📢A new ‘Embodied carbon handbook’, developed in collaboration with NABERS, is now available.

There are currently no embodied carbon requirements in the NCC. The handbook is voluntary guidance and is not required for NCC compliance.

It provides information for practitioners who choose to consider embodied carbon outcomes in their projects.

🔍 We've noticed that stairs is a top search topic among our website visitors! To help you out, we have highlighted some key areas of the NCC and the Housing Provisions that relate to this topic.

Various requirements about stairs are found throughout Section D of NCC Volume One, including:

• when a stairway must be fire-isolated (Part D2),
• construction requirements (Part D3)
• features for stairs provided for people with a disability (Part D4).

To see Section D in full, visit: https://ncc.abcb.gov.au/editions/ncc-2022/adopted/volume-one/d-access-and-egress/part-d1-access-and-egress
