BC Update; No. 79 - New Acceptable Solution for earth buildings

7 March 2008: The Department has published a new Acceptable Solution (E2/AS2) for the weathertightness of earth buildings. It is available for free download from the Department’s website,  and hardcopies may be obtained by calling the Victoria University Bookcentre on 0800 370 370.

E2/AS2 cites New Zealand Standard NZS 4299:1998 Earth buildings not requiring specific design, subject to the following modifications:

  • Revised window and door joinery details
  • Revised foundation and soffit details
  • New information for wall penetrations

E2/AS2 will make the compliance process simpler and reduce compliance costs for earth building and it will benefit designers, builders and building officials.

Acceptable Solution E2/AS2 becomes effective on 1 May 2008.
