NC-2009 SSc4.3: Alternative Transportation—Low-Emitting and Fuel-Efficient Vehicles

  • NC_SSc4-3_Type1_LowEmittingVehicles Diagram
  • Promote use of high-efficiency vehicles

    This credit is focused on limiting environmental impacts from automobile use. It targets commuting specifically, but also addresses company vehicle fleets, maintenance vehicles, and buses.

    If your project has substantial parking area, you may find the requirements of this credit to be low-hanging fruit, because you should easily be able to designate 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. for low-emitting and fuel-efficient vehiclesFuel-efficient vehicles have achieved a minimum green score of 40 according to the annual vehicle-rating guide of the American Council for an Energy Efficient Economy., which is one option. There are other options for compliance, all of varying difficulty and requiring varying levels of commitment from the project owner.

    Pick a path and go with it

    It’s wise to choose your compliance path early in the process, especially since some of the options require infrastructure development such as alternative fueling stations. 

    LE/FE vehicle signageMake sure that you base your choice on the likelihood that building occupants will take advantage of the resources you provide. While this is not often done, surveying occupants or prospective occupants is a good way to determine which strategy is likely to have the highest impact.

    A range of options

    Option 1: Providing preferred parking for low-emitting and fuel-efficient vehicles is by far the most cost-effective option for projects that have onsite parking managed by the building ownership. “Preferred” is defined as easy to access (such as close to building entrances), or available at a discounted price.

    Option 2: Providing onsite alternative fueling stations for 3% of total vehicle parking capacity is a bit more involved and potentially more expensive. The most readily accessible strategy here is providing plug outlets for electric cars. 

    Option 3: Providing low-emitting or fuel-efficient vehicles for 3% of FTE occupants along with preferred parking for these vehicles may be the most expensive approach to this credit. If a project already maintains a fleet of vehicles, however, then low-emitting and fuel-efficient vehicles can be substituted at no added cost—possibly even at a cost savings. 

    Parking signageOption 4: Implementing a vehicle-sharing program with provision for designated parking for shared vehicles may be best integrated into residential or campus project programming.   

    Parking is not a prerequisite

    Projects that do not provide onsite parking can still earn this credit by pursuing Option 4 and implementing a low-emitting and fuel-efficient vehicle-sharing program (many residential projects prefer this option). Projects may also earn the credit by pursuing Option 2, providing alternative fueling stations onsite.

    Signage matters

    Parking signage for this credit must typically include the terms "Low-Emitting" and/or 'Fuel-Efficient," with the only exceptions being "Zero Emissions Vehicles" or "ACEEE 40+." Signage using solely terms like "Alternative Fuel Vehicles," "Hybrid Vehicles," or "Electric Vehicles" is not sufficient, because some hybrid vehicles, etc., do not meet the LE/FE definition, and vice versa.

  • Don't double-count parking spaces

    If your project is pursuing both SSc4.3 and SSc4.4, be careful not to double-count 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. spaces allotted for those credits. The total number of preferred parking spaces must be equal to those required for SSc4.3, plus those required for SSc4.4. The same parking space cannot count for both credits (although they do not have to be distinguished through signage).

  • FAQs for SSc4.3

    Do all hybrid vehicles automatically qualify for this credit?

    No. The qualifying list rates vehicles for fuel efficiency as well as emissions. Most—but not all—hybrids meet the criteria. There are also non-hybrid cars that qualify for the credit. Always check the most up-to-date list for qualifying vehicles. The list is long and inclusive.

    Can a project pursue this credit via a combination of Option 1 (preferred parking) and Option 2 (alternative fueling stations)?

    This would probably be approved by LEED, depending on specifics, but you would need to get an official ruling—either a  CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide or LEED InterpretationLEED Interpretations are official answers to technical inquiries about implementing LEED on a project. They help people understand how their projects can meet LEED requirements and provide clarity on existing options. LEED Interpretations are to be used by any project certifying under an applicable rating system. All project teams are required to adhere to all LEED Interpretations posted before their registration date. This also applies to other addenda. Adherence to rulings posted after a project registers is optional, but strongly encouraged. LEED Interpretations are published in a searchable database at usgbc.org..

    How should the signage read for preferred parking spaces?

    Neither USGBC or GBCI has provided a mandatory signage design, but there has been consistent guidance indicating that one or more of the following terms must be on the sign:

    • Low-Emitting
    • Fuel-Efficient
    • Zero Emissions
    • ACEEE 40+

    Some project teams have struggled with this because they think it does not clearly convey the concept to occupants, but nonetheless, this has been the pattern of review comments from GBCI. For projects that want to use additional terms, they may use one of more of the above terms, in combination with any of the following terms.

    • Alternative Fuel Vehicles
    • Hybrid Vehicles
    • Electric Vehicles

    These terms are not sufficient on their own, however, as not all hybrid vehicles are low-emitting, for example.

    For electric vehicle charging stations, how are the parameters established for fueling capacity?

    Typically credit is given for each available preferred parking spot with a separate charging plug. If a charging station provides a fast charge and the project wants to have that reflected in its credit calculations, then the project team should provide evidence from both the charging system manufacturer and the building or parking management showing that the logistics of allowing multiple vehicles to share a single charging station will be managed accordingly.

    I am working on a project with no parking spaces allocated. Can I earn this credit?

    Yes, some projects have earned this credit with a regional car-sharing program that locates a publicly accessible car share vehicle adjacent to the project site.

    Our project is outside the U.S., and the LEED-approved ACEEE Green Score and CARB ratings and classifications don't apply to many vehicles. Is there another approach that is accepted?

    Only in Brazil, where projects can benefit from the approval of a regional program in LEED Interpretation #10230. GBCI's policy is that until a Global alternative compliance path (ACP) or LEED Interpretation comes out, proposals for non-standard approaches must be evaluated on a case-by-case basis by individual review teams. This means that some LEED projects may be able to create a successful approach, and some might have difficulty—a situation that is consistent with what LEEDuser has heard about LEED review comments.

    Should I consider motorbikes and parking spaces for them under this credit? What about fleet vehicles?

    Fleet vehicle and storage spaces—for example, spaces for school buses, military vehicles, rental cars, or tractor trailers—are not counted in the number of total parking spaces, but commuter spaces are counted, including those dedicated to atypical vehicles such as motorcycles.

    According to GBCI, an "atypical" vehicle used for commuting, such as a motorcycle, should be counted the same as a "standard" passenger car parking space.  The amount of preferred parking provided should be distributed evenly among the various parking space types.

    For example, if 40% of the project’s parking is for motorcycles, 60% of the total parking is for standard passenger vehicles, and 10 preferred spaces are required to earn the credit, the preferred spaces should be distributed such that four preferred spaces (40%) are provided for motorcycles and six preferred spaces (60%) are provided for passenger vehicles.

Pre-Design

Expand All

  • Pick the best of the four compliance path options for attaining this credit:

    • Option 1: Provide either preferred parking for low-emitting and fuel-efficient vehicles for 5% of total parking capacity or a discounted parking rate (at least 20%) for low-emitting and fuel-efficient vehicles. 
    • Option 2: Install alternative fueling stations for 3% of parking capacity.
    • Option 3: Provide low-emitting and fuel-efficient vehicles for 3% of FTE building occupants with designated preferred parking for these vehicles. 
    • Option 4: Institute a low-emitting or fuel-efficient vehicle-sharing program.

  • Costs for each option are very different, and occur at different times. Don't forget to factor in infrastructure development, administration costs, procurement costs, and maintenance and upkeep costs. For example, installing fueling stations is much more expensive than providing preferred parking spaces with signage.


  • Simply providing preferred parking for low-emitting and fuel-efficient vehicles is the easiest way to comply with this credit. It is also a low-cost option.   


  • Consider the feasibility of each option based on your site location. Is your project located in a dense urban environment where most people commute to work via mass transit, or are you in a suburban or rural area where most people drive to work, and may appreciate a vehicle-sharing program? Also consider things like whether there are alternative-fuel vehicles used by occupants or whether occupants tend to use low-emitting and fuel-efficient vehicles. Are HOV (high-occupancy vehicle) lanes available? These types of questions will help to determine an appropriate approach to this credit.  


  • Consider the preference of building occupants so as not to dedicate resources to programs or infrastructure that will remain idle and not serve their intended audience. Is the organizational culture such that employees would appreciate such amenities? Depending on the building type, building occupants can be surveyed to assess the demand for amenities relating to low-emitting and fuel-efficient vehicles. If you are planning on providing alternative-fuel refueling stations, assess what kind of fuel is preferred.


  • If the project team is committed to creating a comprehensive transportation management plan to qualify for an Exemplary Performance point through IDc1, dedicating the resources upfront to develop and implement a vehicle-sharing program makes sense, as it will be folded into the broader transportation plan.


  • A residential building in a dense urban area that does not have parking facilities may favor a vehicle-sharing program as a way of attracting new tenants and earning the credit at the same time. 


  • The same parking space cannot contribute to both SSc4.3 and SSc4.4 by being designated for low-emitting and fuel-efficient vehicles (SSc4.3) and carpools or vanpools (SSc4.4).   

Schematic Design

  • Refer to the California Air Resources Board Zero Emission Vehicles (ZEV) list and to the American Council for an Energy Efficiency Economy (ACEEE) annual vehicle rating guide to determine which vehicles are classified as low-emitting and fuel-efficient. (See Resources.)


  • Hybrid and electric vehicles are not the only ones considered low-emitting and fuel-efficient. Many common gasoline vehicles with mileage efficiency of 21 mpg and above also meet that description depending on their make, model, fuel efficiency and emissions. 


  • “Preferred parking” refers to parking spaces near the building entrance or to discounted parking rates (minimum 20% discount), which must be offered to all eligible parking customers. Preferred parking is separate from, and should not be confused with disabled parking. Preferred spaces should be broken out evenly for the various types of parking spaces that are provided in the project—automobiles, trailers, compact cars, etc. Spaces for vehicles integal to the facilities process such as fleet or "inventory" vehicles can be excluded from calculations.


  • In a parking-garage, look to the location of disabled parking spaces for guidance on what is “preferred.” This may be on the lowest floor, or it may be closest to stairwells or elevators spread out over multiple floors.   


  • If it is not possible to reserve designated parking spaces close to the main entrance for LE and FE vehicles, comply by offering discounted rates for parking through coupons, vouchers, or other similar incentive programs. 


  • Some past projects have been able to designate preferred parking spaces in off-site parking areas attributed to the project that were not within the LEED scope or boundary, as long as they were within one-quarter mile of the project's main entrance or serviced by a shuttle. These preferred spaces had to be reserved for LEED project building occupants only. Project teams with similar circumstances need to consult with GBCI to see if taking a similar approach is allowed.


  • Since there are no “LEED police” to check compliance with parking rules after a project’s completion, it is the project owner’s responsibility to meet the intent of the credit throughout the operations phase using the honor system. Some owners choose to screen occupants’ cars and distribute stickers to those that are allowed to park in designated preferred-parking spaces.


  •  Option 1: Provide Preferred Parking


  • Calculate the total vehicle parking capacity of the site and allocate 5% of it for preferred parking spaces for low-emitting and fuel-efficient vehicles.  


  • Calculations should be based on the parking spaces associated with the building pursuing LEED certification plus any additional parking included in the LEED boundary. Options 1 and 2 relate to total parking spaces included onsite within the LEED boundary while Options 3 and 4 relate to vehicles for project occupants. If parking for the building is offsite, it must be included in credit calculations. If some of the parking is onsite and some offsite, confirm the appropriate approach to the situation with GBCI.


  • Alternatively, if the LEED boundary includes a multi-story garage that serves multiple buildings in addition to the LEED project, all the parking spaces within the LEED boundary must be included for calculations even if only a portion of the parking area is expected to be for the project building’s use. 


  • If designating parking spaces is not desirable, the credit can be achieved by providing a discounted parking rate of at least 20% for low-emitting and fuel-efficient vehicles.  


  • Option 2: Refueling Stations


  • Incorporate alternative fueling stations into your plan early in the design stage. 


  • Calculate the total vehicle parking capacity of the site and install alternative fuel stations for at least 3% of that capacity. 


  • Fueling stations can be as simple as an electric-car charging outlet in a parking garage, but they must be designed to support street-legal, long-range vehicles (not electric golf carts, for example).


  • If installing a electric car-charger, install a 240V conductive power supply (or inductive charger). The emerging market for electric vehicles is expected to require J-1772-compliant outlets, which need a 240V power supply.


  • To assess the demand (potential or future) for alternative fueling stations, conduct surveys to determine the alternative fuel most likely to be used by future building occupants. Consider polling future building occupants via email or a paper survey.


  • Research local code requirements and standards that may apply to installing fueling stations on your project site, including building, fire and electrical codes. Also look into relevant equipment, upkeep, and maintenance of refueling stations.  


  • Project teams should carefully consider available technologies and different fuel sources before installing fueling stations. There are also legal, technical, and safety issues to take into account and deal with early in the process: 

    • Look at the kind of liability that is associated with installing these fueling stations on your project site. 
    • Look at fuel availability and compare the price and requirements of installing fueling stations for different kinds of fuels. Cost will vary depending on the type of fuel and the complexity of installation. 
    • Consider the fueling and charging characteristics of each type of fuel that you are considering. Natural gas fueling facilities, for example, consist of one or more gas compressors, a compressed gas storage tank, and gas dispensing equipment. If you are using another kind of alternative fuel, the equipment requirements may be different, affecting cost and feasibility. 
    • Consider health and safety aspects that may be linked to each alternative fuel option. For example, electric vehicles with batteries should generally be charged in a well-ventilated area.  
    • Consider how easy or difficult it will be for operations personnel to maintain the stations.

  • For liquid fuels like biodiesel and ethanol, provide storage and safe handling procedures for fueling stations. Research a variety of fuels that may be made available to the project occupants. 


  • Providing alternative fueling stations may have significant cost implications, though the popularity of alternative-fuel vehicles is slowly working to make them more cost-competitive. 


  • The project owner may choose to sell the alternative fuel to the public in addition to providing it to building occupants.


  • The costs of installing and maintaining alternative fueling stations should be weighed against the anticipated use of the facilities and the environmental benefits that can accrue from it. 


  • Option 3: Provide Low-Emitting Vehicles and Preferred Parking for Occupants


  • Calculate the total number of FTE occupants in the building to determine the number of low-emitting and fuel-efficient vehicles to purchase as well as the number of preferred parking spaces to provide. 


  • To calculate FTE occupants, use a standard eight-hour occupancy period. An FTE, therefore, has a value of one (8 ÷ 8). Each part-time staff occupant has a value of the number of hours of occupancy divided by eight (e.g., 4 ÷ 8 = ½ FTE). It follows that the total number of staff FTEs equals the total number of staff hours divided by eight.


  • Maintain consistency in the number of FTEs across all LEED credits.


  • Refer to the ACEEE list for eligible vehicles. (See Resources.)


  • Simple electrical outlets do not constitute vehicle-charging stations. Electrical charging stations have distinct hardware for vehicle charging. If providing electrical vehicles for the fleet, these charging stations should be available to those vehicles. 


  • Allowing adequate lead time is important in this option, as alternate-fuel vehicles may take longer to order and purchase. Communicate with procurement officers as early as possible in the planning process. 


  • For companies that provide vehicles for employee use, consider “greening your fleet” by purchasing vehicles qualified as low-emitting and fuel-efficient. Project teams should carefully consider available technologies and different fuel sources before purchasing vehicles. 


  • The setup costs for this option may be considerable. 


  • Research tax incentives offered by federal, state, or local governments for purchasing alternative-fuel vehicles. This could help offset some of the initial costs. 


  • Option 4: Vehicle-Sharing Program


  • Implement a vehicle-sharing program in which one low-emitting or fuel-efficient vehicle is provided per 3% of FTE occupants. This works out to one vehicle for every 267 FTE occupants, assuming that one shared vehicle can serve eight people. (The number of vehicles required equals the total number of FTEs divided by 267—see the Documentation Toolkit for a calculator.) At a minimum, one vehicle must be provided, regardless of the number of occupants in the building.  


  • All cars included in the vehicle-sharing program must be qualified as low-emitting or fuel-efficient by ACEEE. 


  • The program also must have a minimum two-year contract and designated preferred parking for the shared vehicles. 


  • Try negotiating a special contract with a vehicle-sharing company for low-emitting or fuel-efficient vehicles.

Operations & Maintenance

Expand All

  • Continued compliance with the spirit of this credit is largely based on the honor system and the integrity of building management and users. To ensure that preferred parking policies are respected, consider the following strategies:

    • Wherever preferred parking is provided, post signage that identifies preferred parking or alternative-fuel stations.
    • Signage can be as noticeable or discreet as desired, but must clearly demarcate preferred spaces as such. 
    • A sticker program can be implemented to identify cars that qualify to park in preferred parking spaces. 
    • Provide information about the parking program via appropriate channels for your project.
    • Post information about the parking program in entryways and in public areas. 

  • Make sure that operations and maintenance personnel (or a vendor, if involved) are set up to maintain the alternative fueling stations. Provide them with all required information about safety and maintenance procedures.


  • Building staff will also spend time administering the various parking programs: preferred parking, discounted parking, or vehicle-sharing. Procedures and policies for their use must be developed, along with enforcement mechanisms.

How many signs are required for preferred parking?

I am working on a project in California. CALGreen, the state green building code section, requires that a certain number of parking stalls be designated as "CLEAN AIR" spaces. This language is required to be painted on the ground. In our LEED design review, the reviewer said "The documentation does not confirm that the preferred spaces are reserved for low-emitting and fuel-efficient vehiclesFuel-efficient vehicles have achieved a minimum green score of 40 according to the annual vehicle-rating guide of the American Council for an Energy Efficient Economy., as required. Instead, the spaces appear to be reserved for clean air vehicles." (which would be different?) and asked for signs on posts with the standard language: LOW-EMITTING
AND FUEL-EFFICIENT VEHICLE PARKING ONLY
We have 16 such spaces. How many post signs do we need? If the city was willing to approve the LEED language painted on the ground, in lieu of CA language, would that be sufficient?
It's just a lot of signage, and expensive.

Signage matters and alternative fueling stations

We would like to implement charging stations for electrical cars into our project. The credit talks about signage matters. I understand that signage is only required for option 1, 3 and 4 though not for the parking spots with electrical charging stations?

Scooter Parking

I have a athletic project on a college campus where most student athletes using the facility would arrive via scooter. There is no new parking for the project (parking is offsite, adjacent to the site) but if we were to provide parking for these scooters onsite would we be able to get credit 4.3? Would they have to be electric??? Just seeing if someone has been down this road before.

Thanks,

Mark

You could always try and see, but that approach does not seem like it fulfills the intent of the credit, which is to reduce the environmental impact of automobile use to/from the site. I think the more straightforward approach is to look at providing 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. in the offsite lot that the athletes use, even if it is outside of your LEED project boundary.

Even if they were all electric I don't think it fits in very well with this credit even though it is a good thing to do.

See LEED v2.2 Interpretation #1959:

"While the provision of scooters for employee use is a laudable strategy, it does not meet the intent of the SSCr4.3. There are concerns that scooters do not have the same emissions control requirements as low-emitting cars and that, due to safety worries, some employees will be unwilling to use the scooters even in good weather. The project team is encouraged to explore the use of a car sharingA system under which multiple households share a pool of automobiles, either through cooperative ownership or through some other mechanism. service or the purchase of electric and/or low-emitting cars to meet the credit intent. Another possibility would be to apply for an ID credit for a comprehensive traffic demand management program, of which scooters could form a part. Applicable Internationally."

Hi Ellen,
Thank you very much for your instruction. I found CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide stating 240V receptacle was acceptable, after I posted the former question. Actually we use 100/200V receptacles in our country. Do you think 200V receptacle is acceptable for this credit compliance?

It's not clear to me what I have to upload onto the form for option 1. It states: upload a credit-specific site plan showing all parking areas, highlighting any 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., including signage details.

I usually upload either a dimensioned drawing provided by the signage consultant or a sample sign from another project owned/operated by the same owner in the case of a university or healthcare system (for example). A good first step would be to speak with your client about what he/she intends to install and then from there, determine who can provide you specifics on signage.

Interpretation #10202

There is an interpretation - not that new but recently enforced - that has come to my attention on the Core & Shell page that I wanted to share over here on NC. According to interpretation #10202, it is no longer acceptable to split up 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. spaces among levels of a parking garage - even if they are closest to the vertical circulation. Now, all preferred parking must be on the closest level to the building entrance unless it can show that the walking distance is greater than the driving distance to these spaces. Does anyone else think that this is just nit-picky to the point of ridiculous? I really don't see how forcing all of the preferred parking spaces to be on the ground level adds value to a project. It seems just as logical to break them up and have them closest to the stairs/elevators. This is going to lead to a lot of irritated owners who will have the first level of their parking garage mostly empty on any given day. Not to mention that this is yet another example of changing the rules in the middle of the game.

It is more short sighted than nit picky to me. I can see how in many cases the ground floor is preferred (convenience, less driving). But I'm dealing with sick patients who would much prefer to be close to a building entrance on the floor that they are getting treatment. This will take me out of a credit rather than put me into a credit.

It's surprising, as ADA spaces are typically distributed at all levels of a multi-level garage and not all placed on the level closest to the entrance. As much as the criteria for "preferred" is not going to be identical to the criteria for accessibility, observations suggest that most people prefer to drive one more level to park closer to an elevator or stair, whether its because they are carrying things, concerned about safety, or trying to minimize their walking distance. "Preferred" is a fairly subjective term, and while it's helpful to get more clarity on what GBCI is looking for, it seems overly prescriptive.

Take note that the LI states, "The location of 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. for structures with multiple entrances can be further evaluated during project review. For LEED submission purposes, the project team should provide a narrative with a detailed description of the building." I believe they understand there are specifics of each project that would make it more appropriate for the spaces to be distributed throughout the levels. The project that was asked about in the LI had everyone traveling to the first floor of the garage and then traveling to the main entrance of the building. It doesn't seem to have completely ruled out the option of distributing across levels as long as a project specific narrative describes why this is more appropriate for the project.

To me, the way that it is worded just sets the stage for inconsistency and uncertainty when attempting to locate preferred spaces somewhere other than the level closest to the main entrance. It seems that this ruling has recently been cited consistently on projects that have tried to break up 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. among levels, so I can't help but assume that it has become a standard rule. The most important thing to me as the LEED administrator is that I can't say with any degree of confidence that this approach will work any more. Waiting to just submit and see is not the best option when you are counting on getting this credit and not being able to provide a concrete direction makes me look like I don't know what I'm doing. This also sets the stage for one reviewer approving a strategy that another denied, which makes us all look bad.

I must agree with Ellen about the Admin role. I am in the SD phase of a CS building, and we are trying to solidify the parking arrangements. Our building will be a typical office, commercial building with multi-level underground parking. It seems most logical to the team to locate the 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. in the same locations of the ADA spaces.
While it may seem like space designations can be easily changed, that is not always the case. The building owner is in negotiations with a major tenant. Parking availability is one of the items in negotiations. If the owner promises the tenant spaces that will have to be changed later based on a LEED review comment, it could negatively impact all parties, and additionally reflect poorly on the LEED competency of my and my project team.

Any additional clear guidance on preferred parking locations would be much appreciated.

I have a great example of how this is problematic....we have a big developer client who is very upset about this change. They will now have to put all 62 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. spaces on ground level, which is not only inconvenient for employees who will actually have to walk farther to get to the building entrance, but it also means that the entire first level is dedicated to preferred parking for LEFEVs, which is a tough sell when you are trying to attract potential tenants. We had a call with GBCI to address this issue and they cited the caveat that each project will be evaluated on a case by case basis and suggested a detailed narrative explaining our approach. So that is exactly what we did when submitting our design review. To no one's suprise, the credit was questioned citing LI #10202 and we were told that we must adhere to the formula of driving plus walking distance. It was very clear that the reviewer was not evaluating on a practicallity standpoint, but was just checking a box on a list. This LI is ridiculous - it is making the credit harder for the sake of being harder and is adding zero value from a sustainability standpoint.

Signage translation

Hi,
In our project we're reserving prefered parking spaces for low-emitting, fuel efficient and carpool vehicles. The signage would be painted on the floor of the parking space. We think that the terms low-emitting, fuel efficient and carpool should be translated to Catalan or Spanish, since is the local lenguage, is there any inconvenience? or should this sign be exclusively in english?

Interesting question Albert. Common sense tells me that Spanish or Catalan would be more appropriate to your project, but experience with LEED reviewers tells me that common sense does not always prevail when it comes to the letter of the law. In reading the FAQs above, it sounds like international projects are evaluated on a case by case basis in terms of verbaige. If you need to know for sure, this may be a good candidate for a CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide. Or if you have the luxury of time, you could submit it with the Spanish verbiage and see what they say.

Preferred Parking - defined

Hello LEED Community! My first question for everyone.
We have had preliminary review comments returned to us, and one Technical Advice comments was regarding the location of our 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. Spaces to meet LEED definition of Preferred.
1.How does one measure "closest" to Main Entrance? Is it measured from each space, or from the center of the bank of spaces we provided?
2. Is that measurement taken as a direct "as the crow flies", or along the path of travel (ie, thru landscape islands, or along sidewalks)

Thanks much for any assistance you could provide.

Lee, I am not aware that there is a definition with the level of technical specificity that you're looking for. Maybe if you shared what the review comment was about, we could help advise.

From your questions, I wonder if you have provide a row of preferred spots in which some spaces are close to the entrance, but some spaces in the row are farther than non-preferred spots. I think this would lead a reviewer to question the plan.

Thanks Tristan.
"The location of all of the designated spaces does not appear to meet the LEED definition of preferred, as required. Preferred spaces are those spaces located closest to the main entrance of the project (exclusive of spaces designed for handicapped)"
Our original submission had a quantity of spaces that far exceeded the minimum, however, at the Owners request a small portion of these were located so that an adjacent building outside the LEED boundary could benefit. (we have since removed these spaces) The remainder of the spaces are in blocks of 5 with the block thats closest to the entrances. Technically measuring spaces would mean 2 spaces from several rows are 'closer'.

Discount Parking Rate

My project is on a college campus, the University has selected discounted parking rate as the compliance path for this credit. 20% discount will be offered to any student/staff with a LEFE vehicle.

1. does anyone know if putting a statement in the parking section of the student handbook meets the intent of "publicly posted"? i read something that stated it has to be posted at the entrance of the parking area.

2. does anyone have an example of acceptable verbage for this statement?

Hi Norma, I found an example that might be helpful for your research. The Kroc Center in Quincy, Illinois uses a parking sign in their parking lot to distinguish regular parking spots from reserved parking spots for employees driving low emission or fuel efficient vehicles. Maybe a good way for you to distinguish low emission or fuel efficient vehicles with your company is to color-code your parking permits so that only specific color-coded permits are allowed to park in the designated low emission/fuel efficient parking spots. Please follow the link for further reference: http://quincyjournal.com/emissions-favoritism...what-a-kroc!.html

Hi Norma, I did a little more research into what would fulfill the "publicly posted" signage for the discounted parking rates. Although I could not find any definitive answer, I think that the USGBC stays pretty vague on what constitutes an appropriate "publicly posted" sign for credits such as discounted parking rates in order to prevent the rating system from becoming to uniform or prescriptive. I may be wrong but I think it would be beneficial to not only publish the discounted parking rates credit into the student handbook but also place a large sign at the entrance of the parking area informing the students of the incentive.
I too am interested in getting a more definitive answer to this question so I'll keep checking back for other user posts/updates.

I appreciate the feedback. because these are residential buildings on campus, the only "users" of the building are those that live there, so i think i could argue that for this LEED project, putting it on the website and in the student handbook would be sufficient. for academic buildings, i think a sign would be appropriate, since a variety of students would visit have classes in the buidling and could take advantage of the discount for the semeseter if they drive a LEFE vehicle. i think we will try it this way, i will let you know how it turns out.

No new parking, can we still achieve Option 1?

The project I am working on is a new facility on a pre-existing campus. There are is no new parking added and all new employees are expected to find parking spots on their own.

Since there is no new parking, we are eligible for SSc4.4 but how would we go about achieving SSc4.3 in this situation? It's possible to work with the campus owner to designate X amount of spaces 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. for LE/FE vehicles but I'm not sure how many are appropriate.

The project site has no direct parking spots included in it's LEED boundary, how should this be framed to the review team? Essentially, I'm nervous that they will want us to provide 5% preferred parking for the entire campus (which we don't control at all). We are able to petition the site owner for a couple spots near the building but there is no way we will get 5% of the hundreds of pre-existing spots.

Eamon, you may be able to use zoning calculations from your local jurisdiction to estimate how many parking spaces you would be required to provide for this building if it wasn't on a campus. You could then take 5% of the zoning required number. I have had success with this approach, but the specifics of every project are different. Be aware that in cases like this it is required that these spaces would then need to not only be reserved for LEFE vehicles but also clearly state that they are reserved for LEFE vehicles visiting the LEED certified building. However, in some campus situations this does not fit into the standard operations of the campus (e.g. a zoo where a person visiting the "campus" is not just visiting the LEED certified building). Hope this helps.

Other thing, the 5% of the total parking is regarding 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. parkings or including the visitors parking wih FTE also.

3% of the total vehicle parking capacity for a complex

When calculating “3% of the total vehicle parking capacity of the site” as per LEED NC 2009 SSc4.3 Option 1, can we use the total parking capacity associated only with our project program and associated LEED scope of work?

The project entails a renovation and addition to a public library that is part of an existing community centre complex. Included in the scope of work is an extension to, and resurfacing of the existing parking lot that services all of the facilities on the site including the public library. Because we are using the site of the existing parking lot of the community centre for the addition to the library – we are 'reshuffling' existing (community centre) parking spaces in addition to adding the required spaces for the increased library area.

We believe we would meet the intent of this credit to base the 3% calculation for SSc4.3 on the parking spots required by the library only, as outlined by the municipal bylaw. While the LEED project boundary definition includes 105 parking spaces due to the extent of work – including the relocation of existing parking spaces - only 32 parking spaces have been alotted by the City as being part of the Library program and are based on the municipal by-lay of 2.5 spaces / 100 m2 of Gross Floor AreaGross floor area (based on ASHRAE definition) is the sum of the floor areas of the spaces within the building, including basements, mezzanine and intermediate‐floored tiers, and penthouses wi th headroom height of 7.5 ft (2.2 meters) or greater. Measurements m ust be taken from the exterior 39 faces of exterior walls OR from the centerline of walls separating buildings, OR (for LEED CI certifying spaces) from the centerline of walls separating spaces. Excludes non‐en closed (or non‐enclosable) roofed‐over areas such as exterior covered walkways, porches, terraces or steps, roof overhangs, and similar features. Excludes air shafts, pipe trenches, and chimneys. Excludes floor area dedicated to the parking and circulation of motor vehicles. ( Note that while excluded features may not be part of the gross floor area, and therefore technically not a part of the LEED project building, they may still be required to be a part of the overall LEED project and subject to MPRs, prerequisites, and credits.). We would provide 3% of refuelling stations for the 32 Library parking spaces. We are not adding parking spaces to the Community Centre.

Does that approach meet the intent of this credit?

I think you are in a gray area between the number of parking spaces in your scope of work and the number of spaces serving your LEED project. It is hard to say without seeing the layout of these spaces and determining if there is a clear case to only include the 32 spaces. The conservative approach to ensure that you get this credit is to provide for 3% of the 105 spaces. However, if it is very apparent that the additional 73 spaces are far enough away that they would never be used by the library occupants, it may be worth a shot.

Utilizing the car2go program to satisfy vehicle-sharing option

I am working on a mixed-use residential project that has no parking other than street parking. The location is very centralized and to promote a car free lifestyle, the owner is offering tenants a break on the initiation fee for the car sharingA system under which multiple households share a pool of automobiles, either through cooperative ownership or through some other mechanism. program car2go. This program, which is active in a handful of US cities, allows access to 200+ Smart Cars which can be picked up and dropped off at any time or location by members. The car locations are found by logging into the car2go site on your computer or by using a smartphone app, these are both updated every couple of minutes.
Since the cars being utilized by car2go are Smart Cars, it does not meet the required 8 person provision, but there is a likelihood of a number of available vehicles surrounding the project site at any one time. Has anyone used this or a similar car sharing program to meet the requirements of SSc4.3? If not, could it be a legitimate ID credit?
Thanks very much!

Discounted Parking for SSc4.3

It is understood that per SSc4.3 Option 1 within LEED v2009 you can offer discounted parking spaces at a 20% discount for vehicles that are low-emitting and fuel efficient per the referenced standards. We have a campus project whereby there is a campus policy that all fuel efficent and low-emitting vehiclesLow-emitting vehicles are classified as zero-emission vehicles (ZEVs) by the California Air Resources Board. automatically get the 20% discounted parking rate, however the the campus only offers this to students as staff does not pay for parking. The question then is since the project is a student housing building and therefore no staff whatsoever, will the campus parking policy meet the requirements of the Credit per option 1? It seems like it should but want to be sure.

Patrick, sounds to me as though if only students have access to this parking, and they get the dicount for LE/FE, then it meets the LEED requirements.

International Project - Signage issues

Our project has been denied this credit because we do not use the exact verbage required for the signage. Our project is in Sweden and parking signage is required to use traffic regulatory approved signage from the municipality. This signage specifies (when translated) to green car. As using signage "low-emitting and fuel-efficient" vehicles is not really applicable in Sweden as "green car" innately means LE/FE. These parking spaces for 'green cars' follow European emission standards that don't follow the ACEEE guidelines.

Have other European projects encountered similar issues? How have you proved that these parking spots are still compliant?

We are thinking of conducting a comparison of ACEEE and Swedish legislation (aka what it means to be a green car in sweden) to prove compliance, but this will be alot of work.

Jaida, this credit is simply one of those areas where the credit language hasn't caught up all the international locations where the credit is being used. See the FAQ above for a related issue. You would need a CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide, most likely, to deal with this.

Can we have it both ways?

We have a commercial building - a single user - and 90 parking spaces in all. We would need 5 LEV spaces or 3 alternate fueling stations The owner was going to put in 2 electrical vehicle charging stations. Can we achieve compliance by adding 3 LEV spaces? Would we need to limit the charging station spaces to LEVs?
In truth, this approach is probably the best way to serve this particular population.

Hi Susan,
I believe that there is some discussion on this approach further on down the discussion forum - if memory serves, the consensus was that a CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide is the only way to know for sure. If it were me, I would just submit it in the design phase and see what comes back. I think you have a good chance as this approach appears to fulfill the intent of the credit. Let us know what happens!

Car Share on Campus - reserved for building occupants only?

I seem to remember a requirement somewhere for the Car Share option that for a campus setting, the vehicles must somehow be reserved for use by the LEED building occupants only. Now I cannot find that requirement anywhere....
Did it ever exist? Did it go away? Thanks.

Alternatively, maybe someone can help me with this car share question, which is why I'm asking:
The client is a large university with an urban campus, with buildings all over the city. They are looking to use their existing zipcar program to achieve SSc4.3, Option 4. There is no parking at the building, so the zipcars are located in a central lot, and are available to the entire campus (staff, faculty, students).

My guess is they would have to either
a) have additional qualifying zipcars somehow dedicated soley to this building's occupants, OR
b) treat this as a campus credit, which would entail vastly increasing the quantity of zipcars in order to meet the 1 car / 267 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. requirement.

In other words, they must use the entire campus FTE (i.e., all potential users) when calculating the cars required, or dedicate use to the building.

Am I correct? Thanks!

Hi Erica,
I am not sure if this was based on an interpretation or if it is one of those "phantom" requirements, but I have had pretty consistent review comments stating that the car share cars (or reserved spaces for that matter) must either be reserved for the specific LEED project or there must be enough cars to supply the whole campus. I'm guessing that this is an effort to eliminate the potential for double dipping with future LEED projects on campus.

For your specific project, I think that either one of your A or B options would work. Also keep in mind that if there is no parking as part of your project scope, the reviewers are going to want to see your zipcars parked in the closest available lot to your site.

Thank you Ellen -
I honestly don't remember where I think I previously saw that requirement... and I haven't been able to find it again.
Thanks for the feedback -- that pretty much confirms my expectations, written requirement or not.

SSc4.3 & SSc4.4: Rounding to the 5% requirement

Our project was recently denied both of these credits on not meeting the 5% requirement. The project has a total of 62 parking spaces out of these spaces 3 spots were alloted to LE/FE vehicles and 3 spots were alloted to Carpools and Vanpools. When we originally ran the calculations 5% of 62 = 3.2. We rounded to the closest full number and provided 3 spots for both credits. On the form 3 of 62 = 4.9%. Both of these credits however were denied on not meeting the 5% requirement. Has anyone else experienced something similar? When we originally ran the calculations for both of these credits I remembered reading the LEED book very carefully and checking any possible addenda or CIRCredit Interpretation Ruling. Used by design team members experiencing difficulties in the application of a LEED prerequisite or credit to a project. Typically, difficulties arise when specific issues are not directly addressed by LEED information/guide's for this credit and could not find anything that addressed this matter.

Unfortunately, the credit requires a minimum of 5% of spaces reserved so you have not fulfilled the intent of the credit - you must always round up. There is a tread about this dating back to April of 2011 and I also believe that it is addressed in the Interpretation database.

Ellen, thanks so much for the quick response.

Now that the credits have been denied as part of the final review, would there be a way for the project to earn this point back? Would we have to provide 1 additional spot (one for LE/FE and one for HOV) and then appeal the credit?

Yes, you would need to provide a total of 4 spaces for LEFEVs and 4 spaces for carpooling vehicles in order to meet the intent of both credits. If you are willing to do this, you will have to appeal both unfortunately ($500/each).

EV Charging Station Monitoring

I was told by a EV Charging Station manufacturer that LEED is revising their standards to require monitoring equipment be included on the units (to track usage, etc). Is this true? Is so, when will this be implemented?

The current draft of LEED v4 contains a requirement that charging stations "Be networked or internet addressable and be capable of participating in a demand-response program or time-of-use pricing to encourage off-peak charging," but LEED v4 is currently not expected to be out before 2013, and this requirement would not effect LEED 2009.

Site with no parking lots - LEED ND Project

Our project is located into a LEED ND. When designing the Neighborhood, the amount of parking lots was established in accordance to local regulations, and this parking lots where located among the streets of the neighborhood.

Our project site is surrounded by 4 streets, and two of them are plenty of parking lots. In total there are 21 parking lots adjacent to the project

Nevertheless, our Project site doesn't include those parking lots since the streets belong to the owner of the ND. So, our project does not include the construction of any parking lot at all, because they are already built.

Q1: In order to achieve SSc4.3, can we demonstrate that 5% of the adjacent parking lots will be designated to LE/FE vehicles?

Q2: In order to achieve SSc4.4, since we are not providing new parking I guess that the credit should be achieved. Am I correct?

Thanks in advance for your help!

Gaston - I have been able to successfully use the approach you have described above. The direction we have seen from reviewers is that you must include any parking that will serve your building in SS4.3 calculations, but you can claim the No New Parking option of SS4.4 if there is no parking being constructed in your project scope. Using the adjacent lots for SS4.3 seems like a reasonable solution as long as it is apparent that those lots can meet the vehicular demand of your building.

Single parking space for the project.

For our current project we are allocating One parking space for the project. This space will be indicated as an accessible space. Think we can also indicate this as a low-emitting/fuel efficient vehicle space also for the SS Credit 4.3?

I think the bigger issue is whether you can add a restriction to a required ADA parking space legally.

10 Point Maximum?

We are utilizing LEED v2009 Retail NC for a major remodel/addition for a bank branch. We have no new parking, are installing bike racks (with covered racks and employee shower/changing room), and the entry sits withing 400' of more than three bus line stops. This seems to give us 10 points (3, 1 & 6 points respectively). The form says a maximum of 10 points is achievable.
It seems a bit dumb to ask this question but I want to make sure I am reading this correctly and not missing anything. Besides the added environmental benefits, can you think of any reason LEED points may increase if we were to also offer an electric vehicle charging station, incentives for employees to take public transportation (or bike/carpool/etc) and/or the branch helps with trip planning?
I can't find an EP point for this credit.

Caroline - you raise a good question. I am guessing that you could not get an additional point for the EV charging stations because that is already accounted for as one of the options for SSc4 and you have already hit the 10 points for that credit. What is not as clear is whether 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 is available in this category as it is in BD+C for "instituting a comprehensive transportation management plan that demonstrates a quantifiable reduction in personal automobile use." If this kind of plan is something that the team is considering doing anyway, I would suggest submitting it and seeing what the reviewers say. However, if the extra effort is only to earn the point, you may save yourself a considerable amount of time submitting the question to GBCI first.

Thank you for the feedback. We'll still include the EV charging station because the Owner wants one for their staff but I won't be placing it anywhere on the credits. We won't be completing the TMP but it does seem if we were to do one we could achieve EP (assuming it met the reviewers requirements).

So the nature of the program is to "create" fuel-efficient vehiclesFuel-efficient vehicles have achieved a minimum green score of 40 according to the annual vehicle-rating guide of the American Council for an Energy Efficient Economy., which they will store inside the garage facility for continued research and testing.

Or, since there will be 240V and 480V charging within the building, could that count for Option 2 instead? Thank you for your help!

Because you are proposing a somewhat non-standard path to achieving this credit, I am not sure you will find a definitive answer outside of a credit interpretation request (or you can just try it and see). It is unclear from your description if the project also includes parking for employees/students/staff. If so, then I'm guessing that the charging stations and/or FE vehicles need to be available to them as well in order to have a convincing argument.
