Deep Reinforcement Learning for Low-Level HVAC Control in Multi-Zone Buildings

Imagine a smart autopilot for a building’s heating and cooling system. Instead of fixed rules set by engineers, the system learns by trial and error how to adjust valves, fans, and temperatures in each room to keep people comfortable while using as little energy as possible. This research compares that learning-based autopilot to today’s best-practice rulebook (ASHRAE G36).

Executive Brief

Business Problem Solved

Traditional HVAC control in complex, multi-zone buildings relies on static rule sequences (like ASHRAE G36) that can’t fully adapt to changing usage patterns, weather, and occupancy, leading to higher energy consumption and sometimes poor comfort. The work addresses how deep reinforcement learning can replace or augment these rule-based controls at the low level to improve energy efficiency and comfort simultaneously.

Value Drivers

Energy cost reduction through more efficient HVAC operationImproved occupant comfort via adaptive control of multiple zonesReduced need for manual re-tuning of control sequences when building usage changesPotential reduction in carbon footprint for large building portfoliosDifferentiation for smart-building / green-building certifications

Strategic Moat

If deployed commercially, the moat would come from proprietary training data and control policies tuned to specific building types and equipment; tight integration with BMS vendors; and validation against standards like ASHRAE G36 that makes the approach credible for engineers and regulators.

Differentiation Factor

Unlike generic building automation, this work targets low-level HVAC actuation in multi-zone settings using deep reinforcement learning and directly benchmarks performance against ASHRAE G36 control sequences, which is the current reference standard in commercial building controls.
