• c. in exposure Zones B, C and D as defined in NZS3604:2011. Microclimatic Conditions (refer NZS3604:2011 paragraph 4.2.4) are outside the scope of this certificate for both timber framed and steel framed buildings, and
• d. up to 10 m in building height, and
• e. further than 1m from a relevant and notional boundary, unless compliance may be established (outside the scope of this certificate) through reliance on C/AS1 or C/AS2.

• c. with a risk score not greater than 20, when evaluated against:
  • i. E2/AS1 3rd edition, amendment 10 date 5 November 2020 risk matrix for timber framed building or
  • ii. NASH building Envelope Solution:2019 risk matrix as referenced by E2/AS4 for steel framed buildings, and
• d. used with aluminium window and door joinery that meets the requirements of NZS 4211:2008 including amendment 1 or has a current Product Certificate or with traditional timber joinery as set out in BRANZ bulletin BU481, and
