    SS Credit 3: Alternative transportation


    To reduce pollution and land development impacts from automobile use.


    Option 1. Public transportation access (6 points)
    Path 1. Rail station, bus rapid transit station & ferry terminal proximity

    Locate the project within 1/2-mile (800 meters) walking distance (measured from a main building entrance) of an existing or planned and funded commuter rail, light rail, subway station bus rapid transit1 station or commuter ferry terminal.


    Path 2. Bus stop proximity

    Locate the project within 1/4-mile (400 meters) walking distance (measured from a main building entrance) of 1 or more stops for 2 or more public, campus, or private bus lines usable by tenant spaceTenant space is the area within the LEED project boundary. For more information on what can and must be in the LEED project boundary see the Minimum Program Requirements (MPRs) and LEED 2009 MPR Supplemental Guidance. Note: tenant space is the same as project space. occupants.


    Path 3. Rideshare proximity

    Projects outside the U.S. may locate the project within 1/4-mile (400 meter) walking distance (measured from a main building entrance) of 1 or more stops for 2 or more existing rideshare options2 that that meet the definition of public transportation3 and are authorized by the local transit authority if one exists.

    Option 2. Bicycle commuting (1 point)

    Provide secure bicycle racks and/or storage within 200 yards of a building entrance according to the following guidelines based on project square footage:

    • Up to 5,000 sf (465 square meters), 2 or more bicycle racks
    • 5,001–20,000 sf (466-1,860 square meters), 3 or more bicycle racks
    • 20,001–50,000 sf (1,861-4,600 square meters), 6 or more bicycle racks
    • More than 50,000 sf (4,600 square meters), 10 or more bicycle racks


    Institute 1 of the following: lockable changing areas, showers, bicycle maintenance program, or bicycle route assistance.

    For projects that are part of a multitenant complex

    A multitenant complex is a master-planned development of stores, restaurants, and other businesses; retailers may share one or more services and/or common areas.

    If bicycle racks have been provided by the development in which the project is located, the number that may be attributed to the project is determined by taking the square footage of the retail project and dividing by the total square footage of the development (buildings only). Multiply the resulting percentage by the total number of bicycle racks. If this number does not meet the credit requirement, the project should add additional spaces.

    Option 3. Low-emitting and fuel-efficient vehicles
    Path 1. Provide vehicles

    Provide low-emitting and fuel-efficient vehicles4 for 3% of the full-time equivalentFull-time equivalent (FTE) represents a regular building occupant who spends 40 hours per week in the project building. Part-time or overtime occupants have FTE values based on their hours per week divided by 40. Multiple shifts are included or excluded depending on the intent and requirements of the credit. (FTEFull-time equivalent (FTE) represents a regular building occupant who spends 8 hours a day (40 hours a week) in the project building. Part-time or overtime occupants have FTE values based on their hours per day divided by 8 (or hours per week divided by 40). Transient Occupants can be reported as either daily totals or as part of the FTE. Residential occupancy should be estimated based on the number and size of units. Core and Shell projects should refer to the default occupancy table in the Reference Guide appendix. All occupant assumptions must be consistent across all credits in all categories.) occupants.

    Provide preferred parkingPreferred parking, available to particular users, includes designated spaces close to the building (aside from designated handicapped spots), designated covered spaces, discounted parking passes, and guaranteed passes in a lottery system.5 for these vehicles.


    Path 2. Preferred or discounted parking

    Provide preferred parking for low-emitting and fuel-efficient vehicles for 5% of the total employee parking and 5% of customer parking provided for the project.


    Path 3. Alternative fuel

    Install alternative-fuel refueling stations for 3% of the total vehicle parking capacity of the site. Liquid or gaseous fueling facilities must be separately ventilated or located outdoors.


    Path 4. Vehicle sharing program

    Provide building occupants access to a low-emitting or fuel-efficient vehicle-sharing program. The following requirements must be met:

    • One low-emitting or fuel-efficient vehicle must be provided for a minimum 3% of employee FTE occupants. Assuming that 1 shared vehicle can carry 8 persons, 1 vehicle per 267 employee FTE occupants is required. For buildings with fewer than 267 employee FTE occupants, at least 1 low‑emitting or fuel-efficient vehicle must be provided.
    • A vehicle-sharing contract must be provided that has an agreement of at least 2 years.
    • The estimated number of riders served per vehicle must be supported by documentation.
    • A narrative explaining the vehicle-sharing program and its administration must be submitted.
      • Parking for low-emitting and fuel-efficient vehicles must be located in the nearest SS Credit 3 available spaces in the nearest available parking area. Provide a site plan or area map clearly highlighting the walking path from the parking area to the project site and noting the distance.

      Option 4. Parking availability

      Case 1. Projects with an area less than 75% of the total building area

      Path 1 - Zoning requirements will not be exceeded

      Parking spaces provided to tenant must meet but not exceed minimum number required by local zoning regulations.

      Preferred parking must be provided for carpools or vanpools capable of serving 5% or more of tenant employees.


      Path 2: No new parking

      No parking will be provided or subsidized for tenant employees.

      Case 2. Projects with an area 75% or more of the total building area

      Preferred parking must be provided for carpools or vanpools, capable of serving 5% of the building employees.


      Path 1 - Zoning requirements will not be exceeded

      Parking capacity must meet but not exceed minimum local zoning requirements.

      Preferred parking must be provided for carpools or vanpools, capable of serving 5% of the building employees.


      Path 2: No new parking

      No new parking will be added for rehabilitation projects.

      Option 5: Delivery service (1 point)

      Provide a delivery service for purchases made from the retail establishment.

      It is not required that the delivery service be free of charge, but the cost should not be prohibitive.

      Option 6: Incentives (1 point)

      Provide a comprehensive incentives program for employees who carpool or use alternative transportation to get to work. Three incentives must be provided for all staff upon hire.

      Potential incentives may include but are not limited to the following:

      • Transit pass subsidies.
      • Purchase of public transportation passes on a pretax basis.
      • Preferred scheduling for carpoolers. While shifts cannot be guaranteed, a reasonable effort will be made to accommodate carpooling employees’ schedules.
      • An "emergency ride home” program for carpoolers and vanpoolers who must leave work unexpectedly.
      • Preferred parking for carpools or vanpools.
      • Discounts on bicycle accessories and maintenance at local shops.
      Option 7: Alternative transportation education (1 point)

      Provide a board or computer display in the retail project, accessible to both employees and customers, that provides the following information:

      • Information on carpooling programs.
      • Transit trip planning assistance.
      • Transit maps.
      • Maps of bicycle routes and the locations of secure bicycle parking, lockers, and showers, if provided.
      • Summary of the company transportation management plan.
      • Contacts for more information.

      1For the purposes of this credit “preferred parking” refers to the parking spots that are closest to the main entrance of the project (exclusive of spaces designated for handicapped persons) or parking passes provided at a discounted price. To establish a meaningful incentive in all potential markets, the parking rate must be discounted at least 20%. The discounted rate must be available to all eligible customers (i.e. not limited to the number of customers equal to 5% of the vehicle parking capacity), publicly posted at the entrance of the parking area, and available for a minimum of 2 years.

      2For the purposes of this credit, low-emitting vehiclesLow-emitting vehicles are classified as zero-emission vehicles (ZEVs) by the California Air Resources Board. are defined as vehicles that are classified as Zero Emission Vehicles (ZEVZero-emission vehicles.) by the California Air Resources Board. Fuel-efficient vehicles are defined as vehicles that have achieved a minimum green score of 40 on the American Council for an Energy Efficient Economy (ACEEE) annual vehicle rating guide.

Comprehensive Transportation Management Plan

A comprehensive transportation management plan is one way to earn an Exemplary PerformanceIn LEED, certain credits have established thresholds beyond basic credit achievement. Meeting these thresholds can earn additional points through Innovation in Design (ID) or Innovation in Operations (IO) points. As a general rule of thumb, ID credits for exemplary performance are awarded for doubling the credit requirements and/or achieving the next incremental percentage threshold. However, this rule varies on a case by case basis, so check the credit requirements. point under SSc4.

Option 2: EV Capacity per Station

The LEED Credit Form asks for the capacity per charging station. I understand that a Level 2 EVSE provides a full charge in the range of 5 to 8 hours, is the LEED Credit Form asking for the full charge or something else?

Our project is located in a mall so we could make some assumptions about the average shoppers charging/shopping time to determine the capacity per station if LEED is not requiring a full charge. Since retails are often open longer than 8 hours, could we make further assumptions about the number total station capacity.

Tristan Roberts LEED AP BD+C, Editorial Director – LEEDuser, BuildingGreen, Inc. Dec 23 2013 LEEDuser Moderator

I think the safest assumption to make is to provide capacity in terms of the number of full charges that you can deliver while the retail space is open. 

Let's take an extreme example and say that you assumed shoppers only stay for 30 minutes, and the store is open for 8 hours. Then your capacity could be stated as serving 16 vehicles per day, but that doesn't really seem to fit the intent.

There may be a middle ground where you make some more reasonable assumptions—I think it would be up to you to make as strong a case as possible.
