1 What do successful joint actions look like? Dr. Karl-Ludwig Schibel Climate Alliance Italy International Climate Alliance Conference 2018 Energy transition in cities and regions Barcelona, Oct, 2 11:30-13:30

2 Energy efficiency (in public buildings): a huge subject The problem of Energy Efficiency in buildings According to Commission data, buildings are responsible for 40% of energy consumption and 36% of CO 2 emissions in the EU. Currently, about 35% of EU buildings are over 50 years old. By improving the energy efficiency of buildings, total EU energy consumption could be reduced by 5% to 6%, whilst CO 2 emissions would decrease by about 5%. The retrofitting rate is highly unsatisfactory, not only in the private sector but also in the public one, which is far below the 3% annual renovation target for public buildings.

3 The challenges of energy efficiency in public buildings SWOT-Analysis Strengths Many local authorities have an energy plan, usually a SEAP, and an energy manager State government has adopted a climate protection law Opportunities Weaknesses Financially weak local authorities Lack of political commitment Insufficient technical knowledge Insufficient knowledge of funds Lack of capability to develop financial strategy Bad project design Lack of qualified ESCOs and enterprises Threats Change perspective to life-cycle costs Rising energy costs Rising awareness in local authorities about long-term cost-saving effects of energy-efficiency measures Log-In-Investments Change of destination of building

4 The Interreg MED community

5 THE ENERJ approach Build on existing projects, above all existing SEAPs/SECAPs (Covenant of Mayors), but also other Energy Plans do a Territorial Context Analysis. Look at the energy efficiency measures planned in public buildings in the SEAPs/SECAPs of the territory and where they overlap. put the data on a collaborative web platform elaborate Joint Actions facilitate their implementation through Joint Actions coordinators

6 Example: Anatoliki S.A. Development Agency of Eastern Thessaloniki s Local Authorities (Greece) SEAPs of: Thermi, Pilea-Hortiatis and Thermaikos Approved: Monitoring: Thermi fully monitored in 2016 Energy Audit: public buildings of Thermi, Pilea-Hortiatis, Kalamaria, Trilofo

7 Audits Overview 12 buildings 4 Municipal & 8 schools (+ 2 extra included) Located in three Municipalities of eastern Thessaloniki Joint Audits aim Coordination with Municipalities Target buildings selection, in collaboration with the interested Municipalities Joint Tender for all buildings preparation and publishment Sub-contractor: C. Tzinis & K. Hantzios

8 Steps followed Structural - electromechanical and energy consumption data gathered On the spot audits performed Code of Energy Performance of Buildings (KENAK) is followed, applying the Technical guidance of the Technical Chamber (TOTEE /2010) TEE-KENAK software has been used - Reference building principle is followed

9 Steps followed Primary energy consumption per energy source calculation Buildings classification, compared to a reference building of B energy class Interventions proposition (including RES) and energy class recalculation Payback period estimation

10 Energy Consumption reduction (%) Energy Consumption reduction (%) Overall Analysis Which will be the overall (& per Municipality) energy consumption gains if all most efficient interventions will be applied? What is the gain if all less efficient interventions will be applied? 70% 70% 60% 60% 50% 50% 40% 40% 30% 30% 20% 20% 10% 10% 0% All Buildings 0% Thermi P-H Kalamaria Minimum Potenial Energy Reduction Maximum Potential Energy Reduction

11 Cost ( ) Cost ( ) Overall Analysis Which are the respective costs? All Buildings 0 Thermi P-H Kalamaria Minimum Potenial Energy Reduction Maximum Potential Energy Reduction

12 Years of Payback Payback Years Overall Analysis Which will be the overall average payback period if all most efficient interventions will be applied? What is the average payback period if all less efficient interventions will be applied? Which is the actual payback period per building? 17,00 16,50 16,00 15,50 15,00 14,50 14,00 All Buildings Minimum Potenial Energy Reduction Maximum Potential Energy Reduction

13 What good examples do you know of energy efficiency measures in public buildings were a group of local governments acted together?
