Thermochromic Glazing For "Zero Net Energy" House

Thermochromic laminated glazing (TLG) enables to regulate daylight automatically adapting dynamically to the continuously changing climatic conditions, aids in reducing the energy needs of a building and providing thermal comfort. Nether electrical power nor driving unit are required. The polymeric interlayer of TLG is doped with complexes of transition metals, which change their coordination and transmission or colour of the film under influence of light and heat fluxes. Now we have neutral colour conversions from light to dark (grey or brown) and coloured ones from rosy for yellow to blue and green at our disposal. In combination with Low-E glass, TLG makes possible to create regulated cover heating for "zero net energy" houses.
