3rd edition, amendment 6

All of the Acceptable Solutions and Verification Methods relating to E2 are contained in one document.

• E2/VM1 provides calculations and tests for cladding systems, including junctions with windows, doors and other penetrations.  It provides for pitched, skillion and commercial/industrial roofing.
• E2/AS1, the Acceptable Solution, gives design solutions for roofs, walls and penetrations to the external envelop for low-rise, timber-framed buildings.  E2/AS1 is aligned to the scope of buildings constructed to NZS 3604, the Standard referenced (with modifications) for Building Code clause B1 Structure. E2/AS1 can be used for walls and roofs, and NZS 3604 for structure.  
• E2/AS2 provides a design solution for earth buildings.
• E2/AS3 gives a design solution for concrete and concrete masonry buildings.
