To address this challenge, this paper investigates and explores Interpretable Machine Learning (IML), a branch of Machine Learning (ML) that enhances transparency and understanding of models and their inferences, to improve the credibility of MLC and its industrial application in HVAC systems. Specifically, we developed an innovative framework that combines the principles of Shapley values and the incontext learning feature of Large Language Models (LLMs) . While the Shapley values are instrumental in dissecting the contributions of various features in ML models, LLM provides an in-depth understanding of thenon-data-driven or rule-based elements in MLC; combining them, LLM further packages these insights into a coherent, human-understandable narrative. The paper presents a case study to demonstrate the feasibility of the developed IML framework for model predictive control-based precooling under demand response events in a virtual testbed. The results indicate that the developed framework generates and explains the control signals in accordance with the rule-based rationale.  \nKeywords  \nBuilding control, machine learning control, interpretable machine learning, Shapley value, large language model  \n1 Introduction  \nBuilding operations account for approximately 30% of the world's total energy consumption and 26% of global greenhouse gas emissions (EIA 2023) . As predicted by the Department of Energy [1], the US needs advanced technologies to achieve substantial decarbonization and transition to clean energy by 2050, considering the projected increases in both population and business activities. In this endeavor, the control and optimization of building operations emerge as a pivotal aspect. The precise control and adjustment of various building systems based on real-time data and conditions helps to eliminate wasteful energy consumption, prevent system conflicts, and ensure that energy-consuming equipment operates at optimal levels [2] .  \nGiven the surge in building automation systems adoption and the influx of a large amount of data, the industry's pivot to machine learning control (MLC) [3, 4] has become imperative. MLC has the capabilities to handle complex nonlinear systems where traditional linear control methods fall short [5, 6] . Machine Learning Control (MLC) applications in building energy systems have demonstrated great potential and can be categorized into different categories based on their control strategies [4] . Machine Learning-based Model Predictive Control (MLbased MPC) utilizes ML models for system identification. For instance, Cole et al. [7] employed a neural network (NN) to predict building energy load, and Kim et al. [8] used NN to forecast indoor air temperature, energy consumption, and daylight illuminance. In contrast, ML-based model-free control, such as Reinforcement Learning (RL), directly learns control actions from environmental interactions. Examples include Wei et al.
