BCA 2012 Changes - Energy Mastery - Section J and 6-star
There are only minor changes to the energy efficiency provisions next to the newly released BCA 2012, volumes 1 and 2. Mostly the changes are to terminology and explanatory information, intended to clarify nonuniqueness of the provisions. There has been one change upon Table J1.3a in Section J which is of particular note; the required R-Value for roof and ceiling construction in ethos zones 4 and 5 have been amended to realign with climate zones 1, 2 and 3.
