2、 intelligent buildings: multitenant and single-tenant. Multitenant buildings belong to a leasing agency which hopes to use the value-added services offered by the intelligence building to increase its revenues by renting or leasing to tenants not just office space but an attractive bundle of service
3、s as well. In this case, many business tenants occupy the building and share services. Single-tenant buildings are occupied by a single enterprise such as corporate headquarters or branches which arranges the “intelligence” of the building to suit its corporate goals. In this kind of building usuall
4、y the occupant is also its owner. The motivation for providing this building with intelligence is not to create revenues for the owner as in a multitenant building, but rather to help the enterprise to realize its corporate goals in a more effective manner. University, hospital, governmental, and in
5、dustrial campuses form a special case of single-tenant buildings. For example, universities are looking for means of offering a wide range of computer and telecommunications services to students, faculty, and administrators and to employ more effectively the professorial staff, for instance, by find
6、ing ways of allowing professors to give their courses to what are often progressively larger and larger classes. Hence we see the emergence of the so-called “wired campus” and the first steps towards turning to intelligent building techniques for solutions to this situation.Multitenant Building Exam
7、ples of this class of buildings include:*Rockefeller Center in New York*Software Productivity Consortium in Herndon, Virginia*The Galleria in Dallas*Informant in Dallas*50 Wall Street in New York *Marathon Plaza Building in San Francisco*City Crop Building 1 in San FranciscoFor the most part, these
8、buildings are large high-rise towers (thirty-to-fifty-floor range) and groupings of such towers. The elevators of one “speak” to their passengers and give weather news if the passengers request it. In another, infrared detectors turn the office lights on when its occupants enter, turning them off tw
9、elve minutes after everybody leaves. Thousands of sensors detect temperature changes in the internal environment within a tenth of a degree. In case of fire, other sensors will set off alarms and inform the fire department and the police as well as move the elevators to strategic locations.These bui
10、ldings are serviced by advanced telephone systems, allowing every tenant to have his own direct lines and access to a large range of telephone and telecommunications service options. We shall examine such options later, but, for example, in the case of long-distance calls, this system attempts to de
11、termine the routing of the call most advantageous to the tenant. We must observe here that in the United States in particular the importance of this kind of service is non-negligible thanks to the dismantling of telecommunications deregulation in general; services previously provided automatically b
12、y the local telephone company must now often by decided by the subscriber, who often finds himself confronted with a bewildering array of choices, couched in a language unfamiliar (and basically of no interest) to him. The building managers therefore take over this task as one of the services of the
13、 intelligent building. We note in passing that other industrial countries have introduced some sort of deregulation, allowing clients to determine their choice of internal telephone systems.Example of an Intelligent Tower This example of an intelligent tower, a real case history in the United States
14、, displays a number of intelligent buildings features. The STS are:* Rooftop communications: satellites and microwave* Security: optional card-controlled access* Data processing: ability to install LANs and commercial software*Television/video: shared networks and satellite broadcast antennas (trans
15、mit and receive) The integrated building management is:*EMCS: automated and computerized, shares common cable plant and automatically maintains temperature, humidity, and ventilation* Security: computer control of elevators, emergency electricity and lighting, smoke and fire detection, controls building evacuation in emergencies and the elevators and sends instructions throughout the building, and overlooks the parking area (immediate revision of tenants status if needed).Single-Tenant Buildings Example
