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.
