2.6 Design scenario (VS)
Vertical fire spread involving external cladding or external openings
Design scenario in brief
A fire source exposes the external wall or arrangement of openings in a building and leads to significant vertical fire spread.
Demonstrate that the building’s external cladding / facade and arrangement of openings in the building do not increase the risk to life resulting from a fire beyond that for a similar building complying with the Deemed-to-Satisfy Provisions.
2.6.1 Design scenario description
This design scenario applies to all buildings where there is a risk of vertical fire spread.
This design scenario is not concerned with building-to-building fire spread across a relevant boundary, as this is addressed in the design scenario: HS (see 2.5).
Demonstrate compliance with CV3.
