22. Control System – Classroom
• Current Design
-2 momentary switches
-2 power packs
-one or more vacancy sensor
-lamp “a” and lamp “b”
controlled separately
-no daylight harvesting
- No dimming
-$500
• 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!
24. Control System – Classroom
• Q335
• Automatic assessment of ambient light!
• Gradual (imperceptible) adjustment!
• No jarring shifts in light levels!
• Consistent light levels across facility!
• No under-lit/over-lit areas!
-one dimming switches
-one controller for two or four
classrooms
-one or more vacancy sensor
-entire fixture work as one unit
-daylight harvesting
-smooth dimming

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).
