Case Study: Going Green and Saving Green in a Municipal Office Building

Client

Faced with rising energy costs and outdated heating controls, a public office building deployed smart thermostatic radiator valves and environmental sensors. The goal was simple: improve comfort, reduce waste, and avoid expensive system overhauls.

Challenges

The building served as both an administrative office and a field service hub, with high foot traffic and irregular occupancy. Without centralized control, radiators were often left on in empty rooms, running overnight, or heating at excessive temperatures. This led to high utility bills, energy waste, and inconsistent indoor conditions.

Solution

The installation included 21 LoRaWAN® Smart Radiator Thermostats, each protected with anti-vandal cases, alongside 4 humidity and temperature sensors and a CO₂ sensor. The system allowed for remote monitoring and real-time control over the building’s heating and indoor climate. It also enabled custom scheduling for each room or zone, aligning heating with actual occupancy. The solution required no disruptive renovations and was installed within 24 hours. With detailed usage insights and automation, the municipality could reduce unnecessary heating, improve comfort, and introduce more sustainable practices.

Results

The project delivered a 31.25% reduction in heating costs and a significantly improved working environment. Return on investment (ROI) was achieved in just 14 months, thanks to the efficiency gains from occupancy-based scheduling. The long-lasting battery life of the devices—up to 10 years—ensures minimal maintenance over the coming decade, while the real-time environmental data supports continued optimization. The initiative also made a positive impact on the building’s carbon footprint.
