LoRaWAN Digital Energy-Saving Retrofit Solutions for Commercial Buildings

LoRa/LoRaWan Wiring-Free Retrofit Solutions

Under the "Dual Carbon" policy and the trend of smart buildings, traditional energy management methods can no longer meet the needs of enterprises and institutions. Based on LoRa and LoRaWAN technology, we have upgraded the communication of controllers, sensors, and actuators, launching a wiring-free retrofit solution. This solution effectively reduces the renovation costs of old buildings and helps scenarios such as commercial complexes and industrial plants achieve energy consumption monitoring and intelligent management. It improves operational efficiency while saving energy and reducing consumption, providing technical support for the development of green buildings worldwide.

Advantages

Wireless Upgrades, Shortened Deployment Cycle

Based on LoRa / LoRaWAN technology, upgrades can be done directly via wireless communication without major modifications to existing equipment. Deployment can be completed without interrupting operations.
Unified Access, Reduced Complexity

We help customers quickly integrate various devices and protocols—including HVAC, lighting, and sensors—into a single platform through unified access.
Full-Scenario Compatibility, Future-Oriented

From commercial complexes to industrial plants, from office buildings to campuses, our solutions support a wide range of applications and comply with LEED, BREEAM, and China’s green building standards.
