An electrical driver can be used to provide electrical drive signals to a first and second electrically controllable optical privacy glazing structures. A first electrical drive signal can be applied to the first privacy glazing structure and a second electrical drive signal can be applied to the second privacy glazing structure. Applying the first and second electrical drive signal can comprise temporally staggering delivery of the first and second electrical drive signals such that a peak power draw and/or a peak current draw from the first privacy glazing structure is temporally offset from a peak power draw and/or a peak current draw from the second privacy glazing structure. Staggering can include delaying the application of one electrical drive signal relative to the other, phase shifting one electrical drive signal relative to the other, or a combination thereof.

Various embodiments herein relate to methods, structures, tools, installation systems, etc. for retrofitting a new electrochromic window in a pre-existing window recess. In many cases, the new electrochromic window is installed parallel to a lite of a pre-existing window, with the resulting structure including the new electrochromic window, the pre-existing window, and a pocket that forms between them. Installation of a new electrochromic window in tandem with a pre-existing window results in many benefits including improved insulation (e.g., due to the presence of the additional air pocket(s) and lite(s)), improved climate control (e.g., due to the ability to control the amount of sunlight entering the building via the electrochromic window), and enhanced aes thetics.

The invention relates to a method of providing vacuum insulating glass (VIG) units each comprising at least a first and a second glass pane and a plurality of support pillars distributed between opposing surfaces of said glass panes to provide a gap (8) between the glass panes. A plurality of pane elements are provided, and individual topographic representations (TOPREP_2a-TOPREP_2n) of each of said plurality of pane elements (2a-2n) are obtained based on input (4) from a measuring arrangement (3), and the topographic representations are stored in a data storage (DS). The stored topographic representations are processed and resulting surface distance characteristic between pairs of panes are estimated. Vacuum insulating glass (VIG) assemblies are thus provided based on estimated resulting surface distance characteristics. The invention additionally relates to a system for providing manufacturing layouts and a manufacturing facility.

The present invention provides an energy-saving plate and a method for manufacturing the same. The energy-saving plate of the present invention includes: at least one upper plate, at least one lower plate, at least one inner plate, and a plurality of support structures; a top edge of the upper plate and a bottom edge of the lower plate appear as a straight line; the inner plate is provided between the upper plate and the lower plate, and adjacent plates are separated by the plurality of support structures; an exhausting opening is provided at a lateral side of the inner plate, which is a through-groove inter-penetrating upper and lower surfaces of the inner plate; the periphery of the upper plate, the lower plate, and the inner plate are sealed via a sealing material, so as to form vacuum layers between the plate layers; an exhausting pipe is arranged in the exhausting opening, with which the exhausting opening is sealed together via the sealing material, an open-end of the exhausting pipe is located inside the exhausting opening, and a closed-end of the exhausting pipe is located outside the exhausting opening and is located in the space formed between the upper plate and the lower plate.
