Egress Lighting In A Corridor

[north star]

@ ~ @

Hypothetically, I have a corridor with Emergency Lighting that
will come on with the loss of normal power......The "required"
level of foot candles is 1.0 for navigating through the corridor
and out of the bldg. when needed [ per 1006.2, `12 IBC ].

The "required" minimum amount of lighting to provide the 1 FC
will be through emergency circuitry on the existing lighting
fixtures, say every 4th light fixture in the corridor.

QUESTION: Is there a Code; Energy or otherwise, that states
that I cannot have all of the light fixtures in the corridor to
come on with the loss of normal power [ i.e. - having more FC
than required ] ?

I ask this question, because the Energy Nazi's & their Movement
want to impose their agenda on [ seemingly ] every aspect of
construction.

Please cite your sources if possible......Thanks !

Interesting question.

I can't imagine being penalized for having to much emergency lighting. I have been in projects where you could not tell the difference.

But, that was in the past. I have not heard of anything in the energy movement that would prohibit it, but?

Well look at it another way, under normal power the lights are on.

I maybe missing something.

I cannot think of any code language that would restrict the level of egress lighting. I would say it cannot be more that the normal energy consumption or light levels

As long as it does not exceed the 1 Watt per square foot or so that the IECC limits now...

steveray ( and others ),

What Code Section or Table states the limit of 1 watt
per sq. ft., and are Corridors and \ or Emergency Lighting
exempt from this 1 watt per sq. ft. ?

Thanks ya`ll !


Let the Energy drama continue...

mtlogcabin,

Which Edition of the IEEC are you referencing ?
In the `12, Table C405.5.2(2), ...lists Corridors at
0.7 watts, and Section C405.5.1, # 1.3 exempts
Emergency lighting from the total interior lighting
power allowances.

The `15 IEEC, Section C405.4.1 # 1.3 also exempts
Emergency lighting from the total interior power
allowances.

Office spaces were 1 in 2009....Now it is all broken up in 2012, but it is still right around there....Hadn't seen the exception, but hadn't had to fight it either. Can't think of where it might actually come up. Funny that they exempt "emergency" but exit signs are covered....

C405.4 Exit signs (Mandatory). Internally illuminated exit
signs shall not exceed 5 watts per side.

Exit signs on 24 hours?

the exemption means there is no maximum limit of the amount of watts used to provide emergency illumination...So the answer to your question is yes all the lights can be on during an emergency

When it comes to energy codes there is usually scoping that provides exceptions to the code for most life safety elements. It can be located in the overall scoping of the document, of the section or the code requirement itself.
