Overview
Building Controls & Automation Hardware covers the sensors, thermostats, controllers, and building-automation devices that manage HVAC, lighting, and building systems. At ~$3B in device manufacturing it is led by building-controls majors (Honeywell, Johnson Controls, Siemens, Schneider Electric), though the broader building-automation systems-and-software market is far larger.
Demand is driven by energy management, smart-building and IoT adoption, decarbonization, and the integration of building systems onto connected platforms. It is consolidated at the device level and one of the most strategically important, high-growth corners of building equipment, with software and analytics increasingly the value driver.

Flat over five years, which is the hardware story rather than the market's: value has migrated from the controller to the software and analytics layer sitting above it, and the device itself is increasingly a commodity endpoint. The businesses that hold margin are the systems integrators specifying and servicing the estate, and those are classified as contractors rather than manufacturers.
