It was primarily an envelope addendum so the ECB changes are pretty far down. The following link (to a pdf download) has many of the addenda to 2010 and the changes are marked:2010 Addenda |

| 2015-04-09 17:08:03 -0500 | answered a question | ASHRAE90.1-2010 - Energy Cost Budget Method - Fenestration Orientation This requirement was changed in 2013. Unfortunately I don't recall the addendum letter that made the change. However, for 2013, the text states that if this condition exists, reduce the total area to the total building percent and rotate the building at 90° intervals to average the exposure (like Appendix G). It may be possible to ask the building official to allow the use of the addendum that affected this text as it is unlikely that the intent of the text in 2010 was to force the baseline building to have 0 glazing in this situation. |
