Sunstar Hotel Group: cost-reducing energy optimisation

Sunstar Holding has been relying on Alpiq energy optimisation systems for over 20 years. With measuring devices and peak load optimisation from Alpiq's Xamax brand, this hotel group has so far been able to save a sum of over 1 million Swiss francs.

The Swiss hotel group Sunstar runs a total of ten 4-star hotels in the Swiss mountains and has been using energy optimisation systems from Xamax for over 20 years. At the end of February 2019, hotel facilities in Klosters, Zermatt, Grindelwald, Wengen, Lenzerheide and Saas Fee were equipped with the latest generation of energy data logging devices and visualisation software.

Kitchens, laundries, saunas, gutter trace heating and ramp heating are all incorporated into the system. Energy data is recorded locally at the respective measuring points and clearly displayed with the aid of the visualisation software. Sunstar Holding's technical director is thus provided with transparent analysis, can identify larger electricity loads, and is able to monitor, control and assess energy flows comprehensively.

An optimal system

For enhanced energy management at Sunstar hotels, not only is energy data logged, but expensive load peaks are reduced as well. Thanks to intelligent algorithms, with priorities and dependencies clearly defined and assigned in advance, flexible loads are controlled in such a way that the running of the hotel, and thus the guests' comfort, is not compromised.

With the latest energy optimisation system from Xamax, Sunstar Holding can monitor all hotels with regard to efficiency and cost savings, actively contributing to the energy turnaround and CO2 reduction. "We have been fitting out our hotels with Xamax energy optimisation systems for many years, as their performance and the good support are exemplary. On top of that, they help us to reach our own sustainability targets," says Marco Barbon, Technical Director at Sunstar Holding.
