The percentage of recycled content contributing to the credit is calculated based on the value of the recycled content relative to the total construction cost.
The combined value of recycled content here is $1 million (post-consumer) + $1 million (pre-consumer) = $2 million.
The percentage is then calculated as: 2,000,00010,000,000×100=20%\frac{2,000,000}{10,000,000} \times 100 = 20\%10,000,0002,000,000x100=20%
Therefore, the recycled content accounts for 20% of the total material value for the project, contributing to the Materials and Resources Credit: Building Product Disclosure and Optimization - Sourcing of Raw Materials.
NEW QUESTION # 105
A LEED AP submitted a Preliminary Design and Construction review and has received a review comment and technical advice on Materials and Resources Prerequisite, Construction and Demolition Waste Management Planning. Which of the following actions should the LEED AP do if the project continues to pursue LEED certification?
- A. Ask the General Contractor to be more aggressive with recycling goals
- B. Revise the documentation and resubmit the form
- C. Submit an appeal to Green Business Certification Inc.
- D. Abandon meeting this prerequisite
Answer: B
Explanation:
Revise the documentation and resubmit the form
If a project receives a review comment and technical advice on a prerequisite, it means that the documentation submitted was incomplete, inaccurate, or unclear, and that the project team needs to address the issues raised by the reviewer and provide additional information or clarification. The project team should revise the documentation and resubmit the form as part of the final review to demonstrate compliance with the prerequisite requirements. Abandoning meeting this prerequisite is not an option, as prerequisites are mandatory for LEED certification. Submitting an appeal to Green Business Certification Inc. is only applicable if the project team disagrees with the reviewer's decision or interpretation, and has additional evidence or arguments to support their claim. Asking the General Contractor to be more aggressive with recycling goals is not relevant to this prerequisite, as it does not address the documentation issue.
References: As per the LEED AP Building Design + Construction (LEED AP BD+C) V4 resources, the Materials and Resources Prerequisite for Construction and Demolition Waste Management Planning requires the project team to develop and implement a construction and demolition waste management plan that identifies at least five materials targeted for diversion from disposal in landfills and incinerators. The project team must also estimate a diversion rate for each material and describe how they will achieve it. The project team must submit this plan as part of the preliminary design review, along with a letter from the owner or project manager confirming that they will implement it during construction. If the reviewer finds any issues with the plan or the letter, they will provide a review comment and technical advice on how to improve it. The project team must then revise the documentation and resubmit it as part of the final design review, along with a narrative describing how they addressed the reviewer's feedback. For more detailed information, you can refer to the web-based reference guide in the credit library at USGBC's official website.

NEW QUESTION # 108
When working on a renovation project, asbestos containing materials have been found on the perimeter walls.
When calculating the percentage of building being reused under the Materials and Resources Credit, Building Life-Cycle Impact Reduction, the materials remediated will be
- A. excluded from the calculation
- B. excluded if the total volume is less than 25% of the building being reused
- C. included in the calculation
- D. excluded if the total volume is more than 25% of the building being reused
Answer: A
Explanation:
Explanation
The Materials and Resources Credit, Building Life-Cycle Impact Reduction, rewards projects that reuse existing building structures and envelopes, or salvage materials from off-site or on-site sources. According to the LEED v4 Reference Guide for Building Design and Construction, the project team must calculate the percentage of building being reused by dividing the area of the existing building structure and envelope that is reused by the total area of the completed building structure and envelope1. However, the project team must exclude from the calculation any hazardous materials that are remediated as a part of the project, such as asbestos, lead, mold, or PCBs1. Therefore, the asbestos containing materials found on the perimeter walls will be excluded from the calculation, regardless of the volume.

NEW QUESTION # 109
During preliminary energy analysis, what energy reduction strategies can best help in reducing the energy load in the new building construction project?
- A. Green roof
- B. Site conditions
- C. Programmatic and operational parameters
- D. Massing and orientation
Answer: D
Explanation:
During preliminary energy analysis, massing and orientation are energy reduction strategies that can best help in reducing the energy load in the new building construction project. Massing and orientation refer to the shape, size, and direction of the building, which affect the amount of solar heat gain, daylight, and natural ventilation that the building receives. By analyzing the massing and orientation of the building, the project team can optimize the design to minimize the heating, cooling, and lighting energy demand, and enhance the thermal comfort and indoor environmental quality of the building. The LEED v4 Reference Guide for Building Design and Construction states that "the project team should use the results of the analysis to inform the owner's project requirements, basis of design, and design documents"1. The other options, such as green roof, site conditions, and programmatic and operational parameters, are not energy reduction strategies, but factors that influence the energy performance and demand of the building.

NEW QUESTION # 110
A commercial office building with a footprint of 70,000 ft2 (6 503.2 m2) has an overall site area of 200,000 ft2 (18 580.6 m2). The project design includes 15,000 ft2 (1 393.5 m2) of pedestrian oriented hardscape and
18,000 ft2 (1 672.3 m2) of vegetated open space. Which of the following is necessary to satisfy the requirement for the outdoor space to be physically accessible when calculating the Sustainable Sites Credit, Open Space?
- A. A dark paving area with site elements to encourage parking near wetlands or naturally designed ponds
- B. A garden space with only one vegetation type and species during the summer for visual interest
- C. A garden space dedicated to industrial food production for use by local communities
- D. A pedestrian-oriented paving or turf area with physical site elements that accommodate outdoor social activities
Answer: D
Explanation:
A pedestrian-oriented paving or turf area with physical site elements that accommodate outdoor social activities is necessary to satisfy the requirement for the outdoor space to be physically accessible when calculating the Sustainable Sites Credit, Open Space. This is because the outdoor space must be designed to encourage regular use by occupants and visitors1. A garden space dedicated to industrial food production for use by local communities may not be accessible to the building occupants and visitors2. A garden space with only one vegetation type and species during the summer for visual interest does not meet the requirement of having two or more types of vegetation or overhead vegetated canopy1. A dark paving area with site elements to encourage parking near wetlands or naturally designed ponds is not considered as pedestrian-oriented hardscape and may have negative impacts on the natural environment3.

NEW QUESTION # 115
A project team has installed a rainwater harvesting system on site. In which of the following could this system be recognized?
- A. Sustainable Sites Credit, Rainwater Management and Water Efficiency Prerequisite, Indoor Water Use Reduction
- B. Sustainable Sites Credit, Rainwater Management and Water Efficiency Credit, Indoor Water Use Reduction
- C. Water Efficiency Credit, Water Metering and Water Efficiency Prerequisite, Outdoor Water Use Reduction
- D. Water Efficiency Credit, Water Metering and Water Efficiency Prerequisite, Indoor Water Use Reduction
Answer: B
Explanation:
A rainwater harvesting system on site could be recognized in the Sustainable Sites Credit, Rainwater Management and the Water Efficiency Credit, Indoor Water Use Reduction. The Sustainable Sites Credit, Rainwater Management rewards projects that reduce runoff volume and improve water quality by replicating the natural hydrology and water balance of the site1. A rainwater harvesting system can help achieve this by capturing and reusing rainwater on site2. The Water Efficiency Credit, Indoor Water Use Reduction rewards projects that reduce indoor water consumption by installing water-efficient fixtures and fittings3. A rainwater harvesting system can help achieve this by providing an alternative source of water for non-potable uses such as toilet flushing and irrigation4.
The other options are not correct. The Water Efficiency Credit, Water Metering does not recognize rainwater harvesting systems, but rather requires projects to install permanent water meters that measure the total potable water use for the building and grounds. The Water Efficiency Prerequisite, Outdoor Water Use Reduction does not recognize rainwater harvesting systems, but rather requires projects to reduce outdoor water consumption by using plant species that are native or adapted to the region and by using irrigation systems that are efficient and properly controlled. The Water Efficiency Prerequisite, Indoor Water Use Reduction does not recognize rainwater harvesting systems, but rather requires projects to reduce indoor water consumption by 20% from the baseline by installing water-efficient fixtures and fittings.

NEW QUESTION # 118
A project team is deciding on the impact of a proposed concrete walkway. Which of the following will be impacted as a result of adding the walkway?
- A. Air quality as a result of off gassing that occurs as concrete cures
- B. Erosion and sediment control plan during construction
- C. Project density calculations
- D. Site's impervious cover
Answer: D
Explanation:
Explanation
Adding a concrete walkway will increase the site's impervious cover, which is the percentage of the site area that does not allow water to infiltrate into the ground1. Impervious cover can affect the site's stormwater management, heat island effect, and habitat quality. The project team should consider using permeable paving materials, vegetated roofs, or rain gardens to reduce the impervious cover and mitigate its impacts2. The other options are not directly impacted by adding a concrete walkway. Project density calculations are based on the floor area ratio and the number of occupants, not the site features3. Erosion and sediment control plan during construction is required for any site disturbance, regardless of the type of material used4. Air quality as a result of off gassing that occurs as concrete cures is not a significant issue for outdoor applications, and can be minimized by using low-emitting concrete products5.

- A. Credit Interpretation Ruling
- B. Expedited Review
- C. Appeal Review
- D. Split Review
Answer: D
Explanation:
A split review is an optional review process that allows project teams to submit the design and construction portions of their projects separately. This can help teams determine if the project is on track to achieve LEED certification at its preferred level, and identify any issues or clarifications needed before the final review. A split review also reduces the documentation burden and review time for the construction review12.
NEW QUESTION # 123
The Sustainable Sites Credit, Heat Island Reduction takes into account both new and three-year aged Solar Reflectance Index (SRI) values for roofing material because
- A. SRI generally decreases with age
- B. SRI generally remains the same with age
- C. SRI generally does not impact the Heat Island Effect
- D. SRI generally increases with age
Answer: A
Explanation:
. SRI generally decreases with age
The Solar Reflectance Index (SRI) is a measure of the ability of a surface to reflect solar heat, as shown by a small temperature rise. It is calculated using the values of solar reflectance and thermal emittance of the surface. The higher the SRI, the lower the heat island effect. However, SRI generally decreases with age due to factors such as weathering, dirt accumulation, and biological growth. Therefore, the Sustainable Sites Credit, Heat Island Reduction takes into account both new and three-year aged SRI values for roofing material to ensure that the material maintains a high level of reflectance over time.

Identify the top-three recyclable waste streams while stating the top-two waste streams where both collection and storage space will be provided
Answer: B
Explanation:
Retail projects must conduct a waste stream audit for the duration of the project in an existing location or make projections based on historical data for similar establishments. Identify the top-five recyclable waste streams while stating the top-four waste streams where both collection and storage space will be provided. This is the requirement for Retail projects under the Materials and Resources Prerequisite, Storage and Collection of Recyclables, according to the LEED v4 BD+C Reference Guide1. The purpose of this prerequisite is to facilitate the reduction of waste generated by building occupants that is hauled to and disposed of in landfills1. The prerequisite applies to all LEED BD+C projects, but Retail projects have a different approach than other project types because of their unique waste streams and operational characteristics1. Retail projects must conduct a waste stream audit for the duration of the project in an existing location or make projections based on historical data for similar establishments. The audit or projection must identify the top-five recyclable waste streams by weight or volume using consistent metrics throughout1. The waste stream study period must be a minimum of 24 hours1. Retail projects must also provide dedicated areas that serve the entire building and are accessible to waste haulers and building occupants for the collection and storage of materials for recycling for at least four of the top-five recyclable waste streams identified by the audit or projection1.

Conducting this analysis at an early stage helps inform sustainable water use strategies and enables more effective decision-making on fixtures, water conservation technologies, and landscape design. This proactive approach aligns with LEED's emphasis on resource conservation in design.
NEW QUESTION # 127
The total land area within a 1/4 mi. (0.40 km) radius of a project boundary consists of 130 acres (53 hectares) and has a residential to nonresidential ratio of 60:40. Within this same total land area, there are 780 dwelling units and 1,600,000 ft2 (148 645 m2) of nonresidential building space. Given these parameters, what are the surrounding residential and nonresidential densities when attempting to achieve Location and Transportation Credit, Surrounding Density and Diverse Uses?
- A. 13 dwelling units per acre (32 dwelling units per hectare) and a FAR of 0.47
- B. 15 dwelling units per acre (36 dwelling units per hectare) and a FAR of 0.70
- C. 10 dwelling units per acre (24 dwelling units per hectare) and a Floor Area Ratio (FAR) of 0.47
- D. 10 dwelling units per acre (24 dwelling units per hectare) and a FAR of 0.70
Answer: A
Explanation:
The surrounding residential density is calculated by dividing the total number of dwelling units by the total residential land area. In this case, it would be 780 dwelling units divided by 60% of 130 acres, which equals approximately 13 dwelling units per acre (or 32 dwelling units per hectare).
The nonresidential density, or Floor Area Ratio (FAR), is calculated by dividing the total nonresidential building floor area by the total nonresidential land area. In this case, it would be 1,600,000 ft² divided by 40% of 130 acres, which equals a FAR of approximately 0.47.
These calculations are used when attempting to achieve the Location and Transportation Credit, Surrounding Density and Diverse Uses, under the LEED AP BD+C V4 rating system.
