Smart building market seen reaching $643.1B by 2035

The global smart building market is projected to grow from $149.2 billion in 2025 to $643.1 billion by 2035, driven by net-zero mandates, IoT sensors and AI-powered automation. The report points to rising retrofit demand, stronger energy regulations and growing interest in occupant experience and grid-responsive buildings.

Why it matters: - Smart building systems are moving from nice-to-have upgrades to core infrastructure for commercial real estate, healthcare, education and government facilities. - The market’s growth reflects pressure to cut operating costs, meet carbon targets and modernize aging buildings before they become obsolete. - Market Research Future projects the market will expand from $149.20 billion in 2025 to $643.10 billion by 2035, a 15.60% compound annual growth rate. - More than $2.4 trillion in global building infrastructure spending is expected through 2035, increasing demand for retrofit and new-build digital systems.

What happened: - The global smart building market reached an estimated $149.20 billion in 2025 and is forecast to rise to $174.40 billion in 2026. - The report covers solutions and services across wired and wireless connectivity and multiple building lifecycle stages. - Get the full report sample includes the full table of contents, tables and figures.

The details: - Legacy building management systems based on siloed proprietary protocols are being replaced by open, cloud-native platforms. - These platforms combine HVAC optimization, predictive maintenance, occupancy analytics, access control and energy monitoring into unified digital twins. - A JLL Future of Work survey found top-quartile enterprise occupiers using AI-powered smart building platforms achieved 22% to 30% lower energy use, plus gains in occupant satisfaction and productivity. - The market’s historical rise from about $72.6 billion in 2021 to $149.20 billion in 2025 shows sustained adoption across sectors. - Demand is being fueled by ESG mandates, municipal energy codes, post-pandemic workplace changes and lower costs for IoT sensors, edge hardware and cloud connectivity. - Buyers include commercial real estate developers, healthcare systems, educational institutions, industrial operators and government agencies.

Between the lines: - The report frames smart buildings as a structural shift in how buildings are designed, operated and monetized, not just a technology add-on. - AI and digital twins are becoming the main value drivers because they let operators predict failures, test retrofits and manage assets in near real time. - Occupant experience is now a competitive factor, with demand for personalized comfort, lighting control, mobile access, wayfinding and desk booking. - Decarbonization is expanding the business case beyond cost savings to include certifications, grid interaction and revenue from demand-response programs. - Competition is intensifying as vendors add generative AI, cybersecurity features and enterprise software integrations. - Key players listed in the report include Siemens AG, Honeywell International, Johnson Controls International, Schneider Electric, IBM Corporation, ABB Ltd, Cisco Systems, Microsoft Corporation, Bosch Building Technologies and Legrand.

What's next: - Smart building platforms are expected to deepen integration with ERP, HR and workplace management systems. - Wireless sensor networks should continue to spread as costs fall, enabling room-level monitoring for temperature, CO2, occupancy, light and vibration. - Zero-trust security and secure device onboarding are becoming standard expectations as operational technology connects more directly to IP networks. - Buildings tied to solar, storage and utility demand-response systems are likely to become more common as grid-interactive models gain traction. - Regional growth is expected to remain strongest in North America and Europe, while the Middle East and Africa is projected to post the fastest CAGR at 13.1% through 2035. - Read the full market report for segmentation, regional analysis and forecast details.
