Title 24 in California - for Animal Shelter

[Samardas]

Although the owner is going to use lights with sensor in the offices, he does not want to use the sensor for the dog shelter area in his new facility of about 1200 Sq Ft. According to him, since the dogs will be running around in the main room, the sensor will not work. Any idea how to resolve this in Title 24 will be highly appreciated. Thanks a LOT, Samar

either occupancy sensors, or a timeclock are necessary.

occ sensors won't work, so that leaves a timeclock.
you could use a manual on occ switch, but once turned on,
it would never turn off. auto on is a complete nonstarter.
unless you used a wall mounted sensor that wouldn't
trigger with animal sized critters moving around. that's
pretty iffy. dual technology will use the infrared signature
to keep the lights on. nLight uses sound to maintain the
lights on. not gonna work well in a kennel.

for a small occupancy, a straight 2 channel 365 day timeclock
T 20 listed, with a 2 hour wind up bypass timer is probably
your most economical solution. intermatic is my first choice,
as they are easy to program, and bulletproof. use one channel
for interior lighting, with a contactor for multiple circuits, and
the other one for exterior signage. you could also use an nLight
system with a gateway, and make the animal area timed, and
the office area occupancy.

exterior lighting on the structure also need motion sensors.
as animal facilities are often standalone structures, that may
be a consideration.

i do T24 lighting certifications. send me a PM if you want
to discuss making this thing compliant before you install
everything. of late, i'm running into a lot of designs that
are drawn in a way that can't easily be made to comply.
in the last week, i've had three jobs not certify, as they
were drawn noncompliant, and installed as drawn.

IR occupancy sensors should work for dogs, unless they are robot dogs...

And why would you want the lights on 24/7? Slightest little thing that disturbs the pups will have them running around and your lights turning on.

Then you put in a switch or a time clock and turn them off...

Don't over think this. Title 24 doesn't say you can't have a switch. It says that IF the switch was left on and the room is UNOCCUPIED, the lights have to turn off automatically. Nothing says you must turn them ON automatically, in fact that might defeat the purpose in this case.

And I don't think that just the absence of humans makes the room unoccupied under the energy code!
And what about grow rooms?

Good question. Not germane to this discussion about animal shelters, but it is a good question that I don't think has definitive answers yet. I've seen a lot of chatter about it, and some cities have passed ordinances making them commercial properties, subject to ALL the rules and regs. But how does one classify the building? Warehouse? Factory space? I don't know, because those space definitions make assumptions about expected lighting levels, i.e. 5W/sq. ft. and I'm sure that for a grow operation, it's going to be higher. But the light IS part of the process, not a "convenience" for people entering the room. Might make for an interesting discussion when someone comes up against it...

That is how I think it needs addressed, There are other "processes" that need light or even a specific kind/type of light.

Some livestock operations even want to control light levels, both light and dark periods for better production purposes.

Mood lighting for husbandry barns??? :ashamed:

I do electrical for farmers and don't always understand everything that goes into production - but sometimes I think the answer is yes.

I have wired poultry buildings in the past and though the finish buildings usually have quite a bit of natural light, brooder houses are pretty closed other then ventilation openings, they are particular about lighting time in those facilities, not just on time but off time as well, the birds need dark to make them want to rest (which is needed) and light to make them active - AFAIK they don't feed and drink much when it is dark.

in the last week, i've had three jobs not certify, as they
were drawn noncompliant, and installed as drawn.

just looked at prints on two new ones today. make that five
noncompliant designs.

what's killing most of them is the exterior lighting now has
the same strategy as pole lighting in the parking lot.

if nobody is around for 15 minutes, the light dims 50%.
that means each side of the building is a separate zone,
and has an occupancy sensor, or the fixtures have to have
individual occupancy sensors.

then... there was the one with 170 track light heads in an
area, the ONLY lighting in the area, a food emporium dining area,
and the electrical engineer is blowing his whistle, saying
it's "display lighting", and does not need daylighting.

sorry. he needs a sharper pencil.

why is this a problem? the specified lighting is not dimmable.
daylighting requires dimming, and any space over 100 sq. ft.
needs full range dimming. not A-B switching.

nobody asked. durn shame. it's all installed. final inspection,
lighting controller programming, and certification is thursday.
not in that order, BTW.

durn shame.
