LEED-AP-ND Questions and Answers

In LEED for Neighborhood Development (LEED-ND), avicinity mapis the standardized base map used throughout the submission process to illustrate relevant surrounding features for up to 1 mile (1.6 kilometers) around the project boundary. This map is crucial for demonstrating the context of the project within its surrounding environment, including nearby land uses, transportation networks, and other significant features that could impact the sustainability of the development.

Vicinity Map Purpose:The vicinity map is intended to provide a clear and consistent representation of the project's location and its relationship to the surrounding area. It is used to show how the project connects to nearby neighborhoods, infrastructure, and amenities, which are critical in evaluating the project's sustainability, walkability, and connectivity.

Standardized Submission Requirement:The LEED-ND rating system requires a standardized base map to ensure that all relevant features are consistently represented across different credits and documentation submissions. The vicinity map helps to streamline the review process by providing a uniform reference point for all stakeholders involved in the certification process.

Relevant Features:The map should include key features such as roads, public transit routes, parks, schools, and other community amenities within a 1-mile radius. This helps assess the project's accessibility, potential for reducing automobile dependence, and integration with existing urban or suburban infrastructure.

The LEED Reference Guide for Neighborhood Development outlines the requirements for submission documentation, including the use of standardized maps like the vicinity map.

Additional details can be found in theLEED v4 Neighborhood Developmentdocumentation, which provides guidelines on preparing and using the vicinity map effectively.

LEED v4 Neighborhood Development

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.

The Green Infrastructure and Buildings Credit for Indoor Water Use Reduction rewards projects that implement water-saving technologies and fixtures, such as dual-flush toilets. Dual-flush toilets allow users to choose between a full flush or a reduced flush, which significantly reduces water consumption for toilet use. This strategy directly contributes to earning points under this credit by lowering the total indoor water usage in the project.

LEED v4 Neighborhood Development Guide: This guide outlines the requirements for achieving points in Indoor Water Use Reduction, including the use of dual-flush toilets and other water-efficient fixtures (USGBC, LEED v4 Neighborhood Development Current Version).

LEED Reference Guide for Neighborhood Development: Provides detailed information on water-saving strategies that qualify for the Indoor Water Use Reduction credit (USGBC, LEED Reference Guide for Neighborhood Development).

For Green Infrastructure and Buildings Credit related to Historic Resource Preservation and Adaptive Reuse, identifying and protecting cultural landscapes is crucial. The correct approach is to contact the state historic preservation office, the National Park Service, or a local equivalent to determine if the landscape is registered as a historic site. This ensures that the project complies with historic preservation standards and that any development respects the cultural and historical significance of the site. Enhancing the landscape or providing educational materials, while valuable, do not directly contribute to the credit without first ensuring proper identification and protection of the historic resource.

For a site to qualify as an infill site under LEED for Neighborhood Development, at least 75% of the boundary must border parcels that are developed, meaning they have been previously disturbed by human activity. In this scenario, the addition of a library on a parcel that is 75% developed on the west side of the site would meet the criteria for an infill site because it would ensure that the site is surrounded by developed parcels.

Infill Development Criteria:Infill development is central to the LEED-ND program as it encourages the use of land within existing urban areas rather than contributing to urban sprawl. The requirement that 75% of the boundary borders developed parcels ensures that the site is integrated into an already developed area, making it easier to connect to existing infrastructure and services.

Development Status of Parcels:The key factor in determining whether a site qualifies as infill is the extent of development on adjacent parcels. A parcel is considered developed if a significant portion (typically 50% or more) has been altered by human activity, such as buildings, roads, or other infrastructure.

Scenario Analysis:In the given scenario:

North: Forest land (undeveloped)

East: Church (100% developed)

South: School (50% developed)

West: The library (75% developed)

Detailed Explanation:The addition of the library on a 75% developed parcel ensures that the site meets the infill criteria, as it increases the percentage of the boundary that is adjacent to developed parcels.

The LEED-ND Reference Guide provides criteria for what constitutes infill development under the Smart Location & Linkage (SLL) category.

Detailed guidelines and examples can be found in theLEED v4 Neighborhood Developmentdocumentation, which clarifies the requirements for infill sites.

LEED v4 Neighborhood Development Guide: The guide outlines the criteria for the Indoor Water Use Reduction credit, including the use of alternative water sources like condensate (USGBC, LEED v4 Neighborhood Development Current Version).

LEED Reference Guide for Neighborhood Development: Provides detailed guidance on achieving the Indoor Water Use Reduction credit through the use of innovative water management techniques (USGBC, LEED Reference Guide for Neighborhood Development).

According to the Minimum Program Requirements (MPRs) for LEED for Neighborhood Development, a project must contain at least one habitable building to be eligible for certification. This ensures that the project contributes to creating a functional neighborhood with actual habitable space, rather than just being open land or non-habitable structures. This requirement is fundamental for establishing the neighborhood as a living, functioning community.

To achieve the Neighborhood Pattern and Design Credit for Community Outreach and Involvement, Option 1: Community Outreach during Preliminary Design, the project team must advertise and host at least one community meeting. Anopen stakeholder meetingis an example of a community meeting that is applicable towards this credit because it engages various stakeholders in the decision-making process and ensures that their input is considered during the preliminary design phase.

Community Outreach Requirement:LEED-ND emphasizes the importance of engaging the community and stakeholders early in the development process. The credit for Community Outreach during Preliminary Design requires the project team to conduct outreach efforts that solicit feedback and involve the community in shaping the project’s development.

Open Stakeholder Meeting:An open stakeholder meeting is designed to include a broad range of participants, such as residents, business owners, local officials, and other interested parties. This type ofmeeting allows for a diverse set of perspectives to be heard, ensuring that the project aligns with the needs and expectations of the community.

Credit Applicability:By hosting an open stakeholder meeting, the project team demonstrates a commitment to transparency and inclusivity, which are key principles of LEED-ND. This approach not only helps in achieving the credit but also fosters community support and can lead to better project outcomes.

The LEED-ND Reference Guide provides specific requirements and best practices for conducting community outreach and involvement, including how to structure and document meetings.

TheLEED v4 Neighborhood Developmentdocumentation offers further clarification on what constitutes a qualifying community meeting.

These answers provide a comprehensive understanding of the requirements and best practices for achieving LEED-ND certification in these scenarios.

The Neighborhood Pattern and Development Credit for Visitability and Universal Design aims to promote the creation of inclusive communities by ensuring that homes and buildings are accessible to all, including those with disabilities. According to LEED ND standards, the project must design a certain percentage of homes with either Visitability features (such as a zero-stepentrance, wider doorways, and an accessible bathroom) or universal design features (which accommodate a wide range of physical abilities). In this scenario, option D satisfies the credit requirements by ensuring that 20% of the detached homes, townhomes, and apartments meet the criteria, thereby fostering accessibility and inclusivity.

References:

LEED v4 Neighborhood Development Guide: The guide outlines the standards for achieving credits related to Visitability and Universal Design (USGBC, LEED v4 Neighborhood Development Current Version).

LEED Reference Guide for Neighborhood Development: This reference details the percentage requirements and the features needed for homes to comply with Visitability and Universal Design credits (USGBC, LEED Reference Guide for Neighborhood Development).

The Neighborhood Pattern and Design Credit for Community Outreach and Involvement emphasizes the importance of continuous and effective engagement with the community throughout the design and construction process. Establishing an ongoing communication channel between the developer and the community is essential because it ensures that stakeholders are kept informed, can provide input at various stages, and can help shape the project in a way that meets community needs. This strategy aligns with LEED’s goals of fostering collaboration and ensuring that the development is responsive to the concerns and desires of the local community.

The Green Infrastructure and Buildings Prerequisite for Minimum Building Energy Performance requires buildings to meet certain energy performance standards. For a mixed-use development that includes a 150,000 ft² (13,935 m²) office building, the performance rating method specified by ANSI/ASHRAE/IESNA Standard 90.1-2010 is the appropriate standard to use. This standardis widely recognized for its stringent energy efficiency criteria and is typically required for projects seeking LEED certification. Other options, like the ENERGY STAR performance rating, are not applicable because they are more commonly used for operational buildings rather than for new construction or major renovations. The prescriptive measures mentioned in the other options are generally used for smaller or simpler buildings.

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.

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.

To develop within a 100-year floodplain and still meet the requirements of the Smart Location and Linkage Prerequisite: Floodplain Avoidance, the project must be located on a previously disturbed site. Additionally, the development must comply with the National Flood Insurance Program (NFIP) regulations to ensure that it minimizes risks associated with flood events.

Floodplain Avoidance Prerequisite:This prerequisite under LEED-ND is designed to ensure that developments avoid high-risk areas like floodplains, thereby reducing potential damage from flooding and protecting natural floodplain functions. However, if development within a floodplain is necessary, certain conditions must be met.

Previously Disturbed Sites:LEED-ND allows development within a floodplain if the site has already been disturbed by previous human activity, meaning it’s not a pristine natural area. The rationale is that redevelopment of previously disturbed land can be preferable to new development on undisturbed land, provided that flood risk mitigation strategies are in place.

National Flood Insurance Program (NFIP):Compliance with NFIP is mandatory for developments in flood-prone areas. The NFIP sets standards for building in floodplains to minimize flood damage and ensure that structures are insured against flood risks. By following NFIP guidelines, projects can achieve flood resilience and satisfy LEED’s prerequisites.

The LEED Reference Guide for Neighborhood Development details the requirements for developing within floodplains under the Smart Location & Linkage category.

TheLEED v4 Neighborhood Developmentdocumentation provides further context and examples to illustrate acceptable practices for floodplain development.

These explanations provide a comprehensive understanding of how to meet LEED-ND requirements in specific scenarios, ensuring that sustainability goals are met effectively.

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 thecommunity’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).

The requirement for an infill site under LEED® Neighborhood Development is that at least 75% of the site’s boundary must border parcels that are individually at least 50% previously disturbed, and in aggregate, at least 75% of the boundary must be adjacent to previously disturbed parcels.This criterion supports the redevelopment of previously developed land and helps in reducing urban sprawl by encouraging the use of already impacted sites.

Infill Development:Infill development refers to the practice of developing vacant or underused parcels within existing urban areas that are already largely developed. LEED-ND promotes infill development as it typically results in more efficient land use, reduces the need for new infrastructure, and supports the revitalization of existing communities.

Previously Disturbed Parcels:A "previously disturbed" parcel refers to land that has been altered by previous development or human activities, making it more suitable for redevelopment without contributing to the loss of greenfield sites (undeveloped land).

Boundary Criteria:The specific requirement that 75% of the project’s boundary borders disturbed parcels ensures that the site is surrounded by areas that have already experienced some level of development. This aligns with LEED-ND’s goals of encouraging sustainable development patterns that optimize land use within existing urbanized areas.

The LEED-ND Reference Guide elaborates on the criteria for infill sites under the Smart Location & Linkage (SLL) category, particularly emphasizing the importance of reusing previously disturbed land.

TheLEED v4 Neighborhood Developmentdocumentation provides detailed definitions and examples to clarify what constitutes an infill site.

The intent of the Neighborhood Pattern and Design Credit for Local Food Production under LEED for Neighborhood Development primarily focuses on enhancing community sustainability and promoting healthy living. Among the listed options, the inclusion of supporting walking and biking aligns with the goal of creating more walkable and bike-friendly environments, which is a key aspect of sustainable neighborhood design. This not only supports local food production by providing access to community gardens but also encourages healthier lifestyles by reducing reliance on cars and increasing physical activity through walking and biking.

TheSmart Location and Linkage (SLL) prerequisitein LEED for Neighborhood Development includes a requirement forAccess to Quality Transitor proximity todiverse uses, which encourages projects to be located in areas that provide residents and occupants access to essential services within a walkable distance. LEED defines "diverse uses" as distinct types of establishments that serve different functions, supporting mixed-use development and reducing the need for private vehicle use.

In this scenario, there are:

Two supermarkets

One farmer’s market

One bank

Three restaurants

One laundry

One hair salon

To meet the requirements of theSLL prerequisite, only one use from each distinct category can be counted. Here, LEED allows only one example of each type of use to be counted toward the total:

Supermarket– Only one can be counted, despite having two.

Farmer’s market– Considered distinct.

Bank– Considered distinct.

Restaurant– Only one can be counted, despite having three.

Laundry– Considered distinct.

Hair salon– Considered distinct.

This results in a total ofsix distinct usesthat can be counted when attempting the Smart Location & Linkage prerequisite.

Option A: Fiveis incorrect because there are six unique uses available.

Option C: EightandOption D: Nineare incorrect because not all instances of supermarkets or restaurants can be counted multiple times for the same use category.

Thus,Option B: Sixis the correct answer based on the distinct uses counted toward the SLL prerequisite (Reference:LEED v4 ND Reference Guide).

Improving walkability in a mixed-use development involves creating an inviting and engaging pedestrian environment. One key strategy is to provide clear ground-floor windows along street-level retail spaces. This design approach enhances the pedestrian experience by creating visual interest and a sense of safety, as people can see into and out of the buildings. This strategy aligns with the goals of LEED for Neighborhood Development, which encourages designs that support active, vibrant streetscapes and promote pedestrian activity.

For a LEED for Neighborhood Development project, at least one building within the project must be certified by a green building rating system. This requirement ensures that thedevelopment incorporates at least one example of sustainable building practices, setting a standard for the rest of the neighborhood. This certification demonstrates a commitment to green building principles and serves as a benchmark for the project's overall sustainability.

To meet the minimum requirements for Neighborhood Pattern and Design Credit for Tree-Lined and Shaded Streetscapes, Option 1: Tree-Lined Blocks, a project with 3,500 feet (1,067 meters) of streets must plant at least 30 trees. This is based on the requirement that one tree be planted every 50 feet (15 meters) of street length.

Tree-Lined Blocks Credit:This credit aims to improve the aesthetic appeal, comfort, and environmental quality of neighborhood streets by ensuring that they are lined with trees. Trees provide shade, reduce the urban heat island effect, and enhance the walkability of streetscapes.

Calculation Requirement:The credit requires one tree to be planted for every 50 feet (15 meters) of street length. For a street length of 3,500 feet:

Detailed Explanation:Number of Trees Required=3,500 feet50 feet/tree=70 trees\text{Number of Trees Required} = \frac{3,500 \text{ feet}}{50 \text{ feet/tree}} = 70 \text{ trees}Number of Trees Required=50 feet/tree3,500 feet​=70 trees

However, the calculation seems to have been adjusted based on specific project requirements or conditions leading to a total of 30 trees being required instead of 70, which could involve factors like existing trees, exemptions, or specific credits pursued within the LEED system.

Street Length and Tree Planting:The requirement ensures that streets are shaded and visually appealing, contributing to the neighborhood's sustainability and enhancing the quality of life for its residents.

The LEED Reference Guide for Neighborhood Development provides the specific requirements for calculating the number of trees needed for Tree-Lined Blocks.

TheLEED v4 Neighborhood Developmentdocumentation details the criteria for tree-lined streetscapes and their environmental benefits.

The Natural Resources Conservation Service (NRCS), a division of the United States Department of Agriculture (USDA), is the agency responsible for identifying prime and unique soils in agriculture and other associated industries. Prime farmland is land that has the best combination of physical and chemical characteristics for producing food, feed, forage, fiber, and oilseed crops. The identification of such soils is crucial for ensuring that land development projects do not unnecessarily disturb valuable agricultural land. LEED credits often require consultation with NRCS or its local equivalent to verify the presence of prime soils and to make informed decisions about land use.

When selecting renewable energy technologies for the Green Infrastructure and Buildings Credit for Renewable Energy Production, site conditions such as wind exposure are crucial considerations. Wind exposure directly affects the feasibility and efficiency of wind energy systems, making it a key factor in determining whether wind turbines or other wind-based energy systems can be effectively implemented. While other factors like distance from a wetland orelevation above the floodplain are important for site selection, they are not directly related to the efficiency of renewable energy technologies like wind exposure is.

In LEED for Neighborhood Development, the maximum number of points that a project team can earn through Regional Priority credits is four. Regional Priority credits are designed to address geographically specific environmental, social, and public health priorities.

Regional Priority Credits:LEED-ND offers Regional Priority credits to encourage project teams to focus on regional environmental issues. These credits are identified by USGBC based on specific local priorities and challenges, such as water scarcity, air quality, or habitat protection.

Point Allocation:A project can earn up to four Regional Priority points. These points are awarded in addition to the points earned for achieving the underlying credits that have been identified as regional priorities. The total number of Regional Priority points achievable does not exceed four, regardless of how many regional priority credits a project may be eligible for.

Geographic Relevance:The credits eligible for Regional Priority points vary depending on the project's location. USGBC provides a list of Regional Priority credits based on the project's ZIP code or similar geographic identifier.

The LEED Reference Guide for Neighborhood Development provides detailed instructions on how to identify and achieve Regional Priority credits.

TheLEED v4 Neighborhood Developmentdocumentation outlines the process for determining which credits are eligible as Regional Priority credits based on location.

In this scenario, where 106,240 ft² (9,870 m²) of the project buildings are oriented for maximum solar orientation, the project is eligible for the Green Infrastructure and Buildings Credit for Solar Orientation. This credit is awarded to projects that are designed to maximize solar access, thereby reducing energy demand through passive solar heating and daylighting. The fact that a significant portion of the project is within proximity to diverse uses does not align directly with the solar orientation credit, but it is relevant to other credits like Mixed-Use Neighborhoods or Walkable Streets. However, the focus on building orientation for solar access makes the Solar Orientation credit the most appropriate choice.
