The market for building management systems was estimated to be worth 6.65 billion US dollars in 2016, and it is anticipated that it would reach 19.25 billion US dollars by the year 2023. In and of itself, this demonstrates not only how large the industry is already but also how much of a growing market it is expected to become in the future. The market for software solutions that give an analysis of the data that is being monitored and display it in a way that is simple and easy to comprehend is expanding at a rapid rate. The effectiveness of building monitoring systems is increasing in the market, and this is one of the reasons why they are becoming so popular. Building management systems provide building managers with the ability to regulate and change systems in order to maximize their performance, as well as provide them with the ability to understand how buildings are performing. Additionally, business management systems (BMS) can assist in the following areas: visualizing data, automatically generating reports, and creating alarms and alerts when parameters are exceeded, failures occur, or with prognostic systems, when failures are likely to occur. These capabilities are in addition to the fact that they allow for ease of control. It is also possible for them to enable comparisons between different places, buildings, and benchmark data. Intelligent building management systems are able to bring together information and controls that pertain to a variety of different systems that are running with a variety of different software programs. This enables the systems to be managed from a single interface. This not only makes monitoring and analysis easier to understand and more complete, but it also enables information from one system to have an impact on the controls for another system. Building management systems (BMS) have traditionally been associated with large commercial buildings. However, as equipment has become simpler to control, monitoring and detection has become less expensive, and wireless technology has become available, buildings of all sizes are having increasingly complex control systems installed. As an example, this may enable homeowners to connect to their residence and activate various equipment, including as the lights and the heating system, prior to their arrival. For further information, please refer to the internet of things and smart buildings. After all, the Internet of Things is a significant additional field that is connected to all of this as well. The integration of building monitoring systems with building information models (bim) is now possible. This integration makes it possible to compare the performance of the building in use with design requirements and design simulations. This has the ability to assist in the identification of possible issues in operation or design, as well as in the validation of modeling methodologies. As an additional possibility, building information models might include details about the functioning and maintenance of various building components. When it comes to the manner in which it operates, air conditioning is yet another domain that might be very much connected to this.
