Open Dynamic System

for Holistic energy Management of the dynamics of energy supply, demand and storage in urban areas


The Odysseus Energy Ontology related to the dEPC (dynamic Energy Profile Card): a method enabling the functional and technical description of a neighbourhood covering both static and dynamic energy-related information (properties that are persistent in time and properties that change over time).

The Odysseus consortium opts for "Creative Commons" solution to make the Energy Ontology method available to the market and to interested stakeholders in the building, installation and energy domain.

This approach allows the Odysseus Consortium to keep the authorship of the work and at the same time offers good chances for results adoption and development in the domain. Its dissemination also supports the request on the consultancy services as most of the individual partners have underlined in their individual exploitation strategy.

The Odysseus dynamic Energy Profile Card (dEPC) Ontology  (or the Odysseus “Energy Ontology” in short) is an advanced open semantic information structure covering a wide variety of information types relevant for improved (fossil) energy-efficiency and CO2 reduction in city’s neighbourhoods. The ontology covers entities like buildings where people perform activities; but also street lighting sections, windmill parks, solar parks etc., all under the required indoor/outdoor climate conditions.

Information aspects distinguished are:

  1. Energy: roles, like producing, consuming, storing, transforming, switching & transporting energy, played by matter;
  2. Matter: physical Devices, like sensors, measuring conditions; meters, measuring (energy and material) flows; and infusors and extractors like the light systems and radiators, that condition the Spaces;
  3. Space: conditioned areas like building spaces in buildings, but also areas in windmill parks and solar parks. Especially relevant are local device spaces like a gas boiler grouping devices and a carrier that together convert energy from one form to another. Besides these infusors/extractors all these spaces are typically also directly or indirectly influenced by external influences like their boundaries and the climate behind those boundaries.
