- AI-supported tools Amazon uses to monitor utility and building system performance in 120 of its sites globally will be expanded to more than 300 facilities by the end of the year, the company said today.
- We’re “innovating with AI to help us find new ways to decarbonize even faster, including inventing new solutions that … make our buildings more energy- and water-efficient,” Chief Sustainability Officer Kara Hurst said in a statement.
- Amazon is using the technology to analyze HVAC operational data and energy consumption, monitor refrigeration units, identify issues like leaks or clogged filters, with the goal of reaching net-zero carbon emissions across its operations by 2040, the company said.
Dive Insight:
The company developed the tools within its Amazon Web Services subsidiary. A tool the company calls FlowMS monitors building water systems and one called Base Building monitors HVAC systems. A third tool is being rolled out to monitor refrigeration systems in more than 150 fulfillment centers worldwide, the company said.
The tools have already helped Amazon reduce water and energy consumption at sites in Scotland, Spain and New York, the company said.
In the Scotland facility, the FlowMS tool helped associates uncover a leak in an underground water line that could have caused up to 9 million gallons in annual water losses, the company said. The tool analyzed the building’s water meter data, saw that it was using more water than expected and alerted engineers, who traced the leak and repaired a faulty valve, the company said.
The Base Building tool leverages Amazon’s SageMaker and Lambda machine learning capabilities to analyze HVAC operational data, energy consumption and local weather data to identify possible system anomalies, the company said.
The tool helped Amazon pinpoint a miscalibrated utility meter at a New York facility that appeared to be using five times more energy than nearby facilities. Separately, Amazon identified a malfunctioning air conditioning unit at a Spanish facility by comparing its actual cooling output in real time to expected performance based on outside weather conditions.
Amazon is also using the Base Building tool at delivery site dock doors to alert employees when doors are left open after trucks load or unload. The goal is to reduce energy loss and potentially achieve “substantial energy savings,” the company said.
The Refrigeration Monitoring tool analyzes fulfillment-center refrigeration units in real time to help maintain ideal temperatures for perishable goods. The tool predicts which system components are involved in a possible anomaly and alerts company associates so they can take action.
At a site in Spain, the refrigeration tool identified a change in the defrost cycle caused by a piece of malfunctioning equipment, preventing “significant food loss and an estimated 1,000 hours of equipment downtime,” the company said.
FlowMS is operational at more than 40 Amazon sites in North America while the refrigeration tool is active at nearly 100 North American sites, an Amazon spokesperson told Facilities Dive.
