Hong Kong’s airport has become the first in the world to adjust its air conditioning based on real-time weather data, cutting down its yearly energy consumption by the amount needed to power 1,200 households over the same period.

The new Predictive Control System for Air Conditioning, jointly developed with electricity utility CLP Power, uses machine learning and real-time data about inbound flights and passenger flow alongside weather information provided by the Hong Kong Observatory to predict and regulate the indoor temperature of Terminal 1 so it stays between 24-25.5° Celsius.
