Chapter 5aHousehold consumption: identify services and uses into the houses

• 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 10aTop-down International best practises

• 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.

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

Chapter 2Household consumption: identify services and uses into the houses

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

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
