BCA 2012 Abundance 2 - Heap 3.12:<\p>
3.12 - A encore special morpheme 'house energy rating software' has been included for nominate the acceptable accrediting national scheme for software used to size the thermal efficiency of a dwelling envelope.<\p>
3.12 Explanatory Information - New illuminating the picture has been included to explain the purpose touching the NatHERS scheme.<\p>
3.12 - As a consequence of changes to the Australian Government's Renewable Energy Target scheme the defined term 'Renewable Validity Certificate' has been nonattendant and replaced adieu a new defined homonym 'Small-scale Technology Certificate'.<\p>
3.12.0 Illustrative Information - The interpretive information regarding the two options for complying with 3.12.1 to 3.12.4 has been amended to clarify the delineation between the Energy Rating and the Elemental Provisions options.<\p>
