D5 - FIEMSER Data Model

This deliverable, produced at month 9 of the Fiemser project (http://www.fiemser.eu), results from the work achieved in task T1.4 "FIEMSER Data Model Definition" which is part of WP1 dealing with system specifications. The main goal of this Work Package is to provide FIEMSER project with specific requirements and to define the different components through a joint design methodology that involves the overall architecture model as well as components interfaces and communication protocols analysis. It provides a Technical Specification for the next work packages. The main objective of task T1.4 is to complement the design of the architecture developed in task T1.3 with the modelling of the information coming from outside (weather conditions, electricity prices, gas prices), the data to be exchanged between the main components of the FIEMSER system, and the data to be exchanged with loads, generators and storage devices. The followed methodology consisted in (1) categorizing the data handled in Use Cases (see deliverable D3), (2) modelling data in each identified category and, (3) merging the resulting sub-models into a holistic data model for FIEMSER. Complementary, an analysis of the state-of-the-art has been made through a review of ongoing R&D projects on ICT4EE in Buildings with a focus on data modelling, and available standards in building information modelling (IFC, gbXML) have been examined, in order to build our modelling activity on the most relevant results of related research work and existing standards for information modelling. It is planned that this modelling work will be disseminated towards the relevant standardisation bodies (as a proposal for possible standard extension), and communicated to analysed R&D projects to get their feedback on the appropriateness of the model to their own concerns.
