Abstract:
Different window assemblies can be fabricated and installed where the size of an electrical component is sized for a particular geometry of the window assembly. In a particular embodiment, an energy rating, which may include an energy consumption rate, a recharge rate, a recharge capacity, an electrical current leakage rate, another suitable parameter, or any combination thereof, may be used when determining the size of the electrical component to be used. If needed or desired, one or more trim panels can be used to cover portions of a window assembly to make the window more aesthetically pleasing.

In another aspect, a method of operating an apparatus can include receiving an input corresponding to state information; and at a control device, in response to receiving the input, selecting a scene from a collection of scenes. The collection of scenes may be validated before using the scenes. The scenes may be validated based on physical configuration of the controlled space, preferences of the occupant, or the like. Still further, scenes can be changed to allow for the passage of time or an illusion of changing sky conditions when sky conditions are not changing. The apparatus and method can be simpler to understand and implement as compared to complex control strategies.
