In the summer of 2011, the owners visited the Kneißl-Spiegelhauer Architekten Architectural Office from Augsburg, for the passive house design.
The plot are perfect for family passive house construction, southern orientation towards the garden area, no adjoining building in the surroundings. On March 2012  the licensing plans along with the export plans was completed, so the construction could begin.

In addition to the family passive house criterion, the builders wanted to design a “simple” building, as well as an important consideration for future use of the house. To this end, the architect was able to set up a later elevator. For the time being, the lifespan is used as a storage tank.

The thermal insulation of the sheet was made by prefabricated pressure-proof XPS insulation.
By using prefabricated elements it is easy to solve the thermal bridge construction.

The cellar is part of the thermal envelope. The reinforced concrete cellar had an XPS thermal insulation 24 cm thick. 30 cm EPS insulation was used on the outer frame structure of the ground floor and the floors.

The ventilation system pipes (plastic tubes with a diameter of 75 mm) are placed in the basement and above ground floor. Of course, during the static planning, the location of the mechanical wiring was taken into account.

Heating and hot water supply is provided by an aqueous heat pump with earth heat recovery. For preheating or cooling, 2 pcs. 70 m deep drilling was required. Heat dissipation is via a surface heating system. The efficiency of the heat recovery ventilation system is 90%.

U values of passive house structures:
External wall structures: U = 0.106 W / m2K (mean value)
Base floor structure: U = 0.09 W / m2K
Roof structure: U = 0.1 W / m2K
Doors: Uw = 0.65 W / m2K

The line of air closure must be guessed on the designer table. The design plan and detail drawings must clearly indicate the airtight solutions of the small details only to achieve the desired passive house value. Careful design is not enough, and the individual work phases are also to be checked from the point of view of airtightness.

The building’s airtightness value, the result of the Blower Door test: n50 = 0.3 / h.
The qualified passive house family home is a very good example of perfect matching of architecture, energy and building needs.
