3. Savona has produced a Sustainable Energy Action Plan, that was expected to be officially adopted by the end of July 2014. No specific targets for CO 2 emissions and energy reduction are set for the municipal buildings of the city individually. The input data for the assessment framework were obtained by the Energy Manager of the municipality of Savona. 1.OVERVIEW 2.The SCEAF - Inputting data 3.The SCEAF - Outputs 4.

7. Programming of the space heating system according to the real energy needs, to propose an operational schedule: Input: School schedule, indoor and outdoor temperature, energy profile of the complex Output: Time to switch on and off the boilers, distribution lines to be switched on and off. Programme for optimally managing the Hot Water Production according to the real use of the school Input: School schedule, weather conditions, energy prices Output: A weekly schedule of switching on/off the boilers Optimally maintaining the PV of the school, by comparing the observed energy production with the expected (exploit the Savona Campus DEMS that predicts PV energy production) Input: Weather data (temperature humidity, wind etc.) Output: Weekly indication of expected production 1.OVERVIEW 2.The SCEAF - Inputting data 3.The SCEAF - Outputs 4.
