ITU‐T's Technical Reports and Specifications 475 6 Examples of Intelligent buildings 6.1 Molson Center The Molson Centre, is a 20,000+ seat capacity arena located in Montreal, Canada. In this facility the inactive building can be safely managed and monitored by two individuals. Monitoring the screen with the ability to occasionally dispatch the second individual to validate, verify or to address a situation should it arise. The integration of the systems includes access control, intrusion, surveillance, hold up alarms, elevators, fire alarm system, paging system, television displays throughout the building, emergency evacuation systems/address systems, ice surface management, voice, data and restaurant systems, beer dispensing systems, food storage and kitchen systems, parking systems, water leakage systems, electronic photoflash systems and systems for the hard of hearing or simultaneous translation. While the list is extensive there are some key novel features which were introduced into this building. The Authorities Having Jurisdiction (AHJ) permitted the use of the public address system for emergency evacuation purposes providing certain safeguards were fully demonstrated (which were successfully accomplished). The building may be locked when occupied under special provisions permitted by the AHJ. All communications are handled through a single common utility (common backbone) thereby eliminating individual and independent communications systems used for each application.

Special features were incorporated on the telephone and audio systems for broadcasting and reporter purposes. Access control cards used by guards automatically from a \"guard tour\" reporting on the progress of a guard moving along a randomized but defined sequence of doors. Aberrations and unexpected delays automatically initiate alarms. These same cards can function as a signal to activate or extinguish selected lights.
