Daylight Center
CTAC's 1,000-square-foot Daylight Center accommodates classes, workshops, meetings, and demonstrations of sustainable buildings and is considered a California High Performance School (CHPS) model.
The center also incorporates several energy-efficient technologies, including:
Tube Skylights
Tube skylights introduce daylight directly from the roof. When coupled with a daylight harvesting system, electric lighting can be dimmed when sufficient daylight is present. When lighting levels need to be low (for presentations), the tube skylights are equipped with dimmers which allow the daylighting to be reduced.
Light Shelf
An exterior "light shelf" reflects sunlight into the building, illuminating the ceiling and increasing room brightness. The high-efficiency direct/indirect lighting systems are controlled by photo-sensors that dim as natural light levels increase, resulting in energy savings.
Displacement Ventilation
This technology delivers cooled or heated air at floor level at a lower velocity than standard vents and at a slightly higher temperature to promote improved comfort, indoor air quality and energy savings.
High Performance Glass
The center's upper clerestory windows are dual-pane, low-E, with 68% light transmittance for daylighting application. The lower view windows are also dual-pane, low-E, but with a darker tint (40% light transmittance) to reduce glare, maintain visual comfort and thermal efficiency.
Cool Roof
The reflective white color of the single-ply thermoplastic roof material on the building is designed to reduce heat gain in the building during the summer to create a "cool roof."
The Daylight Center hosts classes in energy-efficient technologies.
