21.5             Building Energy Management System (BEMS)


The Building Energy Management System is an analysis tool producing charts and reports to evaluate energy usage in buildings, campuses and other facilities.

This Building Energy Management System (BEMS) Software runs in association with WebAccess HMI & SCADA software. This is a software product requiring users to install appropriate energy monitoring hardware (such as electric kilowatt-hour meters, gas flow meters , etc) that can be connected to IO or automation hardware.  These sensors are then read by the WebAccess HMI & SCADA software which in turn makes this data available to the BEMS software.

The BEMS software creates a set of ODBC databases (MS Access is the default) independent of the WebAccess HMI & SCADA  databases.

The BEMS software creates a set of pre-formatted charts and reports commonly used in Energy Analysis of Buildings and Facilities.  These preformatted displays are best viewed at 1280 x 1024 pixels resolution or greater.
