Energy saving performance analysis for solar-control films on single window glass

Analyses the energy saving principle of sticking solar-control films on single window glass. Compares the thermal performance between single window glass with and without the solar-control film. Experimentally tests the energy consumption of the central air conditioning system and the indoor daylight illumination in two hotel guest rooms with and without the solar-control film on the single window glass, and the result indicates that the energy consumed can be reduced by sticking the solar-control film on the single window glass. The theoretical and experimental results have a good agreement in the energy saved by solar-control films.
