• Title: Zero-Shot Building Control
• Authors: Scott R. Jeen, Jonathan M. Cullen
• Abstract summary: Control via Reinforcement Learning (RL) has been shown to significantly improve building energy efficiency. Existing solutions require pre-training in simulators that are prohibitively expensive to obtain for every building in the world. We show it is possible to perform safe, zero-shot control of buildings by combining ideas from system identification and model-based RL.

• Abstract: Heating and cooling systems in buildings account for 31% of global energy use, much of which are regulated by Rule Based Controllers (RBCs) that neither maximise energy efficiency nor minimise emissions by interacting optimally with the grid. Control via Reinforcement Learning (RL) has been shown to significantly improve building energy efficiency, but existing solutions require pre-training in simulators that are prohibitively expensive to obtain for every building in the world. In response, we show it is possible to perform safe, zero-shot control of buildings by combining ideas from system identification and model-based RL. We call this combination PEARL (Probabilistic Emission-Abating Reinforcement Learning) and show it reduces emissions without pre-training, needing only a three hour commissioning period. In experiments across three varied building energy simulations, we show PEARL outperforms an existing RBC once, and popular RL baselines in all cases, reducing building emissions by as much as 31% whilst maintaining thermal comfort.

  The identification of effective control strategies to suppress or enhance the convective heat exchange under fixed external thermal gradients is an outstanding fundamental and technological issue.
