Building Management

Smart Watteo helps residential and tertiary building managers renovate their real estate portfolio with optimal ROI thanks to public aid (CEE bonuses, Anah aid, etc.) so they can reduce their energy and water consumption and save money (50% on energy, 30% on water), improve the comfort of residents/users, enhance their heritage (+4% per energy class gained) and reduce their carbon footprint. With Smart Watteo's digital platform, managers can effectively regulate and monitor energy and water usage in real-time using connected smart sensors. These sensors measure savings, enable remote control, and ensure the smooth operation of heating and water systems by issuing smart alerts in case of anomalies or malfunctions.

The Hospital Center De Soissons, housing 670 beds, stands as a crucial institution in the South East Territory of Picardy, catering to a population of nearly 200,000 individuals. Comprising eight buildings, the hospital complex serves diverse purposes, including medical, nursing, and support services, as well as residential care for the elderly, facilities for medical students, administrative offices, and technical support areas. These buildings contain various types of rooms, including administrative offices, medical examination rooms, storage facilities, cafeterias, corridors, dining areas, and classrooms, among others. All of them required central monitoring and control of the indoor climate on a room-by-room basis as the lack of individual approach led to substantial energy expenses and building inefficiency heating rooms equally, even when unoccupied. Radiator temperature adjustments were made only manually resulting in overheating and opening the window. The lack of real-time facility data made it difficult to optimize the temperature according to the occupants' needs. The building management staff was searching for a solution that did not require time-intensive and expensive renovations as they could not stop operations.



In order to decrease energy expenses and maintain a comfortable indoor climate for the occupants, the Hospital Center De Soissons required precise data and control over each building. With the installation of 420 Vicki LoRaWAN® Smart Radiator Thermostats, 13 automated control regulators, and 48 LoRaWAN temperature and humidity sensors, alongside Smart Watteo's digital platform, they managed to monitor, analyze and control their buildings' energy consumption. By adjusting properties’ temperatures on a room-by-room basis and ensuring optimal energy use, the hospital management achieved significant cost savings of 30% in the first heating season. The customizable scheduling feature of Vicki Smart Radiator Thermostats proved especially beneficial in areas like administrative buildings, cafeterias, and dining rooms, where heating was only required during working hours. Furthermore, the open-window detection function contributed to additional cost reductions by preventing unnecessary energy waste. Vicki's compatibility with standard radiators facilitated easy installation across the various building types in the hospital complex. The open-source, no vendor locked-in settings of the devices ensured seamless integration with the Smart Watteo's digital platform allowing combination with third-party sensors.   

The complete smart building solution allowed managers to gain access to historical and real-time building data, empowering them to analyze and enhance building efficiency, reduce costs while tracking sustainability objectives.
