comply with Californias 2005 Title 24 energy code.The information
and graphics used for this presentation originated from
the:Residential Lighting Design GuideBest practices and lighting
design to help builders comply with Californias 2005 Title 24
energy code.Additional hard copies are available at local utilities
and can be downloaded at:www.cltc.ucdavis.eduThe Guide provides a
practical cook book approach for lighting codes compliance and
design.Includes:- Detailed explanation of the code- Technical and
compliance information - Lighting design examplesGuide simplifies
and assists in developing compliant, quality lighting designs.The
official code can be found on the California Energy Commissions
website at:http://www.energy.ca.gov/title24Or you can

lighting technologies that apply to Title 24PART 2:Lighting Design
Guide example applications oflighting and control technologies in a
room by room scenarioPART 1 - TECHNOLOGYOVERVIEWDimmers, which are
already common in many residential applications, allow the room
occupants to lower the room lighting (and thus the power used) as
desired.These lighting fixtures are designed and built to operate
only energy-efficient light sources, such as fluorescent T8 lamps,
compact fluorescent lamps (CFLs), and high intensity discharge
(HID) lamps.Occupancy sensors, vacancy sensors, motion sensors, and
daylight sensors are all devices that automatically turn off the
lights in response to conditions that they sense or see.You will
use three main technologies to comply with the guide, they are:I n
general, the following are high efficacy luminaires:Fluorescent and
CFL fixtures with electronic ballastsFixtures with high intensity
discharge (HID) lampsAny fixture with incandescent lampsAny fixture
with a screw base CFLI n general, the following are NOT high
efficacy luminaires:High-efficacy luminairesPART 1 -
TECHNOLOGYOVERVIEWHigh-efficacy luminaires: What to specifySpecify
the appropriate light output:Rule of thumb: You should be able to
lumen match the incandescent fixtures by specifying fluorescent
systems that use one-third or one-fourth as much power.Specify the
appropriate lamp wattage:Depending on what lamp wattage is chosen
(with the same number of fixtures) you could have a much brighter
space or a much darker space in comparison to an existing
incandescent space.For example:8 (65 watt) BR lamps x 750 lumens
per lamp = 7100 lumens6 (26 watt) CFL lampsx 1300 lumens per lamp =
7800 lumens10 (13 watt) CFL lampsx 600 lumens per lamp = 6000
lumens Specify the appropriate color:Warmer lamp colors (CCT =
2700-3000K) = closest match to incandescentPART 1 -
TECHNOLOGYOVERVIEWHigh-efficacy luminaires: What to specifyFor
recessed fixtures in IC applications look for: Ballasts that are
rated for higher operating ranges Fixtures configuration that
limits heat to the ballastSpecify electronic ballasts: Mandated in
all high-efficacy luminaires of 13 W or higher Eliminates the
flicker and hum associated with some magnetic ballasts.PART 1 -
TECHNOLOGYOVERVIEWFixture labels for compliance and qualityENERGY
STAR ENERGY STAR definition of high-efficacy has been changed to
match Title 24 BUTno way to tell the old ENERGY STAR fixtures fro
the new ENERGY STAR fixtures Has requirements to guarantee minimum
standard of qualityTitle 24 Indicates compliance with high efficacy
requirements for Title 24 Label not required for complianceAirtight
label for fixtures in insulated spacesNOTE: For complete airtight
compliance, the installation must also be airtight with either
sealed gasket(s) or caulking. For more information see the
Residential Compliance Manual, Chapter 6.10. ASTM E283 label
certifies airtight in accordance with ASTM E283 testing & Title
24. If label does not specify ASTM E283 testing, additional
documentation will be needed to indicate the fixture has been
tested and certified in accordance with ASTM E283.PART 1 -

off manually)Time delay cannot be greater than 30 minutesCannot be
locked in a permanent onstate (no on override)Outdoor sensors can
be automatic-on/off but must also include a photocell that keeps
the lights off during daylight hoursEnergy-efficient LED

consists of floor plan examples and detailed explanations of the
code.The examples will cover the following areas: Kitchen Bathroom
(same requirements apply to garages, laundry roomand utility room
Other spaces (bedroom, living/dining room, attic & hallway)
Outdoor spaces Multi-family common areas Multi-family parking lot
areasThe first switch no longer has to be a fluorescent light
fixtureFluorescent and incandescent light fixtures MUST be
controlled separatelyThe quantity of light fixtures is not
regulated by the code, just the wattage (wattage applies to
kitchens only!)50% of the overall wattage MUST be fluorescentNook
lighting must be on a separate switch in order to be counted as an
other space and not part of the kitchenLighting that is part of an
appliance is not regulated by the codeIf a fixture can accept
various lamp wattages, its wattage for the sake of code compliance
is the highest relamping rated wattage designated by the
manufacturer on a permanent, factory-installed Underwriters
Laboratory (UL) label (peel-off labels are not permitted).Kitchen:
As defined by the California Energy Commission, a room or area used
for cooking, food storage and preparation, and washingdishes,
including associated countertops and cabinets, refrigerator, stove,
ovens, and floor area. The first switch no longer has to be a
fluorescent light fixtureFluorescent and incandescent light
fixtures MUST be controlled separatelyThe quantity of light
fixtures is not regulated by the code.Bathroom: As defined by the
California Energy Commission, a room containing a shower, tub,
toilet, or a sink that is used for personal hygiene.Each and every
permanently installed fixture must comply with the standards, by
means of being high-efficacy or controlled by a manual-on occupancy
sensor. Occupancy sensors must be manual on/off and automatic
off.The maximum time delay to turn off is 30 minutes after the last
detected motion. (may feature a grace period which will allow the
lights to automatically turn back on within 30 seconds after they
have been automatically turned off.Sensors cannot have an override
allowing the light fixture to be continuously on.BedroomsEach and
every permanently installed lighting fixture must comply with the
standards, by means of being high efficacy, controlled by a
manual-on occupancy sensor, or controlled by a dimmer. Fluorescent
and incandescent light fixtures MUST be controlled
separatelyOccupancy sensors must be manual on/off and automatic
offSwitched outlets (half-hots) do not require special
controlsCeiling fans with incandescent light kits need one switch
for the fan and one dimmer/occupancy sensor for the lights.
(fluorescent - only one switch is needed, two is shown for
flexibility)Living & Dining RoomFor a more decorative option
use incandescent light fixtures and dimmer(s)Ceiling fans with
incandescent light kits need one switch for the fan and one
dimmer/occupancy sensor for the lights. (fluorescent - only one
switch is needed)Each and every permanently installed lighting
fixture must comply with the standards, by means of high efficacy,
controlled by a manual-on occupancy sensor, or controlled by a
dimmer. Switched outlets (half-hots) do not require special
controlsAtticEach and every permanently installed lighting fixture
must comply with the standards, by means of high efficacy,
controlled by a manual-on occupancy sensor, or controlled by a
dimmer. Warning: If an occupancy sensor can not see the entire
attic; the occupant could be left in the dark!Enclosed patioAn
enclosed (unconditioned) patio is considered an other space. Each
fixture must meet the code requirements. (high efficacy, dimmer,
occupancy sensor)Occupancy sensors must be manual on/off and
automatic offFluorescent and incandescent light fixtures MUST be
controlled separatelyHallwaysEach and every permanently installed
lighting fixture must comply with the standards, by means of high
efficacy, controlled by a manual-on occupancy sensor, or controlled
by a dimmer. Occupancy sensors must view the entire space (this
application may require three way switched as shown)Each and every
permanently installed fixture must comply with the standards, by
means of being high-efficacy or controlled by a outdoor motion
sensor. Outdoor motion sensors much have:- Automatic on/off
operation- Photocell to keep lights off duringdaylight hoursThis
part of the code covers all exterior lighting EXCEPT landscape
lighting that is not attached to the building and residential
parking lots or garages for eight or more vehicles.Outdoor sensors
also must comply with the maximum 30 minute shut off requirement
