Code Development

Summary

New Zealand has had national mandatory requirements for thermal insulation in new homes since 1978. When the government introduced the performance-based New Zealand Building Code (NZBC) in 1993, these requirements were converted to performance terms for residential buildings, and new requirements were added for commercial buildings (Clause H1).
