How can windows improve insulation performance?

The proposed technology significantly improves insulation performance, ideal for cold climates. Windows contribute significantly to heat loss in buildings, making them a critical focus for energy-saving measures aimed at reducing the substantial energy consumption in the building sector.

Does optimized material improve insulation performance in energy-efficient windows?

Optimized material overcomes NIR transmittance and emissivity limitations of traditional low-e coatings. The study provides a universal methodology for material selection in energy-efficient windows. The proposed technology significantly improves insulation performance, ideal for cold climates.

Is soda-lime glass a high thermal emittance material?

First, conventional glazing materials with high transmittance, such as soda-lime glass, inherently have high thermal emittance (∼0.84), which leads to significant energy losses . High thermal emittance means that a large portion of indoor heat escapes through the glass, contributing to higher heating energy requirements.

What spectral characteristics are needed for achieving passive insulation?

The spectral characteristics necessary for achieving passive insulation were analyzed, emphasizing the need for high visible and NIR transmittance coupled with low MIR emissivity. Based on spectral matching design principles, high-mobility IHO films were prepared, with a mobility of 100 cm 2 /V·s and a carrier concentration of 2.2 × 10 20 cm −3.
