1 PRODUCTION OF A MANUAL FOR STATISTICS ON ENERGY CONSUMPTION IN HOUSEHOLDS MESH PROJECT 3 rd Working Meeting Vienna, 3 rd October 2012 WP2: Global and Compendium Inventory Jesus Pedro García Montes IDAE – General Secretary – Planning and Studies Department

2 As we have defined the concept of "Best practices" M ESH PROJECT : P RODUCTION OF A M ANUAL FOR S TATISTICS ON E NERGY C ONSUMPTION IN H OUSEHOLDS “Innovative methodologies, procedures and statistical tools, which have been implemented by some country, and, in the basis of its experience, have proven to be effective for the achievement of the desired target, target that in the context of this research is defined as a set of transparent, detailed and flexible statistics on the energy consumption in households.” Key factors: 1.Innovation and excellence: real contribution of a practice VS. rest of common practices 2.Effectiveness and efficiency: achievement of the objectives, proven success and cost. 3.Transferability: identify transferable practices in a horizontal direction  experience gained by some countries may be transferred to other countries.

3 Methodology for identifying best practices M ESH PROJECT : P RODUCTION OF A M ANUAL FOR S TATISTICS ON E NERGY C ONSUMPTION IN H OUSEHOLDS Determinants for design operational criteria: 1.European Statistics Code of Practice. 2.Availability of information + requisite of homogeneity and comparability. Gathering information Process information Operational criteria Analysis Design operational criteria Types of operational criteria: 1.Surveys, administrative sources and “in situ” measurements. 2.Integrated approach. 3.Modeling.

4 SELECTION OF BEST PRACTICES: CRITERIA DEFINED FOR EXPERIENCES BASED ON SURVEYS, ADMINISTRATIVE SOURCES OR IN SITU MEASUREMENTS M ESH PROJECT : P RODUCTION OF A M ANUAL FOR S TATISTICS ON E NERGY C ONSUMPTION IN H OUSEHOLDS CriterionIndicator Mandatory character for the collection of the data 1.Compulsory character of the survey Impartiality and objectivity 1.Publication of the information on the implemented methodology for obtaining the information 1.Related to the institutional environment 2.Criteria related to the statistical process CriterionIndicator Design of the survey or data collection 1.Response rate achieved 1.Form of collecting the information Regular recurrence 1.Frequency 1.Planned future occurrence Units or subjects from which the information is extracted 1.Unit (households, energy suppliers, importers, traders, etc.) that are questioned or registered Territorial signification1.Regional level (NUT) where data are significant 3.Criteria related to the results CriterionIndicator Effectiveness1.Coverage rate Efficiency 1.Relationship between the sampling size and the cost of the operation 4.Criteria related to the statistical production CriterionIndicator Accuracy, reliability and quality 1.Existence of a system of validation with external or internal data 1.Performance of plausibility automated checks Spreading1.Publicity Accessibility1.Publication medium System of aggregation of the indicators

5 SELECTION OF BEST PRACTICES: CRITERIA DEFINED FOR THE EXPERIENCES RELATED TO THE APPLICATION OF INTEGRATED APPROACH AND MODELLING METHODS M ESH PROJECT : P RODUCTION OF A M ANUAL FOR S TATISTICS ON E NERGY C ONSUMPTION IN H OUSEHOLDS Due to its specific nature, a more qualitative approach has been articulated. Specifically, one based on the level of relative achievement, that is, comparing experiences, for the following principles:  Empirical contrast: comparison of different sources in order to detect possible deviations, discrepancies and/or contradictions, and as a method for improving the quality of the final data.  Reliability: it involves, on one hand, valid results, and on the other hand, results that represent the population. So, reliability involves existence of mechanisms for securing accomplishment of the initial specifications and detection of possible incongruities or mistakes.  Precision: it refers to the level of fairness with which the statistical information describes the phenomena to be measured.  Comprehensiveness and completeness: treatment of the phenomena applying an integral perspective. In addition to these, in the specific case of the methodology related to modeling, the requirements of the task force 2008 criteria have not been exactly applied due to the different nature of this type of method. These models have been classified into three types regarding the pursued objective. Specifically: A.Models aimed at estimating the energy consumption in the residential sector, taking into account the different types of commodities, end use and appliances. two groups: A.1.Models with a comprehensive perspective, which try to find the energy consumption by every kind of commodities, uses or appliances. A.2. Models considered specific, which make reference to a particular type of commodity or appliance. B.Models aimed at checking and validating data coming from other sources of information. C.Other models with different purposes.
