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 - TECHNOLOGYOVERVIEWOccupancy/ vacancy sensor anatomy & specificationsMust be manual-on/automatic-off (can also be turned 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 nightlightImpact-resistant lens and switchA compliant sensor must have all of the following features:Optional features to consider when choosing an occupancy or vacancy sensor:PART 1 - TECHNOLOGYOVERVIEWDimmer anatomy & what to specifySpecify the correct load amount:Specify the aesthetic quality: line voltage low voltage 3 way dimmers (ex. hallway applications) Various finishes & colors Toggle vs. slidePART 1 - TECHNOLOGYOVERVIEWPart 2 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 Sensor must view the space that is illuminatesDo not need to be concerned with where to place the motion sensorLights can be left on for an extended period of timeDo not have to worry about motion sensor lights turning on and off at undesired timesBenefits of fluorescent lighting fixturesResponds to motionAutomatically turns lights on/off, lights are not left of unintentionallyAdded security to areas around the homeUse standard incandescent lampBenefits of incandescent/ photocell motion sensorLow-rise = 3 or less storiesCommon areas of low-rise residential buildingswith four or more dwelling unitsCompliant high efficacy lighting (preferably with a photocontrol or time clock):-Fluorescent-Metal halide-High pressure sodiumEach and every permanently installed fixture must comply with the standards, by means of being high-efficacy or controlled by a occupancy sensor. Occupancy sensor must be directly on the walkway and/or view the entire spaceResidential parking lots for eight or more vehiclesLight fixtures must be controlled be a photocontrol or an astronomical time switch that turns lights off when daylight it presentMust meet the power density limits for non-residential lighting standards (for more information see 2005 Nonresidential Manual, section 147)Fixtures with lamps rated over 175 watts shall be designated as cutoff; limiting light emitted upwardsUniform lighting is desired to help eliminate shadows in corners and provide a sense of safety
