This pilot credit represents the draft language for a new Green Vehicles credit in LEED v4. The credit requirements represent an evolution of the longstanding 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. credits from earlier versions of LEED. See the credit language for full requirements.

To reduce pollution by promoting alternatives to conventionally fueled automobiles.
* This credit language is drawn from the LEED v4 draft. Where other point totals are noted, this pilot credit is worth 1 point in total. *
Designate 5% of all parking spaces used by the project 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 green vehicles. Clearly identify and enforce for sole use by green vehicles. Distribute preferred parking spaces proportionally among various parking sections (e.g. between short-term and long-term spaces).
Green vehicles must achieve a minimum green score of 45 on the American Council for an Energy Efficient Economy (ACEEE) annual vehicle rating guide (or local equivalent for projects outside the U.S.).
A discounted parking rate of at least 20% for green vehicles is an acceptable substitute for preferred parking spaces. The discounted rate must be publicly posted at the entrance of the parking area and permanently available to every qualifying vehicle.
In addition to preferred parking for green vehicles, meet one of the following two options for alternative-fuel fueling stations:
Install electrical vehicle supply equipment (EVSE) in 2% of all parking spaces used by the project. Clearly identify and reserve these spaces for the sole use by plug-in electric vehicles. . Parking spaces that include EVSE must be provided separate from and in addition to preferred parking spaces for green vehicles.
The EVSE must:
Install liquid or gas alternative fuel fueling facilities or a battery switching station capable of refueling a number of vehicles per day equal to at least 2% of all parking spaces.
For New Construction projects self-identifying as warehouses only:
Provide an on-site fleet with at least one yard tractor that is powered by electricity, propane, or natural gas. Provide on-site charging or refueling stations for the vehicles. Liquid or gas refueling stations must be separately ventilated or located outdoors.
Provide an electrical connection for at least 50% of all dock door locations to limit truck idling at the dock.
Register for the pilot credit
For this credit achievement, there has been project team discussion about details required. Company only uses electric vehicles on campus. How much information on vehicles, policy, purchasing, etc. is necessary.
Hi Kath - Hopefully I've understood your question correctly. It sounds like you are wondering how to comply with the credit with an electric vehicle fleet, and what documentation will be asked of project teams.
It is important to note that there is currently no compliance path for electric company vehicles. Rather, the credit rewards teams that install chargers proportional to the total parking capacity for all vehicles. Vehicle fleet performance is only addressed in Option 2 of the Schools credit.
In general, documentation for this part of the credit must show that a sufficient number of vehicle chargers have been provided for the building (at least 2% of total parking capacity), that the parking spaces associated with the chargers have been reserved for electric vehicles, and that manufacturer documentation for the charger demonstrates the following: Level 2 or above charging capability, compliance with SAE J1772 or another relevant standard, and internet addressability.

I would like to know what LEED understands with off-peak charging.
Is it trying to help charge electric vehicles off-peak, when they won’t bring down the power grid? Or does it mean to charge during special, off-peak rates and program their vehicles or chargers to use electricity only when costs are low?
Hi Amra (and Yoyo below) - This requirement speaks to the charger's ability to integrate into smart utility grid. This requires a network connection. In operation this will typically involve participation in peak demand or time-of-use pricing, which is an arrangement in which customers pay higher fees to use utilities during peak time periods and lower fees during off-peak time periods. The intent is not for the charger to be turned off during any particular period.
Just to add to this, it may be helpful to review the language in the Demand Response credit to understand the intent of "off-peak charging" in this credit. So the main intent of off-peak in Demand Response is to reduce capacity needs on the part of the utility. Costs savings might be an additional benefit to some projects, but this will vary from project to project and from utility to utility. Therefore, off-peak should focus on capacity, rather than pricing.
As in the requirement, EVSE must be networked and internet addressable and be capable to encourage off-peak charging.
However, the team proposed to physical locked the charger by property management and the charger will be unlocked if there is a demand. If the charging is performed during off-peak, a discount will be provided. Does the approach meet the requirement mentioned above?
Can a project pursue LTpc70 as an Innovation in Design Credit if SSc4.3 has been awarded? In addition to the dedicated LEFE vehicle parking, the project also includes a CNG fueling station and electrical connections at more than 50% of the dock doors.
Thanks for your question, Kenner. Yes, this is an acceptable approach since the two credits differ in their requirements. Feedback on your project’s implementation of these differences is helpful for USGBC staff. If the LEED project self-identifies as a warehouse or distribution center, Option 2. Reduced Truck Idling in PC70 can indeed be pursued in addition to Option 2 of SSc4.3 in LEED 2009 for the CNG station (or any other SSc4.3 option for that matter, provided requirements are met). However, note that non-warehouse space types must pursue standard requirements for 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. and alternative fuel stations (for instance, a restaurant with a loading dock door is ineligible).
Hi, we are trying to achieve this pilot credit, and we doubt if the prefered spaces already reserved for credit SS4.3 for low emitting and fuel efficient vehicles could be counted also for the compliance of this pilot credit.
Hi Albert - Thanks for your question. As you can tell, the credit requirements for SSc4.3 in LEED 2009 and for PC70 differ in a few key ways, most notably that both 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. and alternative fueling stations are required. For preferred parking spaces, the definition of qualifying vehicles has also changed from an ACEEE Green Book score of 40+ or recognition as CARBThe California Air Resources Board, part of the state government, is charged with maintaining clean air. This agency is unique at the state level: California was the only state that had such an agency before the passage of the federal Clean Air Act, and was allowed to keep it. ZEVZero-emission vehicles. in LEED 2009, to an ACEEE Green Book score of 45+ (only) in PC70.
These differences are substantial enough so that both SSc4.3 and an ID credit for PC70 can be pursued in the same project. To do so, signage for preferred parking may refer to either “low-emitting and fuel efficient vehicles” or “green vehicles”, but the stricter ACEEE Green Book score of 45+ specified in PC70 must be used and enforced for all designated spaces.
(For the alternative fuel station requirement, note that additional specifications for EVSE must be met if the project has chosen this alternative fuel type – namely, Level 2 or greater charging speed, compliance with SAE J1772 or IEC 62196, and IP addressability. As with ACEEE the stricter of the two percentages of total parking capacity between the two versions must be met, which is 3% in LEED 2009.)
Im not sure if in this pilot credit applies that the parking facility is not part of the LEED project construction scope. We are aiming to obtain the credit SSc4.3 with the parking facility of the building besides our site. These parking spots are for electrical cars and already have the electrical car chargers. Would it be possible to apply for this pilot credit with all this info?
Thanks a lot!
Hi Maria - The pilot credit would use the same qualification requirements as SSc4.3, so if you are receiving credit under SSc4.3, you could probably qualify for the pilot credit as well. In terms of receiving credit for parking outside of the LEED project scope, if you are pooling parking with the other building, the point would probably be awarded as long as the project uses reserved spaces for the project as the project’s parking capacity OR uses the entire parking garage as the capacity if spaces are not reserved.
