What is a Smart Building? Smart Buildings refer to digitally connected structures that use IoT technologies to monitor, analyze, and control building systems such as lighting, HVAC, security, and occupancy in real time. These systems aim to improve operational efficiency, reduce energy consumption, and enhance the comfort and experience of occupants. Within the broader IoT ecosystem, Smart Buildings function as a convergence point between physical infrastructure and digital intelligence. They integrate data from distributed sensors with centralized or edge-based platforms to enable automated decision-making and predictive optimization. This transformation turns buildings from static assets into dynamic, responsive environments. How Smart Buildings work The architecture of Smart Buildings is typically layered, combining hardware, connectivity, data processing, and application services. At the foundation are IoT devices that collect environmental and operational data. These devices communicate with gateways
