Abstract
A set of all electric telecommunication fixed-line switching plants were monitored in order to analyze the energy use for telecommunication equipment and air conditioning system. Indeed these energy systems need a great deal of energy; air conditioning get to 30-40 % of the total energy use. The aim of the study was to apply tools for energy management and to define strategies aimed at making these systems more energy efficient. With the aim of simulating the typical energy behavior of the system and identifying the opportunity for energy savings measures, a numerical model was carried out . The mathematical relationship among the measured data was obtained by means of statistical analysis. The energy consumptions were linked to the main influencing factors. The study shows that such mathematical model accurately reproduce the energy behavior of the switching plants. In addition, indexes to track the performances of HVAC and electrical systems and energy management tools are applied and propose
