21 22 PART B: MODELLING ACTIVITIES

Part B reviews modelling activities carried out at national level. The questions seek qualitative assessments and responses to a number of topics (source data, the modelling objective and methodology, etc.) related to modelling and the associated costs. Three types of modelling activities are considered, namely:

To estimate the total fuel consumption in households by type of fuel and end-use To estimate the breakdown of the fuel consumption by end-use To model electricity consumption for the different appliances

5 Please, give the name and a short description of each modelling process used:

1. Calculation model RAKLAMM (see separate description) Calculation model for Space and Water Heating.

2. Calculation model for Heat Pump Energy Statistics (see separate description)

3. Calculation model for Home Appliances (see separate description)

23 6. For each modelling process identified in Part 5 please describe:

Model Name: RAKLAMM

1 Source data:

Give an overview of the key data sets that populate the model (surveys, administrative sources, other models). For the various sources, indicate the frequency of the data collection, an estimate of the robustness of the input data, and what other uses are made of the source data.

The model uses all relevant data and creates a system which is consistent and fits the frames. The model uses data on The Housing and Building Stock (described in the Survey-part) and degree day. The model uses also data obtained from the ‘Fuelwood Consumption in Small-sized dwellings’ -survey, District Heating Statistics and Household Budget Survey (all described in the Survey-part), Natural gas -statistics (data based on deliveries) and Statistics Finland’s Income Distribution Statistics.

2 Modelling objective:

Specify the objective of the modelling process, in particular whether:

a) The modelling process is a bottom-up estimation of the total fuel consumption in households (by fuel type and end-use). Specify the fuel(s) and end-uses (space heating / cooling, hot water, cooking, lighting and electrical appliances) modelled. Indicate any other relevant statistics (see recommended coverage in part A, point 4) which are part of the modelling output process. b) The modelling process aims at providing disaggregated statistics by end-use, i.e. the breakdown of fuel consumption for space heating, space cooling, water heating, cooking, lighting and electrical appliances. c) The modelling process aims at the disaggregation of electricity consumption in households by type of appliance (oven, fridge, compact fluorescent lamps, etc.)

Model uses both bottom-up and top-down estimations. Bottom-up estimations are used on peat and electric heating. Top-down estimations on wood (about every 7th year when survey is made, intervals bottom-up), natural gas, heat pumps and district heating.

3 Modelling methodology

Please, provide a description of the modelling methodology (including a web-link to published methodological papers). Indicate any external (independent) and internal reviews and their frequencies. Indicate frequency of modelling updates to take account of new technology (i.e. more energy efficient appliances) and new sources of data.

In the model space heating is calculated as the sum of the main heating system and the supplementary systems. The cubic capacity, annual specific consumption [kWh/m3,a]

24 and the heating degree days for residential buildings are taken into account when calculating the energy consumption of the main heating system. Supplementary heating systems that partly substitute the main heat source or supplement it are taken into account with reference to the use of various supplementary heating appliances.

The consumption of energy used for heating domestic water is calculated within the same model for space heating, based on occupant numbers. The problem is that there are no precise data on the consumption of domestic water per occupant. For the purposes of the model, assumptions have been made concerning the varying consumption of domestic water per occupant among the different types of buildings and heating systems.

The model has been developed in 1997 and thoroughly revised in 2011.

4 Reconciliation with other data

Please, provide an assessment of the accuracy of the modelling process of the overall consumption in the bottom-up approach (case "a" above). Indicate how bottom-up estimates are reconciled with aggregated energy balance data (supply side). What other independent variables are used in the reconciliation process.

Provide as assessment of the accuracy in the case of the disaggregation of total fuel consumption into the various end-uses (case "b" above). What other sources of data are there to validate this element of the modelling against?

The data that is based on bottom-up approach is compared with the total consumption of that source of energy. If there is difference, the data is then corrected with expert estimation.

5 Uses of the model outputs

Please describe how the results are used to inform / monitor /evaluate national policy. Describe the way the model outputs are published (internet, brochure, CD….), their frequency and timeliness. Give links of most recent results.

Space heating data is published on annual Energy Statistics compilation. The data is also published annually as a part of the Energy consumption in housing statistics.

26 Model Name: Heat Pump Energy Statistics 1 Source data:

Finnish Heat Pump Association collects the data on delivered heat pumps from heat pump producers and importers. Data is collected quarterly, but published only annually.

2 Modelling objective:

Specify the objective of the modelling process, in particular whether:

d) The modelling process is a bottom-up estimation of the total fuel consumption in households (by fuel type and end-use). Specify the fuel(s) and end-uses (space heating / cooling, hot water, cooking, lighting and electrical appliances) modelled. Indicate any other relevant statistics (see recommended coverage in part A, point 4) which are part of the modelling output process. e) The modelling process aims at providing disaggregated statistics by end-use, i.e. the breakdown of fuel consumption for space heating, space cooling, water heating, cooking, lighting and electrical appliances. f) The modelling process aims at the disaggregation of electricity consumption in households by type of appliance (oven, fridge, compact fluorescent lamps, etc.)

Model is calculating amount of heat generated and electricity used with single heat pump. Model does not disaggregate energy production or usage by end use (space heating and hot water)

3 Modelling methodology

Calculation model includes: - ground source heat pumps - air to air heat pumps - exhaust air heat pumps (heat recovery) Model does not include (at the moment) - air to water heat pumps

Total number of heat pump units for each year is delivered by Finnish Heat Pump Association SULPU. For each heat pump type total number of units is divided to different

27 regions and to different heating power. Heat generated by different heat pump types is calculated for normal year (30 year average). Energy generation and consumption is corrected for each year.

The Survey on Household Electricity Consumption 2006 divides the consumption of electricity in dwellings very precisely into specific types of equipment. Energy used for home appliances is obtained as the product of the number of appliances and data on the consumption for each appliance.

4 Reconciliation with other data

30 Provide as assessment of the accuracy in the case of the disaggregation of total fuel consumption into the various end-uses (case "b" above). What other sources of data are there to validate this element of the modelling against?

5 Uses of the model outputs

Home appliances data is published on annual Energy Statistics compilation. The data is also published annually as a part of the Energy consumption in housing statistics.
