At least 6% of parking spaces must be provided with electrical raceways originating at the building's electrical power distribution panels to facilitate future installation of electric vehicle charging stations. Electrical power distribution panels serving these raceways must be sized to supply the future charging stations based on a design load of not less than 40 amp per parking space at a supply voltage of not less than 208-240 volt, and have space reserved for future installation of a branch circuit overcurrent protective device. Raceways must terminate into a listed cabinet, box, or enclosure in close proximity to the proposed location of the electric vehicle charging station(s). Raceways may not be less than trade size 1 (nominal 1-inch inside diameter).

1101.4.4.5.1 "Daylighting" Requirements.
Not less than 35% of the floor area must be in the daylight area, as defined in Chapter 3. The definition of daylight area is modified so that partitions and other obstructions that are less than the ceiling height are disregarded. Daylight areas must be under skylights, under roof monitors, or in the primary or secondary sidelighted areas and must meet at least one of the following requirements:
a. The combined area of the skylights within the space is not less than 3% of the calculated daylight area under skylights.
b. The space has a skylight effective aperture of not less than 1%.
c. The combined area within the space of any vertical fenestration in roof monitors is not less than 20% of the calculated daylight area under roof monitors.
d. Primary sidelighted areas have a side- lighting effective aperture of not less than 0.15.
e. Secondary sidelighted areas have a side- lighting effective aperture of not less than 0.30.
1101.4.4.5.2 "Simulation" Requirements.
The computed area-weighted sDA may not be less than 30%. The sDA within each space must be calculated in accordance with the methodology of IES LM 83. Calculations must be made on the basis of 28 fc (300 lux) for all spaces, with the exception of the following space types, which must be calculated on the basis of 14 fc (150 lux): health-care patient rooms, post-office sorting areas, gymnasia, big box retail, transportation facility terminal ticket counters, airport concourses, and non- refrigerated warehouses.
Exceptions:
a. A space used for tasks or activities requiring routine dark conditions for more than 4 daytime hours per day.
b. A space where the height of existing facing structures above the vertical fenestration is not less than twice the distance between the vertical fenestration and facing structures, measured from the top of the glazing.
1101.4.4.5.3 Excessive Sunlight.
The ASE, calculated with a threshold of 93 fc (1000 lux) and 250 hours, may not exceed 10% of the floor area.
Exceptions:
a. Spaces less than 250 ft2 (23 m2).
b. Vertical fenestration with automatically controlled shading devices in compliance with ICC version of § 801.5.1.2, Exception (2).
c. Vertical fenestration with automatically con trolled dynamic glazing in compliance with ICC version of § 801.5.1.2, Exception (3).
