A method of automatic proofing a document submitted for printing on a press having a digital front end includes inputting the document into a raster image processor to produce a post-RIP file. At least two components are bonded to each other by the applying heat to the heat bondable plastic material of one component. The transparent layer includes a first region including cadmium tin oxide; a second region including tin and oxygen; and a transition region including cadmium, tin, and oxygen interposed between the first region and the second region, wherein an atomic ratio of cadmium to tin in the transition region varies across a thickness of the transition region. Predicted and measured building energy load values are compared to determine if a preset difference threshold has been exceeded, in which case an alert signal or message is generated and transmitted to electronically andor physically signal a user.
