Building Automation Systems Market Segmentation:

Component Segment Analysis

The hardware segment, which includes controllers, sensors, and actuators, is anticipated to occupy a dominant 57% share of the building automation systems market during the forecast period. This leadership position is underpinned by the underlying nature of these elements to any BAS deployment and by continuous innovation in device technology. The strategic significance of the hardware marketplace is underscored by big-ticket transactions. In a high-profile deal, Honeywell announced in December 2023 to acquire Carrier's Global Access Solutions business for $4.95 billion in a transaction intended to strengthen its product offering in building automation and security hardware. This agreement highlights the ongoing mergers in the building automation market, with companies vying for a greater share of the important hardware segment.

System Type Segment Analysis

The access control and security segment in the building automation systems market is expected to capture a 52% share by 2035, driven by the growing need to protect physical assets and encourage occupant safety. Integrating security solutions into broader building automation platforms makes it possible to respond faster and more coordinated to potential threats. The market sees increased collaboration to develop these capabilities further. Hikvision and Can'nX signed a technology partnership in March 2024 to integrate its security solutions, such as facial recognition terminals and video intercoms, directly to the KNX protocol, enhancing building automation for commercial and residential buildings. This collaboration is a reflection of the trend towards comprehensive, intelligent security solutions that are central to building management in contemporary times.

Communication Technology Segment Analysis

 The wired communications technology market is forecast to hold a 63% market share through 2035, reflecting its persistent relevance in providing secure, low-latency connectivity for critical building systems. Even as wireless technologies gain popularity, the reliability and security of wired connections like Ethernet and purpose-specific protocols remain intrinsic to base BAS operation. New, high-performance Building Automation Systems (BAS) are being planned with a focus on network efficiency and reliability, favoring wired infrastructure. A prime example is the September 2024 release of Johnson Controls' Metasys 14.0, which features increased IP device capacity and improved network performance. This reliance on cabled systems ensures that building automation is resilient and cost-effective, capable of responding to the changing demands of modern infrastructure.
