Baseline Review – Savona 1. OVERVIEW 2. The SCEAF Inputting data 3. The SCEAF Outputs 4. Options for improving energy efficiency identified 5. Applying the DSS – possible options Savona – Colombo Pertini School • Space heating ü Sectioning the four main heat distribution lines to allow space heating of the sole used portions of the building ü Installing thermostatic valves and variable flow-rate distribution pumps to prevent overheating of single rooms/zones • Efficient Domestic Hot Water (DHW) Production ü Using the main gas boiler to heat DHW for the kitchen instead of the electric boiler ü Installing timer driven switches on the (other) electric boilers to heat water in the needed period only during low tariff times • Efficient lighting through use of LEDs, timers and sensors (movement/light) • Need to reclaim parts of the plant with cement/asbestos thermal insulation

Baseline Review – Savona 1. OVERVIEW 2. The SCEAF Inputting data 3. The SCEAF Outputs 4. Options for improving energy efficiency identified 5. Applying the DSS – possible options Savona – Colombo Pertini School • Programming of the space heating system according to the real energy needs, to propose an operational schedule: ü ü • Programme for optimally managing the Hot Water Production according to the real use of the school ü ü • 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. 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) ü ü Input: Weather data (temperature humidity, wind etc. ) Output: Weekly indication of expected production

Pilot site visits - Savona Documents Collected • • • Colombo Pertini energy profile summary A hardcopy of the unofficial version of Savona’s SEAP Electricity records for municipal buildings of 2012 Energy bills, both thermal and electricity, for the past 3 years Energy Certificate of school Building plans of school Schedule of the gym’s operating hours and school operational schedule Data sheets of boilers, heating pump, A/C and photovoltaic plant Building plants filled with operational details Brochure of Climatel Documents Expected • • Electricity bills of 2013 Natural Gas bills of 2012
