How much electricity do the public buildings consume? Which energy source supplies each single household? Such questions are crucial when municipalities want to monitor their progress towards energy self-sufficiency. The foundations for a standardised energy monitoring system for municipalities and regions in Vorarlberg are currently being laid in the framework of CESBA Alps.

The federal state of Vorarlberg wants to become energy self-sufficient by 2050. This cannot be reached without efforts from the 96 municipalities. For monitoring their progress on energy saving, municipalities and regions need reliable data. Soon they might get these from a centralised energy database. A prototype is currently being developed within CESBA Alps and tested in the five municipalities of the Leiblachtal pilot region.

Data labyrinth makes analysis difficult

Data which is relevant for energy comes from several fields: the building stock is registered in an address database; the “chimney sweep” database provides information on CO2 emissions; the energy balance in the field of mobility can be measured as a result of specific surveys. All these different data are now stored in several places. If a municipality wants to do a comprehensive analysis, this is quite complex and challenging.

A centralised energy data base can be a useful support: it should pool as many energy relevant data as possible in one single structure. From this central database, municipalities and regions can analyse data in a standardised format in the shape of an energy monitoring report. This report makes it possible for municipalities to continuously monitor their progress in terms of energy issues.

Energy pilot region Leiblachtal

A protoype of the energy database is now being developed in the framework of CESBA Alps by alpS GmbH on behalf of the project partner Regional Development Vorarlberg and its subcontractor Telesis, in close coordination with the federal state of Vorarlberg and the Vorarlberg Energy Institute. In 2018 the prototype will be fed with energy data of the five Leiblachtal municipalities and first analysis will be performed – an energy and emissions balance of households and public buildings. The regional project partners are now checking the continued operation of the centralised energy database after the end of the pilot phase and its extension to all municipalities in Vorarlberg.
