The ICCPC also makes a good template for evaluating alternate methods and materials. How do you make a decision if something is "equivalent" without protocols to evaluate it? The ICCPC gives you that opportunity.
BTW, National Fire Academy class "Evaluating Performance Based Designs" covers this in great detail:

The performance code is for those unique structures and projects that do not fit the normal building code and can budget for alot of engineering to show that the building provides acceptable performance.
As a code official be very wary in the discussions about the design parameters and the methods to show compliance as the designers often want to design to defend against little fires not worst case ones.
IE we provide police with vests that will stop up to a 357 Magnum or so pistol bullet, but if the perp has a rifle all bets are off.
A small rammed earth structure or house would be better handled using the alternative methods section of your administrative code.

Thank you both, for taking time to reply.
Now would a Rammed Earth structure be an example of a building where a designer would use the Performance Code?
Thank you, Rick

Great question; Builder Bob''s building products example is a good one, and another advantage of the Performance Codes, is when entirely new structural reinforcing methods are developed, like continuous steel strapping systems.
Codes and Product Manufacturers prescribe certain methods of installing their reinforcing products, as per their Engineers and Testings. New systems that applies the same products in alternative methods, placements, and designs of these pre-approved products will require an additional verification by a Project Civil/Structural Engineer, which the Performance Code provides for.

when the prescriptive requirements of the IBC become unfeasible.... ex. Manufacture of fiberglass rosin panels was limited to travel distance allowed by the prescriptive requirements of the IBC, The manufacture used the performance based codes to "prove" the design would work with tradeoffs to allow the extra 50 feet of travel they needed to make their panels economically feasible for the lenght they wanted to make.
