1. Smart Meters Using LoRaWAN
Smart meters powered by LoRaWAN technology bring a new level of efficiency to energy monitoring and cost management. These meters enable real-time tracking of energy usage while consuming minimal power, making them an excellent choice for industrial and commercial settings. This constant data flow supports real-time energy management, improving overall operational efficiency.
One of the standout features is the ability of a single LoRaWAN gateway to connect with battery-powered sensors located as far as 10 miles away. This even includes hard-to-reach places like basements or underground facilities. These sensors transmit data to a remote module, ensuring consistent monitoring – even during network disruptions.
"LoRaWAN allows similar remote reading as we are already using (Ethernet, GSM). However, the key factor to LoRaWAN use is the independence of external power supplies. This means that the readings are documented to the remote reading module, which guarantees almost 100% accessibility to data, even when there are alerts in the network."

Fortum Tartu’s implementation highlights the versatility of LoRaWAN technology. By integrating LoRaWAN modules with Kamstrup systems, they’ve expanded monitoring capabilities beyond energy. Their setup also tracks temperature, capacity, and pressure, showcasing the broader applications of this technology.
Looking at the bigger picture, market forecasts predicted 165.5 million smart meter installations by 2020, alongside a projected 37% increase in global energy demand by 2040. The absence of GSM fees further adds to the cost-effectiveness of LoRaWAN systems. Features like bi-directional communication and precise localization enhance the system’s reliability, making it a strong tool for managing energy consumption effectively.
To maximize the benefits of these smart meters, it’s essential to position them strategically throughout facilities, particularly in areas with high energy usage or around critical equipment. Regularly reviewing the collected data can uncover additional opportunities to improve energy efficiency and reduce costs.
2. Equipment Maintenance Monitoring
Keeping equipment in top condition not only ensures smooth operations but also helps cut down on energy costs. Using IoT sensors for maintenance monitoring is a smart way to avoid wasting energy and prevent unexpected breakdowns. Predictive maintenance, in particular, can save money while improving energy efficiency.
Industrial machinery accounts for as much as 70% of the world’s electricity usage, often running below peak efficiency. IoT sensors can monitor key factors like temperature, vibration, and electrical currents in real time. This means potential problems can be spotted early, well before they lead to costly failures.
Take Rolls-Royce, for example. They’ve adopted digital twin technology to monitor their engines. By creating virtual replicas of each engine using advanced sensors, they’ve managed to extend the time between maintenance intervals by up to 50%. On top of that, they’ve reduced the need for spare parts and minimized aircraft downtime. It’s a clear example of how digital twins can revolutionize asset management.
Another success story is Newmont Corporation’s Eleonore mine. Partnering with Howden, they implemented a ventilation-on-demand system with 30 monitoring stations equipped with flow and gas sensors. RFID tags track the locations of workers and vehicles. The result? A 50% reduction in costs for underground ventilation and a 73% decrease for surface ventilation.
Aramco also showcases the power of real-time monitoring. They use edge-based computer vision systems with high-bandwidth cameras to detect equipment issues instantly. This setup allows them to act quickly and prevent failures before they happen.
One company with a fleet of 500 machines saved around $700,000 annually by adopting IoT-based maintenance strategies. These examples highlight how data-driven approaches to maintenance can lead to substantial financial and operational benefits.
To make the most of maintenance monitoring, organizations should consider these key strategies:

These practices demonstrate how leveraging technology can transform maintenance into a tool for both reliability and efficiency.
3. Smart HVAC Controls
After ensuring proper equipment maintenance, many businesses are now adopting smart HVAC controls to cut down on energy expenses even further.
HVAC systems account for more than a third of energy consumption in buildings worldwide. With the help of IoT technology, smart HVAC controls are changing the game by improving how heating, ventilation, and air conditioning systems operate, leading to noticeable cost reductions.
Traditional HVAC setups often waste energy by heating or cooling spaces that aren’t in use. In fact, over half of office energy consumption happens during off-hours. Smart HVAC controls tackle this issue by using real-time occupancy data and predictive analytics to fine-tune operations and minimize unnecessary energy use.
For example, in January 2025, a U.S. food processing plant implemented smart HVAC controls and saw a 30% drop in energy consumption while also enhancing product consistency. Similarly, a pharmaceutical facility in Europe adopted IoT-enabled HVAC controls and reduced its energy usage by 28% within the first year.
What makes smart HVAC controls so effective? They can:
- Adjust heating and cooling based on real-time occupancy
- Predict temperature needs using advanced analytics
- Maintain a balance between energy efficiency and air quality
- Detect potential problems before they escalate into system failures
One study demonstrated that an IoT-enabled controller reduced fan energy consumption by 51.4%, all while meeting ASHRAE standards. On average, these systems deliver energy savings of 20–30% in industrial environments.
To get the most out of smart HVAC controls, consider using occupancy sensors, setting automated temperature adjustments, integrating the system with other building controls, and regularly reviewing performance data. By combining IoT sensors, machine learning, and automated controls, businesses can significantly lower energy costs while maintaining comfortable and efficient indoor environments.
