Future Facility Management (FM)
Predict the trend for further
corrective and preventive action
Monitoring and analysing the
performance of the system
through visualisation from BMS
Extract equipment information/data
through cloud by scanning QR code
Receive pop-up Fault Signal through
Email or mobile devices
Use mobile phone/ tablet for report the
status of equipment/ control the
equipment
