding the maximum threshold of the underlying credit.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
The correct answer ispoints are awarded when the maximum threshold has been exceeded(Option C), as RP credits with multiple thresholds award bonus points for exemplary performance beyond the highest threshold.
Why not the other options?
* A. Points are awarded at the minimum threshold: RP credits require achieving the base credit, not just the minimum threshold.
* B. Points are awarded at the maximum threshold: Points are awarded for exceeding the maximum threshold, not just meeting it.

TheLEED for Homes Rating System (v4)awards points for theMaterials and Resources (MR) Credit:
Environmentally Preferable Productsfor 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 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%, 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.
TheLEED v4.1 Residential BD+Crating 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 termreclaimed(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?
Reference: LEED Reference Guide for Homes Design and Construction, v4, MR Credit: Environmentally Preferable Products, p. 160.
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.Reference: LEED Reference Guide for Homes Design and Construction, v4, MR Credit: Environmentally Preferable Products, p. 160.
D). Restructured: This term is not used in LEED and does not describe the reuse of existing framing.

TheLEED for Homes Rating System (v4)outlines the requirements for theMaterials and Resources (MR) Credit: Environmentally Preferable Products, which encourages the use of sustainable materials. The credit has two options:Option 1: Local Production(materials sourced within 100 miles) andOption 2:
Environmentally Preferable Products(materials with attributes like recycled content, FSC-certified wood, or low emissions).
According to theLEED Reference Guide for Homes Design and Construction (v4):
MR Credit: Environmentally Preferable Products (1-4 points)
Earn points by meeting the following:
* Option 2: Environmentally Preferable Products: 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:
* Recycled content
* FSC-certified wood
* Bio-based materials
* Low-emission products (e.g., low-VOC paints)To earn 1 point, at least 25% of the materials (by cost) must meet two or more of these criteria.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
For 1 point, use products that meet two or more environmentally preferable criteria (e.g., recycled content, FSC-certified) for at least 25% of the total material cost.
Source: LEED v4.1 Residential BD+C, Credit Library, accessed via USGBC LEED Online.
To earnone pointunder Option 2, the project must use materials that collectively meettwo or moreof the environmentally preferable criteria (e.g., a product with both recycled content and low emissions) for at least
25% of the total material cost. This makesOption Bthe correct answer.
Why not the other options?
Reference: LEED Reference Guide for Homes Design and Construction, v4, MR Credit: Environmentally Preferable Products, p. 161.
C). Achieve more than 95% of the component by weight or volume that meets Option 1: Local Production: Option 1 focuses on local production (within 100 miles), not environmentally preferable attributes, and uses cost, not weight or volume. It is a separate compliance path.Reference: LEED Reference Guide for Homes Design and Construction, v4, MR Credit: Environmentally Preferable Products, p. 160.
D). Meet both Option 1: Local Production and Option 2: Environmentally Preferable Products: The credit allows projects to pursue either Option 1 or Option 2 independently. Meeting both is not required for one point.Reference: LEED Reference Guide for Homes Design and Construction, v4, MR Credit:
Environmentally Preferable Products, p. 160.

TheLEED for Homes Rating System (v4)includes several credits under theMaterials 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 theLEED Reference Guide for Homes Design and Construction (v4), theMR Credit:
Environmentally Preferable Productsrewards 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.
TheLEED v4.1 Residential BD+Crating 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 forEnvironmentally 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?
Reference: LEED Reference Guide for Homes Design and Construction, v4, MR Credit: Construction Waste Management, p. 164.
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.Reference: LEED Reference Guide for Homes Design and Construction, v4, MR Credit: Material-Efficient Framing, p. 158.

TheLEED for Homes Rating System (v4)includes theEnergy 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 theLEED 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.
TheLEED v4.1 Residential BD+Crating 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 earns4 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.
