• Poor light quality (over/under-lit areas)!

o Overlighting wastes money!

o Underlighting compromises safety!

• No dimming – creates jarring shifts in light levels!

• Circuit-level controls not granular enough for

savings or performance requirements!

Automatic Shades

C402.3.1

Building Envelope Requirements

C402.3.1 Maximum area.

The vertical fenestration area (not including opaque doors

and opaque spandrel panels) shall not exceed 30 percent of

the gross above-grade wall area.

C402.3.1.1 Increased vertical fenestration area with

daylighting controls.

In Climate Zones 1 through 6, a maximum of 40 percent

of the gross above-grade wall area shall be permitted to be

vertical fenestration, provided:

1. No less than 50 percent of the conditioned floor area is

within a daylight zone;

2. Automatic daylighting controls are

installed in daylight zones; and

3. Visible transmittance (VT) of vertical fenestration is

greater than or equal to 1.1 times solar heat gain coefficient

(SHGC).

C405.2.2.1

Automatic time switch control devices.

• Automatic time switch controls shall be installed to control lighting in

all areas of the building. ( Except where you have Occ

Sensors )

C405.2.2.3

Daylight zone control.

• Switched separately from non-daylit zones

• Up to 2500 sq ft per zone

• Manual controls are acceptable

C405.2.2.3.1 Manual daylighting controls. Manual controls shall be installed in daylight zones unless automatic controls are

installed in accordance with C405.2.2.3.2 Automatic daylighting controls.
