The analysis made previously can only have a theoretical value if it is not supported with real consumption measured data, useful to give more objectivity to the analysis. Taking into account the consumption measured, as heat transferred from thermal power plants to the school buildings, measured quarterly between 2003 and 2008 by counters. The long period of analysis gives the possibility to exclude the errors due to a measurement system based on estimates and subsequent compensation, considering a yearly average value. To obtain a value of global energy needs, it is assumed for all these buildings a boiler's efficiency of 85%.
