Smart buildings are integration-heavy systems.
A single facility can include HVAC units, CRAC systems, lighting controllers, elevators, escalators, meters, access control systems, occupancy sensors, PLCs, gateways, local controllers, vendor APIs, and building management software.
Each subsystem may work well on its own. The real engineering challenge is making them work together.
For developers and system integrators, smart building automation is not only about connecting devices. It is about building a reusable architecture for data modeling, event processing, monitoring, control, dashboards, alerts, and workflow integration.
Platforms such as Iotellect show how different building systems can be unified through one low-code IoT/IIoT architecture instead of many disconnected dashboards.
