1 Questionnaire TUNE WP 3 Workshop Energy data of Public Administrations 1. Which data are already collected in the municipalities? mainly: - Heat: 132 communities - Electricity: for buildings, street lightening, pumps, (waste-)pumps - water On average data related to power consumptions and heat consumptions are already collected as well as fuels consumptions. Water management has been outsourced: consequently data are available from Utilities and not from Municipalities no problem in this respect for energy consumptions (pumping), some problems related to water consumptions. Usually Municipalities collect economic data through excel sheets in the best cases but also without any tool to support data processing. APE FVG is trying to force Municipalities to adopt energy book-keeping systems (as the online energy cadastre) to monitor in detail energy flows and energy costs (at present around 50 Municipalities out of have started to work with our energy cadastre assistance and tutoring is fundamental to keep energy book-keeping systems alive in the Municipalities). Data referred to public buildings are difficult to collect: area, volumes, users, energy performance classifications require time to be collected and often are not sufficiently precise. Street lighting is well covered and sufficiently reliable. Power plants are often present and data are available (both nominal power and productions) where production is subsidized through public incentive schemes. Municipalities usually collect following data: - Annual/monthly energy costs of municipal buildings and facilities (heating/electricity) - Annual/monthly fuel costs for municipal vehicles and machines - Annual/monthly energy consumptions for heating and electricity of municipal buildings and facilities - Annual water consumption of municipal buildings and facilities - Annual/monthly energy production of municipal power generation plants and revenue from the sale

2 Veneto: The municipalities that entered the program ComuneClima/KlimaGemeinde (16 of 116 municipalities in the region nowadays) undertake an energy accountancy with EBO and collect the following data: - For communal buildings and facilities: annual electric consumption, heat consumption (per energy carrier) and water consumption Further data: building/facility typology (use and destination), warmed up gross surface or other reference values, number of building/facility users, typology of the heating system - For the municipal electricity generation plants: annual electricity production, % of renewable resources, % of self-consumption, net income from the sale of electricity - For district heating networks and cogeneration plants: annual consumption per energy carrier, annual electricity production, network efficiency losses - Annual total amount of purchased renewable electric energy - Unit energy costs of purchased energy per energy carrier ( /kwh) - Purchased energy carrier - Percentage of the energy costs sustained by the municipality - For communal vehicles: annual energy consumption in kwh per each fuel type, total number of kilometers travelled - For communal machines: annual energy consumption in kwh per each fuel type/energy carrier, total number of operating hours - For public lightning: annual electric energy consumption, light spot number, number of served citizens, lightened roads length Don t collect about consumption, only data: costs apart schools - Lightening - Heating - Water Data are not stored/managed 2. Who is in charge to collect data in municipalities? 1 supplier KELAG, heat: 5-10 small companies Law to collect the data from municipalities (Statistik Austria) On average and unfortunately energy data are collected by financial officers in charge to pay the bills. This means that more attention is put on economic aspects ( spent) than on energy flows (kwh or Smc consumed). In some Municipalities data are shared with technical offices in charge to manage public buildings. Bigger and more structured municipalities are usually arranged in a better way to collect and monitor energy data. As well, Municipalities with quality management systems (ISO9001, ISO14001, EMAS) are usually more structured with respect to energy bookkeeping activities. Our Agency is trying to force Municipalities to change their way of processing energy data giving priority to technical offices where there are more competences and more skilled people with respect to energy management.

3 Data are usually collected either by a municipal employee (administration or technical department). In some cases, this service is assigned to an external expert (energy consultant or Energy Team member). Veneto: Mostly financial department they collect cost data apart from school buildings Treviso: 15 people in environmental office 3. Are these data evaluated? No results At present, 90% of Municipalities pay the energy bills without any further evaluation of energy data. Usually, this necessity arises when requirements for public tenders force civil servants to look more in detail into energy data e.g. energy supply contracts. In this case, Municipalities face huge difficulties in getting relevant information from available data. Not always. a. If so, how are they evaluated? 46 e5 communities, have a good energy bookkeeping system, 5 evaluate the results it works; not enough time by the staff, they don t see the benefit, person should be inside the administration Except for Municipalities using the online energy cadastre of APE FVG, evaluation is carried out on the basis of personal skills and experience. A standard is missing! They are mostly evaluated inside the administration department. For municipalities participating in programmes as KlimaGemeinde or EEA, the data collected under EBO, will be evaluated inside the Energy Team by an energy manager, a ComuneClima consultant, a municipality energy referent. b. If so, are they yearly presented to decision-making bodies? Results are presented to the local council for political decisions

4 No. This is an objective within our online energy cadastre system. They are sometimes presented to the major or to the town council and eventually published on the communal journal or on the website. 4. Which data are interesting for the TUNE project, which data does the project need? Power production renewable energy systems Heat buildings, district heating Heat production - plants renewable energy systems Fuel consumption Number of inhabitants in the municipalities Net area Gross area Year of the establishment of the building Energy performance classification Number of users by building, working people or all people Opening hours: schools, theatres, sport gymnasium Clima data Christmas lightening Street lightening Inhabitants Vehicles: fuel type Total number of km /operating hours Number of vehicles E-mobility charging station (200 charging stations in Carinthia) Car sharing users - km Interesting data: Monthly based power consumptions (referred to buildings, plants, street lighting, vehicles, ) Monthly based power productions (refereed to RES installed) Monthly based heat consumptions (referred to buildings, district heating systems) Monthly based heat productions (referred to RES installed) Monthly based fuel consumptions (referred to vehicles owned by the Municipalities) Yearly based water consumptions Main data needed: Number of inhabitants for the Municipality For buildings managed by the Municipality: gross heated area (for everybody) [we prefer net heated area and gross volume] Year of establishment for buildings and plants or year of latest energy efficiency retrofit

5 Energy performance classifications should be required Number of users per building should be required: working people/users and school classes and number of events Number of opening hours for each building (daily and yearly and only for some buildings) For vehicles owned by the Municipality: Year of registration for each vehicle Fuelling system EU directive classification for each vehicle Number of kilometers for each vehicle Operating hours of other vehicles (trucks, snowplough, ) Number of charging stations Number of vehicles available for car sharing Numbers of kms travelled in car sharing All data that allow a benchmark with others municipalities in the Region or even outside that use an energy accountancy system. An important requirement for the feasibility is that the indicators will be calculated using the same reference data, otherwise they should be converted in order to allow benchmarking with other countries. 5. Which indicators are available in the region and which indicators are used and evaluated in the region? Absolute numbers heating systems, solar, photovoltaic but only in the e5 communities None is available and none is evaluated. The available data at a regional level are: - Annual electric consumption for domestic use per capita in kwh - Annual electric consumption for domestic use per family in kwh - Annual heat consumption per capita - CO2 emissions per capita (per year) - Annual electric consumption divided by sector: agriculture, industry, services, domestic use in Mio. kwh - Annual electric consumption per square meters in the building - Annual heat consumption fper square meters in the building - Annual amount of energy delivered by district heating networks - Heating degree days for each municipality

6 Which indicators are interesting and necessary for the TUNE project? Interesting for demand side: kwhe/m 2 /y kwhe/m 3 /y kwhe/user/y kwhth/m 2 (NG or diesel fuel or LPG) kwhth/m 3 or Sm 3 gas/m 3 /y kwhth/user/y or Sm 3 gas/user/y kwhe/inhabitant/y (for street lighting) Lwater/m 2 /y Lwater/user/y Lfuel/km/y Interesting for production side: kwhe/month kwhth/month kwhe/hour kwhth/hour Necessary for demand side: kwhe/m 2 /y kwhe/user/y kwhth/m 2 /y kwhth/user/y kwhe/inhabitant y (for street lighting) kwhe/km y Lwater/m 2 /y Necessary for production side: kwhe/month kwhth/month It s necessary to take in account climate data both for winter and for summer, for different type of buildings, if they have or not air conditioning systems and so on This is an open question to be investigated deeper! - Electric index for buildings and facilities (electric consumption in kwh/m 2 a or per user) - Heat index for buildings and facilities (heat consumption in kwh/m 2 a or per user) - Electric consumption in kwh per kilometers of lightened street and kwh per inhabitant for public lightning - Water index for buildings and facilities - Energy consumption per km/ per hour for municipal vehicles/machines - Energy production per inhabitant/ renewable energy production per inhabitant - CO2 emissions per m 2 a or per user - CO2 emissions per inhabitant

7 - all energy heating data have to be normalized on the basis of the heating degree day, using the same system for different countries (Italy HGT/20 Germany HGT/18 exc ) - for the CO2 emissions calculus should take into advise the different energy mix in the different countries ( if you want to benchmark on CO2, we need to convert taking into consideration these mixes). 6. Which software tools are currently used for data collection? Excel Facility management 1-2- Punkt Result is a traffic light system Quality of data is very low New: Department for Communities => SIEMENS tool Nothing (40% of Municipalities) Excel sheets (35% of Municipalities) Online energy cadastre of APE FVG (25% of Municipalities) Energie Bericht Online (KlimaGemeinde municipalities) EcoGisII (municipality of Merano) Excel tools Veneto: No tools rarely Excel sheets 7. Are these software tools also used for the evaluation or generation of key figures? Energie Bericht Online calculates the key indicators for the evaluation of heat and water consumption and shows them in form of charts Partly, better with the online energy cadastre. Energie Bericht Online calculates the key indicators for the evaluation of heat and water consumption and shows them in form of charts.eco GiS also generates key figures.

8 8. The software tool provides the evaluated indicators: No No a. With quality criteria (for example, traffic light system)? Indicators are compared with limit values and target values, there is also the possibility of benchmarking between different municipalities Yes b. Only the indicator (without description of the quality)? No c. In reported form with detailed explanation of the key figure? The EBO doesn't give information about the charts, but it contemplates the possibility to insert comments and explanations, which'll be inserted by the consultant that inserts the data and evaluates the report. No The EBO doesn't give information about the charts, but it contemplates the possibility to insert comments and explanations, which'll be inserted by the consultant that inserts the data and evaluates the report. d. Others

9 9. Who is currently evaluating the key figures in the community? The energy advisor or Land Kärnten consultant, the energy manager or the energy team The Agency or, in the biggest Municipalities, the energy manager The energy advisor or Comune Clima consultant, the energy manager or the energy team 10. Are there any persons in the municipalities who are responsible for the collection and evaluation and who also have competences for immediate measures? The energy manager or those working in the technical office The energy manager or those working in the technical office The person that collects the data does not always have the technical knowledge to evaluate the data and the report, in fact in most cases this procedure is delegated to a municipal employee with relatively low competence in the technical and energetic sector. When data are collected by an energy consultant or an energy advisor, they are capable of evaluating the results, it depends on the case, the biggest municipalities have frequently qualified people in the matter, the smallest ones are less likely to have them.

10 11. What do you think is missing in order to build a functioning key code system in the municipalities? User friendly software Shared standard Shared standard Automatic procedures User friendly software Open and low cost software Support & tutoring Low cost outsourcing alternative Easy to read information There is a leak of human resources dedicated to the collection and evaluation of energy consumption s data. The simplification of the data collection is desirable, the best thing would be to gather data directly from electric and heat energy supplier, in particular in form of an Excel sheet associated with a code, so that it would be possible to upload them automatically in the energy accounting system. 12. What does this system need so that the municipalities have added value from the collection and analysis of the data? Possibility to print a final annual report and choosing which part to insert in it. Possibility to have a benchmark with indicators in others municipalities of the same region and also a benchmark with other countries in which different energetic accounting systems and indicators are used (Austria, Germany, ) Be straightforward, simple, easy to use, user-friendly, fast Provide useful information to taking decisions on possible investments (DSS) Low cost solutions Policy support and interest Possibility to print a final annual report and choosing which part to insert in it. Possibility to have a benchmark with indicators in others municipalities of the same region and also a benchmark with other countries in which different energetic accounting systems and indicators are used (Austria, Germany, ) Generation of intuitive charts that can give an immediate image of the goodness of the efficiency of the object. Maybe it would be useful for the communication to have one or two global indexes, in order to identify the efficiency grade of a municipality and, if possible, to push an improvement. Possibility to have at least one internal expert in this field of competence in each municipality.
