In recent years, so-called "smart windows" have been gaining increasing popularity in the construction market. These innovative structures, thanks to built-in technologies, possess a range of useful functions. Let's delve into what makes these windows so attractive and why they might become a must-have for modern homes and apartments.
What Are Smart Windows
Smart windows are constructions with built-in automation, sensors, and control mechanisms that allow the windows to perform useful functions, enhancing comfort and security.
Features of the Design
Unlike traditional windows, smart ones are equipped with electric drives that automatically open and close the sashes. For instance, drives produced by Belimo allow for precise positioning of the sash at the desired angle.
Also, various sensors - for light, temperature, humidity, presence, and motion - are installed in the design. They detect microclimate parameters inside and outside the room and send the data to the central control unit.
For protection against overheating in summer, built-in blinds within the glass unit are used. They can automatically lower on hot days to prevent excessive light and heat from the sun.
Built-in Technologies
The core of smart window control is the microcontroller - a small computer that processes sensor data and sends commands to the actuators.
For example, the Reynaers Aluminium controller analyzes the room's temperature and, if it deviates from the set range, signals to open or close the sash.
Many smart windows support Wi-Fi and Bluetooth, allowing remote control via a smartphone. Apps like SimonsVoss, SecuSignal, and WindowMaster provide such capabilities for various window models.
The system can also integrate with other smart devices in the house via the KNX/EIB protocol and operate as part of a unified automated ecosystem.
Advantages of Smart Windows
Let's turn to the main advantages of smart windows.
Energy Efficiency
Thanks to automation, such windows save electricity for air conditioning and heating. Sensors monitor the indoor temperature and regulate it, allowing the right amount of heat and coolness.
Safety
Protection systems and motion sensors enhance home security, promptly alerting owners about suspicious activity near the window and automatically locking it during break-in attempts.
Comfort
Automation allows for maintaining a comfortable microclimate and lighting in the room. For example, blinds automatically lower on a hot day, blocking excessive sunlight.
Disadvantages and Complexities
However, smart windows have their downsides.
High Cost
Due to their electronics-rich and additional systems, such constructions are significantly more expensive than regular windows.
Need for Maintenance
Like any technology, smart windows require periodic inspection, diagnostics, replacement of parts, and software updates for proper functioning.
Future Developments
What trends are emerging in the development of smart windows?
New Technologies
Leading manufacturers are actively working on expanding the functionality of smart windows. One promising direction is the integration of voice control systems. For instance, Velux has developed window models compatible with Amazon Alexa and Google Assistant. Just give a voice command, and the window will automatically open/close thanks to the Velux Active drive.
Another interesting development is notifications about events to the owner's phone. For example, VELUX INTEGRA technology allows receiving push notifications about sudden changes in temperature or humidity in the room, window openings, and other important events.
Electrochromic glasses are also being actively improved. Kinestral Technologies has released a revolutionary product - Halio electrochromic glasses, capable of changing light transmission from transparent to opaque. This allows precise control of lighting and heat gain through the window, making it even more "intelligent."
Cost Reduction
As popularity grows and mass production increases, the price of smart windows will gradually decrease, making them more accessible to a broader range of consumers.
Conclusion
Smart windows are a technological solution that saves energy resources and creates additional comfort for homeowners. Despite their still high price, as the market develops, such constructions will become an increasingly attractive choice for consumers. A rise in demand for smart windows in the coming years can confidently be predicted.
