Project summary
The Schiestelhaus is the central alpine base at the summit plateau of the Hochschwab mountains. It is in possession of the mountain club ÖTK, on 2.153 m sea-height and lies directly underneath the main mountain crest. The existing house was 120 years old. It had 110 sleep places and represents a key building for the alpine development and security in the Hochschwab chain. The new hut is a pilot project for solar and ecological building and can be seen as test on extreme conditions for normal plants. The modular concept of the system is the most important innovation of this project. Conventional PV plants have a weak point at the interface to battery. The interconnection of different energy systems (e.g. PV, biomass, wind) cause difficulties, since a synchronization of the plants on a consumer net was not posible.

Best practice project
The energy saving passive house quality connected with a hybrid system of photovoltaic, thermal collectors, heat recovery and a back up system with a plant oil generator care for comfort and a high effective energy supply for all electric and thermal consumers in the refuge.

Remarks and recommended readingOne important factor in planning the whole domestic technology was power consumption: Given average solar irradiation, more than 60% of the annual electrical energy requirement can be covered by the 7,5 kWp photovoltaic system. The installation was mounted in front of the parapet of the terrace because the major part of the facade is being used for the solar thermal collectors. Only a small part of the facade was also equipped with photovoltaic panels. (Source: http://www.nachhaltigwirtschaften.at/(en)/publikationen/forschungsforum/052/teil2.html)
