Identification and thermal simulation in building industry

Abstract

The ISIBAT software (the acronym comes from the French for 'Building Identification and Simulation') was created at the France Telecom Research Center (CNET) in cooperation with the University of Brest. It is intended to identify and simulate the thermal behaviour of buildings housing any telecommunications equipment, but its fields of application are not limited to the thermal kinetics of building. Three examples are given to illustrate the performance of ISIBAT. The first concerns the design of outdoor distribution frame cabinets housing subscriber line equipment in which no heat dissipation occurs. The second is the analysis of a small remote telephone exchange with a heat dissipation below 2 kW, housed in a 10 m/sup 2/ building in a rural area. The third concerns a large exchange with a heat dissipation exceeding 10 kW installed in a 130 m/sup 2/ air-conditioned room. The results obtained in these three cases using ISIBAT are compared with those obtained using different evaluation methods.<>
