Modern HVAC systems must process multiple environmental variables that change throughout the day. Indoor temperature variations of 2-3°C can occur within minutes due to solar gain, while relative humidity fluctuations of 15-20% are common as occupancy and weather patterns shift. These rapid changes challenge traditional reactive control approaches that wait for conditions to deviate from setpoints before responding.

The fundamental challenge lies in balancing predictive temperature control with energy efficiency while accounting for the thermal inertia inherent in building systems.

This page brings together solutions from recent research—including deep learning-based predictive modeling, dynamic setpoint modification based on weather forecasts, solar radiation-responsive controls, and presence-detection systems. These and other approaches focus on practical implementation strategies that maintain occupant comfort while optimizing energy consumption.
