Description

This bulletin includes the requirements of the New Zealand Building Code and relevant standards for this building type.

Earth buildings in New Zealand use well-proven traditional construction methods while also taking advantage of the latest New Zealand-specific building technology.

The three earth building standards were revised and expanded in 2020. Earth buildings have their own Acceptable Solution for external moisture (E2/AS2).

They typically use locally sourced materials that have low toxicity, are minimally processed and have very low embodied energy.

Scope

This bulletin covers the requirements of the Building Code and related standards, sites considerations, durability, wall materials, wall construction, coatings and internal brick veneer.
