This paper provides recommendations for data-driven interfaces for advanced building operations and maintenance developed through ASHRAE Research Project 1633 (RP1633). Informing operations and maintenance with data-driven information is critical to achieve high performance buildings. Substantial guidance, such as ASHRAE Guideline 13 and Performance Measurement Protocols for Commercial Buildings, has already been created illustrating how to measure and convey building performance information. RP1633 focused attention on operations and maintenance stakeholders, including control technicians, heating ventilation and air conditioning (HVAC) technicians, service providers, commissioning agents, and facility managers by conducting literature reviews, commercial interface reviews, and stakeholder interviews in order to create guidance about data-driven metrics and visualizations that clearly quantify and communicate building operational performance to these stakeholders. The results of this research are presented here, with recommendations to provide metrics and visualizations at multiple scales, including portfolio-wide, whole building, and for specific building areas, systems, and equipment. Metrics span categories related to operating costs, utility consumption, carbon emissions, system performance, controllability, faults, and energy savings. Metrics may be visualized: on maps, system graphics, and in floorplans; as time-series line c harts, in calendar plots, bar charts, and pie charts; and relative to expected performance, past performance or a relevant benchmark. Feedback is presented from operations and maintenance personnel and our research about the types of metrics, at each scale, in which visualization format are most useful for advanced operations and maintenance.
