Houses can have a “greenhouse” effect. Light passes through, and strikes something. It is absorbed and turned to heat. The object then radiates that as infrared. Thermally shielded windows then trap this in the room. With enough insulation, and enough light, this can become a significant issue.
This is assuming, however, that these bricks are transparent to visible light, but opaque to IR.
