Dashboards are increasingly being used in commercial buildings to show building data in an intuitive way to occupants and facility operators. Such dashboards make relevant parties aware of the impact that they have on a building's behavior and enable them to (1) understand the dynamics of building systems and current/historical energy use and, as a result, (2) support reduction in energy use and improvement of operations of such systems. This paper gives an overview of an approach for designing and implementing an e nergy dashboard for a monitored building that includes highly sensed building automation systems and sensors for energy consumption. This project is part of the Energy Efficient Buildings Hub in the Philadelphia Navy Yard. The developed approach incorporates formalization of a taxonomy for building energy dashboards, identification of visualization aids and requirements through a questionnaire, and a prototype implementation. The findings show that effective building energy dashboards should contain query-based and quick-access- based functionalities for showing building energy data through the use of various widgets and user interactions. Such dashboards should also enable decomposing data within spatial and temporal dimensions, interacting with static and dynamic data sources, and providing information about directly measurable energy usage vs. resulting energy use indicators.
