Baseline Review – Savona

• 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 CO2 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.

4. Options for improving energy

efficiency identified

5. Applying the DSS – possible options

• Space heating Sectioning the four main heat distribution lines to allow space heating of the sole

used portions of the building

Installing thermostatic valves and variable flow-rate distribution pumps to prevent overheating of single rooms/zones

• Efficient Domestic Hot Water (DHW) Production Using the main gas boiler to heat DHW for the kitchen instead of the electric boiler

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

Savona – Colombo Pertini School

• 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
