|---|---|
| Interior Space Type and LPA | Controls |
| All_spaces_ in office_buildings_ other than parking garages The total_LPA_for the_ building_other than parking garages shall not exceed 0.56 W/ft2. | All lighting shall be_automatically_controlled to turn off when individual_spaces_are either unoccupied or scheduled to be unoccupied. (Exception: Lighting load not exceeding 0.02 W/ft2 multiplied by the gross lighted area of the_space_ shall be permitted to operate at all times.) Each_space_ shall have a_manual control device_ that allows the occupant to reduce lighting power by a minimum of 50% and to turn the lighting off. |
| Office_spaces_ 150 ft2, classrooms, conference rooms, meeting rooms, training rooms, storage rooms, and break rooms | These_spaces_ shall also be controlled by_manual_-ON occupant sensors. |
| Office_spaces_ >150 ft2 and restrooms | These_spaces_ shall also be controlled by_occupant sensors_. |
| Stairwells and corridors in office_buildings_ | These_spaces_ shall also be controlled by_occupant sensors_ that reduce the lighting power by a minimum of 50% when no activity is detected for not longer than 15 minutes and be controlled to turn off when the_building_ is either unoccupied or scheduled to be unoccupied. |
| Parking garages: The_LPA_shall not exceed 0.14 W/ft2 for the interior parking floors. Uncovered floors of a garage shall use_LPA_and control requirements in Table 9.3.2 for parking lots. | All lighting shall be controlled by_occupant sensors_. Controls shall reduce the power by a minimum of 50% when no activity is detected for not longer than 15 minutes. No device shall_control_ more than 3600 ft2. |

|---|---|
| Interior Space Type | Controls |
| All_spaces_ in retail_buildings_ other than parking garages The total_LPA_for the_building_other than parking garages shall not exceed 0.70 W/ft2. | All lighting shall be_automatically_controlled to turn off when individual_spaces_are either unoccupied or scheduled to be unoccupied. (Exception: Lighting load not exceeding 0.02 W/ft2 multiplied by the gross lighted area of the_space_ shall be permitted to operate at all times.) Each_space_ shall have a_manual_ control device that allows the occupant to reduce lighting power by a minimum of 50% and to turn the lighting off. |
| Sales area | These_spaces_ shall also be_automatically_controlled to • reduce the_general lighting_ power by a minimum of 75% during nonbusiness hours, • to turn off all lighting other than_general lighting_ during nonbusi- ness hours, and • by_continuous daylight dimming_ controls in_spaces_ with_toplighting_. |
| Stock rooms, dressing/fitting rooms, locker rooms, and restrooms | These_spaces_ shall also be controlled by; auto-ON or_manual_-ON occupant sensors, and_continuous daylight dimming_ controls in spaces with_toplighting_. |
| Office_spaces_, conference rooms, meeting rooms, training rooms, storage rooms, break rooms, and utility_spaces_ | These_spaces_ shall also be controlled by;manual-ON occupant sensors, and_continuous daylight dimming_ controls in_spaces_ with toplighting. |
| Stairwells and corridors in retail_buildings_ | These_spaces_ shall also be controlled by_occupant sensors_ that reduce the lighting power by a minimum of 50% when no activity is detected for not longer than 15 minutes and be controlled to turn off when the_building_is either unoccupied or scheduled to be unoccupied. |
| Parking garages: The_LPA_shall not exceed 0.14 W/ft2 for the interior parking floors. Uncovered floors of a garage shall use_LPA_and control requirements in Table 9.3.2 for parking lots. | All lighting shall be controlled by_occupant sensors_. Controls shall reduce the power by a minimum of 50% when no activity is detected for not longer than 15 minutes. No device shall_control_ a more than 3600 ft2. |
