Objectives of this WP are

  • Specification and implementation of a middleware for energy efficiency that provides an interoperable entry point (interfaces) for integrating dynamically off-the-shelf solutions;
  • Definition of middleware interface to real-time data, DIM info and energy control and saving algorithms;
  • Set up of an intelligent (self-management) sensor network consisting of both off-the-shelf commercial Zigbee-based sensors as well as innovative ultra-low-power sensor nodes that extend the ubiquitous nature of the wireless sensor data collection;
  • Definition of DIMMER ontology.

WP progress


Achievement since the beginning

  • The initial Middleware and DIMMER Platform architecture have been specified.
  •  The heterogeneous data sources (BIM, SIM, GIS, measurement databases) that must be taken into account for realizing a distributed software infrastructure based on a middleware approach to model the whole district have been identified. Based on this several test have been performed to test interoperability and the first prototype for the Database-proxy has been carried out.
  • In order to integrate the STP Wireless Sensor Network (WSN) into the LinkSmart middleware, a first version of a middleware-based software has been developed.
  • Integration of technologies: Coherent Research Energy Management Solution, IREN District Heat Distribution Network Monitoring System, STP Low-power Wireless Sensor Networks.
  • Implementation and initial deployment of main DIMMER middleware components.
  • Integration and interoperability of BIM, GIS and SIM data sources into the DIMMER platform.
  • Implementation and initial deployment of BIM, GIS and SIM services providers to publish and provide district information into the DIMMER platform.
  • The Wireless Sensor Network defined within Task 1.2 was developed and implemented. Preliminary in-field testing provided encouraging results, in terms of data availability, accuracy, autonomy, security and battery lifetime of the sensor nodes. The devices for the Demonstrator in Turin are available and are being installed in the selected buildings.
  • In the area of ontology development, a list of relevant existing ontologies to re-use or specialize in DIMMER has been specified. An assessment framework for evaluation ontology storage and reasoning systems has been developed and used to select the Jena framework for use in DIMMER. A dedicated server for the Semantic Datastore has been provisioned and the Jena framework has been installed on this server. A specific use case in Energy efficiency and benchmarking has been selected to focus the ontology development work on. These results will be integrated into the demonstrator.
