The Advantages of Open Protocol Solutions in the World of Building Automation


The world of building automation is continually evolving, with the integration of advanced technologies changing the way buildings are managed and controlled. As a result, building owners, facility managers, and engineers are constantly seeking more advanced, flexible, and cost-effective control solutions. In this blog post, we will explore the advantages of programmable building controls such as BACnet, in comparison to traditional controls and proprietary controls like Tekmar, with a particular focus on Reliable Controls controllers.

Flexibility and Interoperability

One of the most significant advantages of programmable building controls, like BACnet, is their inherent flexibility and interoperability. As an open protocol, BACnet allows for seamless communication between different devices, regardless of the manufacturer. This eliminates the need for proprietary control systems that often lead to vendor lock-in, a major disadvantage in the world of direct digital controls (DDC). Open protocol solutions like BACnet offer a future-proof choice that can adapt to ever-changing building requirements and technology advancements.

Scalability and Expandability

Scalability is another critical aspect of building automation. As buildings grow, change, and evolve, so too should their control systems. BACnet-based controls are inherently scalable, meaning they can easily accommodate expansion and modification. Proprietary systems, on the other hand, often lack this level of flexibility, leading to increased costs and complexity when expansion or modification is necessary.

Lower Costs and Ease of Learning

While BACnet allows equipment from different vendors to communicate, programming is usually proprietary. Many vendors have high costs and a steep learning curve associated with their programming tools. Reliable Controls, on the other hand, offers an easy-to-learn platform without the need to pay annual fees for software usage. This makes it an attractive option for building owners and facility managers looking to reduce costs and avoid long-term commitments to a single vendor.


In summary, programmable building controls, such as BACnet, offer numerous advantages over traditional and proprietary controls like Tekmar. The flexibility, interoperability, scalability, and ease of integration offered by open protocol solutions like BACnet make them an attractive choice for building owners and facility managers. Moreover, Reliable Controls controllers stand out as an excellent option due to their user-friendly nature, the absence of annual software usage fees, and the avoidance of vendor lock-in. By embracing these advanced control systems, building owners and facility managers can enjoy increased adaptability and lower costs.
