Running a spa in an energy crisis? How the Green Pearls® partners meet the challenge

Energy efficiency. Energy consumption. Operating costs. You hear these terms everywhere at the moment. Entrepreneurs and private individuals are looking ahead to the coming winter heating season, sometimes with trepidation.

Green Pearls® hoteliers are also facing a new challenge. The rooms should be warm and in the spa area guests should be able to forget their own worries for a moment. At the same time, in the face of the climate crisis and rising energy costs, rethinking and action are urgently needed.

Sustainable energy concepts and creative solutions

The hotel sector contributes about 4% to the current consumption of energy resources. Savings are an inevitable step here as well. For our Green Pearls® partners, sustainable business in harmony with nature is in their DNA. In view of the current situation, they are implementing more sustainable energy concepts and creative solutions as a matter of course.

Even though the hotel sector represents only a small share of energy resources consumption compared to the manufacturing industry, it has a high potential for savings, especially in the spa area. Here, saunas, swimming pools and steam baths are constantly heated. The room temperature is higher and the lights burn longer than in the rooms. The Green Pearls® partners are aware of the high energy consumption, so they have emphasised energy-efficient concepts within their sustainability strategies from the very beginning. For the coming winter, almost all of them are planning to further adapt to the gas shortage and the current situation.

Book Spa areas exclusively and save energy

Under the motto "Weihrerhof goes green", a sauna at the Hotel Weihrerhof on the Ritten already remained unused during the summer. The Pichler family had decided to do this due to the high summer temperatures. And in winter the sauna times are shortened and they only run when they are actually being used.

The Hotel Bella Vista Zermatt has taken a similar approach. In summer, it opened the spa area only on request, thus reducing electricity consumption. For the upcoming winter, they are planning to reduce the spa hours or to start up only one of the two saunas. With a wealth of experience in the short-term, flexible implementation of new measures from the Corona crisis, the Bella Vista is optimistic about the upcoming winter season.

The Shepherd's Cart sauna at Hotel Okelmann's in Warpe, Lower Saxony, is also only heated when guests book it in advance. This efficiently conserves resources. The hotel's hot tub must also be booked individually in advance. Only then is it heated. Not with gas, however, but with dead wood from the hotel's own forest area.

Instead of a shepherd's cart, guests at the lifestyle hotel SAND on the Baltic Sea coast can expect a rooftop sauna with a view over the surrounding countryside. This sauna is only heated by prior arrangement and can then be used exclusively, and not only since the impending energy crisis. In addition to the exclusive operation of the sauna, the SAND also ensured optimal insulation during the construction of the building in 2017 by installing Cero sliding doors, among other things. There are also plans to heat and cool the Sunny Side building with geothermal energy and to build a photovoltaic system.

Customised Building Technology

At Hotel Das Rübezahl in Bavaria, nothing stands in the way of hotel operations, even in the event of a gas shortage. The pool and outdoor pool are already heated exclusively with waste heat from the hotel's own cold storage facilities. The regulation of the sauna, among other things, is adjusted manually by timers. In the future, an automatic system will adjust such energy-intensive facilities to the individual outdoor temperature and usage at specific times.

One such automatic system is Spa Control, which has been in use at Gut Nisdorf for several years. With the help of motion detectors, Spa Control only switches on the lights and sauna when someone is in the corresponding area. It was important to the team of the estate that the guests can use the wellness area in the afternoon without restrictions and without prior appointment. Nevertheless, energy should not be consumed unnecessarily.

Innovative and sustainable concepts

With modern and energy-saving technology, the Rehlegg also sets an example in the field of energy efficiency. The outdoor pool receives its heat via a solar thermal system, and already 50% of the electricity demand can be covered from the hotel's own production. In order to be prepared for the future, the Rehlegg is planning a photovoltaic system.

Electricity from the hotel's own solar system, two of its own combined heat and power plants for energy and heat - at the HUBERTUS Mountain Refugio, the energy concept is designed for sustainability from front to back. Of course, this also includes the newly built Mountain Spring Spa.

Underneath the plunge pool in the sauna area and the natural bathing lake runs a collector field with cooling liquid. The coolness recovered there makes it possible to lower the floors of the saunas from up to 60 °C to comfortable temperatures. In winter, this system ensures that the plunge pool does not have to be heated up separately and does not freeze over.

Thanks to the modern shading system in the HUBERTUS, blinds darken the hotel rooms and the spa area under certain conditions. In summer, this means that the spa needs to be cooled almost 30 % less.
 

Water from sustainable sources

The view of the HUBERTUS is characterised by the water that surrounds it in the form of an infinity pool, the diving pool and the natural bathing lake. The water used for this comes from the hotel's own mountain spring. This is also where the hotel gets the water for the gardens and the toilets in the spa area. The waste water is transferred via the regional sewage treatment plant in the valley to relieve the Balderschwang spring.

The Green Pearls® partners are looking ahead to winter with creative and innovative ideas. Guests can rest assured that everything is being done to reduce energy consumption and, at the same time, provide them with a relaxing stay.
