Under rapid economic growth, Green house effect is deteriorating with increasing energy consumption. This had drawn the attention from world wide and various methods had been carried out for curing the evil. Accordingly, government may focus on campaigns for reducing consumptions, billing congestion charges to decrease car usage and encourage citizens setting A/C at a higher degree; and all those are green things to decrease carbon dioxide formed. However, on the other hand, what can we contribute to stop green house effect worsen as well as payless on electricity bills?

Since governments and communities are working on cut down energy wasted; we individuals can also be a savvier from changing household appliances. For example, peel off your old window films and stick on the Smart Film. In order to compare Smart film with normal window film, let us start on optical spectrum. With a simple switch, windows with smart film can transform in between clear/ white opaque; this isolates heat from sunlight (as shown in the diagram). When heat energy from visible light and infrared rays is isolated, power consumption of A/C is saved as well as our money.

To sum up, Smart film is not only easily installed on existing decoration but energy saving as well as protecting privacy without losing visibility.
