LEED Addenda

April 2010 marks the first release of the quarterly addenda to the LEED 2009 rating systems and reference guides. This formalized process incorporates changes and improvements to LEED 2009 resources; addendum is subject to committee review. 

With the release of each quarter's addenda, each rating system with posted addenda will be updated and published with those revisions; the original and updated rating system documents are provided in the appropriate sections below.  Note the date on the first page of that document. Reference guides and their e-versions will be updated in subsequent reprints. Archived addenda documents can be found here.

NOTE: Addenda documents may be subject to minor editorial revisions after the publish date to correct any publication errors; these do not affect the intent of the addenda items. Please refer to the date in the bottom right corner of the addenda document for the most recent version of the addenda. July 19, 2010, is the most recent quarterly addenda publication, with the exception of LEED for Homes.

There are five sets of addenda:
Green Building Design and Construction
Green Interior Design and Construction
Green Building Operations and Maintenance
Green Neighborhood Development
Homes
