Today?s building automation system (BAS) consists of control devices with embedded computing and digital communications tools that enable automated system improvements for operational efficiency, occupant comfort, and improvements in energy efficiency. Commercial BASs control functions of heating, ventilation, and air conditioning (HVAC), lighting, fire And life safety, and security And access controls. Building management systems (BMSs) assimilate these products into an integrated control network. The opportunity to optimize energy consumption has been the foundation of BAS market demand as customers aim to comply with building codes, save on utility costs, and meet sustainability objectives. The development of the intelligent buildings market has introduced customers to new tools for data acquisition and analysis and services that enable more holistic business improvement opportunities. Early adopters are investing in intelligent building solutions that can compete with traditional BAS offerings by providing broader analytics. Turnkey intelligent building solutions offer hardware, software, and services to maximize energy efficiency alongside other business benefits. Major BAS vendors recognize the market evolution and are introducing new versions of their core BAS offerings as well as complementary intelligent building solutions. The result is an increasingly dynamic competitive landscape of diverse offerings. According to Navigant Research, global commercial building automation product and services revenue is expected to grow from $67.1 billion in 2016 to $102.0 billion in 2025. This Navigant Research report analyzes the global market for commercial BASs in five key technology segments: HVAC, lighting, fire And life safety, security And access controls, and BMSs.
