Abstract
A composite pane includes outer and inner panes joined via an intermediate layer, an electrochromic functional element with electrically controllable optical properties within the intermediate layer, wherein the total solar energy transmittance in the darkened state is higher than in the bright state and/or the energy transmittance in the darkened state is higher than in the bright state, and an infrared protection layer having at least one silver-containing layer and arranged on an interior-side surface of the inner pane facing the intermediate layer, on an interior-side surface of the outer pane facing the intermediate layer, or within the intermediate layer. The infrared protection layer interacts with the functional element such that the total solar energy transmittance through the composite pane in the darkened state is lower than in the bright state and/or the energy transmittance through the composite pane in the darkened state is lower than in the bright state.
