With electricity costs constantly increasing, Italian families are looking for ways to save and reduce their dependence on the public distribution system. Among these, building-integrated photovoltaics is gaining popularity due to its numerous innovative applications. An example of technological excellence is the smart solar windowa cutting-edge system developed by Hunan University, capable of producing renewable energy and improving living comfort.
Innovative composition of the solar window
This smart window stands out for its highly technological structure, consisting of:
Thanks to this combination, the window not only generates energy but also offers protection from the sun, ensuring significant energy savings.
The heart of the window is his electrochromic filmcomposed of multiple layers that interact with the applied voltage. In the absence of tension, the film remains transparent; when a voltage is applied, the lithium ions they move towards the electrochromic part, changing its color and blocking part of the heat and sunlight. The dark shade increases with voltage intensity, providing customized thermal and light control.
Through simulations with the software EnergyPlusresearchers compared the performance of smart windows with traditional Low-E windows in different climate contexts (Fuzhou, Xiamen, Hong Kong and Haikou). The results highlight:
This innovation not only promises energy savings but also represents a step forward towards more sustainable construction.
