Energy source
Electricity, Oil, Gas etc
Data items Production Import Export Consumption
• Energy source– Consist of products identified in SIEC: Electricity, Oil, Gas etc .
• Data Items – Data items presented in chapter 6: Production, Import, Export,
Consumption etc.
3
Data item
Consumption
Manufacturing Service Household Agriculture
• Consumption – The use of energy source by
Household Manufacturing, construction and non-fuel mining industries Commerce and public Service Agriculture, forestry Fishing
• Suggestion: Include consumption in a subsection in chapter 4
4
Purpose and applications
• Overview of energy use, heating equipment and energy efficiency in industrial buildings within service industries.
• Users and applications
- Energy accounts
- Energy balances
- Emissions to air
- Primary material for analysis and research
5
Frequency and timeliness
• The first survey on energy use in service industries.
• Infrequent data collection. This survey will be published every second or third year.
• Temporary data are published 10 months after the reference year.
• Final data are published approximately 1.5 years after the reference year.
6
Population, sample and data sources
• Population - 74 000 industrial buildings within service industries.
• Sample - From the population, a sample consisting of approximately 8 100 buildings was drawn
• Data sources - Statistical data source
- Sample survey
- Administrative data sources - Central property, address and building register in Norway
(GAB/Matrikkelen) - Statistics Norway’s own SSB-GAB register. - Other public institutions (Statsbygg, Enova’s building network)

Data collection
• Based on questionnaire.
• The questionnaires are distributed in February and submitted by paper or electronically.
• The questionnaires are sent to landed property because of a lack of information on building owners.
• The Statistics Act is applied
• The deadline for returning the questionnaire is in March. There are two reminders, where the first notice is before the summer and the second notice with a final deadline in September.
• Those who fail to return the questionnaire by the final deadline may be reported to the Norwegian National Collection Agency for collection of the compulsory fine.

Data collection cont.
• Energy source– Electricity– Gas– District heating– Heating oils and paraffin– Wood and pellets
• Measurement units
• Includes all energy source used for– Room heating– Hot water – Cooling– Lighting– Electrical devices or other purposes
• Floor area
9
Data validation and editing
• Consistency check- Consist of checking whether there is a consistency between given
energy use and area (kWh/m2).
• Outliers- Buildings with unusually large or low energy intensity are closely
examined.
This includes buildings with:– Energy use over 500 kWh/m2 – Energy use below 100 kWh/m2
