NFPA 220, Standard on Types of Building Construction, defines types of building construction based on the combustibility and the fire resistance rating of a building's structural elements. The image below gives an example of how you might see this rating in a document and explains the different types as well as the following numbers. NFPA 101: Life Safety Code 2015 is a reference used for strategies to protect people based on building construction, protection, and occupancy features that minimize the effects of fire and other related hazards. Both of these aspects are essential to fire and life safety.

This standard promotes protection from fire and its associated hazards by defining types of building construction based on the combustibility and the fire resistance rating of their structural elements. It needs to be able to produce a heat value less than 3,500 BTU/lb when tested in accordance with NFPA 259.

Also, any inherently noncombustible materials can be considered noncombustible without having to be tested. NFPA 101 does not include minimum requirements for the height and area of a building based upon construction type for all occupancies, but rather tends to limit such requirements to those occupancies in which evacuation times are expected to be longer (i.e., assembly occupancies, like a theater) or those occupancies in which the emergency procedures are likely to involve the relocation of ⦠The outstanding difference between the two occupant loads is in how each code directs the application of the loading factors.

If the materials don’t meet the definition of limited-combustible or noncombustible then it is a combustible material. (For context paper has a heat value of approximately 7,000 BTU/lb, wood is about 10,000 BTU/lb while most plastics are in the 15,000 to 22,000 BTU/lb range). Minimum construction requirements are established to help maintain structural integrity for the time needed for evacuation or relocation to a safe location in the building. Types I, II, III, and V are each subdivided into two subtypes according to the relative fire Second Digit (0X0): Columns, beams, girders, trusses and arches, supporting bearing walls, columns or loads from more than one floor.

Understanding and complying with construction type requirements is the first step in creating a safe built environment. Type IV construction is that type of construction in which the exterior walls are of noncombustible materials and the interior building elements are of solid wood, laminated wood, heavy timber (HT) or structural composite lumber (SCL) without concealed spaces. When codes and standards refer to the type of construction required or permitted there are three numbers in parenthesis that follow the type of construction.
