US Green Building Council LEED AP ND LEED AP Neighborhood Development Exam Practice Test

Answer : B

For the Green Infrastructure and Buildings Credit: Infrastructure Energy Efficiency, the baseline energy use is an important metric. The goal of this credit is to encourage the use of energy-efficient infrastructure components such as lighting, pumps, and water distribution systems. To determine energy efficiency improvements, the baseline must be established based on standard practice for infrastructure elements.

Option B: the lowest first-cost infrastructure item assumed for the project is the correct answer. In this context, the baseline energy use refers to the energy consumption of the least expensive, standard infrastructure items that would normally be used in the project if no energy efficiency measures were implemented. This establishes the base case against which the energy performance improvements of more efficient systems can be measured. LEED then rewards projects that exceed this baseline with more energy-efficient infrastructure solutions (Reference: LEED v4 ND Reference Guide).

Option A: current infrastructure items used by IgCC standard is incorrect because the International Green Construction Code (IgCC) may be a helpful reference for sustainable construction, but it is not used as the baseline for this LEED credit.

Option C: infrastructure items recommended by the National Lighting Safety Institute is also incorrect. While this organization may provide guidelines on lighting safety, it is not relevant to the energy baseline determination.

Option D: a 15% increase above the minimum requirements for infrastructure items in the state's energy code is not applicable, as the baseline is determined by the lowest-cost infrastructure, not by a predetermined increase above state energy code requirements.

Thus, the baseline for energy use in this credit is determined by the lowest-cost, conventional infrastructure items, making Option B the correct answer (Reference: LEED Reference Guide for Neighborhood Development).

Answer : A

For a project located in a Federal Empowerment Zone to qualify for the Smart Location and Linkage Credit under Preferred Locations Option 3: Designated High-Priority Locations, the project must also meet certain affordability criteria. Specifically, providing at least 10% of total rental units priced at or below 60% of the area median income (AMI) aligns with the requirements for achieving this credit. This ensures that the development supports affordable housing in addition to being located in a high-priority area.

LEED v4 Neighborhood Development Guide: Details the requirements for Designated High-Priority Locations, including the criteria related to affordable housing (USGBC, LEED v4 Neighborhood Development Current Version).

LEED Reference Guide for Neighborhood Development: Offers guidance on how to achieve the Preferred Locations credit by meeting affordability thresholds (USGBC, LEED Reference Guide for Neighborhood Development).

Answer : C

Installing highly efficient street lights and traffic lights throughout a neighborhood project contributes directly to the Infrastructure Energy Efficiency credit. This credit encourages the use of energy-efficient infrastructure to reduce the overall energy consumption of the project. By using efficient lighting, the project can lower its operational energy use, reduce greenhouse gas emissions, and contribute to the sustainability goals of the neighborhood.

Answer : A

For a project to qualify for LEED Neighborhood Development certification, it must meet specific Minimum Program Requirements (MPRs). One of these MPRs is that the project must contain at least one habitable building and must not exceed 1,000 acres (405 hectares) in size. This requirement ensures that the project is of a scale appropriate for a neighborhood development, allowing for effective management and adherence to sustainability principles.

Detailed Explanation:

Minimum Program Requirements (MPRs): MPRs are fundamental criteria that any project must satisfy to be eligible for LEED certification. These requirements are designed to ensure that projects meet basic sustainability and operational benchmarks necessary for certification.

Habitable Building: The inclusion of at least one habitable building is essential because LEED-ND focuses on creating sustainable communities where people live, work, and interact. The presence of a habitable building ensures that the project serves a functional purpose within the community.

Project Size: Limiting the project size to no more than 1,000 acres (405 hectares) ensures that the development is manageable and can integrate sustainable practices effectively across the entire area. This limitation also prevents overly large developments that might strain local resources or infrastructure.

The LEED Reference Guide for Neighborhood Development details the Minimum Program Requirements necessary for certification, including the requirements for habitable buildings and project size.

Answer : C

The Smart Location and Linkage Prerequisite: Wetland and Water Body Conservation in LEED for Neighborhood Development aims to protect natural hydrological systems by ensuring that development does not negatively impact wetlands and water bodies. Projects must avoid development on land that would disrupt these sensitive ecological areas or mitigate their impact if such development is unavoidable.

Option C: A brownfield redevelopment is the correct answer because brownfield sites are typically previously developed lands that may have been contaminated or disturbed. When a project is located on a brownfield site, it avoids impacting previously undisturbed wetlands or water bodies, as brownfields have already undergone substantial disturbance. LEED incentivizes the reuse and redevelopment of such sites as it aligns with sustainable land-use practices and avoids the need to develop on pristine or sensitive environmental areas, including wetlands and water bodies. Therefore, projects on brownfield sites automatically comply with the Wetland and Water Body Conservation prerequisite (Reference: LEED v4 ND Reference Guide).

Option A: An infill site may or may not comply automatically with this prerequisite depending on whether the site includes or affects wetlands or water bodies. Infill sites can be adjacent to or even contain sensitive areas.

Option B: An adjacent site does not necessarily ensure compliance with this prerequisite. Adjacent development could still affect nearby wetlands or water bodies if it is not planned carefully.

Option D: On previously disturbed land does not guarantee compliance, as previously disturbed land may still contain wetlands or be near water bodies that require protection.

In summary, brownfield redevelopment projects inherently avoid negatively impacting wetlands and water bodies, making Option C the correct choice for automatic compliance with the Wetland and Water Body Conservation prerequisite.

Answer : D

The intent of the Neighborhood Pattern and Design Credit for Community Outreach and Involvement is to foster engagement and responsiveness to the needs and concerns of community members who live or work in the area being developed. This credit encourages developers to actively involve the community in the planning process, ensuring that the project aligns with the community's values and addresses local issues. It promotes transparency and collaboration, leading to developments that better serve the community's needs.

LEED v4 Neighborhood Development Guide: The guide emphasizes the importance of community outreach and involvement in the development process (USGBC, LEED v4 Neighborhood Development Current Version).

LEED Reference Guide for Neighborhood Development: Provides detailed strategies for achieving this credit by engaging with local community members and stakeholders (USGBC, LEED Reference Guide for Neighborhood Development).

Answer : D

For the Neighborhood Pattern and Design Credit for Tree-Lined and Shaded Streetscapes, Option 2: Shaded Sidewalks, the crown diameter of newly planted trees used in calculating the percentage of shaded sidewalks is based on their expected size 10 years after planting.

Detailed Explanation:

Shaded Sidewalks Credit: This credit aims to increase the comfort and usability of sidewalks by ensuring they are shaded, reducing heat exposure and improving the pedestrian experience. The shade coverage must be calculated based on the anticipated tree canopy.

Crown Diameter Calculation: LEED requires that the shading potential of newly planted trees be projected based on the tree's expected crown diameter 10 years after planting. This approach ensures that the shading provided is realistic and sustainable over time.

Long-Term Planning: Using the 10-year crown diameter allows project teams to plan for the future growth of trees and ensure that sidewalks will be adequately shaded as the neighborhood matures. This long-term perspective is crucial for maintaining sustainable urban environments.

The LEED Reference Guide for Neighborhood Development specifies how to calculate tree canopy coverage and how future growth is factored into these calculations.

The LEED v4 Neighborhood Development documentation provides additional guidelines on selecting tree species and projecting their growth.
