EDVE: An Energy Diagnosis Visualization Environment

Abstract

In this paper we describe the motivations, development and results of EDVE: the Energy Diagnosis Visualization Environment that helps to quickly visualize faults and anomalies in energy consumption at the whole building level. EDVE relies in visual comparisons against predicted benchmarks using calibrated building models plus a set of predefined performance metrics. In this paper EDVEs development process is explained and a framework to evaluate web technologies prior its adoption is proposed. The underlying methodology of the tool is also described alongside an example of use. In this example, a data set generated by a modelling software where different faults have been forced is visualized. The effectiveness of different benchmark metrics to assist on fault analysis and diagnosis tasks is discussed. Finally, potential shortcomings and challenges ahead are outlined.
