Realized Goals: Pollution Control

1. Low Energy House by special Wood-Construction
   The entire raw construction had been prebuild at the factory and transported by special trucks to the Eibelsfleckalm. From there the wall elements reached the building area by a few helicopter flights. The material for warmth insulation had been brought by members of the section via ropeway to the building area. The value of the warmth insulation is double the norms of the respaective laws because of the compact construction and minimum outdoor wall space.
   
   
2. No Wood Protection Means
   The entire wooden construction and outdoor and indoor wooden layers (35 mm massive mountain larch with a special sawing) are not dealt with and are free of wood protection means. Exceptions are only such elements which had been delivered by the factories already sealed, f.i. windows, doors, parquet floor, separation walls at the public hygiene.
   
   
3. Electrical and Thermal Energy Supply by Block-Heating-Generator (BHKW)
   The gas-driven BHKW delivers 240 Volt one-phase and 400 Volt three-phase current for the necessary systems, f.i. ropeway, water pumps, cooling elements, drinking water germination, illumination (regular energy saving lamps, and move-sensors), smoke warners, radionet converter, steering of the warmth stores, and for the illumination of the nearby hut of the mountain rescue team. The operation concept avoids "energy eaters", done with carefully balance.
   This concept shows its principle:
   
   
4. • If the work is easier done when being environmental friendly at annother location (f.i. laundry washing, drying and ironing, will be done down at the valley. There is only a small amount of laundry because of the force to use an private own light sleeping bag in the bedrooms); or
     
   • 
     
   • if devices can be avoided by changing working courses f.i. microwave, coffee machine, water heater, cold storage box; or
     
     
   • if regular available devices can be used alternatively, f.i. gas driven refridgerator, dish washer hotwater provided, gas driven continous-flow water heater; or
     
   • 
     
   • if other parts of the installation can fulfill the function, f.i. steam outlet or heating stove.
     
     
   • that the block heating generator operates with highest efficiency and optimum gas consumption on full power a soffisticated allotment controls the priority of parallel working consumers. A 48 Volt battery system stores sufficient energy via a three phase inverse rectifier to overcome a five day emergency operation.
     
     
5. Warmth Recovery of the Block Heating Generator
   The entire warmth earned by cooling the generator (this is 2/3 of the energy consumed!) will be stored in a warmth store tank with 8000 liter (special production of the company Förster in Bichl). Warmth exchanger inside the tank deliver hot water for the kitchen and the hut heating (under floor heating at the ground floor and radiator heating at the upper floor).
   In case of heating problems or as additional heating a tiled stove in the dayroom is used. The BHKW needs no smoke outlet but only a non rusting waste gas pipe with condensate pump.
   
   
6. Reduction of Emissions by suited Engineering
   The gas driven BHKW is sound insulated (>50 dB) and is operated with faint sound in the cellar.
   It is sufficient to fill the liquid-gas tank at the base station of the ropeway one times per season by a tank car.
   By lenghtening the durability of food and fresh-food in special cooling cells supply transports on the 11km long forrest road are reduced.
   The - up to then - weekly transport of drinks in cooled bottles is now reduced to a one times a month transport of barrels. This is possible because the supply pipes from the barrels in the cooling cell up to the six taps at the bar are all the way cooled.
   Nice looking heatable rooms with private hygiene for the personnel offers the possibility of a steady stay of personnel and avoids daily transports to the hut.
   A copper layer at the roof and also the copper gutters avoids regular painting with glimmer color. The rainwater collected by the roof then must be kept away from the biological purification plant.
   
   
7. Reduced Endangering of Transports
   The change of the energy supply from fuel to liquid gas operation avoids fuel to be transported to the hut because it is no longer necessary.
   
   The liquid gas runs from the tank beside the base station of the ropeway through a 600m long gas pipe to the 230 m higher situated hut.
   
   This measure was invented by members of the section. The pipe was finished under supervision of some engineers of the section, because there are not yet handicraft companies available for such work. A well qualified special company checked the installation technically and gave ok.
   
   
8. Health-improving Measures
   All faucets of the hut offer drinking water quality.
   
   Inside the entire hut smoking and open fire is strictly forbidden.
   
   All windows have special locks for safe fresh air ventilation when there are rain or thunderstorms.
   
   Emergency illumination, smoke warners, additional devices and a complete plastic-free cable-net of the electric energy supply increase safety for visitors and personnel in case of fire.
   
   All fitments are new. A reuse of old fitments was avoided. Only some woollen blankets had been chemically cleaned.
   
   Any stuff which could emit solvent had not been used.
   
   The floors in the mattress rests and bedrooms (Pavatex) had been dealt with biological wax.
   
   
9. Ease of work with the cleaning of the hut
   The daily sum of work with cleaning the hut had been minimized.
   
   The complete ground floor has a ceramic layer, an under floor heating and floor outlets in the drying room, kitchen and public hygiene.
   
   Regularly one daily cleaning with clear water is sufficient; in case of heavy mud with additional liquid soap.
   
   All furniture in the dayrooms is aimed to highest possible free space on the bottom.
   
   The upper floor with the mattress rests, bedrooms and public hygiene may only be entered wearing light slippers or sandals.
   
   All floors can be easily hoovered or wet cleaned.
   
   
10. Comfort for Visitors
    The ceilings in the dayrooms are white and the floors are light. So the day over brightnesss is there without needing artificial illuminiation.
    
    To dry wet outfit a spacy drying room is available with unloosable hangers on three movable racks. In the shoe-shelf water flows easily away.
    
    All sleeping opportunities offer a space of 2m x .9m. Some bedrooms offer a length of 2.10m. In the bedrooms there are maximum 4 beds and a comfortable freedom for moving. Great importance was laid on sufficient breathing air per person.
    
    In the public hygiene of the ground and upper floor warm water is available (upper floor: shower). The ladies lavatory has addititonally 2 separate single cabins available with wash basins .
    
    
11. Summary
    Together with the biological purification plant and the deep wells for the drinking water supply from former years with the new hut an overall-network has been come into being at an island situation. It has fully reached the latest state of the art and fulfills the actual state of a preventive pollution control. All devices are robust and easy to maintain ( A hut-keeper is not a service man)
    The hut represents again a special goal for hikers and tourists who would like to avoid the milling crowd at the cable ways of Brauneck and Herzogstand. Already in the past the tourists information offices of the cities around had given the hint to this "Oasis of qietness".
    
    The members of the German Alpine Sektion Tutzing have shouldered 67 percent of the entire costs (2.5 millions DM) for this project in the public interest. Additionally they achieved a huge number of working hours without reward.
