Real-Time Integration of Building Energy Data
Diogo Anjos, Paulo Carreira, Alexandre P. Francisco · 2014
An Energy Management System (EMS) is a monitoring tool that tracks buildings energy consumption with the purpose of enhancing energy efficiency, by identifying savings opportunities and misuse situations. To achieve this, EMSs collect data flows-data streams-from a network of energy meters and sensors, which are then combined into useful information. Data must be processed in real-time, to support a timely decision making process. Traditionally EMSs use Database Management Systems (DBMSs) to process data, introducing a persistence step that leads to an unacceptable latency on data evaluation and do not properly support many types of time-series queries. This work explores the feasibility of Data Stream Management Systems (DSMSs) to support Energy Management applications, pointing out how to implement an EMS capable of real-time data processing.
