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 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.|
