Implementation of a Humanized Adaptive Baseline Information Technology (HABIT) System for human-centric Mechanical Ventilation and Air Conditioning (MVAC) Control

I&T Solution Implementation of a Humanized Adaptive Baseline Information Technology (HABIT) System for human-centric Mechanical Ventilation and Air Conditioning (MVAC) Control
(REF: S-1922)
Trial Project
Solution Feature
  • The Humanized Adaptive Baseline Information Technology (HABIT) System utilizes occupant feedback to adjust set-point temperatures dynamically, enhancing occupant comfort beyond fixed settings and manual adjustment.
  • Employs Bayesian methods to refine temperature predictions based on real-time complaints.
  • Integrates an IAQ index and complaints to assess air quality, combining health and comfort criteria to determine fresh air quantity.
  • Utilizes IoT-based temperature and IAQ sensors to gather real-time data for responsive adjustments to environmental conditions.
  • Prioritizes occupant comfort and health by incorporating subjective feedback into the control system, fostering a more humanized indoor environment.
Trial Application and Expected Outcome
  • Provide support and technical input on selecting temperature and IAQ sensors during the tendering process. Work with sensor suppliers to install IoT sensors in a designated building for real-time environmental measurement.
  • Collect data on occupant feedback and environmental conditions using a webpage or mobile app. Develop a database on environmental conditions and subjective responses towards the environment.
  • Analyze feedback and sensor data to develop the HABIT control algorithm for temperature set-point and fresh air quantity control.
  • Implement iterative updates based on trial findings, and fine-tune the algorithm to optimize real-world performance with the occupant satisfaction. Involve facility management and occupants in the trial process to gather insights and improve system acceptance and effectiveness.
  • The final set-point temperature shall align with the expected neutral temperature for the specific group of building occupants. Fresh air control shall focus on meeting health standards while also enhancing perceived IAQ levels based on occupant input.
