What is a Performance Solution?
In the context of the NCC 2022, a Performance Solution is an alternative method for achieving compliance with the building code’s Performance Requirements. Unlike the Deemed-to-Satisfy (DTS) provisions, which provide a prescriptive pathway to compliance, a Performance Solution allows for flexibility in how compliance is achieved. This approach is particularly useful when dealing with unique building designs, site-specific conditions, or when using innovative materials and construction methods.

When is a Performance Solution Required?
A Performance Solution is typically required when a project cannot fully comply with the DTS provisions of the NCC. For example, consider the following scenarios:
- Ceiling Heights: The NCC generally requires ceiling heights of at least 2.4 meters in habitable spaces. However, in certain renovation or conversion projects, achieving this height might be impractical due to existing structural constraints. A Performance Solution can be developed to demonstrate that a slightly lower ceiling height still provides adequate amenity and safety for occupants.
- Lack of Step Down to Exterior: The NCC mandates a minimum step down from interior habitable spaces to exterior areas to prevent water ingress. If a site’s existing conditions do not allow for this step down—such as in a garage conversion where the floor level cannot be altered— a Performance Solution can propose alternative measures like enhanced drainage systems or weather seals to achieve the same level of protection.
These are just a few examples of where a Performance Solution can be invaluable, providing the flexibility needed to meet compliance without compromising on safety or functionality.
