Building Management System


What is a Building Management System (BMS)?


Building Management System is a computer based central control system that is installed in buildings in order to control and monitor both mechanical and electrical equipment. BMS systems enable management of utilities such as air conditioning, ventilation, power systems and lighting, as well as security and fire-fighting systems. A Building Management System has three basic functions: Controlling, Optimizing and Monitoring.

Example functions of BMS include temperature and humidity control, measurement and control of electrical parameters such as voltage, monitoring and control of various water pumps, switching on/off of compound light based on outside light level, etc.

  • The BMS solution ensures that lighting is turned on/off in conference and meeting rooms, cabins, server rooms, and walkways automatically when the area is occupied/unoccupied using motion sensors. Further, the electric lighting systems can be designed to be dimmed with the availability of daylight. Up to 75% of lighting energy consumption can be saved.
  • BMS solution optimizes electricity usage of the air conditioning system by controlling temperature, fan speed, mode etc. based on occupancy. It can raise an alarm if the external doors are left open for a long time resulting in loss of efficiency. It can also operate curtains based on the configuration or temperature sensor input to improve efficiency.
  • BMS can alert you about any unexpected activity detected. Alerts are sent by sending email, text message (SMS), and by making phone calls. It can also take appropriate actions on occurrence of emergency conditions by turning on the sprinkler system in case of fire detection and turning on the hooter to alert security agency if it detects suspicious activity in restricted area. Most of the devices in the BMS solution utilize wireless communication to ensure that the deployment is quick and hassle free.



Why do MSMEs need BMS?


Earlier associated with large corporates, building management systems integration is increasingly being considered by small and medium enterprises. The integration invariably brings the management of various components of building management - heating, lighting, lifts, air conditioning, power distribution, security measures and fire detection into one system.

Building Management System (BMS) is meant for saving energy and maintenance costs. Until recent years, energy efficiency has been a relatively low priority to building owners. However, with increase in awareness of energy saving, and advances in cost-effective technologies, energy efficiency is fast becoming part of real estate management, facilities management and operations strategy.

BMS can curtail the energy expenditure of an organization and result in optimal utilization of energy. For lighting, energy savings can be up to 75% of the original circuit load, which represents 5% of the total energy consumption of the residential and commercial sectors. Energy savings potential from water heating, cooling, or hot water production can be up to 10%, which represents up to 7% of the total energy consumption of the domestic residential and commercial sectors. Thus, BMS solution can reduce the energy expenditure of an organization by 15 to 20%.

BMS Providers: Global automation majors such as Honeywell, Siemens, ABB, a host of South-East Asia based companies, as well as Indian MNCs/companies such as L&T are in the BMS business. However, in order to implement BMS in their buildings, SMEs may even contact local electrical contractors and system integrators who provide efficient low-cost solutions tailor-made for such enterprises.



Are there any Incentives for Implementing BMS?


Government Initiatives around the world are driving the development and adoption of Building Management Systems technologies. In India too, there are various schemes that promote implementation of BMS in the organization premises. The Bureau of Energy Efficiency’s (BEE) ‘Energy Conservation Building Code’ or ‘Start Rating Program’ is an important scheme promoting energy efficiency among buildings in India.

Energy Conservation Building Code (Star Ratings Program)

BEE has introduced various schemes related to providing ‘Star Ratings’ to commercial buildings of BPOs, office buildings, schools, healthcare facilities and hotels. Star ratings program will involve rating by computing the performance of energy efficiency in buildings on a scale of one to five with five star labeled buildings being the most energy efficient.
