ITU‐T's Technical Reports and Specifications 463 1.8 Underlying philosophy The preceding exams are comparitively superficial with the potential of intelligent building concept providing far greater benefits. The single spine is usually represented by physical security information management (PSIM). The significant advantage of intelligent buildings is that they can constantly monitor current operations in context and automatically adjust resources for optimum efficiency while identifying and accuarately informing key decisions in a timely manner. This can range from the routine such as variance to the preventative maintenance schedules to automated restocking and repair according to changes in the normal pattern of use. For example, Canadian Forces Station (CFS) Alert is the most northerly, permanently inhabited location in the world, located only 817 kilometres from the geographic North Pole. CFS Eureka is a intelligent building that advises the Canadian Department of Defense Headquarters in Ottawa, Canada when it is in use and automatically compiles its resupply and repair requirements for each season deployment to the High Arctic. The expectation is that it will in the future inform and enable change of use capabilities, enhancing through life value.

The benefits which accrue to the building have been briefly described and may be summarized by: A more efficient building; Implementation of communications as a \"fourth utility\" which results in only one communications backbone for all applications (in some jurisdictions, fire or other life safety systems may need to be segregated into an additional communications infrastructure to comply with local ordinances) and; Energy savings, maintenance savings and staffing savings will generally arise as an indirect benefit of each of the individual efficiencies.
