  1. Statistics Netherlands May 4, 2012 ESSNET/MESH meeting Madrid

  2. Is it sufficiently clear what kind of methodologies to put in 5a,5b,5c,5d,6? • Contents you miss in draft outline 5a? • Contents you would like included? Chapter 5aHousehold consumption: identify services and uses into the houses

  3. Do we merge the best practises into the methodology chapters? • How many best practises do we want? • How many can we get? • What level of detail? If 3 best practises for each methodology, and 3 pages = 27 pages. Chapter 10aTop-down International best practises

  4. IEA used this template for their good practise in the EE manual. - What do we like from this?- What would we do different?

  5. Alternative title? Introduction to HH e.cons? • Contents you miss in draft outline 2? • Contents you would like included? Chapter 2Household consumption: identify services and uses into the houses

  6. Chapter 2 : proposed outline • Why knowing about energy consumption of households matters • Policy: EPBD, energy efficiency, climate and energy targets, • A figure displaying the share of households in total EU energy consumption. • How do we define a household? • Residential sector, dwelling, household types, small businesses/farms • Common definitions or at least a list of categories to consider for inclusion or exclusion • What sources of energy are used? • Electricity. • Gas. • Renewables. • Coal, oil, etc... • Units and conversion factors: kWh, m3, GJ… • A Figure/pie chart: % of household energy by energy source (NL as example, EU if available) • How is energy used in households? • Common breakdowns of uses • Heating, cooling, cooking, lighting, hot water, … • Diagram/illustration of house with energy flows • Figure/pie chart: % of household energy by use (NL as example, EU if available) • What factors influence how much energy is used in a household? • Household size, degree-days, insulation, technology, the whole variable list or a condensed version JongCBS Visit Austria

  7. Chapter 5a: proposed outline • What do we mean by suppliers? (or some clear definition of the chapter subject) • Types of information sourced from suppliers • Total household energy consumption • Examples: grid managers in Brussels, NL, Spain, Ireland • Pitfalls and lessons learned • Common issues and how to deal with them • Equipment/appliance sales • (NL) Solar panels • Refrigerators • (NL) Heat pumps • From sales figures to appliance stocks and energy use • List of models and assumptions actually used • General strengths and weaknesses of using supplier data • Strengths: survey/admin burden reduced, • Weaknesses: suppliers usually don’t know what is sold for household purposes. Non-standard definitions… • Costs, man-hours, skills • How to get information from suppliers • General considerations • Developing new legal requirements • (time required, steps needed, problems encountered) • Voluntary cooperation • Seeking win-win situations • Examples • Recommendations for further development of appliances energy use JongCBS Visit Austria
