Birthday for reconditioning with sun and rain

kohaus existing building a successful modernization with sun and rain - kohaus existing building, the presenting example of a lasting reorganization, celebrates birthday: Long the project demonstrates three years impressively the high comfort gain and enormous resources saving with warmth, drinking water and river. Reorganize with the elements of nature such as sun, rain and earth became success history. Substantially to it the engaged handicraft as well as the industry contributed to convert around such an innovative farmer innovation.

More than worthwhile this way of the ecological modernization was underlines the owner Leo Liebminger. Because the facts are captivating: Minus 87 per cent less gas consumption and a reduction of drinking water consumption around 67 per cent. Besides could be considerably saved through the employment by energy-efficient electrical appliances and energy energy-savings lamp also with the river.

As everything began

At the beginning was a two-family house, which was built in the economic departure years of the 60's. Simply only with four house corners and over it a saddle roof with a roof area to the south. Large windows to the south mark the house still. But otherwise a house like every different one.

The question of the reorganization arose sometime, because at the roof it gave leaky places , tells the roofer master to walter ffel. And I actually dreamed to tap always the free solar power at the roof supplement the owner. And from the dream the roofer and Spenglerbetrieb walter ffel with the family Liebminger developed the plan a large solar plant in the course of the roof reorganization to build. This should supply the house with warm water and partially also with heating energy from the solar heat.

Obviously - simply solar!

In the year 1998, at the beginning of of May, took place the starting signal for the renewal of the building roof and the building of a vacuum collector plant. The decision fell on the vacuum collector for reasons the higher solarslow-acting in the winter for the heating employment. In addition, the optics of the necessary Aufstnderung for the optimization of the solar radiation was more beautiful with the vacuum collector.

For the storage of the renewable solar power a 500 litre of solar storage water heaters was already available in the cellar. Besides still two 1000 litres of buffer memories were installed for heat storage for space heating.

In the summer 1998 the solar plant successfully took up its enterprise and provides now day after day for warm water and to a large extent also for the necessary heating energy. Also the two dishwashers are supplied directly with solar warm water, which saves valuable and expensive river. Since summer also a special washing machine washes 2003 with a warm water and a chilled water connection in the house. Over the warm water connection solar warm water arrives and over the chilled water connection comes to rain water into the washing machine.

If the sun is not sufficient times, then with wood or with a gas calorific value boiler one reheats.

Superlow-energy building

The thermal insulation of the highest floor was the first step to the superlow-energy building , describes Leo Liebminger. After the roof reorganization the thermal insulation of the highest floor from highly compressed Steinwolle and an accessible as well as flame resistant lining took place.
By the higher living quality, comfort and saving of the thermal insulation convinced, the next thought of the Bauherrns already came: Pack up the house all around with thermal insulation and exchange the windows. However not only the Wrmedmmfhigkeit of the building materials should play a role, but also the other characteristics from the building design aspect such as steam permeability, noise control, fire protection etc.

2003 were it so far: The basement walls dammed one with 13 cm thick foam glass plates the one genuine ecological alternative to the conventional extruded polystyrene are. Schaumglas is like the name already says a Glassand blown up with carbon dioxide. With the external walls an water vapor diffusion-open three-layer heat damming plate made of Steinwolle found reciprocally covered with magnesite-bound wood wool light-weight precast plates application. This Wrmedmmplatte has a strength of 12,5 cm.

For the owner not only the thermal insulation was crucial, but also the ecology of the building materials , underlines engineer Klaus Strimitzer, technical technical adviser of the Heraklith AG, if it knocks on the front.

During the facade repair also the windows were exchanged for new high-thermal insulated wood aluminum windows. One put large care also here to the professional connection of the thermal insulation to the windows, like Gottfried Amreich, technical field representative of building with, in detail describes. In addition, with the auskragenden high-grade steel cantilever roof slabs we put, supplement large value on a cold bridge-free attachment the fitter master Franz Schweiger of the stealing and building of aluminum Franz Schweiger.

Rain brings benedictions

The water rushes by the WC-flushing and the owner avowedly with calm consciences valuable and expensive drinking water here is not to no more wasted! Klosplung, washing machines, garden irrigation and cleaning taps are served with highly transparent, smell-neutral and pure rain water. The rain water is collected over roof areas and stored in an underground concrete cistern. From there a rain water manager sucks in the rain water if necessary a consumer and feeds it into the industrial water line.

kohaus existing building successfully uses a rain water use of GEP environmental technology GmbH for the WC-flushings, washing machines, house cleaning and the garden irrigation for more than three years. The rain water quality corresponds to the German drinking water regulation (TVO) for drinking water from own and single investments up to a withdrawal of 1000 m after a laboratory test of the hygiene parameters per year.

kohaus existing building demonstrates impressively the high quality to ours
Rain water use plants, in particular the outstanding water quality " so Klaus Zotter, managing director of GEP Austria.

Much light with little river

The newest innovation within the range of the energy-efficient lighting are the Facility Energiesparlampen. They have an unlimited adjustableness and a Quickstart during the entire lifetime (15,000 h). This makes a rapid light-current approach possible as with a bulb. Thus this Facility Energiesparlampen has an ideal suitability for lighting systems of STEINEL with sensory control and/or automatic shut-off. Or simply everywhere in households, where the light is often turned on and only briefly, as well as a fast source of light is expected.

In the two-family house kohaus existing building OSRAM Facility and OSRAM Dulux EL-Longlife-Energiesparlampen as well as STEINEL Sensorlampen are used. This project is accompanied by a current bookkeeping around saving and effectiveness in practice to document.

All celebrate also

kohaus - existing building means a building with the elements of nature: Sun, water and earth. They mean the life and actually also ecological building. Get simply the cycles of nature with gentle technology in the house. kohaus - existing building arranges from it a collective concept of the superlow-energy building up to the solar and rain water use. Further energy-saving electrical appliances and energy energy-savings lamp are used.
