Abstract: This paper introduces a novel visualization tool that uses visual analytics to present energy data estimated by equipment-level virtual meters and allows users to interact with the visualization to gain insights that can be used to improve building energy performance. The features of the visualization tool are demonstrated through a case study that utilizes data collected from a commercial building in Ottawa, Canada. The data are used to train inverse greybox models, and model parameters are fed into the visualization tool to create virtual meters that estimate the heat added or extracted by an air handling unit and the heat added by zone-level radiant heaters. Users can interact with the visualization via interactive processes that enable them to select, filter, and/or explore the virtual metered energy to assist in building operational decisions. The potential of the visualization tool for improving building energy performance and assisting decision-making processes is discussed through illustrative examples.
