Limitations of a Building Management System - BMS Limitations

Limitations of a BMS system

With the flourishing excitement around the alternatives of tomorrow’s buildings, there is a confidence that “building management systems are the backbone of smart buildings.” There are severe limitations of BMS system data that can be captured by BMS. Thus, a restriction on the extent to which BMS data can facilitate the future envisioned for tomorrow’s buildings.

Limitations of BMS system

The reason behind the limitations of BMS system fails

Data is Expensive to Acquire & Utilise

In recent years, the cost of sensors has dropped precipitously. In 2004, the average cost per sensor was $1.30 and expected to be $0.38 in the year 2020. Unfortunately, the cost reductions in sensors have not resulted as per expectations of a full BMS installation. As of 2014, the cost to deploy a primary BMS was at least $2.50 per square foot and could be as high as $7.00 per square foot. While the price of sensors has plummeted, the cost of equipment controls has remained consistently high.

There May be Limited Value

The set of data is as good as the insights that can be derived. In the case of BMS data, ideas usually involve setpoints, equipment schedule and system configuration optimisations. Highly granular data sets around startup and shutdown processes may yield to optimisation insights for system configuration.

It’s Likely Missing the Small Equipment

  It has noted that schedules in office and multifamily buildings do get changed for maintenance purposes. This maintenance is a severe issue that can lead to massive spikes in operating costs and comfort in peril. As such, to ensure that operators are notified immediately, there should be smart building technologies in place.


  The final limitation of using BMS data to optimise a portfolio of buildings is the inherent lack of scalability. Each vendor is going to have its own proprietary data protocol, which requires a developing and maintaining several different integrations and processes. The BMS vendors often have competing products and thus are incentivised to make their data inaccessible to third parties.

Final Thoughts

The applicability of a BMS for its core functionality concludes to specific needs and goals of the property. However, to create a “smart” building that has fully optimised system, a BMS should not be relied upon to provide data and insights.

Security concerns

  BMS is an excellent conduit for the implementation of IoT technology, but there is still a way to go before we have smoothly functioning and completely dependable automated systems. Leading experts are consistently innovating to bridge the gap incompatibility between software and hardware components of IoT. These components further lead to leave plenty of potential entry points for attacks from cybercriminals, i.e., hackers.


  The drawbacks of cost, breadth, ongoing value and scalability of BMS data are not coherent with tomorrow’s buildings. The precise controls enable by BMS will likely have a role to play in smart buildings. Besides, a BMS should not be considered a requirement to achieve and maintain a top-performing structure.
