Abstract
As identified by environmental scientists on energy consumption statistical projection, energy shortage is among one of the most prominent current global issues. Thus, energy saving solutions are becoming more and more relevant, since they are beneficial ecologically, financially, and personally. Therefore, there are more scientific research studies being conducted in increasing energy efficiency at a reduced rate in order to gain continuity of energy availability while lessening harmful negative environmental impacts (e.g., thermal pollution, glass house global warming effects). Working towards this crucial goal, this paper shares a new method of designing smart and efficient energy saving system using PDLC glass. It is capable of automatically turning into the user's shades of choice gradually from a remote control. This capability is dependent on the building's sun movement or sunlight exposure throughout the day from any angle of the building, which is detectable by a programmable Arduino light sensor. This is especially beneficial for areas with stable weather patterns and can also serve as a replacement for traditional curtains or blinds. When considering the initial cost of the product and the time spent installing and maintaining them, curtains or blinds cost more while only having similar results on decreasing or increasing the solar illumination, sunlight exposure, and temperature control according to the weather. An added benefit is that it can also turn the thermal pollution factor into a regenerative renewable storable solar energy by eliminating the sunlight reflection over the building when the glass absorbs it. Tests on the invented prototype validate its feasibility, offering an economical yet efficient option as a choice for smart energy saving systems.
