  Due to its significant contribution to global energy usage and the associated
greenhouse gas emissions, existing building stock's energy efficiency must
improve. Predictive building control promises to contribute to that by
increasing the efficiency of building operations. Predictive control
complements other means to increase performance such as refurbishments as well
as modernizations of systems. This survey reviews recent works and
contextualizes these with the current state of the art of interrelated topics
in data handling, building automation, distributed control, and semantics. The
comprehensive overview leads to seven research questions guiding future
research directions.
