The PLAZA Hotelgroup is a hotel chain with a portfolio of over 50 buildings, totalling more than 6,500 rooms, including a mix of three-star and four-star establishments. Catering to a diverse range of travel needs, they offer comfortable accommodations for both business and leisure travellers. As the wider travel industry their business was affected by the raising energy prices, leading to higher expenses. Manual heating adjustments also resulted in excess heat and energy wasta in unoccupied rooms as well as additional workload for the staff. The PLAZA Hotelgroup was searching for a solution for the challenge and being always on top of the innovation they decided to digitalize the energy management system by partnering with Betterspace to implement the smart energy system better.energy and install Vicki LoRaWAN® Smart Radiator Thermostats.


To solve the problem and stay innovative, they've teamed up with our partner Betterspace to implement the smart energy system better.energy together with Vicki LoRaWAN® Smart Radiator Thermostats into their whole hotel chain. For example, in Best Western Hotel am Kastell in combination with the hotel's PMS system and better.energy, the MClimate's Vicki LoRaWAN® Smart Radiator Thermostats were installed and allowed the control of the heating based on occupancy of the rooms. The shift from traditional valves to Vicki LoRaWAN® Thermostats together with better.energy, effectively stopped rooms from heating when guests had checked out or were yet to check in and prevented unoccupied rooms from cooling down too fast. This, along with temperature limits set on the devices, resulted in a remarkable up to 31% reduction in energy consumption. Vicki's high compatibility with existing radiators made the installation process easy, quick and straightforward without the arising of additional costs for any construction work or cable laying. Once in place, the devices monitored temperature, humidity, and allowed temperature control to be set individually on room-by-room basis. Vicki LoRaWAN® Thermostats are designed to minimize energy consumption when transmitting data to the better.energy system, enabling them to sustain their battery life without requiring maintenance for up to 10 years.
The MClimate Vicki LoRaWAN® Thermostats can be installed virtually in any part of the building, not only guest rooms but also hotel restaurants, meeting rooms, lobby or other public area. Making the whole heating\cooling processes digital together with the long-lasting batteries reduce the workload on the staff and improve the sustainability.
