NFPA 13, 2007 8.1.1 (1) REQUIRES SPRINKLERS THROUGHOUT A.8.1.1 This standard contemplates full sprinkler protection for all areas including walk-in coolers, freezers, bank vaults, and similar areas. Other NFPA standards that mandate sprinkler installation might not require sprinklers in certain areas. Based upon experience and testing, sprinklers have been found to be effective and necessary at heights in excess of 50 ft (15.2 m). For a building to meet the intended level of protection afforded by NFPA13, sprinklers must not be omitted from such high ceiling spaces. The requirements of this standard should be used insofar as they are applicable. The authority having jurisdiction should be consulted in each case. A building is considered sprinklered throughout when protected in accordance with the requirements of this standard.
IFC 903.3.1.1 NFPA 13 sprinkler systems. Where the provisions of this code require that a building or portion thereof be equipped throughout with an automatic sprinkler system in accordance with this section, sprinklers shall be installed throughout in accordance with NFPA 13 except as provided in Section 903.3.1.1.1. 903.3.1.1.1 Exempt locations. Automatic sprinklers 903.3.1.2 NFPA 13R sprinkler systems. Where allowed in buildings of Group R, up to and including four stories in height, automatic sprinkler systems shall be installed throughout in accordance with NFPA 13R. 903.3.1.2.1 Balconies and decks. Sprinkler protection 903.3.1.3 NFPA 13D sprinkler systems. Where allowed, automatic sprinkler systems installed in oneand two-family dwellings shall be installed throughout in accordance with NFPA 13D. 903.3.2 Quick-response and residential sprinklers. This was just to show that "Throughout" means different things in different parts of the code. Also there are many "Exceptions" in the IFC to what shall be sprinklered, one exception is a non-combustible room with non-combustible contents. If you're not required to protect a non-combustible occupiable room, why would you be required to protect a non-combustible concealed space above that room?

His reasoning varies from the presence of HVAC, electrical, catwalks, etc... Can anyone provide me with a definition for the wording "throughout" as found in NFPA 13?
