This study discusses the thermal insulation, power generation, and energy consumption analysis of solarpowered energy-saving glass (intelligent solar-powered energy-saving glass), using software simulations of its application in buildings. The study shows that, based on temperature data obtained from software simulations at the same point in a building using different glass materials, the internal temperature trend is as follows: Intelligent solar-powered energy-saving glass (opaque mode) < Intelligent solar-powered energy-saving glass (transparent mode) < Ordinary glass. Intelligent solar-powered energy-saving glass (opaque mode) features low thermal conductivity and low transmittance, preventing heat generated by sunlight from easily transferring to the indoor environment. Instead, the heat accumulates on the outer surface of the glass, thus preventing a significant rise in indoor temperature. In contrast, ordinary glass has high transmittance, allowing most radiant heat to easily enter the room, leading to higher indoor temperatures. Buildings with extensive glass installations do tend to have lower indoor temperatures. Furthermore, the opaque mode of intelligent solar-powered energy-saving glass can be effectively used to predict building energy consumption, achieving optimal energy savings.
