Summary

This paper proposes a two-stage personalized thermal comfort system that integrates multimodal physiological and environmental sensing with reinforcement learning for adaptive building control. It aims to move beyond static setpoints to cater to individual occupant thermal preferences.

Conventional Heating, Ventilation, and Air Conditioning (HVAC) systems typically rely on static temperature setpoints and generalized comfort models, which often fail to account for individual physiological differences. This leads to suboptimal thermal comfort for occupants and inefficient energy use. This research introduces a novel, two-stage approach to achieve personalized thermal comfort within buildings. The proposed system integrates multimodal sensing, combining physiological data from occupants with environmental data from the building. This rich data stream feeds into a reinforcement learning (RL) based decision-making engine. The RL agent learns individual thermal preferences over time, moving beyond population-level averages. By continuously adapting to an occupant's unique physiological responses and the surrounding environment, the system can provide more responsive and personalized thermal interventions. This approach promises to enhance occupant well-being while potentially improving the energy efficiency of building control strategies.

Why it matters

For building managers, smart home developers, and HVAC system manufacturers, this research offers a pathway to significantly improve occupant comfort and energy efficiency. Personalized thermal control can lead to higher satisfaction, productivity, and reduced operational costs.

How to implement this in your domain

  1. 1Investigate integrating multimodal physiological sensors (e.g., wearables) with environmental sensors in smart building prototypes.
  2. 2Develop reinforcement learning agents capable of learning individual thermal preferences from sensor data.
  3. 3Design adaptive HVAC control strategies that respond dynamically to personalized thermal comfort predictions.
  4. 4Conduct pilot studies in commercial or residential buildings to evaluate the impact on occupant comfort and energy consumption.
  5. 5Collaborate with building automation companies to explore commercialization opportunities for personalized thermal control systems.
