ASSESSMENT OF DATA
(a) Data Needed to Compile the Indicator:
• Energy use by service/commercial sector.
• Electricity consumption by service/commercial sector.
• Real value added of the sector.
• Built areas or occupied space (sometimes, heated space).
(b) National and International Data Availability and Sources: Data on value
added or GDP in one-digit service sector branches of the International Standard
Industrial Classification (ISIC) system are available for almost every country. More
detailed data exist for Organisation for Economic Co-operation and Development
(OECD)
countries, both from national sources and from the OECD national accounts,
as well as from the OECD’s STAN database.
Energy-use data at the sector-wide level are available for almost all OECD countries
and for most others, but there are some important caveats. First,
one must check the
residential sector data from the same source to determine whether liquid and solid
fuels have been divided between these sectors (service/commercial and residential). In
many of the IEA time series, this division is not made, and
one sector or the other has
all of the liquid or solid fuels. For developing countries, this split is a problem for gas
as well, which is often entirely allocated to either residential use or services rather
than being split. Second, it must be checked whether the service/commercial
sector
contains data from other sectors — for example, agriculture, construction,
street
lighting and even non-energy utilities like water and waste disposal.
Regional data are available from regional organizations such as the Asia Pacific
Energy Research Centre (APERC) and the Organización Latinoamericana de Energía
(OLADE).
