Case Study: Enabling Indoor Climate Smart Solutions in Five Hotel Buildings

Client

A hotel was facing high energy costs and relying on an outdated oil-based heating system spread across five separate buildings. With no room-level temperature control or access to data, achieving operational efficiency and comfort was a constant challenge.

Challenges

The hotel’s aging heating infrastructure offered no centralized control or data access. Radiators operated inefficiently, and staff had to make manual adjustments without insight into room occupancy or conditions. This led to frequent energy waste, especially in vacant rooms, and hindered the ability to maintain consistent indoor comfort. The hotel needed a scalable, minimally disruptive retrofit solution that would deliver quick results without requiring major renovations.

Solution

To modernize the system, the property installed air-to-water heat pumps alongside more than 100 LoRaWAN® Smart Radiator Thermostats across guest rooms and common areas. These devices allowed for precise, room-by-room temperature control, along with open-window detection and customizable heating schedules to prevent unnecessary energy use.

A wireless thermostat was also installed in the dining area to act as a centralized hub for managing multiple radiators. The system provided real-time climate data and remote access, empowering staff to make smarter, faster decisions around heating and energy usage.

Results

The retrofit significantly enhanced the hotel's energy efficiency without the need for extensive construction. Oil consumption was reduced by over 80%, and electricity use for heating dropped as well. By the end of the first heating season, the hotel recorded energy savings of up to 30%.

In addition to cutting costs, the system improved indoor comfort for guests and streamlined daily operations for staff—demonstrating how smart technology can deliver immediate and impactful benefits even in legacy buildings.
