Historic Documents

Before launching the current version of STARS, AASHE released several prior versions as well as earlier drafts for public comment and piloting. Key documents from throughout the STARS development process are posted below.

STARS 2.x

AASHE launched the STARS 2.0 Technical Manual (early release version) in August 2013. AASHE made minor administrative updates that were incorporated into the version of the Technical Manual (Administrative Update One) that accompanied the launch of STARS 2.0 in October 2013.

The current version of STARS 2.0 - Administrative Update Two was published in January 2014 and includes minor revisions and modifications.

STARS 1.x

AASHE launched the STARS 1.0 Early Release Technical Manual in September 2009 that included all of the credits but limited supporting information as a sneak peek to those interested in participating. AASHE made minor administrative updates after releasing this document that were incorporated in STARS 1.0 that launched in January 2010.

AASHE incorporated additional support information in the Technical Manual after the early release and launched the completed STARS 1.0 Technical Manual, website, and Reporting Tool in January 2010. AASHE issued an Administrative Update to this version in June 2010 and November 2011.

AASHE launched STARS 1.1 Administrative Update One in February 2011. This Administrative Update contains basic system maintenance changes to STARS 1.1, such as additional language to clarify credits and correction of typographical errors.

AASHE released STARS 1.2 in February 2012.  Like the changes from STARS 1.0 to STARS 1.1, this version of STARS includes minor updates to the system.

Learn how credits were organized and weighed in each of the STARS 1.x versions of the Technical Manual.
