The building management system (BMS) is an overall control component responsible for the fully automated regulation and control of non-GMP facility subsystems, retaining predefined parameters (or set points) and the control of their features and functions. The main goal of the BMS is to ensure that the facility is operated safely. It also monitors and improves the use and performance of the supervised subsystems to enable more effective operation.
A building management system is a computer-based system that is installed in buildings to manage and monitor equipment like HVAC, lighting, power systems, security devices, IoT sensors, and gas and energy metres. Servers, supervisory devices, field buses, controllers, inputs, and outputs make up a traditional BMS. Building automation systems (BAS) is another name for building management systems.
A BMS integrates the HVAC and various building components so they can operate as a single, integrated unit. They should, ideally, centralise processes and improve data visualisation through a user interface or console.
Although there are additional uses for building management systems, controlling the HVAC, heating, and ventilation systems is typically one of them. The following are the primary elements of a building management system and their fundamental features:
- Maintain a consistent temperature and turn on and off boilers at predetermined intervals using boiler controls.
- HVAC: control fans, dampers, air handling devices, and fan coil units to maintain a specific air state in terms of temperature and humidity.
- Control the lighting to switch on and off the lights at specific times.
- Electric power control—manage and observe the main mechanical and electrical apparatus.
- Heating: schedule system on/off; keep a predetermined temperature.
- Adjust ventilation according to occupancy controls.
- Access control, monitoring, and intrusion detection are components of security and observation.
- Smoke control system, active alarm sites, and fire alarm system.
- Elevators: status system; elevator video display.
- Plumbing and water monitoring: detect hydraulic flows; automatically open/close valves; track/observe temperature variations.
BENEFITS OF BUILDING MANAGEMENT SYSTEM
- Lowering operational costs through system-wide energy optimization
Controlling sunlight transmission into rooms with blinds and shutters integrated into the building management strategy to reduce heating and cooling expenditures. Also includes integration of submetering and examination of a building’s energy profile to assess potential for optimization.
- Lowering maintenance costs to reduce operational costs
Service time is reduced by using automatic checks for lamp failures rather than manual checks. It includes monitoring the life cycle of a component to allow for replacement in advance and control solutions made with low-recurring maintenance costs in mind.
- Higher worker productivity results in a decrease in service costs.
Reduction of training and service staff by combining data from lighting, HVAC, and fire systems into a single common supervisor with a unified operational philosophy. And by allowing for mobile installation management via a tablet or smartphone.
- Safety of Building Tenant
When a fire is detected, shutters that open automatically allow firemen easier access to the building and create alternative escape routes. Before entering the area, a viable fire-fighting strategy can be determined by directing CCTV cameras in the direction of the fire detector. Escalators and elevators are being watched, and in the event of a fire, they are automatically switching to evacuation mode.
- Security of Building Tenants
The BMS’s integration of video surveillance systems makes it simple for a central supervisor to oversee small to large sites.
- Investing security
Integration of legacy systems to enable “smooth” updates of installed systems to new IoT technologies.
System architecture that is open and extendable and supports both standard and proprietary protocols from different manufacturers as well as customer-specific modifications.
- Extending the lifetime of plants and equipment
Early misconfiguration detection (e.g., oscillating actuators). Automatic performance deterioration monitoring (e.g., by monitoring the energy input vs. output).
APPLICATIONS OF BUILDING MANAGEMENT SYSTEM
- Distributing charges among tenants and keeping an eye on access control for unauthorised building use.
- Transferring lighting schedules between locations and remotely checking the on/off status of lighting based on room occupancy.
- Establish the proper order for equipment startup so that a facility can reach the desired temperature levels before people arrive.
- Real – time remote of equipment from outside the facility while necessary.
