Leviton Building Management Energy Management and Automation System

The BMS is a “stand alone” computer system that can calculate the pre-set requirements of the building and control the connected plant to meet those needs. Its inputs, such as temperature sensors and outputs, such as on/off signals are connected into outstations around the building. Programmes within these outstations use this information to decide the necessary level of applied control. The outstations are linked together and information can be passed from one to another. In addition a modem is also connected to the system to allow remote access.

Why do you need a Building Management System?

Integrated BMS system aims to establish a building in the form of a flexible control system. BMS integration, coordination and support system, linking the separate systems into a custom control system versatility. Common interface of the system allows the operator to observe the whole state and system control from a computer station, making our buildings operate more efficiently with lower costs while improving the performance rate of operation and building management.

In addition, the BMS system to help investors achieve greater efficiency with minimum effort. A challenge for the modern building management is how to remain active to ensure the increasingly rich and complex than in a building with a human quality is maintained at some small but elite? How to operate well in a team and operate when demand is increasing? BMS is a comprehensive solution and to overcome these challenges, the building manager will build an operating environment with efficient operational cost savings very much.

One reason it is also important means of investment BMS assigned responsibility for managing the entire system for a single department, which leveraged the power of centralized management model. An integrated system can experience connection of different systems, as one of the design, installation and adjustment operation to hand over to customers. Centralized management and a set of contacts will bring greater benefits when the problem occurred. Centralized management means managing the three major factors: efficiency, cost and productivity.

For these reasons, BMS has and will become inevitable tendency to choose the owner to bring the highest benefit, the most economical and more convenient for their buildings.

A BMS normally comprises:

• Lighting control system
• Electric power control system
• Heating,Ventilation and Air-conditioning HVAC System
• Security and observation system
• Magnetic card and access system
• Fire alarm system
• Lifts, elevators etc.
• Plumbing system
• Burglar alarms, CCTV
• Trace Heating
• Other engineering systems
• Fire alarm and Safety system

Functions of Building Management 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.
