What is a Building Management System (BMS)?     

The BMSs’ core function is to manage the internal environmental conditions within a building, i.e., temperature, in a way that is as energy-efficient as possible.

A Building Management System (BMS) is a computer-based system installed in buildings to control and monitor mechanical and electrical plants, including HVAC (heating, ventilation, air conditioning), lighting, power systems, fire systems, and security systems.

Effective well-utilized Building Management Systems (BMS) provide the core management tool required by building managers to ensure monitoring and efficient management of energy and occupant comfort. It enables Building Managers to provide the optimal working environment while minimizing the cost. Effective BMS utilization allows for optimal building performance by extending equipment and systems' operational life by reducing loads and operating hours. Therefore, maintenance and capital costs are reduced, and less embedded energy is consumed through equipment replacement and upgrades.

BMS will show increases in energy use due to equipment failure or adjustments to operating parameters. For example, heating valves open when the building requires cooling. BMS may also indicate that air-conditioning is starting up hours before the building is fully occupied due to security staff activities. With this information in hand, the Engineering manager may rectify such issues through consultation or engineering solutions.

In the absence of a BMS, the impact of such events can be disguised by seasonal variations, changes in occupancy levels, or technology upgrades. A correctly configured BMS with an adequate number of precisely located monitoring points is the only way a building manager can quickly alert problems that could otherwise remain undetected until annual inspections or external audits are undertaken.

A BMS is also a primary tool for identifying energy intensity improvement opportunities, for example, refining the size and number of lighting time blocks, providing meaningful reports to the Environment of Care Committee on issues and opportunities, and enabling identification of faults, maintenance planning, and energy-saving upgrades.

What is a Smart Building?

A Smart Building is one in which the essential equipment and assets, like air handlers, chillers, boilers, lighting, etc. can communicate machine-to-machine. There’s an elaborate management system in place to control and optimize all the pieces.

A Smart Building aims to deliver useful services that help make occupants more productive and safer, at the lowest cost and with the least environmental impact. A Smart Building optimizes and minimizes energy usage and can operate using clean energy sources. It makes occupant security and quality of life top priorities. These priorities mean not only physical safety, such as connected fire suppression and alarm systems, but also health security— high-quality air and water, and more.

The equipment and systems in a Smart Building need to be connected and able to communicate from machine to machine. For example, a building’s chiller could receive weather data from outside and occupancy information from inside, so it operates only when needed to maintain its occupants’ optimal temperature.

What makes all this work? The availability of small, sophisticated, affordable sensors connected via the building automation software analyzes and uses the data generated by these sensors to manage and optimize operations. Smart Building systems can use the data generated to monitor performance, track the physical location of assets, detect potential operating issues, and improve preventive maintenance efforts.

Buildings today are complex concatenations of structures, systems, and technology. Over time, each of the components inside a building has been developed and improved, allowing us to select lighting, security, heating, ventilation, and air conditioning systems independently. Today, we seek to build, work, and live-in smart buildings as the right thing to do.  Many governments and industry regulators set standards for constructing and managing facilities to meet environmental, safety, and sustainability requirements.  LEED Leadership in Energy and Design Engineering is a certification program adopted by building owners and managers to certify their intent to comply with government and self-driven requirements.

Smart Buildings, which are one of the eight Smart principles behind Smart Cities, are expected to make up 7% of the total global smart city market in 2025. Smart Cities, cities that monitor all critical infrastructure conditions, including bridges, streets, water, electric systems, and more, are on the rise, as well. Frost & Sullivan estimates that by 2025, there will be more than 26 of them worldwide.
