The way smart glass changes the way buildings use light, heat and privacy has already begun, but it’s just beginning to happen with the incorporation of artificial intelligence (AI), and the internet of things (IoT) in this product area. At its most basic level, smart glass provides users with the option to either make their window transparent or opaque, and/or to allow them to adjust the tinting of the glass. When smart glass is used with AI and IoT, the simple glass becomes a more complex, intelligent, self-adjusting building component.
In 2026, increasing energy costs, sustainable design goals, and a worldwide trend toward the creation of "smart" buildings will drive the need for data-driven and automated solutions to provide the high degree of automation required to meet the needs of both the occupants and the owners of these buildings. AI and IoT can make smart glass a responsive system capable of learning about the environment in which it operates, and adjusting itself accordingly to create comfort, efficiency, and optimal performance for the occupants of a building.
The purpose of this blog is to serve as information for architects, developers of real property, professionals working in the field of "smart" buildings, facility managers, and those interested in technology, who would like to learn how intelligent glass systems are creating new ways to design and build a wide variety of environments, and why companies such as Privetek are creating smart glass products that are ready to be integrated with artificial intelligence to address the needs of tomorrow's buildings.
Evolution of Smart Glass: From Manual Control to Intelligent Systems
Early smart glass systems used simple control methods, including wall-mounted buttons/switches, remote controls, or set timers. These systems allowed for on-demand privacy or shading; however, they were largely static and required human input.
There are several disadvantages to non-connected smart glass systems.
- No sensor information about current weather or occupancy levels
- High energy waste through constant (static) use of predetermined settings
- Scale limitations in large commercial spaces
The development of smart glass with an intelligence layer has been initiated by connecting smart glass to sensor systems, networks, and other building technologies. Today's AI and IoT-enabled smart glasses are based on data and are adaptable. The smart glass can operate automatically in response to both environmental factors and user behavior without requiring human intervention.
Role of IoT in Smart Glass Technology
Sensors Powering Smart Glass Decisions
IoT is the backbone of smart glass technology, which will allow smart glass to "know" what its surroundings are by using sensors. The most common sensors for smart glass are:
- Lux light sensors: Measuring daylight intensity to adjust glare and brightness
- Temperature and thermal sensors: To detect both internal and external heat levels
- Motion/occupancy sensors: To determine if a space has people occupying it
- Sensors for weather/environment: To measure sunlight, clouds, etc.
The above sensors provide real-time information so smart glass can react in a very precise manner.
Connectivity and Communication Protocols
Smart glass that is enabled by IoT depends upon a solid communications standard like Wi-Fi, Zigbee, Z-wave, BACnet and/or KNX. Each of these provides the smart glass a way to be integrated into other systems of a building.
Smart Glass Control Architectures can be composed of:
- Edge devices that are able to provide faster responses because they do the processing on the device itself, versus sending the request to a cloud.
- Cloud-based platforms that are used to provide a central point for analytics and optimizations.
The integration of smart glass with a Building Management System (BMS) allows the smart glass to work cooperatively with the HVAC, lighting and security systems in the building.
Real-Time Monitoring and Remote Control
IoT (Internet of Things) technology enables managers to access a central dashboard for viewing glass performance throughout an entire building. With this capability, users are able to manage smart glass using their mobile device, via a voice assistant, or by using an API that connects to a larger smart building ecosystem.
How AI Enhances Smart Glass Functionality
Predictive Light and Heat Management
AI does one better than just taking sensor data and creating an ability to identify patterns and make predictions for the future. Unlike reacting to changes in environmental conditions, smart glass that is driven by AI can adjust its tint level prior to changes in the environment.
The key features of smart glass with AI are:
- Learn about the preferences of occupants, from experience and history
- Predict sunlight based upon seasonal patterns and the time of day
- Adjust for optimal daylight automatically – no user input required
Energy Optimization Through Machine Learning
Smart glass can be paired with HVAC and lighting systems through machine learning algorithms. Smart glass balances artificial light, heating gain and cooling demand through the use of AI to continually improve a building's energy efficiency by reducing peak energy loads.
The system will become smarter over time, identifying inefficiencies in the system and continually refining strategies that help achieve the greatest amount of energy savings.
Computer Vision and Context Awareness
Smart Glass with Privacy Safe Computer Vision Technology Can Use Privacy-Safe Artificial Intelligence (AI) to Understand Space Usage. Smart Glass does not store identifiable personal data for this purpose. The technology is able to:
- Determine the level of occupancy
- Automatically adjust the level of privacy, depending upon what is occurring in the room
- Determine common usage patterns in a Meeting Room, Ward, or Living Area.
AI + IoT Use Cases for Smart Glass
Smart Offices and Commercial Buildings
Smart offices and commercial buildings are among the most popular applications of AI-based smart glass. Smart glass can help increase office worker productivity through a variety of ways, such as minimizing glare, maintaining the right amount of daylight, and instantly changing privacy levels during a meeting. With the automated functionality of smart glass, an office worker can enjoy a workspace that is always comfortable and free of distractions.
