In this paper we present the work achieved to build the FIEMSER Data Manager.We detail the methodology used to elaborate the Data Model, starting from the analysis of the various data exchanged in the use cases.We present how these data have been categorized and structured in a global data model, interoperable with standard BIM representations like IFC or gbXML. Finally we illustrate how this data model underlies the implementation of the Data Manager, which interfaces with other system components through Restful web services. The FIEMSER system will be tested in two locations to assess the energy savings compared to more traditional energy control systems. %~
