CSBR research cited in window technology article

The Center for Sustainable Building Research (CSBR) and its work are cited in "Tomorrow's Options for More Efficient Windows" by D. Scott Beaver writing for Prenova's The Energy Blog. Smart windows that utilize chromogenic (optical switching) glazings adapt to frequently changing lighting and heating and cooling requirements of buildings.

The CSBR studied a range of smart window systems, including a variation of the chromogenic technology where the glazing adaptation takes place by reorienting suspended particles: "Suspended Particle Device (SPD) windows utilize a thin, liquid-like layer in which numerous microscopic particles are suspended. In its unpowered state the particles are randomly oriented and partially block sunlight transmission and view. Transparent electrical conductors allow an electric field to be applied to the dispersed particle film, aligning the particles and raising the transmittance."
