Reducing the energy footprint of infrastructure buildings by unlocking synergies between available building automation, energy management, and building information modelling systems


Abstract

The fundamentals of a novel approach towards the management of energy for heating, ventilation, and air conditioning (HVAC) systems of large infrastructure buildings are presented. One of the key concepts of this approach is the integration of existing and retrofitted information and communication (ICT) systems for building management by using an innovative software solution which will be elaborated in detail in this paper. Hence, the authors introduce the modular and extensible software Energy Control and Optimisation Service Platform ECOService which is currently being developed within CAMPUS21, a project funded under the Framework Programme for Research and Technological Development FP7 of the European Union. ECOService is a flexible and versatile software platform developed in JAVA and OSGi that allows tight and easy integration of existing building ICT systems with novel software components for controlling, managing, and balancing energy usage. In principle, ECOService consists of three layers: (1) the data layer DL, (2) the middleware MW, and (3) the application layer AL. The DL allows access to and linking of various building automation control systems (BACSs) and building energy management systems (BEMSs). In order to be able to also include structural information about a building, the DL can connect to an existing building information model (BIM) server as well. Thus, by accessing the DL, the MW can connect to all ICT systems in an asset to retrieve, merge, and evaluate sensor data and metered values describing the asset’s state and to store this information in structured databases. Finally, there will be the AL on top of the MW that will continuously monitor energy consumption as well as compute a multitude of other key performance indicators (KPIs), such as efficiency, CO2 emissions, humidity, or air quality. The overall purpose of AL will be to balance the energy taken from the grid, local microgeneration, and local energy storage in an optimal manner. To demonstrate the viability of the presented approach, ECOService will be installed in three demonstration buildings. To allow maximum flexibility in the deployment of ECOService, a distributed approach is followed. This design choice also allows a deployment in a cloud environment. It needs to be noted that the present paper introduces the high-level architecture of the ECOService platform (i.e. the middleware layer) whereas the detailed presentation of the algorithms of the application layer will be addressed in other papers yet to be published.
