Description

On 29 November 2021 MBIE released one of the biggest energy efficiency updates to the Building Code in more than a decade.

On 1 May 2023 we will reach the next milestone in the staged transition.

From 1 May 2023 new building work in homes must meet the new wall, floor, and roof insulation performance requirements.

The changes included an increase to the number of climate zones from three to six, and increased insulation requirements for roofs, walls, floors, windows, doors and skylights. They also provided a new compliance pathway for heating, ventilating and air conditioning (HVAC) systems in commercial buildings. These changes aim to deliver warmer, drier and healthier buildings that cost significantly less to heat, and generate carbon savings through improved energy efficiency.

Scope

This update includes:

• Complying with the new requirements – new buildings
• Altering an existing building
• Don’t miss opportunities to improve building performance
