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

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.

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 sent to landed property because of a lack of
information on building owners.
•
•
The Statistics Act is applied
•
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.
The questionnaires are distributed in February and submitted by paper
or electronically.
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.

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
• Comparison with other sources
