Horticultural lighting in greenhouse spaces shall be controlled by a device that automatically turns off the horticultural lighting at specific programmed times.

9.4.4.2 Luminaires in indoor grow spaces used for horticultural lighting shall have a PPE of at least 1.9 µmol/J for integrated, nonserviceable luminaires, or a PPE of at least 1.9 µmol/J for lamps in lumi- naires with removable or serviceable lamps . Horticultural lighting in indoor grow spaces shall be controlled by a device that automatically turns off the horticultural lighting at specific programmed times.

Exception to 9.4.4.2: Indoor grow buildings with less than 40 kW of connected load for horticultural

lighting shall have a PPE of at least 1.7 µmol/J for integrated, nonserviceable luminaires, or a PPE of at least 1.7 µmol/J for lamps in luminaires with removable or serviceable lamps .

9.5 Prescriptive Compliance Path. Interior lighting power shall comply with either Section 9.5.1 or 9.5.2. Lighting control requirements shall comply with Section 9.4.1 and Tables 9.5.2.1-1 and 9.5.2.1-2.

9.5.1 Building Area Method Compliance Path . Use the following steps to determine the interior light- ing power allowance by the Building Area Method:

a. Determine the appropriate building area type from Table 9.5.1 and the corresponding LPD allowance. For

building area types not listed, selection of a reasonably equivalent type shall be permitted. b. Determine the gross lighted floor area in ft [2] of the building area type. c. Multiply the gross lighted floor areas of the building area types times the LPD .
