Buildings that simultaneously provide natural illumination and thermal comfort for all seasons have met with increasing demand as conventional resource limitations are realized. In this context, organic and metal–dielectric coatings are tested, and a simple, coated double-glazed window with solar blinds is conceived that includes passive infrared (IR) reflection, active illumination control, and integration to the building envelope. As a result, a proper spectrally selective coating is applied to produce a low-emissivity solar window with climate-adaptive co-utilization of the reflected IR.
