Reduce the impact of automobile use
This relatively straightforward credit is meant to reduce the number of cars on the road and limit the sprawl of parking facilities. It also helps encourage carpooling and reduce transportation-related environmental impacts like emissions, stormwater runoff, and the urban heat islandA densely populated area in which pavement and buildings absorb, store, and release solar energy, making the vicinity warmer than it would be if the pavement and buildings were not present. effect.
If you build it, they might come
Before choosing to limit the availability of onsite parking, it’s wise to consider just how likely your building occupants are to take advantage of either nearby public transportation or of the carpooling resources that you may be providing. Choose your approach based on the strategy you believe will have the greatest impact.

Some projects will need to think ahead
If you choose to provide no onsite parking for tenants, this credit requires no preplanning—just document your compliance and submit that documentation. Other projects will want to address this credit early in the lease negotiation process—you’ll need to make sure that the lease documents don’t give you more parking spaces than what is required by code.
Special calculations for Commercial Interiors projects
Your approach to this credit will depend on how much of the building space your project occupies. If your project uses more than 75% of the building area, then you must apply the credit requirements to all building occupants, not just occupants of your tenant area.
FAQs for SSc3.3
Why are the CI designated parking requirements in Cases 1 and & 2 Option 1 determined by a Full Time Equivalent of tenant space/building while for New Construction the requirements are simply a percentage of parking provided?
Since parking availability for CI projects may not correlate with building size or square footage as in the case in NC, this change helps level requirements across CI projects.
If a CI project occupies a building that has existing parking, but no designated parking to the tenant, can it pursue “no parking will be provided"?
Yes. However, if occupants have access, there should be no parking subsidies provided that would encourage tenants to use the parking (as required by credit language).

Pre-Design

You will need to confirm with the building owner that the lease does not guarantee more parking spaces than the number required by code.
Consider this credit, and the reduction of parking capacity, before negotiating your lease. It is helpful to research zoning requirements for any building you are considering leasing.
Ideally, the research of zoning ordinances informs your lease negotiations, so that you can make sure the lease document does not “guarantee” more parking spaces than what your project requires by code. A “guaranteed space” is one that is reserved solely for tenant and tenant guest use, or is a portion of a reserved parking area for tenant use.
The parking spaces that need to be assessed for this credit are only the spaces located within the LEED boundary. If your building’s occupants have access to parking that’s outside the scope of the project and the LEED boundary, you don’t have to factor it into credit calculations.
This is generally a low-cost credit. Reducing built parking capacity can even reduce construction and maintenance costs. The only added cost might be signage for preferred parking spaces, if applicable.

Research local and state tax incentives for carpooling programs. In order to qualify for state or local programs the carpooling program typically must be verifiable and meet specific requirements.
If you’re not careful, limiting parking capacity could be frustrating for occupants, and not behavior-changing. Consider strategies that go above and beyond the credit requirements:
You don't need programs like ride boards for this credit, but if you're going to limit parking, active encouragement of ridesharing can help.Encourage carpooling through educational programs and through reward programs for employees who carpool. Choose a strategy that your population would be receptive to, like reduced parking fees or designated parking spots.- Consider subsidizing mass transit passes, and providing information about public transportation and bike routes.
- If your project is not located near public transportation, consider setting up a shuttle bus to transport employees to the closest commuter hub, providing an incentive for them not to drive. Survey employees to assess interest in such a service. Doing so could also contribute to SSc3.1.
- If you develop a comprehensive transportation management plan that demonstrates a measurable reduction in personal use of cars, you can also earn an Exemplary Performance point through IDc1.
Before implementing any programs to reduce reliance on single occupancy vehicles, assess the likelihood that tenant occupants will actually use them; you may have to provide carpooling incentives to motivate people to share rides, for example. See Resources for more information on rideshares and carpools.
Consider the time that will be spent by administrative or maintenance personnel in administering any programs. Procedures, policies, and enforcement mechanisms may need to be developed.
Choosing a Compliance Path
Determine if your tenant space will be 75% or more of the total building area. This will help guide your compliance path options.
Case 1: Tenant Space Less Than 75% of Total Building Area
Based on which is best for your project, choose one of two options:
- Option 1: Tenant parking spaces must not exceed minimum parking capacity required by local zoning. Also, provide preferred parking for carpools and vanpools that can serve at least 5% of tenant occupants.
- Option 2: Provide no parking or subsidies for parking for tenant occupants.
Locating in a building that has no parking provided or no subsidized parking for the tenant is the most straightforward way to comply with this credit, although it’s not practical for all projects. Assess whether it’s feasible. Is the site close to public transportation? Do most people have to drive to work?
Consider surveying tenant occupants about their interest in a carpooling or vehicle share program, as an additional way to make a reduced parking capacity work.
Case 2: Tenant Space More Than 75% of Total Building Area
Choose one of two options depending on whether your project is new construction or rehabilitation:
- Option 1: For new construction, total parking capacity must not exceed minimum parking required by local zoning. Also, provide preferred parking for carpools and vanpools that can serve at least 5% of total building occupants.
- Option 2: For rehabilitation projects, provide no new parking, and preferred parking for carpools and vanpools that can serve at least 5% of total building occupants.
For rehabilitation projects, adding no new parking is the easiest way to earn this credit. However, you will have to provide preferred parking spaces for carpools and vanpools to 5% of total building occupants in order to earn the credit.
Design Development

The required number of preferred parking spaces for carpool or vanpool spaces is based on the number of full-time equivalent (FTE) occupants—either tenant occupants or building occupants—depending on the amount of space you occupy in the building (decided by choosing Case 1 or Case 2, above).
“Preferred parking” refers to designated spaces located nearest the building entrance (thus “preferable” over other spaces), covered, or at a discount price, but not providing preference over disable parking. Preferred parking spaces must be clearly designated, for example with a sign that states “Carpool and vanpool parking only.”
There are no “LEED Police.” The preferred parking spaces required for non-residential buildings are largely based on the honor system and the integrity of building management and users. Consider incorporating an enforcement mechanism that will ensure carpool parking spaces are not abused. To ensure that preferred parking polices are respected, consider the following strategies:
Use signage in conjunction with parking permits.- Use a sticker program to identify carpool vehicles that have access to preferred parking spaces.
- Clearly communicate to occupants the steps required to acquire a parking permit or sticker from building management.
Minor administrative costs may also be associated with enforcing preferred parking spaces.
If you will be developing a carpooling program, consider making provisions for appropriate drop-off areas, distributing information about ride-sharing or vehicle-sharing, or shuttle services that connect building occupants to mass transit in the area. Think about developing a carpooling policy, defining procedures and eligibility requirements for participating in a carpooling incentive program, creating and distributing tags for vehicle identification, creating communication materials, and creating a rideshare board. Be sure to include any of these facilities or programs in the building design as necessary.
Case 1: Tenant Space Less Than 75% of Total Building Area
Depending on your compliance path option (as chosen earlier):
- Option 1: Check local codes and make sure the parking capacity for the tenant space meets but does not exceed minimum parking requirements and verify that your lease does not guarantee more than the minimum. Identify preferred parking spaces for at least 5% of your tenant occupants.
- Option 2: Verify that no parking is subsidized or provided for your tenant occupants.
To document this credit on LEED Online, a lease containing language verifying your project meets the requirements is ideal. If your lease does not contain this language, you can provide a letter from the owner verifying compliance.
Case 1, Option 1: Minimize Parking
The required number of carpool or vanpool spaces is based on the number of full-time equivalent (FTE) tenant occupants and not total building occupants.
Calculate the tenant occupant FTE, based on an eight-hour occupancy period. An FTE occupant of eight hours has a value of one (8 hours ÷ 8). A part-time occupant, on the other hand, has a fractional value (number of hours ÷ 8). If your tenant space has shifts, calculate the FTE based on the highest volume shift. It follows that:
- Total FTE staff occupants = Total Occupant Hours ÷ 8.
Calculate 5% of the tenant occupant FTE, to determine the number of carpool and vanpool preferred parking spaces will need to be allocated. Assuming that all carpools will have two occupants per vehicle the calculation will be as follows. However, if you know there will be more occupants per vehicles, adjust the calculations to reflect the difference. Consequently, you may not need to provide as many parking spaces but will need to justify the reasoning in a short narrative.
- Total required preferred parking spaces = (FTE X 0.05) ÷ 2.
When calculating for preferred parking spaces, always round up! For example if you have (125 FTE X 0.05) ÷ 2, the math works out to 3.13 spaces—but you will be required to provide four spaces, and not three.
Case 2: Tenant Space More Than 75% of Total Building Area
Depending on your compliance path option (chosen earlier):
- Option 1: Check local codes and make sure your planned parking capacity meets but does not exceed minimum parking requirements. Identify preferred parking spaces for at least 5% of total building occupants.
- Option 2: For rehabilitations, verify that no parking is added and provide preferred parking spaces for at least 5% of total building occupants.
The required number of carpool or vanpool spaces is based on the number of FTE for total building occupants—not just the FTE for tenant spaces.
Calculate the total building occupant FTE, based on an eight-hour occupancy period. An FTE occupant of eight hours has a value of one (8 hours ÷ 8). A part-time occupant, on the other hand, has a fractional value (number of hours ÷ 8). If the building has shifts, calculate the FTE based on the highest volume shift. It follows that:
- Total FTE total building occupants = Total Occupant Hours ÷ 8.
Calculate 5% of the total building occupant FTE, to determine the number of carpool and vanpool preferred parking spaces will need to be allocated. Assuming that all carpools will have two occupants per vehicle the calculation will be as follows. However, if you know there will be more occupants per vehicles, adjust the calculations to reflect the difference. Consequently, you may not need to provide as many parking spaces but will need to justify the reasoning.
- Total required preferred parking spaces = (FTE X 0.05) ÷ 2.
When calculating for preferred parking spaces, don’t forget to round up! For example if you have (125 FTE X 0.05) ÷ 2, you are required to have 3.13 spaces—you will be required to provide 4 spaces and not 3.

Ensure that you meet the minimum parking capacity following your credit option. If applicable, verify that preferred parking spaces are included in your plans and in your total parking count.
If you pursue an option that makes provisions for carpools, design your facility to include transportation amenities for a carpooling program: appropriate drop-off areas, preferred parking for carpools and vanpools, and space to post rideshare program and other relevant information for building or tenant occupants.
Ensure that preferred parking spaces are included in your total parking count and on construction documents.
Mark your parking areas, and any carpool drop-off areas, in the parking layout drawings. Preferred parking spaces must be clearly designated, for example with a sign that states “Carpool and vanpool parking only.”
If your project will be organizing a carpooling program, finalize the program details and infrastructure, including any literature, brochures, newsletters and other materials that inform employees about carpooling and its benefits.

Is the 5% really only based on the FTEs and not the peak building users? If the 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.

(The parking provided serves both the FTEs and the visitors (transients) so it seems like LEED really should be addressing both of these as is done in NC.)
Michelle,
Yes, that is my understanding. LEED-NC assumes the client/owner has a greater influence over the site design and therefore has more opportunity to provide car- /van-pool spaces. For this reason some of the site requirements in LEED-CI are lesser than that of LEED-NC. Further, most LEED-CI tenants I've worked with only negotiate a smaller number of "guaranteed parking spaces," which is based off the number of staff the tenant has, and a larger number of "available parking spaces." The "guaranteed" spaces are specific to the tenant [usually designated as such], the "available" spaces are not.
However, I would also add that if your client realistically expects a hundred daily visitors and they can realistically expect these visitors to carpool, then by all means, encourage them to put in the additional two car- /van-pool spaces. Otherwise ,the one space will met the requirements of this credit.
Preferred parking spaces

The CS building has 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 for electrical vehicles. In order to locate the preferred parking spaces for the carsharing, can we put them next to the parking for the electrical vehicles or would it be required to move the parking spaces for electrical vehicles so that we can have a parking space for a carsharing program? I guess that last option does not make a lot of sense but wanted to check if anyone had any opinion on this
If the spaces for electric vehicles are charging stations, it seems crazy to have to move them, if you can offer 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. right next to them.
If the spaces are just regular spaces designated for electric vehicles, then I would look holistically at the building and thing about what makes sense. Seems unlikely that you would need to move them. Maybe combining them to be preferred for all relevant vechicles, while making sure you have enough for everyone, would make the most sense.
GBCI Review Comments Regarding Parking Requirements for Campus
Our project is a small TI inside a larger building on a campus with other buildings. The project falls under Case 1, Option 1. We submitted documentation demonstrating that the parking spaces provided for our TI space do not exceed the local zoning regulations and we’ve provided the required 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.
Our preliminary review comments stated that we need to “Provide documentation such as a zoning regulations and calculations which confirm that the minimum zoning level has not been exceeded at the campus level.”
Thinking that the review team did not understand that our project falls under Case 1, Option 1, and thus holding us to the requirements of Case 2, Option 1, we emailed the review team for clarification. We received the following response, "the review team recognizes that Option 1 applies to this project. However, the parking spaces for this project are located in a parking lot that serves buildings other than the project building. Under these circumstances, the project team must demonstrate that the overall parking capacity of all of the buildings served by the parking lot does not exceed zoning requirements."
I have searched through LEED Interpretations, Addenda, and of course the LEED ID+C Reference Guide, and I see nothing that supports this requirement. Can anyone shed some light on this before I go back to the review team for further clarification?
I was going to say that the review comment is concerned about gerrymandering, but I don't really see the logic.
Have you received any clarification?
We finally scheduled a conference call with GBCI to clear up this issue since we could find no addenda, interpretations, etc supporting the technical advice. We were able to work things out with them and in the end, we have provided a narrative confirming that the number of parking passes provided to the TI space occupants does not exceed the minimum parking spaces per zoning regulations. We also explained that occupants whom do not have parking passes are discouraged to park in the lot because they have to pay high rates which are not reimbursed. In addition, we explained the parking enforcement system in greater detail. We have submitted our documentation for final review, so we shall see...fingers crossed. I'll be sure to post the final outcome.
Lisa, thanks for the follow up here. Did GBCI ever explain if there was some requirement that they were attempting to enforce, that other projects might want to know about?
I better wait until the final review is over before I speak freely : )
Exemplary Performance Point
Can anyone decribe what is expected by "demonstrate a quantifiable reduction in personal automobile use"? Is this just a plan that describes what options are available and how the occupants can access them, or do I have to complete an Alternative transporation/Commute Survey to demonstrate compliance like LEED EBOMEBOM is an acronym for Existing Buildings: Operations & Maintenance, one of the LEED 2009 rating sytems. 2009 SSc4: Alternative Commuting Transportation?
The plan describing the transit options available does not by itself quantify how many fewer personal cars will be driven - for that we'd need a transit study showing actual reductions, or a traffic engineering study that uses industry-accepted calculations for predicting car usage.
no minimum local zoning regulations
What if there are no minimum local zoning regulations regarding number of parking spaces? In that case, is it enough to provide preferred places for carpools?
Adam, that should be enough, yes.
What if there are no local zoning requirements but tenant has still rented some parking spaces? Will this be considered exceeding minimum zoning requirements?
Lesser parking numbers than local norms
The requriement of the credit - "parking availability" is to meet but not exceed local norms. Hence If a project's parking capacity is lesser than local norms does the project meets the credit requirement? please note the project occupants are using public transporation to commute and thereby the intent of the credit is met
Lavanya, what you describe could be enough to meet the credit requirements, but to be sure, please reference the LEED credit language above.
PUDs
Is parking that is negotiated as part of a Planned Unit Development (PUD) considered the same as a zoning requirement?
Peter, I think that would depend on the specific local regulations. Certainly, if rules governing the PUD are how the zoning regs are being enforced, that would make sense.
Dormitory and Car/Van Pool Parking
We are renovating the interiors of two existing dormitories on a college campus. Per LEED-CI SSc3.3 we fall under Case 2. We are not providing any new parking. The credit requires that we provide at least 5% of the building 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. with preferred Car/Van Pool designated parking spaces. We can supply this by marking off existing spots in a nearby campus lot and designated to be solely to be used by occupants of this dorm. But, I scratch my head at the logic of this requirement. Since the students who will be living in the dorms are walking to their classes, there is no reason for them to need Car/Van pool parking, except at move-in or move-out, or in order to drive together to the movies. For FTE of 437 occupants, I'll need 11 carpool spaces. Would it make more sense to only include the FTE of those who are employees at the dormitories who might drive every day to work at the dorms? Or, perhaps propose an alternative compliance method of some sort?
Andrew, it sounds like your situation is not anticipated by the credit requirements. I think you could either not pursue this credit as one that doesn't make sense for the project, or just designate the 11 spaces (hard to see any harm in it), or propose an alternative compliance path like one you suggest, knowing that it's questionable whether GBCI will approve it.
shuttle service instead of preferred parking space
Our LEED CI project is inside of a LEED CS retrofit. For SS3.3 my client falls under the CASE 1. The scope of LEED CS also includes an addition that works as a big garage (which is not within the scope of LEED CI), once retrofitted building does not provide any parking. We don't know the reason LEED CS project has not applied for SS4.4, once the parking spaces provided (addition) do not exceed the zoning requirements and for that reason our LEED CI client wants to achieve this credit. However, once the CS building has not provided 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 in the garage building, my LEED CI client can't designate this spaces by himself. So, he is providing shuttle service/van pool for more than 5% of his 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. to arrive and leave work, everyday.
My questions are:
1. I am considering to apply for CASE 1-Option 1, although the retrofitted building (LEED CI scope) does not provide any parking for tenants, we still have the garage building (not LEED CI scope). We think the best thing to do is to consider these parking spaces, once tenants will use it and this condition will appear on lease agreement. Is that correct? Or is it possible to apply for Option 2 'No parking is provided'?
2. If I can't designate preferred parking equivalent for my client's FTE is it possible to replace it by providing van pool/shuttle service for more than 5% of occupants and meet the credit requirements?
Karyn, if I understand your question, parking spaces will be provided to tenants, just not within the project boundary. So that is not an option.
I think to provide the shuttle service you would have to get 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 from GBCI to approve this, since it's not one of the CI credit options.
Retail Space inside a Shopping Center
We are looking to certify a retail space inside a huge shopping center under Commercial Interiors (not as Retail Commercial Interior, the shopping is NOT certified) We are considering that our shop (project space) is 100% of the building area undergoing certification. Is this right? So, then are we in Case 2?
Romina, the credit language specifies % of the building area, not the building area undergoing certification. This puts you under Case 1.
Combination low-emitting parking and car pooling spaces possible
In our C&S project the building owner provides 15 parking spaces 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.. The main tenant will rent and use these parking spaces. Additionally we need for Commercial Interior SSc3.3 24 parking spaces for car/van pools. Is it possible to combine the low-emitting and fuel-efficient vehicles and car/van pools spaces? For example: 10 of the parking spaces for low-emitting and fuel-efficient vehicles could be used as car/van pools spaces as well, 5 spaces are just for low-emitting and fuel-efficient vehicles and 14 spaces are just for car/van pools. We have already checked the reference guide LEED CI 2009 as well as the data base for CIRs but we could not find any information concerning this question.
Severin, as long as you are providing a total number of spaces that accounts for all requirements, without double-counting any of the spaces, then you can allow the same parking space to be used for either purpose.
SSc3.3 Alternative Transportation - Parkign Availability
We are working on a project for LEED-CI. It falls under the Case 1, Option 1 but we do not get the 5% 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. closest to the main entrance because the landlord has control over that and we cannot get those spaces.
I have a 2 part question that deals with the note "1" at the bottom of the page, more specifically the discounted parking passes. We wanted to know if there is a minimum the discount needs to be and is there a length of time these need to be in effect? 2nd, if our clients are trying achieve this credit because of this, and they do not initially have enough interest in car/vanpooling, can they achieve this credit if they have a plan in place to implement once they DO have enough interest.
I can only answer your first question. The discount should be in effect indefinately. The discount must be a minium of 20%.
Ashley, if you clearly offer the program, and no one takes you up on it, there's nothing you can do about that. However, I don't think it would be sufficient to conditionally offer the program, i.e. "hey, is anyone interested in this... if so we'll offer a program." Rather you would have to say that the program is available.

Part-time or overtime occupants have FTE values based on their hours per day divided by 8 (or hours per week divided by 40).

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.. In NC SSc4.4 parking spaces should be reserved for 5 % of number of parking spaces. Is either one of them incorrect or is it supposed to be different? One based on FTE and the other on number of parking spaces?
Second question: In Sweden a carpool is like a self-service rental car. You are a member of a carpooling company and you book a car and pay a reasonable fee to use it. Would this qualify? Having a carpooling company in our garage? I think it would be used by both occupants and others! I have understood that the meaning of a car/vanpool in the US and the Reference Guide refer to ridesharing in own vehicles, is that right? That would definitely not be as easy to use for our building occupants.
Maria,
1st Q: It is seems confusing at first, but don't think it is a mistake…
For NC # of parking spaces and size of parking facility is in the building’s control and designed with 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. +visitors/transients in mind. For CI the project might not have control over all parking spaces, or even how many they are designated.
I would guess this change helps requirements across CI projects be more accurate by relating spaces directly to ‘people count’ (so that the Parking availability decisions are based on # of FTE, not how many parking spots the Building may decide to give the CI space).
In my head at least this somewhat justifies the change in Option-1 Case 1 & 2: 5% tenant occupants vs 5% building occupants….
2nd: If you take LEED’s literal definition of carpool in the manual as “an arrangement by which 2 or more people share a vehicle for transportation” your carpooling company may fit the bill? There was a discussion on opting for a US car-share system (ZipCar) in lieu of standard carpools here (http://www.leeduser.com/credit/NC-2009/SSc4.4#comment-13748) for NC that may be useful. Seems like it may be worth the try/exploring more… others have ideas?
Regarding question 1:
Does anyone know an exception to the 5% of the 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. for preferred carpooling parking (LEED CI) when the project is in an urban environment and the preferred spaces number comes to more than the available parking spaces allocated to the LEED CI project? The LEED CS project is meeting SSc4.4 by not exceeding minimum zoning requirements.
Should we submit 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?
Kate,
In line with the previous comments from Susan, I am assessing a project where the tenant is occupying the total of the building. Although there is enough area to add new car park, the client has decided not to do it to encourage the use of more sustainable transport such as public transport of bikes (cyclist provisions are being incorporated). Additionally, the non-addition of car park spaces is in line with Case 2 – Option 1 of the credit requirements. If the number 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. is based on the 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. instead of the number of car parks, then effectively we would need to add car park spaces since a 5% of the FTE is higher than the total of car park spaces provided.
Allocating additional car park spaces, even when it is for carpools, will actually increase the number of car based travel in an area with excellent public transport. Would it be worth it for me to send 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 with this regard?
Many thanks in advance for your help.

Alicia
In response to Susan, LEED CI allows for each carpool space to accommodate 2 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.. Knowing this, are you still under the required percentage? Also, you can use Option 2 which allows you to take 5% of the allocated parking capacity. It seems that this would be the easier option for you.
LEED CI - S.S. credit 3.3 - Case 1 - Option 2
Our project area is less than 75% of the total building area - as we are one of the tenants in 25 floor building. So i guess the project would qualify under Case1 - Option 2. Can you someone please let me know what supporting documentation we have to provide to confirm - No parking has been provided for 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.. Also which option do we check on the LEED form? Is it special circumstances or alternative compliance method?
Sheela, when you enter your percentag eon the LEED Online form, a set of checkboxes, etc., will open up that should be fairly self-explanatory.
Confirmation of Case 1 Option 2 and Documentation
To qualify for the 2 credit point here, we would only need to prove that there has been no parking provided or subsidized parking provided to our client (tenant)? For clarity, not tenants of the Total building.
To prove this fact, would you provide a copy of the complete lease agreement to confirm that such a clause does not exist? Or would it be easier to request a letter from the landlord confirming this fact? What have you used as documentation to earn this credit(s)?
Thanks.
And another clarification request, regarding the word "provided", does this refer to a) parking spots 'provided' to the tenant for their use for no charge in addition to the lease agreement, or b) the literal meaning, that no parking spots are 'provided' / available to our client in any manner, whether for additional charge or not (or in other words, the building does not even have a parking lot)?
In our client's case, there is a parking lot located within the building but it is available to them at the same charge per hour as it is to anyone. Anyone, such as a tenant, guests/customers of tenants, or local area users can park for $x/hour. And the lease agreement signed by our client does not include any free parking passes, designated parking spots, or discounted/subsidized parking.
Would this be sufficient to earn the credits under Case 1 Option 2?
I have the same question. The project is about 28% of the total building sf. There will be no new parking provided and no existing parking allotted to the new space. However, the landlord is the tenant's spouse, and no lease exists. However, on leedonline I can note that there will be no parking provided for the tenant AND that no lease exists, but that does not satisfy the credit. I can get a document signed by both parties saying that there is no parking being provided for the new space but will that be sufficient? Should I then document it under alternative compliance?
Raymond, that is for the tenant, not for all tenants.
Jessica, I think a letter would suffice.
Retail - commercial interiors
There is existing parking but no DESIGNATED parking will be provided for Tenant employees.
Can we pursue Case 1 LESS THAN 75% OF BUILDING AREA, path # 2 No parking will be provided or subsidized for tenant employees?
I have this same question. We are renovating roughly 20% of a current warehouse into office space. There is an existing parking lot for the building, but no new parking will be provided. Does this qualify as Case 1 option 2?
I believe both of you would attempt the credit using Case 1 Option 2. If there is existing parking but nothing is being added because of your project, then it would be considered no new parking. As long as there are no subsidies for the tenants, you should be fine.
Electric Vehicle Charging Stations
This project has 224 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.. We've provided 6 carpool spots and are installing 2 Electric Vehicle Charging Stations that services 4 dedicated EV parking spots. The client and team wants to look into getting an innovation credit point for installing the EV stations.
Knowing that the exemplary credit here are either for Double Transit Ridership (which we don't have), is it appropriate to attempt this EV innovation credit under Comprehensive Transportation Management Plan or is this better suited under the the Innovations in Design section?
Susan, I think you should include this approach as part of a comprehensive plan for EP. I don't think that pursuing it as an innovative approach would work.
LEED CI parking for company vehicles
The project would like to look into Case 1 option 1. The tenant included carparking spaces into the lease. However, all the parking will be occupied by company vehicles which will only travel the management by company drivers. If the no. of parking space could meet the zoning requirement and the parking spaces could be located in a good location as priority parking. Could it counted as carpools / vanpools as there is a minimum of 2 person in the car at a time (management + driver)? Thanks!
I don't think a car with a dedicated driver would count as a carpool if there is just the one manager as the passenger. The intent of the credit is to reduce the number of cars used to transport workers to and from the office, but in your situation it doesn't sound like that will necessarily happen. A carpool allows multiple employees to share a car instead of having one car per office worker, so if a company vehicle and it's driver regularly bring more than one manager to work or back home it might count as a carpool, but if each car is assigned to a single manager it doesn't sound like that would qualify as a carpool.
No local zonal regulation
The project planned to have active vanpooling commuting, parking is provided by the LL, 5% of 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. dedicated for that purposes as per credit requirement. However research & enquiries indicated in this China small city, the local municipality do not have any parking zoning regulation whatsoever, so how to determine the requirement of not exceeding minimum parking zoning?
Are there any other similar cities that do have parking zoning regulations you could reference? If you can show several similar cities and establish what is "typical" for this kind of project, you might be able to convince the reviewers.
Off Site Parking
Can one acheive this credit via compliance path B. (no parking) if the facility has no on-site parking, but does have an off-site parking lot with a shuttle service? They are in reality providing probably more parking than what zoning even requires, but it's far enough away from the facility that perhaps it could be considered similar in function to a park-and-ride?
It doesn't sound likely to be accepted, since there is actually parking provided. Also, the shuttles appear to be just replacing the final leg of each person's commute to the building, so it doesn't appear to reduce the total number of cars that the users will drive in order to get to the facility.
Tenant Infill within a Parking Garage
Our Project is a restaurant taking up less than 75% of a parking garage. We are going for SSc3.3 Case 1 Option 1. Our lease provides us with access to two parking spaces. However, there are no physical spaces assigned, but rather we were given two keys to the parking garage. Once inside the parking garage, all spaces are first come first served.
Rather mark a physical space as "carpool," our plan was to only distribute keys to employees who will be driving with at least 3 passengers. Are we likely to achieve the point if we submit under an Alternate Compliance Path and upload a copy of this parking policy?
We ended up submitting the credit claiming special circumstances rather than the alternate compliance path and we were awarded the credit.
Interior Project inside a complex CS
We have a project inside of one tower that have like common area the parking spaces. However, this tower have a certification LEED and yours parking spaces makes part of complex (AGMBC). The question is wether we can use the predestinated parking spaces for tenant occupants of this tower once that parking spaces serve the tenants or we must too create a demarcation by tenants? Currently the complex has 116 parking spaces separeted for carpools and vanpools. The LEED CI project inside of one tower this complex required 88 parking spaces preferred by your 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.. Is it correct that in order exceed parking spaces preferred serve for the futures tenants that pursue certification LEED?
Paola, I think your question is being lost in translation. Can you please try again to explain it? Please note which case you fall under for this credit.
Minimum number required by local zoning regs
I'm not so savvy with how local zoning regs are worded. I did search for my city's local zoning regs and I'm not sure if what I found is it. Anyway, does this mean that a municipality will say something like "Your high rise building has 10 floors with a max occupancy of 2600 people and so you have to have a parking garage that will hold at least 40% of your max occupancy." In our case, we will be occupying 1/2 of one floor in a high rise and we might be assigned some of our own parking (pending negotiations with owner). How do I determine what our office's min parking is? I'm a little confused by this credit. Can anyone shed some light?
Is there someone in the municipal planning office who could help you? In my experience the relevant information is found in the zoning regs for whatever zone you are in. Something like what you said might be roughly what one might find.
I'm not sure if this is helpful, but I think the answer is to be found in the zoning, and the planning office would be the go-to resource for understanding that.
Hi Patricia,
I agree w. Tristan - contact your local Planning and Development Dept. Some jurisdictions will determine zoning based on a ratio of one required parking space per x number of gross square feet (1:200, or 1:300, etc.) depending on the building type.
THANK YOU Tristan and Edgar. I'm going to do that. Thanks again!
Alternative Transportation Reviewer Comment
First time using this disuccsion thread and looking forward to your input. LEED-CI SSc3.3 Version 2, Technical Advice form the reviewer says "Correct the template calculation utlizing numbers for either the project space or the enitre building for both the numerator and demominator". What is meant by this? The template has the correct Gross Building SF 1,432,607sf and Gross Tenant SF 14,070sf.
Eric,
I'm honestly not sure what the reviewers are asking here. Can you provide more information. I assume you are following Option A? One thought - is the owner and the tenant the same for your project? If so, then the ratio would equal 100% and push you into Option B. Provide me some more info and maybe I can help you more.
Local zoning requires no parking
Our project is an in-patient, substance-abuse treatment center, located in a building which also houses an emergency detox facility. The CI project occupies less than 75% of the building, therefore we are under SSc3.3 Case 1.
The project building is undergoing renovation at the same time as the CI tenant project, and as part of that renovation, the on-site parking is being reduced substantially (from 24 to 11 spaces; of those 11, 2 or 3 will be reserved for the detox facility's 'fleet' vans and police vehicles). However, the project is located in a zone with no minimum parking requirements, so we are in excess of zoning minimums.
Would we have to not exceed the city's 'no required minimum' (i.e. provide zero spaces) in order to comply with Case 1 Option 1?
Does anyone have any experience with alternative compliance paths in a situation like this, perhaps either by referencing the NC 'Option 4' (25% less than ITE study) or arguing that the significant reduction in spaces ought to qualify? (Using the ITE route would be complicated in any case, as neither of the land use types for the two uses are explicitly included in the ITE study.)
Michael,
I think you may fall under the special circumstances choice on the letter template. My thoughts are that you are not adding new parking since these parking spaces existed prior to renovation and to the fact that the number of parking spaces is being reduced. I would think that in your narrative you explain your project and that even though your space is 75% less than the total building area, your project complies with Option 2 of Case 2. I would also reference a CIR ruling for NC SSc4.4 dated 5/23/08. The Ruling states, " In regard to the second question, the reduction in parking numbers as a result of the development of this project can be considered an equivalent approach to Option #4 – No New Parking. The submittal documentation should clearly identify the pre-development and post-development parking scenarios and numbers, demonstrating no net increase in parking as a result of this new project." In your case, it would be equivalent to Option 2 of Case 2. Either way, I think you can clearly argue you are meeting the credit intent. Good luck.
no desigated/assigned/reserved parking for tenant
Our tenant's lease makes no provision for "guaranteed" designated/assiged/reserved parking for the tenant although there is a parking lot provided in general for all tenants in the building: first come, first served.
Our project falls within the Case 1 size, but would option 2 apply in our case? In reading the Implementation section of this credit in the referene guide, it almost seems like it could apply.
Any comments?
I think the "guaranteed" language creates an ambiguity here that might be opposite of the credit intent.
Assume this is a stand-alone office building with it's own parking lot on private property: the number of spaces provided is likely to be addressed by zoning. If the building provides parking, but doesn't guarantee it for any of the tenants, the parking is still "provided" and should be limited in keeping with the credit requirements.
Say a site is zoned for minimum of 100 spaces for a building of this size, but 125 spaces are provided. If the tenant occupies 76% (Case 2) of the building, I would think this credit would not be earned because the parking "capacity" exceeds minimum zoning, whether the spaces are guaranteed or not.
If the tenant occupies 74% of the building (Case 1), it seems the same rules should apply. That's my interpretation, though I'm curious to see how others would view this.
Kathy, sorry for the late reply but regarding your second paragraph, I would assume that your facts (of occupying less than 75% of the building space) would automatically slot you into Case 1 and Case 2 options would not be applicable in your case even if you may qualify under their stipulations. Does anyone disagree or has actually applied differently from my assumption?
Automatic for a LEED CS certified building?
It states above, "Projects located within a LEED-certified building that achieved this credit in another rating system (for example LEED-NC SSc4.4) automatically earn the credit based on existing parking spaces.
We are documenting a space that is in a LEED Core and Shell v.2.0 platinum building that achieved SS credit 4.4. I don't see on the LEED CI credit form that this is an option? How would you go about documenting this?
Sorry, but I am having trouble with the LEED Online CI SSc3.3 form right now. It won't allow me to enter a percentage in the first input, to see how the rest of the form looks.
I would suggest you upload this documentation as an alternative compliance path, and/or check with your reviewer or GBCI.
I'm just looking into this for a project in a LEED-NC v2.2 base building that earned SSc4.3 and SSc4.4. There still appears to be no check-box on the LOv3 form for this credit, and the reference guide does not clearly state this opportunity. Can we confirm this with USGBC/GBCI somehow?
I would contact your reviewer, or GBCI using the feedback form on the site.
Please post back here with what you learn!
