The global market for the Building Internet of Things (BIoT) in commercial buildings is projected to expand from $64.1 billion in 2024 to $101.0 billion in 2030, representing a CAGR of 7.87% over the forecast period under the baseline scenario, according to our latest research. These new forecasts demonstrate the resilience of BIoT development in a turbulent economic environment. Our analysis adopts a five-tiered supply chain model that captures the major domains of value creation and technology delivery. Each tier represents a functional domain within the broader BIoT ecosystem, but all five contribute to the effective operation of smart buildings. This tiered framework provides a consistent lens through which we segment the BIoT market, evaluate vendor strategies, and analyze platform capabilities: Tier 1 – Traditional BAS includes rule-based automation systems for HVAC, lighting, and energy management, some using closed, vendor-specific protocols. Note that the Traditional BAS tier is NOT included in our market sizing figures. […]
