This chapter provides an overview of the application of performance-based approaches to the fire safety design of timber buildings. Performance-based design methods are relevant for the design of tall timber buildings and other timber buildings that vary from accepted prescriptive solutions. Performance-based design approaches are commonly categorised as deterministic or probabilistic methods and should be applied in accordance with the applicable regulations, building codes and standards. This chapter provides references to detailed information that should be consulted when undertaking performance-based designs.
