The global Building Automation Systems (BAS) market is projected to nearly double in size from US $106.8 billion in 2025 to US $205.8 billion by 2032 as investment grows in smart buildings.

According to a report by Persistence Market Research, BAS building operators are increasingly using BAS to meet growing regulatory and client demand for lower carbon emissions and smarter energy use.

The report says a key trend underpinning growing demand for BAS is the shift from proprietary systems to wireless, open and interoperable protocols. This shift is unlocking greater flexibility and scalability, accelerating BAS adoption across both new developments and retrofit projects.

A transformative shift in building automation

From intelligent lighting and HVAC to access control and safety systems, modern BAS platforms help buildings operate more efficiently, respond in real time and meet evolving performance standards.

By moving away from closed, vendor-specific systems to open platforms like BACnet and KNX, building owners and operators gain the ability to integrate diverse technologies, streamline upgrades, and reduce long-term maintenance complexity.

Wireless deployment further increases adaptability, making BAS feasible in older buildings, temporary structures, or areas where traditional infrastructure upgrades are cost-prohibitive. These capabilities are expanding access to smart building technologies—and turning them into strategic assets.

Technologies powering the future of smart buildings

Demand for BAS is also being enabled by three key digital developments:

  • Cloud-based platforms: Allowing remote access and centralised management across multiple sites.
  • AI and machine learning: Enabling predictive maintenance, energy optimisation and occupant-centric comfort strategies.
  • Cybersecurity safeguards: Protecting increasingly connected systems from digital threats and ensuring operational resilience.

Enabling the transition to net zero

Persistence Market Research concludes that as buildings face growing expectations to be both high-performing and sustainable, BAS will become an indispensable to the real estate sector’s environmental strategies. By integrating BAS with renewable energy, daylighting controls, and smart technologies, building operators can reduce emissions, optimise performance – and improve occupant comfort.
