Challenges

In March 1982, St Luke’s opened its Community Centre for the benefit of its existing pensioners and other residents living in the area. The Centre was previously a London School Board primary school and then the Frank Barnes School for the Deaf.

The building is a refurbished four-storey community building of approximately 1,900m² that faced frequent complaints due to overheated and underheated rooms. The centre wanted to give occupants some local control on individual radiator level, without allowing wasteful extremes. They also needed a simple remote monitoring solution without undergoing major renovations. The centre decided to implement a smart heating solution that controls energy use, while improving occupant comfort.

Solution

To address these challenges, the Community Centre partnered with Sontay and installed 25 MClimate Vicki LoRaWAN® Smart Radiator Thermostats in 2025 that were implemented into the Community Centre’s BMS via the Sontay Tower. An additional 18 Vicki devices were later ordered for the remaining common areas of the building, with installation planned for April 2026. This quick retrofit solution was implemented without disrupting the centre’s daily operations.
These smart devices now enable the centre to remotely monitor and control heating on a room-level basis, ensuring a balanced temperature across the premises based on usage trends identified over time with the building management system implemented through the Sontay Tower. Thanks to the device’s manual rotary control, occupants can now adjust the temperature to be more comfortable, while letting the centre set a maximum and minimum level to limit energy waste. At the same time, the device allows the centre to set a precise target temperature in given spaces, like the cookery school, and not allow occupants to override it via the “Child lock” functionality. Finally, the Vicki LoRaWAN® Smart Radiator Thermostat detects open windows and can automatically pause the heating, further optimizing the centre’s energy consumption. The complete solution helps the centre optimize energy consumption thanks to weekly schedules and automatic climate control in accordance with its activities.

By partnering with Sontay and choosing MClimate’s IoT hardware, St Luke’s Community Centre showed that smart, room-level temperature control can be delivered without replacing the existing infrastructure, thus avoiding costly and intrusive renovation works.
