Building and Energy Code Andy Kedzuch Scott Lowe Anlage
Building Code Bauordnung für Berlin (BauO Bln)
Each State has its respective building code based off of the Federal building code
§ 17 Building Products
§ 21 Building Styles
§ 26 Fire Resistance of Building Materials
§ 27 Bearing Walls and Supports
Bearing and permanent walls and supports must stand sufficiently long in case of fire.
In buildings of building class 5 must be fire proof
Buildings of building class 4 must have a high fire resistance
In buildings of building class 2-3 they have to be fire resistant 3 Satz 2 gilt (sentence 2 takes effect)
For attic floors for where occupancy is possible § 29 abs. 4 remains un effected
Not for balconies, excluding open walkways and service corridors
In basement level bearing and permanent supports must…
In buildings in classes 3-5 they must be fire proof
In buildings in classes 1-2 they must be fire resistant
Bearing and permanent walls and supports from any garage level with and area of up to 100m 2 as well as buildings in accordance with § 62 abs. 1 nr. 1 Letter A must be constructed of non-flammable building materials.
§ 28 Exterior Walls
Exterior walls and parts exterior walls such as parapets and aprons must be constructed to limit the spread of fire and must stand sufficiently long in case of fire
Non-bearing exterior walls and non-bearing parts of exterior walls do not have to be constructed of non-combustible materials as long as they are fire resistant.
§ 29 Partitions
Partitions after paragraph 2 must be full or partial high partition walls and must stand sufficiently long in case of fire.
Partitions are required…
Between units as well as between rooms of a different use excluding required hallways
Completely enclose rooms with explosion of increased fire danger.
Between habitable and non-habitable spaces
Partition walls after paragraph 2 NR. 1 and 3 must have the same fire withstanding properties of structural and stiff building parts of the same floor.
The partition walls after paragraph 2 are to extend up to the roof deck, in rooms of this type the roof deck, the structural members, and stiff members must be fire resistant. In attic spaces where partitions extend to roof deck, roof deck as well as structural elements must be fire resistant.
Openings in partition walls after paragraph 2 are only allowed when they are appropriate size and number for the space. They must be fire resistant and must be closed.
The paragraphs 1-5 don’t apply for residential building of building class 1-2
