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)
LDK - ENERinTOWN Page 7
Project Activities
Continuous Energy Consumption Monitoring of Selected Municipal Buildings.
Establishment of a Municipal Energy Management Tool for acquisition and processing of key energy consumption data.
Creation of the figure of Municipal Energy Manager.
Implementation of low-cost & high impact energy efficiency measures to reveal feasibility and best practice.
LDK - ENERinTOWN Page 8
Expected Results – Benefits (1)
Design and Provision of relevant equipment and software for the establishment of the Municipal Energy Management Centres.
Selection of a web-based Energy Management Software and integration with the automated metering system.
Networking of Municipal Energy Managers at a EU-wide scale to exchange experiences and best practices in facilities management.
LDK - ENERinTOWN Page 9
Expected Results – Benefits (2)
Implementation of a set of low-cost energy
saving measures and evaluation of their impact
on energy consumption. Development of Municipal Guide for the
procurement of Energy Efficient equipment and the operation of the municipal building installations.
Dissemination actions for the promotion of best
practices and development of case studies for
future similar actions.
LDK - ENERinTOWN Page 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).

Different Approaches (1)
France – Monitoring of electricity & gas via internet & open source SW (turn-key contract)
Germany – Monitoring of heat, electricity, gas & water via internet (turn-key contract)
Greece – Monitoring of electricity & gas via the internet (various suppliers)
Ireland – Monitoring of electricity & gas via internet, GSM (preferred), manual transfer
Italy – Monitoring of electricity & gas via GSM (turn-key contract)
LDK - ENERinTOWN Page 14
Different Approaches (2)
Lithuania – Monitoring of heat, electricity, gas via internet (turn-key contract)
Portugal – Monitoring of electricity & gas via a mixed RF/GSM solution (turn-key contract)
Spain (Galicia) – Monitoring of electricity gas, & oil via internet or manual transfer (various suppliers)
Spain (Basque) – Monitoring of electricity & gas via internet (turn-key contract)
LDK - ENERinTOWN Page 15
Different Approaches - Summary
Turn-key solutions minimise technical risk but increase overall cost
GSM is technically preferable over hard-wire connection, but costs twice as much
RF communication is not very reliable and thus oriented to specific installations
Liquid fuels are hard to be measured by the system and heat metering is applied only in Northern EU countries
LDK - ENERinTOWN Page 16
Focus on the Greek Solution (1)
Two Municipalities: Maroussi & Egaleo
2 Swimming Pools 1 City Hall 9 School Buildings
(incl. secondary installations e.g. gyms, halls, etc)
LDK - ENERinTOWN Page 17
Focus on the Greek Solution (2)
LV Electricity Meters with digital pulse input facility have been selected
Reed switch generates pulse from the gas meter
Recorded data (electrical & gas volume) are transferred via serial communication (RS-485) to a local PC
An RS-485 to RS-232 is required
LDK - ENERinTOWN Page 18
Focus on the Greek Solution (3)
An in-house data acquisition SW is used for the data collection, local storage and transfer to the database
Local PC should run Win 98 (and higher) and be connected to the internet
LDK - ENERinTOWN Page 19
Focus on the Greek Solution (4)
All data available at the database will be accessible via the web-based Energy Management Software
Transfer between the Municipal Management Centre and the mirror database of the Energy Management Software (Security)
LDK - ENERinTOWN Page 20
So Far Assessment
Collected data and in particular energy consumption profiles are very useful for the Municipalities & respective Utilities
In spite of its large volume - Significant barriers do exist while trying to introduce energy monitoring in this particular consumer category
LDK - ENERinTOWN Page 21
Limitations – Lessons Learnt
Technical Gas Connection & Building Installations Layout of the existing installation affects
the cost Market
LV Meters with communication are scarce Harmonisation in communication protocols
Administrative Decision Makers commitment Unavailability of funding
