1. A surface structure adapted to have a first selectable state that is transmissive to the solar spectrum, and a second selectable state that restricts transmission of at least a part of the solar spectrum, the surface structure comprising:
- at least one layer comprising a hydrophobic surface and a fluid contacting at least a portion of the hydrophobic surface;
wherein a contact angle of the fluid on the hydrophobic surface is altered when a voltage signal is applied to the surface structure.

Abstract
Methods, systems, devices and/or apparatuses are provided that selectively reflect the infrared spectrum independent of other regions of the solar spectrum in order to actively manage solar heat gain across surfaces such as windows, skylights, roofs, siding and the like.

11. A window adapted to have a first selectable state that transmits at least 50% of the visible spectrum, and a second selectable state that reflects at least a portion of the near infrared spectrum, the window comprising:
-
an exterior layer; an electrofluidic layer operably coupled to the exterior layer, the electrofluidic layer adapted to selectively reflect at least a portion of infrared light; and an interior layer. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A window adapted to have a first selectable state that transmits at least about 50% of the visible and infrared solar spectrum, and a second selectable state that transmits less than about 10% of the visible spectrum and more than about 50% of the solar infrared spectrum, the window comprising:
-
an exterior layer; an electrofluidic layer operably coupled to the exterior layer, the electrofluidic layer adapted to transmit at least a portion of Infrared light; and an interior layer. - View Dependent Claims (21)
