NC-v4 LTc7: Reduced parking footprint

  • Encourage alternative transit by reducing parking

    For all projects, parking capacity cannot exceed minimum local code compliance. If new or existing parking is provided in your project, at least 5% of the spaces must be reserved as 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 employee parking, it refers to the spots that are closest to the entrance used by employees. for carpools. Additionally, your total parking capacity must be a percentage reduction below the base ratios recommended by the Parking Consultants Council.

    This credit has different requirements depending on the other LT credits the project is able to achieve. If points are achieved for Surrounding Density and Diverse Uses or Access to Quality Transit, the amount of parking must be reduced to 40% below the base ratios.

    If your project is not pursuing either of those credits, you only have to reduce the amount of parking to 20% below the base ratios.

    Strategies to reduce the number of parking spaces needed for your project include:

    • Providing transit subsidies for building users
    • Allowing telecommuting
    • Allowing a compressed workweekA compressed workweek rearranges the standard workweek (5 consecutive 8-hour days in a week), increasing the daily hours and decreasing the number of days in the work cycle. For example, instead of working 8-hour days Monday through Friday, employees work 10-hour days for 4 days per week, or 9-hour days for 9 of 10 consecutive days. schedule
    • Providing a shuttle service between transit stops and the project building
    • Selling or renting residential units separately from parking

    What’s New in LEED v4

    • There are now consistent requirements for nonresidential and residential projects, and for both New Construction and Core and Shell.
    • USGBC added a baseline reference to the third-party standard, ITE Transportation Planning Handbook, 3rd edition, Tables 18-2 through 18-4.
    • Points are no longer awarded for providing no new off-street parking. Existing parking used by the project must also adhere to credit requirements.

    FAQs

    Can this credit be achieved if the project has no existing parking and is providing no new parking?

    No, this credit does not award points for providing no new parking. If there is existing parking associated with the project, it must comply with the requirements of the credit and show a percentage reduction below the base ratio.

  • LT Credit 7: Reduced parking footprint

    Intent

    To minimize the environmental harms associated with parking facilities, including automobile dependence, land consumption, and rainwater runoff.

    Requirements

    Do not exceed the minimum local code requirements for parking capacity.

    Provide parking capacity that is a percentage reduction below the base ratios recommended by the Parking Consultants Council, as shown in the Institute of Transportation Engineers’ Transportation Planning Handbook, 3rd edition, Tables 18-2 through 18-4.

    Case 1. Baseline location

    Projects that have not earned points under LT Credit Surrounding Density and Diverse Uses or LT Credit Access to Quality Transit must achieve a 20% reduction from the base ratios.

    Case 2. Dense and/or transit-served location

    Projects earning 1 or more points under either LT Credit Surrounding Density and Diverse Uses or LT Credit Access to Quality Transit must achieve a 40% reduction from the base ratios.

    For all projects

    The credit calculations must include all existing and new off-street parking spaces that are leased or owned by the project, including parking that is outside the project boundary but is used by the project. On-street parking in public rights-of-way is excluded from these calculations.

    For projects that use pooled parking, calculate compliance using the project’s share of the pooled parking.

    Provide preferred parkingPreferred parking, available to particular users, includes designated spaces close to the building (aside from designated handicapped spots), designated covered spaces, discounted parking passes, and guaranteed passes in a lottery system. For employee parking, it refers to the spots that are closest to the entrance used by employees. for carpools for 5% of the total parking spaces after reductions are made from the base ratios. Preferred parking is not required if no off-street parking is provided.

    Mixed-use projects should determine the percentage reduction by first aggregating the parking amount of each use (as specified by the base ratios) and then determining the percentage reduction from the aggregated parking amount..

    Do not count parking spaces for fleet and inventory vehicles unless these vehicles are regularly used by employees for commuting as well as business purposes.

    SITES-LEED Equivalency

    This LEED credit (or a component of this credit) has been established as equivalent to a SITES v2 credit or component. For more information on using the equivalency as a substitution in your LEED or SITES project, see this article and guidance document.

Reduced parking footprint for College/University

Project Location: United States

The project is a single building which is part of a larger educational campus. There is no parking designed for this building but staff and faculty will be using a parking garage 0.5 mile away from building inside the campus.
To calculate the base ratio, should I use whole campus' occupancy or just this building's?
Also, the ITE guidebook reference table inside the LEED v4 reference book shows different number than ITE guidebook. Which table to use for base ratio calculations?

Motorcycle Parking Under Cover

Project Location: United States

Can you please help to clarify? What if the motorcycle parking is under cover of a shade structure? Would it need to be included in the parking count for the facility?

I only ask because there is contradictory guidance in the step-by-step guidance section of the Heat Island Reduction Credit. In the Sustainable Sites category on page 201 of the Reference Guide, it states for Parking under Cover, you do need to include motorcycle parking as vehicle parking spaces.

Would this requirement also apply to the Reduced Parking FootprintParking footprint refers to the area of the project site occupied by the parking areas and structures. credit? Or, would you only count the number of motorcycle spaces for the Heat Island Reduction Credit if they are under cover and not count them at all for the Reduced Parking Footprint Credit?

Thanks in advance for helping to shed some light on this issue.

Connected underground car parks

Project Location: Germany

Dear all. We are working on a LEED v4 NC campus project in which two (office) buildings pursuing a LEED certification. In the course of constructing the buildings will provided with two underground car parks which are connected with each other. The car parks are intended exclusively for these new buildings and not for any other building on the campus. Question: Is it possible to calculate one combined baseline parking capacity for the two buildings and compare that number with the total parking capacity of the two connected car parks (instead of the calculation for each individual building)? Many thanks in advance.

"The credit is no longer awarded for providing no new parking. If there is existing parking that will continue to be used by the project, it must also comply with credit requirements."

That would suggest a 100% reduction wouldn't even earn the credit, although providing parking but reducing the capacity from 40%, 60%, or up to 99% of the baseline earns the credit and an EP point.

Does that mean that in some projects you could add one parking space and earn the credit plus exemplary performance but adding no spaces at all earns nothing? Seems odd... would be good to clarify this.

Carpool Requirement

Hi There,

We're working on a high rise condo in Manhattan that is providing very limited parking (18 spaces for 330 residents). We've been tossing around the idea of providing a ZipCar but in reviewing this credit more thoroughly, the reference guide doesn't list car-share services as an option any longer. In my mind providing an actual car to carpool with is much better than just providing a space.

Within the "Related Credit Tips" section, the reference guide states that you can aggregate 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. For employee parking, it refers to the spots that are closest to the entrance used by employees. for carpool and green vehicles, as long as the total supply meets the thresholds for each credit. If we provided an LE/FE ZipCar, do you think this would work as an alternative compliance pathway?

Thanks much!

Marilyn Specht Sustainability Consultant, Integral Group May 23 2016 LEEDuser Expert 849 Thumbs Up

It seems reasonable to me as long as you can guarantee the zip cars would be green vehicles or only be used for carpools (perhaps a building policy or something). Given your project's location, it seems like there could be a potential of alternative compliance as most people do not have cars in Manhattan. I would provide a narrative with your documentation explaining the situation and demonstrating that your case would still meet the intent of the credit. Or you can reach out to GBCIThe Green Building Certification Institute (GBCI) manages Leadership in Energy and Environmental Design (LEED) building certification and professional accreditation processes. It was established in 2008 with support from the U.S. Green Building Council (USGBC). directly if you want a more definitive answer before your submittal.

confused (minimum code requirement & maximum allowable parking)

Hi everyone, I am new to LEED and currently studying it.

in the reference guide v4. LT Credit reduced parking footprintParking footprint refers to the area of the project site occupied by the parking areas and structures.
Step 1. Determine local code requirements
Identify the minimum amount of parking required by local code. Confirm that the project’s maximum allowable parking is less than or equal to minimum code requirements.
--------------------
if the maximum parking should be less or equal to the minimum code requirement, then reduce it by 20% is not an offense to the local code? Is there something I misunderstood?

Alan Scott Director, YR&G Mar 17 2016 LEEDuser Member 43 Thumbs Up

Hi Chris,
Good question.
The requirements can be a little confusing on first read. There are two parts to the requirement. The first is to not exceed the local minimum zoning requirements, if any, for parking. The second is the demonstrate a percentage reduction below the baseline parking demand that is determined for the project using the Transportation Engineers’ Transportation Planning Handbook. That baseline is likely to be higher than the local zoning minimum. If the percentage reduction required for the credit is higher than the minimum zoning, than providing no more than the minimum will meet the credit requirement. If the percentage reduction is lower than the zoning minimum, then the project will have to apply for a variance with the local authority in order to earn the credit, and can use the same parking demand reduction strategies documented for the credit as justification for the appeal.

Hi Kimberly,
I wasn't very specific, was I?
As I understood, the first step is to calculate the max. allowable number of new parking spaces according to the base rate calculation in table 1.
For an office building with max. 100,000 ft2 (9 300 m2): 3.4/1,000 ft2 (3.67/100 m2). The qestion is which area of the building is used for this calculation, gross floor or usable area?
In Germany for example we use the usable office area (tecnical rooms and stairs don't need parking).
We want to acheive this credit for a campus with central parking facilities. So another question is, if the calculation rate for each individual building (=higer base rate) or all the campus buildings togehter (=lower base rate) should be used.

Hi Mark,
The reference guide does not make this clear, however, we have been assuming LEED expects us to use the 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.

( 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.) value rather than the usable floor area for the parking calculations. If you wanted, I assume LEED would be okay with a project using usable floor area if they wished, because this would yield a greater reduction in parking. However, for some space types, simply using the usable floor area, would provide an unreasonably small number of parking spaces for the building.
To answer your second question, if you are pursuing this credit for a campus, you must calculate the base ratio of parking for each individual building type on the campus and then combine the data to determine the total number of allowable parking spaces.
Does that make sense? Let me know if that doesn't seem clear!
Thanks

College/University Campuses

Project Location: United States

For college/university campuses, most new buildings do not include the construction of new parking or if they do it might be a minimum number of service space for facilities staff and deliveries. To demonstrate a project's compliance that provides no new parking, must a project team analyze the entire parking capacity of a college/university campus to illustrate that a parking reduction is achieved below the baseline?

Anne, this credit is no longer awarded for providing no new parking. If there is existing parking, it must comply with the requirements of the credit and show a percentage reduction below the baseline. In the case of a new building within a campus, the number of spaces really depends on the LEED project boundary and where it is drawn. All parking spaces (existing and new) within the LEED boundary need to be included in the calculation for this credit.

Understood that the credit is no longer awarded for adding no new parking, but I'm afraid I still don't understand what to do in the case of a college campus. If a college campus is not defined as a LEED campus, just a college campus, then to demonstrate compliance, must the parking calculations be completed at the scale of the entire college campus? Most colleges don't assign particular spaces to particular buildings, in most instances there differences between student/faculty/visitor lots, but that's it.

In this case since there are no dedicated spaces for the building, you will need to include all the parking spaces within the campus for the calculations and demonstrate a percent reduction from the baseline.

I don't have a copy of this to hand but need to know the content of Tables 18-2 to 18-4. Am I required to purchase a copy of this book in order to determine the appropriate base ratios, or are the tables available elsewhere?

Hi Susannah,
I believe you will need to purchase the handbook, I have not seen this information available elsewhere.

Thanks Kimberly.

Wondering if anyone is able to provide me with details of what is required as per the "Transportation Planning Handbook Table 18-2 to 18-4"? We are undertaking a pre-assessment for a project with a view to deciding whether to pursue LEED certification so I would rather not have to buy the handbook at this early stage just to determine whether we are likely to achieve this credit.

Many thanks.

Hi Susannah,
Actually you can find the content of Tables 18-2 to 18-4 on pages 115 to 117 of the LEED v4 reference guide.

I compared the ITE tables 18-2 and 14-2 to the base ratio tables in the reference guide but the parking requirements are different! Which one is the correct one to use? Thanks

Leased off-street parking spaces

Project Location: Mexico

Hi!
We are working on a project that does not provide any off-street parking on site but parking spaces for employees are leased from 3 nearby parking garages. The parking spaces are not assigned, valet parking service is provided.

Can the credit be obtained if the number of parking spaces leased by contract do not exceed minimum local code requirements for parking capacity plus a 40% reduction from the base ratios is achieved (Case 2)?
Would 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 employee parking, it refers to the spots that are closest to the entrance used by employees. have to be provided?

Thank you!

I would venture that this is achievable, provided that 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. For employee parking, it refers to the spots that are closest to the entrance used by employees. is provided for either the entire parking structure OR 5% of the project leased spaces are preferred with signage reserving the spaces for ONLY the LEED project occupants.

Motorcycle parking spaces

Project Location: France

When determining the actual parking capacity of the project, do the small motorcycle parking spaces count ?
Since motorcycles do not allow carpool, it would seem coherent to exclude motorcycle parking spaces from this credit's calculations.

Hi Catherine,

Good question. For LEED v4, project teams are currently instructed to exclude "motorbike or bicycle spaces" from total parking capacity at the discretion of the project team. This means that motorcycle stalls will not count towards or against credit requirements.

This is detailed in "LT Overview, Total Parking Capacity" of the Getting Started section of the BD&C Reference Guide (available here: http://www.usgbc.org/guide/bdc).

Hi Christopher,
Thank you for your reply!
I had asked the same question to GBCIThe Green Building Certification Institute (GBCI) manages Leadership in Energy and Environmental Design (LEED) building certification and professional accreditation processes. It was established in 2008 with support from the U.S. Green Building Council (USGBC)., their answer arrived yesterday: "You are correct to assume that motorcycle parking does not need to be included in the parking capacity count for this credit."

Hi Christopher,

Can you please help to clarify? What if the motorcycle parking is under cover of a shade structure? Would it need to be included in the parking count for the facility?

I only ask because there is contradictory guidance in the step-by-step guidance section of the Heat Island Reduction Credit. In the Sustainable Sites category on page 201 of the Reference Guide, it states for Parking under Cover, you do need to include motorcycle parking as vehicle parking spaces.

Would this requirement also apply to the Reduced Parking FootprintParking footprint refers to the area of the project site occupied by the parking areas and structures. credit? Or, would you only count the number of motorcycle spaces for the Heat Island Reduction Credit if they are under cover and not count them at all for the Reduced Parking Footprint Credit?

Thanks in advance for helping to shed some light on this issue.

no parking

If the project does not provide any parking, can the credit be obtained?

Yes, although it's not as obvious as in the 2009 version where Option 3 in the credit form was "no new parking."

In the version 4 step-by-step guidance in the LEED Credit Library it says "Projects with no associated off-street parking automatically achieve credit compliance; no calculations or 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 employee parking, it refers to the spots that are closest to the entrance used by employees. spaces are required."
See http://www.usgbc.org/node/2613971?view=guide

You might want to make a note in the Special Circumstances narrative on the credit form to make sure this doesn't get missed.

Does anyone know whether this approach of having no parking at all, awards 1 or 2 points?

I think "achieve credit compliance" means 1 point since that's what the base credit is worth.

How do you define "no associated" off-street parking? I have a school residence project with no parking within the LEED boundary. Would it qualify to achieve the credit if there is campus parking? Both residence students and non-residence students must apply for parking passes. Since there is only limited amount of parking, residence and non-residence parking passes are not guaranteed.
