Energy Management Systems:
A scheme for providing a real time data acquisition and energy management system was initiated in early 1994. The scheme is being carried out through indigenous efforts, using the hardware and software in distributed architecture and based on the concept of open system and connectivity.
Cleaner production is gaining its reputation. Companies can easily have a good chance of availing certain regional and state grants. With a complete analysis of energy and emissions, a company can now take control of all sources and the source of carbon emissions.
Creative, effective ways to manage our energy consumption are critical in keeping up with demand, while avoiding skyrocketing emissions.”
It is a technique that uses energy information as a basis to eliminate waste, reduce and control current level of energy use and improve the existing operating procedures.
It builds on the principle “you can’t manage what you don’t measure”.
* Monitoring–It is aimed at establishing the existing pattern of energy consumption .
* Targeting– It is the identification of energy consumption level which is desirable as a management goal to work towards energy conservation.
The essential elements of M&T system are:
Recording - Measuring and recording energy consumption
Analysing – Correlating energy consumption to a measured output, such as production quantity
Comparing – Comparing energy consumption to an appropriate standard or benchmark
Setting Targets - Setting targets to reduce or control energy consumption
Monitoring - Comparing energy consumption to the set target on a regular basis
Reporting – Reporting the results including any variances from the targets which have been set
Controlling – Implementing management measures to correct any variances, which may have occurred.

Energy savings using BMS:

• Responsive control strategies:
• Resets on external and internal loads
• Demand-Control Ventilation
• Optimum start-stop
• Occupancy-interface to lighting controls, etc.( Room automation)
• Tenant Overrides

• Reduced Downtime:

• Remote Access (Dial-up, Web Server)
• 24 hour alarming, Back up

Preventative / Anticipatory Maintenance
• Continuous Implementation
• Run time Logging Vs Sensor Limits
• Fault Detection Diagnostics
• Automated Functional Testing

Energy Efficiency
• Rising Utility Costs
• 24/7 Monitoring
• Fresh air rates
• Lighting Control
• Utility Monitoring
• Service Monitoring  (Visitor management, Parking management, Security, Safety)
