Clause G4 of the New Zealand Building Code addresses ventilation. The design and compliance pathway for a particular building depend on its use, consent documents and the requirements agreed with the building consent authority.
Commissioning records can help demonstrate that installed mechanical ventilation performs as specified. Useful records identify each system and terminal, the required and measured flow rates, test conditions, instruments and any outstanding issues.
A commissioning report supports the project’s evidence package. It does not itself issue a Code Compliance Certificate or replace design verification, producer statements or other documents required by the consent authority.
Requirements and referenced documents can change. Check the current MBIE Building Performance guidance and the project-specific consent requirements with the design team before setting the test scope.
Apply it to your project.
Every building has its own requirements. Tell us about your systems and project stage so we can discuss a suitable commissioning scope.
General information only. Verify current requirements with MBIE Building Performance (opens a new tab) and the project’s design team. Green Star and NABERSNZ requirements are set by their respective programmes.
