Determining ft² for IECC 505.2.2.2

[chris kennedy]

Can anyone tell my why the second floor square footage is added to the first floor here? Second floor is a completely separate lease space, separately metered, no access from 1st floor tenant space. I'm trying to VE out a very pricey automatic shut-off lighting control system.

Thanks.

The total sq. ft of the building is pretty standard info on plans I see.

Of coarse, BUT, IMO the architect made a mistake. As stated the 1st and 2nd floors are completely separate lease spaces. so I want to use this;

FBC 13-202 BUILDING. Any structure that includes provision for any of

the following or any combination of the following: a space

heating system, a space cooling system, or a service water heating

system. For each purpose of this code each portion of a

building separated from other portions by a rated fire wall shall

be considered as a separate building. The term “building” shall

be construed as if followed by the words “or part thereof.”

To defeat this;

FBC 13-415.ABC.1 Controls.13-415.ABC.1.1 Automatic lighting controls. Interior

lighting in buildings larger than 5,000 square feet (465

m2) shall be controlled with an automatic control device

to shut off building lighting in all spaces.

FBC 13-202 may clear you based on the language on the bottom of project data in the clouded area. That may be what you want to hear, however..........

The reality is that it is NOT a fire wall as per the definition of firewall. I don't think you can separate these areas as separate buildings horizontally. Look up the definition of "Fire Wall" or "Firewall" and you will see what I mean.

In our jurisdiction, 505.2.2.2 would apply unless you took it to the appeals board.

Look up the definition of "Fire Wall" or "Firewall" and you will see what I mean.

FIRE WALL. Fire-resistant wall, having protective openings,which restricts the spread of fire and extends continuously

from the foundation to or through the roof, with sufficient

structural stability under fire conditions to allow collapse of

construction on either side without collapse of the wall.

Crap.ops Thanks Jeff.
