Energy Commission Approves Updated Compliance Software
From an email sent by the California Energy Commission on June 30, 2010:

On June 23, the California Energy Commission approved updated versions of
MICROPAS (8.1) and Energy Pro (5.1), the two most popular versions of the
computer simulation programs used to demonstrate compliance with the 2008
Building Energy Efficiency Standards.  At the same time, the CEC also
established July 31, 2010 as the official date for which the older versions of
these two programs become decertified and are no longer allowed for use in
showing compliance with the new energy efficiency standards.  If you have
completed your T-24 energy calculations on older versions of certified T-24
software you must submit those calculations before August 1, 2010.  After July
31, 2010 only the new certified software is approved for use.  Energy
calculations for master plans using previously approved software and submitted
prior to August 1, 2010 are good unless the plans are modified after July 31 and
require new T-24 energy calculations.
