LLMs for HVAC Control
Free while signed in. Answers cite the passages they came from.

Microsoft applies LLMs to industrial control tasks (HVAC for buildings), comparing against RL baselines.
Demonstration selection: Develops a recipe for selecting demonstrations and generating high-performing prompts for industrial control tasks.
GPT-4 ≈ RL: GPT-4 performs comparably to specialized RL methods on HVAC control, despite being a general-purpose model.
Lower technical debt: Uses dramatically fewer samples and avoids the operational complexity of training and maintaining a dedicated RL policy.
Practical implication: Suggests LLMs can substitute for RL in many control tasks where sample efficiency and maintenance matter more than peak performance.
