Acceptable Solution E2/AS2 provides a means of compliance with New Zealand Building Code Clause E2 External Moisture for Earth Buildings.
Building Code Clause E2 ensures external roof, wall claddings and external openings will prevent external moisture from causing undue dampness or damage.
It requires buildings to be constructed to provide adequate resistance to penetration by, and the accumulation of, moisture from the outside.
It contains requirements for roofs, wall claddings and external openings to:
prevent water entry
prevent water absorption and transmission
prevent the accumulation of water
allow for dissipation.
The clause applies to most buildings, as set out in the limit on application in E2.2.
Earth buildings complying with NZS 4299 as modified by this Acceptable Solution meet the performance criteria of NZBC E2.
Scope
Where buildings are based on NZS 4299 but require specific structural engineering design input, the structure must be of at least equivalent stiffness to the provisions of NZS 4299. Such designs are outside the scope of this Acceptable Solution and proposals must be submitted to, and approved by, the building consent authority as part of the normal building consent process.
