consequences that need to be avoided to fulfill the design objectives, and include
realistic values that are capable of being evaluated or measured using existing
engineering tools and methods.
The performance criteria must be a combination of the life safety
and property protection criterion, along with criteria developed from stakeholder

Performance-Based Fire Protection Analysis and Design of Buildings provide
guidance regarding the development and evaluation of appropriate performance
Design Fire Scenarios.
Document complete descriptions of the reasoning, intent, and details of all
required and stakeholder defined fire scenarios. Use realistic and accurate fire
scenarios, with respect to all fire elements, including initial fire location, early rate
of growth in fire severity, and smoke generation. Indicate in the description of the
fire scenarios all applicable data, characteristics and assumptions, which must
remain consistent between all fire scenarios. Ensure the omission of certain
details will not reduce the reality of the proposed design fire scenario. The design
engineer must justify any design fire scenario data that is omitted or cannot be
considered by available evaluation methods, and this justification must be noted
and approved by the authority having jurisdiction.
Technical References and Resources [Methods of Evaluation].
Thoroughly document all technical references, including methodologies, data and
sources. Identify the scientific basis of each engineering calculation method or
model. Develop, review and validate these methods using a consensus, peer-
review process, or obtain from resource publications. Where the chosen
methods do not permit the incorporation of all data or do not accurately address
the incorporation of the data, perform a sensitivity analysis for any design,
performance criteria, or fire scenario data that cannot be included or used in the
chosen methods. Address all degrees of conservatism and factors of safety, and
clearly identify the limitations of the calculation methods. Any method whose
outcome is significantly altered by the omission of trial design or fire scenario
details will not be approved, and the omission of critical data is prohibited. The
use of proprietary and non-peer reviewed data or source is not permitted. The
authority having jurisdiction must approve the assessment methods, data, and
sources, and confirm the validity of all technical references and resources prior to
the design evaluation. Provide the technical reviewer, upon request, any
technical references or resources.
The performance criteria must be capable of being proved or
measured using existing engineering tools and methods.
