Disturbance-Adaptive Data-Driven Predictive Control: Trading Comfort Violations for Savings in Building Climate Control

Model Predictive Control (MPC) has demonstrated significant potential in improving energy efficiency in building climate control, outperforming traditional controllers commonly used in modern building management systems. Among MPC variants, data-driven predictive control (DPC) offers the advantage of modeling building dynamics directly from data, thereby substantially reducing commissioning efforts. However, inevitable model uncertainties and measurement noise can result in comfort violations, even with dedicated MPC setups. This work introduces a disturbance-adaptive DPC (DAD-DPC) framework designed to ensure asymptotic satisfaction of predefined violation bounds under sufficient conditions. The framework employs a fully data-driven pipeline based on Willems' Fundamental Lemma and conformal prediction for application in building climate control. The proposed DAD-DPC framework was validated using four building cases, leveraging a high-fidelity simulation platform, BOPTEST, and an actual building testbed, Polydome. For a 5% violation bound, the framework achieved energy consumption increases of 2.82%, 2.24%, 3.75%, and 5.09% while reducing comfort violations by 77.62%, 79.51%, 73.26%, and 39.76%, respectively, compared to other controller configurations. These results demonstrate the framework's ability to effectively balance energy consumption and comfort violations, offering a practical solution for building climate control applications.
