Odyssee: Energy Efficiency Database

For nearly two decades, Enerdata has been the technical coordinator of the Odyssee Project, aimed at benchmarking the energy efficiency performance of EU member countries.

Odyssee provides unique energy efficiency indicators as well as detailed energy consumption data by end use through the industry, residential, transport and services sectors, as well as underlying drivers. Whether you are a policy maker, a researcher, an investor, or a banker, find the way to the greenest usages, sectors and industrial branches across countries.

What is the energy consumption by end-uses (space heating, lighting, electricity appliances, etc.) of households in a given country? What is the vehicle stock? What are the energy savings of a specific sector?

A top-down approach to capture energy savings in Europe

• The Odyssee Project has developed an index to measure energy efficiency progress by country and sector as well as for all final consumers
• ODEX by sector combines unit consumption indicators by sub-sector (or end-use or mode of transport), into one index for the sector by weighing each sub-sector index by its share in the sector’s energy consumption
• Unit consumption index by sub-sector can use different physical units to be as close as possible to energy efficiency evaluation: toe/m², kWh/appliance, toe/ton, litre/100 km
• ODEX is presently calculated on the basis of 26 sub-sectors (seven modes in transport, nine end-uses/equipment for households, and 10 branches in industry)
• ODEX can also be expressed in terms of volume of energy saving
