CS-2009 SSc4.3: Alternative Transportation—Low-Emitting and Fuel-Efficient Vehicles
I have a client that would like to install charging stations for SS 4.3 Option 2 compliance. How do you demonstrate vehicle fueling capacity per station when each electric vehicle charges at a different rate?

Do all hybrid vehicles automatically qualify for this credit?
How should the signage read for preferred parking spaces?
For electric vehicle charging stations, how are the parameters established for fueling capacity?
I am working on a project with no parking spaces allocated. Can I earn this credit?

Not sure if I understand your question - the credit requirements are only looking at "capacity" as the number of parking spaces, and providing 3% of that number of spaces as ones reserved for fueling or charging alternative fuel vehicles. We don't need to provide info about the rate or capacity of power being provided - except that actual charging equipment does need to be installed (not just 120 V outlets) Does that answer your question?

In LEED v3 the reference guide sais "prepare information about the number of fueling stations provided, the alternative fuel station type, manufacturer, model number, and the fueling capacity per station" (documentation guidance).
In LEED CS v2.0 it sais even more: "confirm the fuel type, number of stations, and fueling capacity for each station for an 8-hour period".
So I guess we need to specify the power of charging equipment. As far as I am concerned, different electric vehicles need different plugs and voltage...
Any idea how detailed the specification needs to be?
Thanks!

Hi, Alicja!
If you install 240 volt charging stations, then the assumption is that you are offering what is considered a "rapid charge," and that an electric car could fully charge in at least 8 hours. As far as documentation goes, you would need to show the number and location of the refueling/recharging stations, as well as the specifications for the type of station being provided (with the intent of proving that you are providing at least 240 volt outlets). Hope that helps!
