Definition of Smart Buildings
Smart buildings are structures that use advanced technologies to collect and analyze data from various systems and sensors throughout the building. This data is then used to optimize the building’s operations and reduce energy consumption, resulting in significant cost savings for building owners & operators. For example, a smart building’s HVAC system can use sensors to detect certain areas that don’t require further cooling and adjust the temperature accordingly to save energy.
In addition to energy efficiency, smart buildings also offer enhanced occupant comfort. For instance, lighting systems can be automated to adjust brightness and color temperature based on the time of day or occupancy levels, creating a more comfortable and productive environment for occupants.
Smart buildings incorporate real-time equipment health and energy monitoring, which enables building owners and maintenance teams to gain valuable insights for proactive maintenance of the assets and equipment. This proactive approach leads to better returns on asset investments, lower maintenance costs, and fewer equipment failures.
Overall, smart buildings leverage a range of interconnected systems and technologies to optimize their operations, reduce energy consumption, enhance occupant experiences, and improve the overall sustainability and efficiency of the building.

iii) Controllers: Controllers are devices that manage and coordinate IoT devices and systems. Controllers can provide real-time monitoring and analysis of data, and can automate responses to equipment issues.
2. Connectivity
The connectivity aspect of IoT technology allows devices to either directly connect to the cloud (and hence have in-built IP communication such as Ethernet/WiFi/Cellular) or connect with an on-site gateway over wired (e.g. Modbus/BACnet) or wireless (e.g. Zigbee, OpenThread) protocols and the gateway then connects to the internet with its own IP communication.
Such connection allows the data which is captured by the sensors to be transmitted to the cloud for further computation & analytics. Similarly, instructions sent by the users or algorithms are transmitted from the cloud to the actuators/relays.
3. Cloud Computing and Analytics
Cloud computing and analytics are technologies that enable data analysis and storage in remote servers (i.e., “the cloud”). These technologies are important for smart buildings because they enable real-time monitoring and analysis of building data, allowing building operators to optimize building operations and improve occupant comfort.
Some examples of IoT-powered cloud computing and data analytics used in smart buildings include:
