- Bluetooth technology provides the low-power connectivity needed to collect real-time data and automate decisions
While sustainability initiatives often focus on specific operational challenges, the need for greater insight and the ability to act on real-time information are common requirements across multiple sectors, from commercial lighting to retail to agricultural operations. By providing the low-power connectivity needed for products, assets, equipment, and workflows to become connected, monitored, and optimized, Bluetooth® technology is helping to turn sustainability goals into measurable improvements.
Creating more intelligent and energy-efficient buildings
For commercial buildings, one of the biggest sustainability challenges is reducing energy consumption while maintaining occupant comfort and avoiding costly infrastructure upgrades.
According to Romeo Chen, product manager and product owner at Sunricher, facilities must balance sustainability goals with operational realities. “The central challenge is moving from sustainability targets to measurable operational change,” said Chen. “Facilities must reduce energy use and carbon emissions while controlling retrofit costs, preserving occupant comfort, and avoiding premature replacement of usable assets.”
Bluetooth® technology provides a practical way to modernize existing facilities without extensive rewiring. It connects lighting fixtures, occupancy sensors, daylight sensors, switches, and gateways into a coordinated network that responds dynamically to actual building use.
An example cited by Chen involved upgrading a warehouse or office that uses 0-10V luminaires by adding Bluetooth sensor controllers. Doing so provides occupancy control and daylight harvesting at zone level while avoiding the need for new control cabling. The result is a low-disruption retrofit that reduces unnecessary lighting hours and remains easy to reconfigure.
The greatest opportunity is to scale networked lighting control from a lighting-only system into a shared building-data platform. Occupancy and environmental data can support HVAC optimization, space utilization, demand response, and predictive maintenance.

“Bluetooth® enabled occupancy and daylight sensors support granular, zone-level control,” said Chen. “Lighting can dim or switch off in vacant areas, harvest available daylight, and apply task- or scene-based settings. Reduced operating hours can extend the service life of drivers and luminaires, and using battery-free switches can eliminate battery replacement and associated waste.”
Beyond lighting itself, Chen sees a larger opportunity emerging as building systems become increasingly connected. “The greatest opportunity is to scale networked lighting control from a lighting-only system into a shared building-data platform,” said Chen. “Occupancy and environmental data can support HVAC optimization, space utilization, demand response, and predictive maintenance.”
Reducing waste and improving efficiency across retail operations
Retailers face a different set of sustainability challenges. Frequent price changes, inventory turnover, promotional activities, energy-intensive equipment, and food spoilage all contribute to waste.
Michelle Liang, CTO of Hanshow Technology and chair of the Bluetooth SIG Electronic Shelf Label Working Group, believes sustainable retail operations depend on improving visibility across the entire store environment. “Organizations now need to improve resource efficiency across the complete operational lifecycle,” said Liang. “When products, equipment, people, and workflows can share data, retailers can allocate resources more effectively, reduce environmental impact, and improve business performance at the same time.”
Bluetooth® technology provides a low-power, standardized connectivity layer that supports electronic shelf labels (ESLs), sensors, smart devices, and retail IoT platforms. Those connections help create awareness of inventory conditions, equipment status, and operational activities, enabling faster decision making and more efficient use of resources.
Bluetooth® ESLs can replace large volumes of paper price tags and promotional signage, reducing printing, transportation, replacement, and disposal. According to Liang, one multinational grocery retailer served by Hanshow has reduced paper consumption by approximately 3.53 million A4-equivalent sheets of paper since deploying Bluetooth® ESLs in 2021, corresponding to an estimated reduction of 16.38 tons of CO2 equivalent emissions. Hanshow’s lifecycle assessment also found that a Bluetooth ESL solution integrated with a SaaS platform can reduce carbon emissions by up to 99.25 percent compared with the assessed paper-label process.
Hanshow also partnered with an AI-powered food-waste management platform designed to identify products approaching expiration dates. One of the biggest challenges was minimizing the time store associates spent locating those products quickly enough to take action. “Bluetooth ESL solutions connect product information, shelf locations, and store applications within a unified digital environment, allowing staff to quickly identify and locate items that require attention and helping stores respond more efficiently and reduce unnecessary waste,” said Liang.
Bluetooth connectivity can also enhance additional retail store infrastructures. “Connectivity provides better visibility into the status of lighting, air conditioning, refrigeration, and other store equipment, helping reduce unnecessary use while supporting predictive maintenancesaid Liang. “Looking ahead, I believe the biggest opportunity for Bluetooth® technology in sustainable operations lies in extending low-power connectivity from individual devices to continuous visibility across products, shelves, assets, and workflows.”

Conserving water through smarter agriculture
Unlike commercial buildings and retail environments, sustainability in agriculture often depends on conserving natural resources, with water management among the most critical priorities. For developer and systems architect Víctor Altamirano, inefficient irrigation represented an opportunity to apply Bluetooth® technology to a real-world challenge.
“Globally, agriculture uses more than 70 percent of freshwater,” said Altamirano. “In Mexico, Conagua reports that agriculture takes up about 76 percent of our water and nearly 60 percent of that is lost to leaks, evaporation, or bad practices like flood irrigation. Many physical processes, like agricultural watering, still operate blindly simply because getting reliable power and data to the edge is difficult. Water management is an area where a small technical fix does a lot.”
Wanting to build a system that only watered the crops when they actually needed it, Altamirano and his collaborators developed an automated irrigation system designed to water crops based on actual soil conditions rather than fixed schedules. The system relies on Bluetooth connectivity to link soil-moisture, temperature, and humidity sensors with control valves and a gateway infrastructure.
“We realized pretty quickly that sensor data alone isn’t enough,” said Altamirano. “Knowing the soil is dry is useful, but if a weather API says it’s going to rain in two hours, turning on the sprinklers is a mistake.” Pairing local Bluetooth readings with cloud weather forecasts optimized the system’s efficiency.
Because farm deployments often require large numbers of distributed sensors, the low-power characteristics of Bluetooth technology were essential. Its low power consumption meant that sensor nodes could run on tiny solar panels and batteries while still transmitting data reliably.
The project ultimately demonstrates how Bluetooth low-power connectivity can help organizations monitor environmental conditions, make more informed decisions, and conserve critical resources. “You can’t fix what you can’t measure, and Bluetooth® technology lowers the cost of getting that first measurement,” said Altamirano. “Once you have reliable data, you can aggregate it, run AI analysis to find patterns, and automate decisions. That has a huge impact on actual sustainability.”
A common foundation for sustainable operations
Although lighting, retail, and agriculture operate in different environments, the sustainability outcomes enabled by Bluetooth® technology share common themes, such as greater operational insight, improved resource management, reduced waste, and more intelligent automation.
Across all three sectors, Bluetooth connectivity is helping facilities move from reactive processes to data-driven operations. Whether enabling occupancy-based lighting control in commercial buildings, helping retailers identify near-expired products before they become waste, or allowing farmers to irrigate based on real-time soil conditions, Bluetooth technology provides the low-power foundation needed to collect data, automate actions, and improve efficiency.
