13 Development: energy consumption stats in HH Task Force: Members: Volunteering countries: AT, FR, DE, DK, UK Tasks: 1. Elaborate Review Reports of all national systems in the EU 2. Elaborated recommendations for HH data collection (coverage) 13

Elaborate Review Reports of all national systems in the EU 2.

14 Priorities for survey coverage 1. Housing Stock Characteristics Ownership type, dwelling type, age, insulation, surface heated / air-conditioned 2. Household characteristics Household size, income, intensity of occupation of the dwelling 3. Consumption / expenditure of energy commodities Consumption and associated cost per type of energy commodity (electricity, heat and major fuels) 4. Space Heating Main/supplementary space heating system: fuel type, type of heating equipment, age of equipment Availability and type of temperature control instruments (thermostats) 5. Hot Water Water heating equipment: fuel type, tank size, age 6. Cooking Cooking equipment: fuel type, equipment type, age 7. Electrical appliances Availability of electrical appliances: type, number, age 8. Air conditioning Air conditioning equipment: type, age 9. Penetration of Energy efficiency Technologies labelled equipment by appliance type, high efficiency condensing boilers, high efficiency lamps Retrofitting in view of improved energy saving: dwelling, heating / air-conditioning equipment 10. Energy service demand Intensity of use of heating, air conditioning; heating and cooling setpoints (thermostats) 11. Penetration of renewable Energy Sources Solar panels (surface, power, type), biomass (by type), heat pumps (type/power, electricity consumption) 12. Energy consumption by end-use Based on modelling: space heating, water heating, cooking, space cooling, lighting and electrical appliances 14

17 National Systems Approaches to HH surveys 1. Dedicated regular surveys of households: Annual: ES, IE, NL, SV, BE(FL) 2-yearly: AT, DE 3-yearly: FR, LV 6-10 yearly: CZ, PT, SI 2. Other surveys: ad-hoc or addressing specific issues (e.g. firewood): AT, DK, ES, FI, HU, IE, NL, PL, BE(WAL, BR) 3. Modelling of Energy Consumption in Households UK, CH 4. Other Sources Population census Household Budget Survey Surveys of suppliers 17

6-10 yearly: CZ, PT, SI 2. Other surveys: ad-hoc or addressing

18 National Systems Approaches to HH surveys Housing stock characteristics Systematic data: 17 MS Type/age of building best known Poor availability on insulation/heated floor surface Household characteristics Systematic data: 18 MS Mostly disconnected (in particular income) from energy (HBS) Consumption by commodity type Systematic data: 16 MS Commodity type better known than Quantities: 16 MS Expenditure: 15 MS Quantities and expenditure data often come from different surveys 18

19 National Systems Approaches to HH surveys Fuel type by use Systematic data: 15 MS Varying coverage of detail: Space heating: 14 MS Hot water: 12 Cooking: 8 Space heating system Systematic data: 15 MS Details vary e.g. age of heating system: only 7 MS Availability of electrical appliances Systematic data: 15 MS 19

20 National Systems Approaches to HH surveys Penetration of renewable energy Systematic data: 16 MS but varying completeness: Wood quantities: 16 Solar collectors: 11 Photovoltaics: 10 Heat pumps: 8! Penetration of energy efficiency technologies Systematic data: 5 MS AT: lamp types, energy labelling BE: existence of knowledge, energy labelling IE: CFL light SV: measures implemented since 1997 (isolation, lighting, recycling of ventilation, ) 20

21 Modelling AT: Intermediary space heating with temp corr BE: household consumption by fuel and use CZ: households biomass consumption DK:district heating consumption per unit and electrical space heating unit consumption UK:detailed household consumption breakdown by fuel and use CH: Analysis for all sectors (industry, transport, households and services) 21

22 Reported costs - Surveys Wide range: Minimum: as low as ,- Maximum: up to ,- SV: metering electric consumption ,- Average national cost: apr ,- BUT: difficult to make a meaningful average! 22

23 Reported costs - Modelling Only 2 countries report expenses: UK: apr ,- /year CH: apr ,- /year (for bi-annual updates only) 23

24 Some more general conclusions Needs differ between Member States - and therefore also the applied solutions Statistical infrastructure is in a varying state of availability Further development must include methodology to ensure international coherence Costs and resources are addressed by: Use of models Use of existing surveys for complementary questions Household Budget Survey Census Resources being a general issue, Eurostat grants may be helpful to move forward 24

25 Present initiatives: state of progress Grants: state of play Total budgeted envelope: ,- Participating MS: 17 AT, BE, BG, CY, DK, EE, ES, FI, GR, IT, LT, LV, MT, PL, PT, RO, SI Actions will run until end 2012 Data collection through: Surveys BE, BG, CY, DK, EE, ES, GR, IT, LT, LV, MT, PL, PT, RO, SI Modelling FI, SI Combining several sources AT, ES Direct measuring BG, ES, MT 25

26 Methodological work Statistical development requires uniform methodology Need to address proper coherence of the national actions Eurostat is proposing the development of a statistical manual Expertise is needed from various sources Experience from existing/past experience Knowledge on existing definitions/methodology Cost and resource awareness The most promising option seems to be initiative from experienced MS officials 26
