FYI - I am trying to use 5.6K for the small self-storage units and 8.0 everywhere else (corridors and larger 10 x 10, 10 x 15, 10 x 20, etc.) in order to reduce pipe sizing.
They are all separate compartments with heads in every individual unit. -----Original Message----- From: Sean Lockyer Sent: Friday, October 29, 2021 10:10 AM To: [email protected] Subject: Mixing of K-Factors in self-storage facilities NFPA 13 generally discourages the use of mixing K-Factors in a system; however, the mixing of K-Factors is allowed in certain circumstances, namely in section 23.4.4.9.3 where it allows such use for small rooms and enclosures. In a self-storage facility, the small 5' x 5' storage units would not be considered "small rooms" as they are not light hazard (once again, per the strict definition as layed out in chapter 3). However, would you be able to consider the small units as enclosures since they are completely separate rooms from the other, larger self-storage units ? Sean Lockyer Project Designer 6817 N.
