Building Automation System Market Challenges:

Integration with Legacy Systems

The other significant integration challenge is with modern building automation systems, where old legacy infrastructures are integrated. Most old buildings are built with technologies that are decades old and do not support advanced automation solutions. Many such legacy systems do not implement the protocols or standards of communication, which makes integration a pain point during implementation. Upgrades or replacement require high costs, longer project durations, and disruption of operations. Further, some custom integration solutions are required, and it only adds more complexity and cost in modernization efforts. Moreover, building owners can face problems finding professionals who know the legacy systems and understand modern systems in detail so they can integrate them properly. Without proper planning, such projects can lead to inefficiencies or partial automation, undermining the benefits of BAS.

Cybersecurity Risks

As BAS has become highly dependent on IoT devices, cloud computing, and wireless connectivity, cybersecurity risks have started to emerge as a significant issue. BAS can be manipulated through unauthorized access to data breaches, operational disruptions, or even direct physical threats to human safety and property. For example, attackers may use vulnerabilities to take over control of HVAC systems, lighting, and security mechanisms, thus causing a risk of financial loss or safety. Most existing BAS implementations do not have proper security protocols, and thus they are vulnerable to attacks. Ensuring the security of such systems involves deploying end-to-end encryption, employing secure authentication methods, consistently updating software, and actively monitoring for potential threats. However, all these measures increase the complexity and cost of deploying and maintaining a system, especially in smaller buildings with limited budgets.
