Zermatt's IDE All Weather Snowmaker in Full Swing

By Raúl Revuelta

Zermatt is playing its trump card – the Snowmaker – so that skiers and snowboarders can take to good pistes in the early days of winter as well. The snow machine produces snow regardless of temperature, even above freezing point. And so a good snow base can be laid in early autumn to ensure perfect pistes in winter.

Zermatt Bergbahnen was the first ski resort to order a new kind of artificial snow system: theIDE’s All Weather Snowmaker. Later Pitztal Gletscherbahnen was the second Company to order, following Zermatt’s footsteps, the snowmaker. IDE Technologies is a world leader and pioneer in water desalination, wastewater concentrators and purifiers. The snowmaking technology comes from the mining industry where it is used to cool the goldmines.

CEO Zermatt Bergbahnen Christen Baumann explains how it works: "To put it simply it works like a freezer. The temperature of the surrounding air is irrelevant. In a closed container with a diameter of 3.2m and a height of 10m, water is exposed to a vacuum without any additives. A small portion vaporizes, the remaining water freezes to snow, which is afterwards expelled at a rate of about 40 cubic metres every hour. The snow produced has the consistency of a wet spring snow".

The technology is based on a principle of physics whereby water placed in a vacuum will immediately partly evaporate – without having to reach boiling point. However, the energy needed for evaporation must come from somewhere. In this case, the evaporating water extracts this energy from the remaining water, which is appreciably cooled and thus crystalizes. This crystalized water is thus snow, similar to spring snow, and is used for piste preparation. A transport spiral shoots the snow out to the waiting snowcats. These then distribute the snow in early autumn, as for example between the Theodul Glacier and the summit station of Trockener Steg.

The Snowmaker is used for around 14 days in early autumn for about two to three weeks. Then it is in operation around the clock. The machine is also used systematically in winter and spring, depending on weather and snow conditions.

Kurt Guntli from the Zermatt Bergbahnen AG is the project manager for the huge machine. "Thanks to the Snowmaker we can guarantee the route from the Theodul Glacier to Trockenen Steg from as early as the beginning of October".

2010 Solar Prize for Klein Matterhorn Restaurant

By Raúl Revuelta

The 2010 Solar Prize "confirms our belief that we are on the right track", said Christen Baumann, CEO of Zermatt Bergbahnen AG. With its groundbreaking projects, the company is continuing with the series of pioneering achievements that began in Zermatt more than 200 years ago: as early as 1767, the Geneva naturalist and first person to climb the Klein Matterhorn, Horace Benedict De Saussure, conducted the first experiments on the utilisation of solar energy here. With more than 2,500 hours of sunshine a year the Matterhorn glacier paradise (Klein Matterhorn) in Zermatt with its viewing platform at an altitude of 3,883 metres above sea level is the sunniest place in Switzerland. The solar Restaurantopened by Zermatt Bergbahnen AG on the south flank of the mountain for the 2008/09 winter season produces all the electricity for heating and ventilation using the photovoltaic system built into the facade. Thanks to the optimised design, the building fulfils the requirements of the Minergie-P standard.

 

When developing its infrastructure, Zermatt Bergbahnen AG focuses on three pillars. The first of these is efficiency. Renewable energies make up the second pillar and the third is the use of CO2-free electricity in buildings and to operate the facilities.

The design chosen and the energy concept fulfil the stringent requirements of the Minergie-P standard. The entire electricity consumption for heating and ventilation is produced by the photovoltaic system incorporated in the facade. The ventilation at the rear of the facade is a real innovation. It prevents overheating of the solar panels while enabling the outside air used for the ventilation system to be prewarmed. At the same time, 52 centimetres of heat insulation and triple-glazed windows ensure low energy loss. With the goal of retaining all material cycles within the building to the maximum possible extent, appropriate solutions were found for dealing with the scarce resource water. The building is equipped with its own membrane reactor water treatment plant. This allows purified waste water from the kitchens and washrooms to be recycled for flushing toilets.
The Swiss Solar Agency was founded in 1990 as the Solar91 Working Group and, together with the former energy minister Federal Councilor Adolf Ogi, launched the Swiss Solar Prize. The Prize has been awarded every year since 1991. The European Solar Prize adopted the Swiss model and has been awarded since 1994. The aim of the Swiss Solar Prize is the reduction of Switzerland’s international energy dependency of 82% (2006) by the intensified use of solar power through the use of efficient and economical technologies. The Swiss Solar Prize is awarded annually in the following categories: Persons (persons and legal entities, companies, enterprises etc.), Institutions (municipalities, public institutions, cantons), Buildings (new buildings, refurbishment of buildings), and Plants (Solar thermal collectors, photovoltaic plants, biomass plants).

IDE’s All Weather Snowmaker for Zermatt tested

By Raúl Revuelta

The new snow machine will be put into operation next month to offset the bad snow conditions of the late autumn in the glacier piste. The snow is being used to make a path between the bottom of its high altitude glacier and the cable car station from where skiers and boarders can get back up the slopes to access the year round ski area. In years gone by the glacier did reach this lift station anyway, but over the past two decades it has melted away and in late autumn, around the beginning of October, the glacier piste ends 500m before the lift station.

The energy it requires for a year is the equivalent to that of one household.

The new snow machine, which is produced in Israel, had a delivery period of one year and costs around CHF 2 million (EUR 1.19 million).

IDE’s All Weather Snowmaker for Zermatt

The financial viability of the ski resorts depends to a great extent on favourable snow conditions and the snow-reliability of its ski areas. Nowadays ski operators adopt technological measures to reduce the risks from a snow deficient winter.

Snowmaking is the most widespread strategy to extend the operating season and to secure and guarantee the revenues of the ski resorts. Zermatt Bergbahnen is the first ski resort to order a new kind of artificial snow system: the IDE’s All Weather Snowmaker.

It will be put into operation at the end of September 2008 to offset the bad snow conditions of the late autumn in the glacier piste. As Daniel Loggen, Director of Zermatt Tourism, says “We want to offer our guests perfect skiing enjoyment – so the innovation has come at just the right time”.
