Cost and inadequate electrochromic performance are the current technical challenges. Receive antennas for limited space with good noise rejection.Dual-band electrochromic smart windows with independent control of the transmittance of near-infrared (NIR) and visible (VIS) light can contribute significantly to the reduction of building energy consumption.
