Abstract

Scope: This paper provides recommendations for data-driven interfaces for advanced building operations and maintenance developed through ASHRAE Research Project 1633. Informing operations and maintenance with data-driven information is critical to achieve high-performance buildings. Substantial guidance illustrating how to measure and convey building performance information has already been created, such as in ASHRAE Guideline 13-2015 (ASHRAE 2015) and Performance Measurement Protocols for Commercial Buildings (ASHRAE 2010). RP-1633 focused attention on operations and maintenance stakeholders, including control technicians, HVAC technicians, service providers, commissioning agents, and facility managers by conducting literature reviews, commercial interface reviews, and stakeholder interviews 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 floor plans; as time-series line charts; in calendar plots, bar charts, and pie charts; and relative to expected performance, past performance, orarelevantbenchmark.Wewillpresentfeedbackfrom operationsandmaintenancepersonnelandourresearch about the types of metrics, at each scale, in which visualization format is most useful for advanced operations and maintenance.
