Accenture Helps Metro de Madrid with an AI-Based Self-Learning Ventilation System

Accenture has helped Metro de Madrid develop and implement a self-learning AI-based ventilation system that mini­mizes energy costs and emissions and ensures high air quali­ty in metro stations and commuters’ comfort.

The artificial intelligence (AI)-based system has enabled Metro de Madrid to reduce its energy costs for ventilation by 25 per cent and cut CO2 emissions by 1,800 tons annually.

Further, Accenture will present the system at this year’s MWC (formerly known as Mobile World Congress) in Barcelona, Feb. 25-28.

The Madrid Metro Ventilation experts worked with Accenture Applied Intelligence to develop a system that took inspiration from an unusual source: the coordinated foraging behavior of a bee colony. The system deploys an optimization algorithm that leverages vast amounts of data to explore every possible combination of air temperature, station architecture, train frequency, passenger load and electricity price throughout the day. The algorithm uses both historic and simulated data, factoring in outside and below-ground temperatures over the next 72 hours. Because the algorithm uses machine learning, the system gets better at predicting the optimal balance for each station on the network over time.

The system also includes a simulation engine and maintenance module, which allows for, among other things, tracking for failures in the fans’ operation. This enables Metro de Madrid to easily monitor and manage energy consump­tion, identify and respond to system deficiencies, and pro­actively conduct equipment maintenance.

“With the help from Accenture, the innovative ventilation system has enabled us to achieve the dual benefits of lower energy costs and a reduced environment impact,” said Isaac Centellas, Head of Engineering and Maintenance Division at Metro de Madrid. “Ensuring the comfort of our passengers while being highly energy-efficient and environmentally friendly is a true win-win outcome.” 

Isabel Fernández, managing director for Accenture Applied Intelligence in Spain, added, “Our self-learning ventilation system shows how organizations and society can benefit from intelligent technologies. It’s an important milestone in our work for Metro de Madrid, and we’re excited to present it to the public at this year’s MWC, where applied AI will play a bigger role than ever.”
