Summary

Project Objectives

The basic idea is to provide and use autarkic energy supply systems for such isolated places of difficult access, high ecological sensibility and greater solar exposure. The present project should show an overall design connecting and optimising all available technical possibilities and providing ecological and sustainable building maintenance.

Sustainable Focus & Contents

The project's goal is to attain almost autarkic building maintenance, meaning that most of the electric energy should be produced by solar panels. In terms of heating and warm water supply, as well as design and insulation the building follows the guidelines of passive houses.

Comfort standard should not be higher than basic, according to the limiting conditions of the special geographic and ecological situation.

The building's use requires flexibility. According to weather and seasons the building's frequentation will not be a constant one. Therefore the building is split up in 2 thermal zones: the basic central supply zone and an additional zone surrounding the central area that will be heated only when needed in order to save energy wherever it is possible.

Expected achievements & exploitations

In general this pilot project could increase the "environmental consciousness" of people enjoying an intact nature and also work as a signal for future building concepts. Though it seems to be a very special building concept for very special locations it could be an outstanding representative for "island buildings" and a demo-project for other buildings with various forms of use.

Location

The prototype of an ecological alpine refuge hut will be applied as a replacement of an old, non-restorable and non-ecologically working building. As a location has been named the "Schiestl-Haus" at the "Hochschwab mountain" in Styria (app.height above sea level: 2100m). In that special case one of the most important aspects will be water protection, because this mountain area is one of the main water sources for the supply of the 2 cities of Vienna and Graz. Therefore it must be well protected against all kinds of pollution.
