Difference between BMS and EMS
1. Building Management System (BMS) :
Building Management System (BMS), as name suggests, is a software management tool that is generally used to manage and helps one to take decision regarding all building decisions.
2. Energy Management System (EMS) :
Energy Management System (EMS), as name suggests, is a software management tool that is generally used to manage all energy used by assets and facilities within organization.
Difference between BMS and EMS :
BMS | EMS |
---|---|
BMS mainly focuses on Building management i.e. manage and control all mechanical and electrical equipment’s. | EMS mainly focuses on Energy management i.e. manage and control power supply to all assets, equipment’s, facilities, etc. |
BMS usually makes it more simply to control and manage building by simply automating some resources. | It does not provide any control or automation functionality. |
It makes sure that building or organization operate effectively i.e. operates in right way that helps one to complete task and achieve goal. | It provides all information to mangers to make them easily understand and makes best and effective use of energy or power system. |
It generally saves more energy as automation of system makes use of systems more effective. | It makes sure that building or organization operate efficiently i.e. operate in best possible manner without any waste of energy. |
BMS usually requires hardware to automate system control. | It does not require any hardware. |
It is more complicated and costly than EMS. | It is less complicated and costly than BMS. |
It does not provide any reporting or historical data. | It is basically a reporting and decision support software tool. |
It does not provide any insight information about how building system should be adjusted and why. | It provides insight information to team members about what is going on, how building system should be adjusted and why. |
It also provides security measures. | It does not provide any security measures. |
BMS is also known as macro level analysis. | EMS is also known as micro level analysis. |
One cannot identify and solve operational problems and issues related to energy usage. | One can identify and solve all operational problems and issues related to energy usage. |
