(July 2010)

Actions in the field of ENERGY1. Regional Energy Centre of Western Greece (1998-

2002)

2. City of Patras full signatory of the Covenant of Mayors

3. National initiative EXOIKONOMO (Energy Saving)

4. European Projects

5. Environmental Education / Change of Citizen Energy Behavior

6. Other actions

1. Regional Energy Centre of Western Greece (1998-2002*)

Basic conclusionsTransport the most energy-consuming (50%)

High electricity demand in housing sector (36%)

Strong dependence on fossil fuels, limited RES (2,1%)

Transport the highest percentage in CO2 emmissions(66%)

Public lighting 4% of energy consumption

*Suspended its action due to lack of funding

2. Covenant of MayorsSigned on 06/11/2008

Preparation of the Sustainable Energy Action Plan (SEAP) for the City of Patras is underway with the assistance of the National Centre for Renewable Energy Sources (CRES)

3. Program EXOIKONOMO (Energy Saving)Implementation of Energy Efficiency in

Municipalities (>10.000 inhabitants)

Aims at:Improvement of Energy Efficiency at local level

Promotion of Demonstration Actions with immediate results

Sensitisation of Citizens

Sensitisation of Local officials

3. Program EXOIKONOMO (Energy Saving) Axis 1: existing municipal buildings (55-65%)

Energy upgrade of the building shell for the reduction in heating and cooling demand

Energy upgrade of the electro-mechanical installations for the increase of energy efficiency of municipal buildings

Upgrade of the system of natural/artificial lighting Installation of energy management system (BEMS) with a

monitor for projecting the results to the citizens Axis 2: public urban spaces (15-25%)

Axis 3: urban transport (0-15%)

Axis 4: municipal technical infrastructure (0-4%)

Axis 5: dissemination, networking and updating of municipal officials (0-4%)

3. Program EXOIKONOMO (Energy Saving)Complete Action Plan (2009-2015)

Implementation Plan (2009-2012)70% funding from the program

3. Examples of interventionsBuilding Shell

External sunshadesThermal insulationReplacement of old windows, doors and framesGreen roof

Electromechanical installations for heating/coolingCentral air-conditioning instead of independent unitsReplacement of old boiler with newer of higher

performanceInsulation of the central heating column and of the pipes

Energy management (BEMS)Integrated Electronic management system

3. Dissemination, Networking, Publicity Information towards the Energy Manager of the

Municipality for the interventions and the proposed mode of function for the buildings

Information towards the Engineers of the Municipality

Presentation to Users of the Buildings (employees, citizens, students, teachers) of the interventions, the expected results and the functioning of the new systems

Annual evaluation of the energy consumption of the buildings and information to the users

6. Other ActionsSmall amounts of energy-saving lighting

introduced each year based on initiative of the Head of Department of City Lighting (e.g. Square Kapodistrias)

6. Other ActionsProcurement of energy-saving lighting for

periods of intense energy consumption (i.e. Christmas, Carnival)
