Case Study: Lowering Energy Consumption for a Major Financial Institution

Client

A major bank sought to modernize heating across its national office portfolio, focusing on outdated buildings in smaller cities. With rising energy costs and remote work policies in place, the goal was to reduce consumption, enable remote control, and support ESG reporting—all while meeting strict data privacy standards.

Challenges

In 2021, the bank began modernizing its building infrastructure with a focus on energy savings and operational sustainability. Heating systems in many of their sites were outdated, offering little control or visibility into usage patterns. The goal was to implement a system that could manage heating remotely, adapt to room occupancy, and offer granular insights at the room, floor, and building levels. Security and privacy were non-negotiable due to the sensitive nature of the bank’s operations.

Solution

Over 1,000 LoRaWAN® Smart Radiator Thermostats and 150+ temperature and humidity sensors were deployed. Tenants could control heating locally or via an app, while facility managers could monitor and schedule heating remotely. A secure private LoRaWAN® network ensured full compliance with the bank’s privacy requirements. The solution was installed and live within one week.

Results

In the first year, the bank achieved a 45% reduction in heating energy use and cut maintenance costs by over 50%. The system paid for itself within the first year of use and continues to support sustainable operations, comfort, and employee engagement.
