BEMServer: An Open Source Platform for Building Energy Performance Management

Abstract: In the era of new technologies and with the growing need for reliable ecological energy supplies, researchers eyes are diverted towards reducing the energy consumption of buildings which becomes a major concern that requires a variety of actors being involved (e.g., building owners, energy/facility managers, occupants, data scientist), who have different expertise and need to use different tools This paper introduces BEMServer, an open source Build- ing Energy Management system solution built to ease the integration of data analytic and visualization services into building and energy domain applications. It handles heterogeneous data in a transparent way by providing a clear and unambiguous semantic representation of the modeled resources. To do so, BEMServer integrates the OntoH2G formal ontology at its core. The architecture of BEM- Server, the design and use of OntoH2G in the solution, as well as the suitability of BEMServer as a middleware in the H2020 project Hit2Gap are described
