EVSE and LEED, Two Acronyms That Work Well Together

Wednesday, June 9, 2010
How can installing Electric Vehicle Supply Equipment (EVSE...a.k.a. Charging Station) help a building get LEED certified?

The answer depends on whether you're talking about installing about installing at New Construction or an Existing Building.

EVSE in New Construction
In the 2009 LEED Reference Guide for New Construction, EVSE is addressed in Sustainable Sites Credit 4.3 Option 2.  You can get 3 points for satisfying the requirement is to provide Alternative Fueling Stations for 3% of the parking capacity (or 3 spaces for every 100).  If you would like to see a nice overview of this Credit, checkout this video from www.LEEDForContractors.com.

EVSE in Existing Buildings
In the 2009 LEED Reference Guide for Green Building Operations and Maintenance, EVSE is addressed in Sustainable Sites Credit 4.0.  You can get 3-15 points for satisfying the requirement to reduce the number of commuting trips by your occupants using conventionally powered vehicles by 10-75%.  This requirement requires you to survey your building's occupants to understand how much your actions have reduced commuting trips.  Installing EVSE is one of the incentives the guide suggests to reduce the use of conventionally powered vehicles.

The riddle is: Why have two different requirements?  Seems to me that both of these credits could be used in New AND Existing Buildings.  Anyone got an answer?
