6. LDK - ENERinTOWNPage 6 Objective of the Project The reduction of energy consumption of municipal buildings by means of: continuous monitoring over the internet implementation of low cost energy saving measures, and adoption of energy efficiency standards and practices for the selection of equipment and operation of the buildings (in the long run)

7. LDK - ENERinTOWNPage 7 Project Activities ñContinuous Energy Consumption Monitoring of Selected Municipal Buildings. ñEstablishment of a Municipal Energy Management Tool for acquisition and processing of key energy consumption data. ñCreation of the figure of Municipal Energy Manager. ñImplementation of low-cost & high impact energy efficiency measures to reveal feasibility and best practice.

8. LDK - ENERinTOWNPage 8 Expected Results – Benefits (1) l Design and Provision of relevant equipment and software for the establishment of the Municipal Energy Management Centres. l Selection of a web-based Energy Management Software and integration with the automated metering system. l Networking of Municipal Energy Managers at a EU-wide scale to exchange experiences and best practices in facilities management.

9. LDK - ENERinTOWNPage 9 Expected Results – Benefits (2) l Implementation of a set of low-cost energy saving measures and evaluation of their impact on energy consumption. l Development of Municipal Guide for the procurement of Energy Efficient equipment and the operation of the municipal building installations. l Dissemination actions for the promotion of best practices and development of case studies for future similar actions.

10. LDK - ENERinTOWNPage 10 Contribution of the Municipalities  Assistance through the Selection of Buildings.  Provision of Technical Staff for the installation of the necessary monitoring equipment.  Selection of the Energy Manager.  Implementation of part of the low-cost measures (non-mandatory).

13. LDK - ENERinTOWNPage 13 Different Approaches (1) l France – Monitoring of electricity & gas via internet & open source SW (turn-key contract) l Germany – Monitoring of heat, electricity, gas & water via internet (turn-key contract) l Greece – Monitoring of electricity & gas via the internet (various suppliers) l Ireland – Monitoring of electricity & gas via internet, GSM (preferred), manual transfer l Italy – Monitoring of electricity & gas via GSM (turn-key contract)

14. LDK - ENERinTOWNPage 14 Different Approaches (2) l Lithuania – Monitoring of heat, electricity, gas via internet (turn-key contract) l Portugal – Monitoring of electricity & gas via a mixed RF/GSM solution (turn-key contract) l Spain (Galicia) – Monitoring of electricity gas, & oil via internet or manual transfer (various suppliers) l Spain (Basque) – Monitoring of electricity & gas via internet (turn-key contract)

15. LDK - ENERinTOWNPage 15 Different Approaches - Summary l Turn-key solutions minimise technical risk but increase overall cost l GSM is technically preferable over hard- wire connection, but costs twice as much l RF communication is not very reliable and thus oriented to specific installations l Liquid fuels are hard to be measured by the system and heat metering is applied only in Northern EU countries

16. LDK - ENERinTOWNPage 16 Focus on the Greek Solution (1) l Two Municipalities: Maroussi & Egaleo l 2 Swimming Pools l 1 City Hall l 9 School Buildings (incl. secondary installations e.g. gyms, halls, etc)

17. LDK - ENERinTOWNPage 17 Focus on the Greek Solution (2) l LV Electricity Meters with digital pulse input facility have been selected l Reed switch generates pulse from the gas meter l Recorded data (electrical & gas volume) are transferred via serial communication (RS-485) to a local PC l An RS-485 to RS-232 is required

18. LDK - ENERinTOWNPage 18 Focus on the Greek Solution (3) l An in-house data acquisition SW is used for the data collection, local storage and transfer to the database l Local PC should run Win 98 (and higher) and be connected to the internet

19. LDK - ENERinTOWNPage 19 Focus on the Greek Solution (4) l All data available at the database will be accessible via the web-based Energy Management Software l Transfer between the Municipal Management Centre and the mirror database of the Energy Management Software (Security)

20. LDK - ENERinTOWNPage 20 So Far Assessment l Collected data and in particular energy consumption profiles are very useful for the Municipalities & respective Utilities l In spite of its large volume - Significant barriers do exist while trying to introduce energy monitoring in this particular consumer category

21. LDK - ENERinTOWNPage 21 Limitations – Lessons Learnt l Technical u Gas Connection & Building Installations u Layout of the existing installation affects the cost l Market u LV Meters with communication are scarce u Harmonisation in communication protocols l Administrative u Decision Makers commitment u Unavailability of funding
