Basics

In the course of the Alpine World Ski Championships held in Schladming in 2013, a congress center was built for up to 1,000 journalists and media people from all over the world. Riepl Riepl Architekten from Linz won the general planning contract and commissioned ALLPLAN for the building services and building physics. ALLPLAN was also invited by the municipality of Schladming to find a cooling concept for the project that would meet both economic and ecological requirements in terms of sustainability.

Technical details

An analysis of the conditions and the possible synergies available showed that "hybrid cooling" is the most sustainable solution. The water from the River Enns is taken via the existing pressure pipe, which is used for artificial snowmaking on the Planai, and used to cool the chiller or, if the temperature falls below 12°C, to cool the building directly. In the case of the media center, around 30 tons of CO2 can be saved annually by using the river water. This corresponds to the CO2 emissions of an average car with a mileage of approx. 170,000 km - 4.25 times the earth's circumference.

In addition to this innovative cooling system, sustainability was also a top priority for the other technical systems. Heat comes from the nearby biomass cogeneration plant, electricity consumption is partly covered by a photovoltaic system on the roof and waterless urinals have been installed to reduce water consumption.

In the architecture, sustainability is expressed in the use of regional building materials - loden fabrics for the interior design and timber for the sun protection.
