This document discusses fire design practices in Germany. It provides an overview of hhpberlin, a fire safety engineering firm, and their services. It then discusses performance-based design methods and the national annex of Eurocodes 1-1-2, which provides simplified natural fire models, input data for natural fire models including a new safety concept, and guidelines for validating fire safety calculation programs. Examples of structural fire safety design projects in Germany are also listed.

10. Application of perfomanced based method requires emphatic approval of the building authority and the fire brigade

11. Performance based design is conducted by Eurocodes
