LEED-AP-ND LEED AP Neighborhood Development (LEED ND) Questions and Answers

Donating salvaged lumber to a local community organization for use in building low-income housing contributes toward the Green Infrastructure and Buildings (GIB) Credit for Recycled and Reused Infrastructure. This credit encourages the reuse of materials to reduce waste and the demand for new materials, thereby lowering the environmental impact associated with material production and disposal. By donating salvaged lumber, the project supports the goals of recycling and reuse, which aligns with the credit's intent.

TheNeighborhood Pattern and Design (NPD) Credit: Transportation Demand Management (TDM)encourages the implementation of strategies to reduce the reliance on single-occupancy vehicles and promote alternative, more sustainable modes of transportation. This credit aims to decrease vehicle miles traveled (VMT), reduce traffic congestion, and lower greenhouse gas emissions by encouraging the use of public transportation, car-sharing, cycling, and walking.

Option C: Subsidize yearly transportation passes by at least 50% for 100% of the occupants of the project for a minimum of three yearsis the correct answer because subsidizing public transportation passes for all occupants encourages the use of transit, which directly reduces vehicle usage. LEED specifically recognizes this strategy as a way to reduce transportation demand by making public transit more accessible and affordable for residents and workers, aligning with the goals of the TDM credit (Reference:LEED v4 ND Reference Guide).

Option A: Obtain a variance to allow a 25% reduction from local regulatory minimum parking requirementsis not sufficient on its own to meet the TDM credit requirements, although reducing parking can contribute to overall demand management efforts.

Option B: Sell or rent associated parking spaces separately from 50% of dwelling units and/or nonresidential square footageis a parking management strategy that can reduce the demand for parking, but it does not fully satisfy the intent of the TDM credit by itself.

Option D: Ensure that 50% of the residential units and non-residential buildings are within a 1/4 mi (0.4 km) walking distance of a shared vehicleis an effective TDM strategy, but the subsidized transportation passes (Option C) are a more direct and impactful strategy to reduce transportation demand.

Thus,subsidizing yearly transportation passesis the most direct and impactful strategy for meeting the Transportation Demand Management credit in LEED ND, makingOption Cthe correct answer.

When defining the boundary of a project site on an urban waterfront, a dock to be constructed by the developer can be included. This is because it is a planned and integral part of the project’s development. Other options like houseboats, marinas, or jetties that were in place prior to the issuance of the certificate of occupancy or the date of property acquisition are generally not included in the project boundary as they were not part of the project’s initial development plans. LEED requires that all project-related infrastructure, especially those constructed as part of the project, be included within the project boundary.

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.

For the Green Infrastructure and Buildings Credit on Transit Facilities, only bus stops that are operational by the time of project completion can be included in the credit documentation. In this scenario, since only one of the proposed bus stops will be in operation at the time of project completion, only this stop can be included in the application form. Stops that will become operational after project completion cannot be counted toward the credit.

References:

LEED v4 Neighborhood Development Guide: This guide discusses the credit criteria for Transit Facilities, specifying that only currently operational or immediately operational stops can be included (USGBC, LEED v4 Neighborhood Development Current Version).

LEED Reference Guide for Neighborhood Development: Offers specific instructions on documenting transit facilities, including the requirement that stops must be operational at project completion (USGBC, LEED Reference Guide for Neighborhood Development).

Within the required buffer zone around a wetland or body of water, minor improvements such as the addition of bicycle and pedestrian pathways are permitted under specific conditions. The pathways must not exceed 12 feet (3.5 meters) in width, and no more than 8 feet (2.5 meters) of their width can be impervious (non-permeable).

Buffer Zone Requirements:LEED-ND has strict guidelines for protecting wetlands and water bodies to maintain their ecological integrity. However, the rating system allows for certain minor improvements within these buffer zones to enhance public access and appreciation of these natural features.

Pathway Specifications:The specified limits on the width and imperviousness of the pathways ensure that the improvements do not significantly disrupt the natural hydrology or increase runoff into the wetland or water body. By limiting the impervious surface area, the pathways allow for better water infiltration and reduce the potential for erosion or other negative impacts on the ecosystem.

Public Access:Providing public access through such pathways aligns with LEED’s goals of promotingsustainable and healthy communities by encouraging outdoor recreation and non-motorized transportation while preserving the natural environment.

The LEED Reference Guide for Neighborhood Development provides detailed criteria for permissible activities within buffer zones.

TheLEED v4 Neighborhood Developmentdocumentation further elaborates on the conditions under which minor improvements, like pathways, can be implemented.

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.

For the Green Infrastructure and Buildings Credit related to Renewable Energy Production, cogeneration of electricity and heat using mill residue biomass is an eligible source of renewable energy. This process, also known as combined heat and power (CHP), efficiently uses biomass to generate both electricity and thermal energy, reducing overall energy consumption and greenhouse gas emissions. Passive solar heating strategies, while beneficial for reducing energy demand, do not directly produce renewable energy. Geothermal energy used with a ground-source heat pump is generally considered energy efficiency rather than renewable energy. Photovoltaic energy generation from off-site locations may not qualify unless it is directly tied to the project.

The development of a central plant that burns biomass products to provide space heating and hot water is directly aligned with the Green Infrastructure and Buildings Credit for District Heating and Cooling. This credit rewards projects that implement district energy systems that use renewable energy sources, such as biomass, to provide heating and cooling to multiple buildings in a development. By using biomass, the project reduces reliance on fossil fuels, lowersgreenhouse gas emissions, and increases energy efficiency, all of which are key objectives of this credit.

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).

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.

The Smart Location and Linkage (SLL) Prerequisite for Smart Location in LEED for Neighborhood Development can be met in several ways, including locating the project in a receiving area for a Transfer of Development Rights (TDR) program. A TDR program allows development rights to be transferred from areas designated for conservation (sending areas) to areas more suitable for development (receiving areas). If a project is located in a receiving area, it supports regional goals of conserving land and directing development to appropriate locations, which aligns with the LEED ND Smart Location prerequisite.

For the scenario provided, where 30% of the infrastructure components contain post-consumer recycled content and 10% by mass are on-site reuse materials, an additional 10% of the infrastructure's mass must come from pre-consumer materials to meet the LEED requirements for recycled content.

Recycled Content Credit:The use of recycled materials in infrastructure contributes to sustainability by reducing the demand for virgin materials and minimizing waste. LEED credits are awarded based on the percentage by mass of recycled content in infrastructure materials.

Recycled Content Categories:

Post-consumer recycled contentrefers to materials recycled after they have been used by consumers, such as paper, metals, or plastics.

Pre-consumer recycled contentinvolves materials that are recycled from manufacturing waste, before they reach the consumer, such as scraps or trimmings.

Required Additional Percentage:In this scenario, the project already has 30% post-consumer and 10% on-site reuse. To maximize the recycled content credit, an additional 10% by mass of the materials must come from pre-consumer recycled content, bringing the total recycled content to 50% (30% post-consumer, 10% pre-consumer, 10% on-site reuse).

The LEED Reference Guide for Neighborhood Development details the calculations and criteria for earning recycled content credits.

Connecting to the municipal graywater system contributes toward the Green Infrastructure and Buildings Credit for Wastewater Management. This credit focuses on reducing the impact of wastewater generated by the project by encouraging the use of graywater systems for recycling and reusing water, thus minimizing the demand on municipal wastewater treatment facilities.

Graywater Systems:Graywater refers to wastewater from domestic sources like sinks, showers, and laundry that can be recycled for non-potable uses such as irrigation or toilet flushing. By connecting to a municipal graywater system, the project can contribute to reducing the overall volume of wastewater that needs to be treated, thereby earning points under the Wastewater Management credit.

Wastewater Management Credit:The intent of this credit is to minimize the adverse effects of wastewater on theenvironment. Projects can earn points by implementing strategies that reduce the volume of wastewater, treat it on-site, or connect to systems that facilitate its reuse.

Benefits of Municipal Graywater Systems:Using a municipal graywater system helps in reducing the strain on local wastewater treatment facilities and promotes the sustainable use of water resources. It also aligns with LEED’s broader goals of water conservation and efficient water use.

The LEED Reference Guide for Neighborhood Development outlines the criteria for the Wastewater Management credit and how connecting to graywater systems can contribute to achieving it.

TheLEED v4 Neighborhood Developmentdocumentation provides additional guidance on the types of wastewater systems that are eligible for this credit.

To earn one point under theInnovation Credit: LEED Accredited Professional (AP)in a LEED for Neighborhood Development (ND) project, the individual must hold theLEED AP Neighborhood Development (LEED AP ND)credential. This credential signifies that the individual has specialized knowledge in the principles and processes specific to neighborhood development and sustainability, aligning directly with the requirements and intent of LEED ND.

Option A: LEED AP Neighborhood Developmentis the correct answer because to earn this specific credit in a LEED ND project, the LEED AP must hold theNeighborhood Development (ND)specialty. This ensures that the individual’s expertise is aligned with the specific challenges and opportunities in neighborhood development, rather than other building-focused specialties (Reference:LEED v4 ND Reference Guide).

Option B: LEED AP Building Design and Constructionwould not qualify for this credit in a LEED ND project, as it focuses on the building level rather than neighborhood-scale development.

Option C: Any LEED AP without specialty credentialis not sufficient for the Innovation Credit. LEED requires a specialty credential related to the specific project type (in this case, Neighborhood Development).

Option D: LEED AP with any specialty credentialis also incorrect because LEED ND specifically requires theNeighborhood Developmentspecialty for this credit, not just any specialty.

Thus, the correct answer isA. LEED AP Neighborhood Development.

To be eligible for the Neighborhood Pattern and Design (NPD) Credit for Reduced Parking Footprint, a project must minimize the amount of land dedicated to parking. Specifically, this credit discourages parking lots located in front of buildings, as they detract from the walkability and pedestrian-friendly environment that LEED ND encourages. By removing the surface parking lot in front of the building, the project can improve its walkability, reduce the parking footprint, and better align with the credit requirements.

A snow storage system that uses collected snow in the winter to cool water for a neighborhood central plant during the summer would contribute to the Green Infrastructure and Buildings credit for Optimizing Building Energy Performance. This innovative system reduces the energy needed for cooling by utilizing natural, renewable resources, thereby enhancing the overall energy efficiency of the development.

Optimize Building Energy Performance Credit:This credit aims to reduce the energy demand of buildings through design strategies and technologies that improve energy efficiency. By optimizing energy use, projects can significantly lower their environmental impact and operational costs.

Snow Storage System:The snow storage system in question utilizes a natural process where snow, collected in winter, is stored and then used to cool water for a central plant in summer. This method reduces reliance on traditional, energy-intensive cooling systems such as air conditioning, thereby saving energy.

Renewable and Efficient Energy Use:This system aligns with the objectives of the Optimize Building Energy Performance credit by reducing the need for mechanical cooling. It is an example of how leveraging local climatic conditions and natural processes can contribute to sustainable building operations.

The LEED Reference Guide for Neighborhood Development provides guidelines on how innovative energy-saving strategies, like snow storage systems, can be applied to earn points under the Optimize Building Energy Performance credit.

These explanations provide a thorough understanding of how specific project features can contribute to earning LEED-ND credits and meeting sustainability goals.

If a project site is an infill site, it contributes to Agricultural Land Conservation by avoiding the use of undeveloped, agricultural land for new development. Infill sites, typically located within already developed urban areas, help to preserve agricultural land by focusing development on underutilized or vacant parcels within existing communities.

Infill Development and Agricultural Land:Infill development is a key strategy in LEED-ND for conserving agricultural land, which is often at risk from urban sprawl. By concentrating development within existing urbanized areas, the need to convert farmland or other undeveloped land into new development is reduced, preserving these areas for agricultural use and ecological purposes.

Agricultural Land Conservation:LEED-ND rewards projects that contribute to the conservation of agricultural land by prioritizing sites that do not encroach on these valuable resources. This not only protects local food systems but also maintains open space and biodiversity.

Smart Growth Principles:Infill development aligns with smart growth principles, which promote sustainable urban development patterns that reduce environmental impact, preserve natural resources, and create more livable communities. By focusing on infill sites, projects help limit the spread of urban development onto agricultural lands.

The LEED Reference Guide for Neighborhood Development discusses the importance of agricultural land conservation and how infill development contributes to this goal.

TheLEED v4 Neighborhood Developmentdocumentation outlines how selecting an infill site can help achieve credits related to land conservation.

These detailed explanations ensure a thorough understanding of how LEED-ND requirements are met in various scenarios, supporting sustainable development practices.

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.

References:

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).

For the Green Infrastructure and Buildings Credit regarding Solar Orientation, after determining maximum solar access, the project team should next focus on studying the building envelopes and daylighting opportunities. This step is essential to ensure that the construction documents accurately reflect the optimum solar orientation, which can significantly enhance energy efficiency and occupant comfort. The other options, while relevant, do not directly pertain to incorporating solar orientation into site design as effectively as studying building envelopes and making necessary adjustments in the construction documents.

For the purpose of calculating previously developed site area in LEED for Neighborhood Development, lots that are fully covered with existing buildings, hardscapes, or other impervious surfaces are considered 100% previously developed. Smaller lots, such as the 0.5 acre option, are often fully developed, making them eligible to be classified as 100% previously developed under LEED ND guidelines.

References:

LEED v4 Neighborhood Development Guide: This document specifies how to determine and calculate previously developed land for LEED certification (USGBC, LEED v4 Neighborhood Development Current Version).

LEED Reference Guide for Neighborhood Development: Provides detailed guidance on how to categorize and calculate site areas for credits related to previously developed lands (USGBC, LEED Reference Guide for Neighborhood Development).

Nonstructural roofing material can be omitted from the calculation verifying the percentage of reuse of buildings undergoing major renovation in a LEED for Neighborhood Development project. The calculation typically focuses on structural elements of the building that have a significant impact on the overall sustainability of the renovation.

Reuse Calculation:In LEED-ND, the calculation for the percentage of building reuse considers the retention and reuse of structural and significant non-structural elements during a renovation. This is to ensure that the embodied energy and materials within the existing structure are maximized, reducing the need for new materials and minimizing waste.

Exclusion of Nonstructural Roofing Material:Nonstructural elements, such as roofing materials that do not contribute to the structural integrity of the building, are generally excluded from this calculation. This is because these materials are often replaced more frequently due to wear and tear and do not represent the same level of material conservation as structural components.

Structural Elements Focus:The emphasis is placed on retaining major structural components such as floors, framing, and exterior walls, which contribute significantly to the building’s embodied energy and material footprint.

The LEED Reference Guide for Neighborhood Development provides detailed instructions on how to calculate the percentage of building reuse and what elements should be included or excluded.

TheLEED v4 Neighborhood Developmentdocumentation clarifies the definitions of structural and nonstructural materials in the context of building reuse.

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.

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.

Existing water bodies can be included as non-buildable land. Non-buildable land refers to areas where development is restricted due to natural features, environmental regulations, or other constraints that prevent construction. Existing water bodies, such as lakes, rivers, or ponds, naturally limit the possibility of development and are therefore classified as non-buildable. This designation helps protect natural resources and contributes to the sustainability and ecological health of the project site.
