Building automation market seen hitting $230.72B by 2035

The global building automation system market is projected to more than double from $88.54 billion in 2025 to $230.72 billion by 2035, driven by stricter energy rules, falling hardware costs and rising demand for cloud-based controls. Europe and North America remain key demand centers, while Asia-Pacific is expected to grow fastest as code enforcement tightens.

Why it matters: - Building automation is shifting from a discretionary upgrade to a compliance requirement in many markets. - The market’s growth reflects stronger energy mandates, cheaper sensors and controllers, and new revenue from analytics and demand-response programs. - Vendors that can sell outcomes, not just hardware, are positioned to gain share as buildings become more connected and more regulated.

What happened: - The global building automation system market was valued at USD 88.54 billion in 2025. - The market is expected to reach USD 97.44 billion in 2026 and USD 230.72 billion by 2035. - That implies a 10.05% compound annual growth rate through 2035. - Market Research Future published the forecast and segmentation report on the building automation system market. - The report includes a sample copy at More information. - The full report is available at the company’s announcement.

The details: - The European Union’s recast Energy Performance of Buildings Directive requires non-residential buildings above 290 kW effective rated output to install building automation and control systems by the end of the decade. - The same directive lowers the threshold to 70 kW from 2030. - The U.S. Inflation Reduction Act’s Section 179D deduction offers up to USD 5.81 per square foot for qualifying efficiency retrofits. - Hardware accounted for 45.6% of 2025 revenue. - Software is forecast to grow at a 10.7% CAGR through 2035. - Services generated USD 21.87 billion in 2025. - HVAC control remained the largest system type with a 36.2% share in 2025. - Energy management systems are projected to grow at a 10.8% CAGR. - Commercial buildings made up 44.8% of 2025 spending. - Residential deployments are projected to grow at a 10.9% CAGR. - Wired communication held 59.9% of 2025 revenue, while wireless communication is growing at a 10.72% CAGR. - New-build projects accounted for 52.3% of 2025 revenue, while retrofit projects are projected to grow at a 10.47% CAGR. - North America held 32.3% of 2025 revenue. - Europe generated USD 24.61 billion in 2025 revenue. - Asia-Pacific is projected to grow at a 10.45% CAGR. - The market’s main growth drivers were listed as tighter building energy codes, lower sensor and edge-controller costs, cloud analytics and predictive maintenance, and utility demand-response payments. - Sensor bill-of-materials costs have fallen roughly 60% over the past decade. - The International Energy Agency estimates global investment in building energy efficiency reached about USD 270 billion in 2024. - Wireless sensor node costs have dropped below USD 12 per point in volume, versus roughly USD 90 for a hard-wired equivalent including labor. - Automated fault detection and diagnostics typically identifies 8% to 15% whole-building energy savings in first-year deployments. - U.S. demand-response programs enrolled roughly 33 GW of capacity by 2024. - Buildings with automated setpoint control can earn USD 40 to USD 90 per kW-year in constrained zones.

Between the lines: - The market is being pulled by regulation as much as by energy savings, which shortens buying cycles and raises urgency for building owners. - Falling hardware costs are expanding the addressable market to smaller portfolios that were previously too expensive to automate. - Software and services are gaining importance because they create recurring revenue after installation, while hardware is becoming more commoditized. - The report frames Europe as a compliance-led market and Asia-Pacific as a construction-led market, which means vendors may need different go-to-market strategies by region. - The rise of cloud analytics, autonomous optimization and operational-data monetization suggests the value chain is moving upward from devices to platforms.

What's next: - The report expects autonomous operations to replace scheduled control in large portfolios by the early 2030s. - It also expects supervisory software to consolidate around a smaller number of horizontal platforms with certified device ecosystems. - Heat pumps, on-site solar, batteries and EV charging are likely to push buildings toward bidirectional energy management. - More markets are expected to tighten code enforcement, especially in emerging economies. - Small-portfolio subscription models and hardware-as-a-service offerings are likely to keep expanding as zero-upfront financing gains traction.

The bottom line: - Building automation is moving from a building-efficiency add-on to core infrastructure for compliance, operations and grid participation.
