Abstract
Window consumes around 4% primary energy in developed countries. Thermochromic material responds to temperature passively which makes it attractive in the energy saving smart windows application. The most studied inorganic VO2 has the intrinsic problems of low luminous transmission (Tlum) and low solar modulation (ΔTsol the transmission difference between high and low temperatures). Our group have developed some new approaches to tackle this veritable challenge with more recent work on new radiation regulated smart windows, multifunctional smart windows and lab to fab transfer studies.
