Embodiment Construction

[0049] The represented control system 1 is intended to manage both the visual comfort of the users present in the rooms of the building and the thermal conditioning of the rooms.

[0050] The room is equipped with a number of active glazing V with electrically controllable optical transmission properties that can be controlled by the control system 1 k .

[0051] The system 1 is concerned with a single room but more generally the control system 1 can control the lighting of many rooms of a building.

[0052] Active glazing V kare glazings, such as electrochromic glazings, for example comprising electrochemically active devices that react chemically to powered applications. The optical transmission of such glazings is thus controlled electrically.

[0053] The expression "optical domain" should be understood to mean the visible, infrared and ultraviolet domains.

[0054] There are many electrochromic glazings.

[0055] These are generally divided into three categories: "al...

Abstract

The invention relates to a system for controlling the optical transmission of a plurality of glazings Vk with electrically controllable optical transmission properties, comprising at least one spatial brightness sensor for providing respectively for different spatial regions forming a subset Xi of the set X At least one value representing luminance and thus providing a map L of luminance in which a subset Li of L is associated with a set Xi, and a control unit comprising a memory storing in the memory capable of controlling each of the The procedure for optical transmission of glazing is described. The program is able to define a map A of spatial regions Aj of glare from a map L of luminance, a map O of spatial regions Om with electrically controllable brightness can be used, where each subset Om is associated with one or more The glazing Vk is associated with and the optical transmission of each said glazing Vk with electrically controllable optical transmission can be controlled according to A and O.

Description

technical field [0001] The present invention relates to the field of controlling brightness in building interiors. Background technique [0002] The vitrage of a building has the disadvantage of contributing to the heating of the building in summer and to the cooling of said building in winter. [0003] Since the mid-1990s, a wide variety of insulating and solar control glazing has been developed by the glass industry. With "low-E" or "reflective" coatings now on the market, high levels of thermal insulation and solar protection can be obtained. [0004] However, these glazings have fixed properties that cannot be adapted to temperature and sunlight conditions. [0005] Glazing with electrically controllable optical transmission solves this problem. [0006] These so-called "smart" glazings have optical properties that can be modified electrically. [0007] The article entitled "Effect of switchable glazing on discomfort glare from windows" (Building Environment 44 (2009...
