An Approach for HVAC Operational Improvement Using Machine Learning Models to Achieve a Comfortable Indoor Thermal Environment and Air Quality

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
ABSTRACT Optimizing HVAC operation in buildings while maintaining thermal comfort and indoor air quality (IAQ) is a major challenge. This study presents a framework that combines Gaussian Process Regression (GPR) models with an exhaustive search method to improve HVAC operation.
