Integrated Building Management System (iBMS) focus is on:

Facilitating total control of building management function at a fingertip.
Buildings being automated are not only economically optimized, but also reduce CO2 emissions for increased sustainability and a better future. A well designed BMS will help all of buildings systems run as efficiently and safely as possible
AIA Integrated Building Management System (iBMS) is a central intelligent system installed in a building, which automatically monitors and controls all mechanical, electrical and security equipment. While managing various building systems, it ensures the operational performance of the facility as well as the comfort and safety of building occupant.
Integrated Building Management System (iBMS) core functionality keeps the building climate within a specified range, provides lighting based on an occupancy schedule, and monitors system performance and alerts regarding device failures.
