For us, the Fresh-Air House, also called a Passive-House,
is one of the best and most important innovations since
houses have existed - but they are very rare!
SOTA-DOMUS Passive House advantages:
Up to 95% less energy consumption for heating or cooling
Permanent exchange of indoor air for fresh air
Ideal humidity for the residents - independent of the weather outside
Absolutely clean, fresh air, without harmful fine dust, pollen or other pollutants!
No mould formation
SOTA-DOMUS Passive-House is a
real healthy Feel-Good Home for the whole Family.
There are only a few passive houses, although they have a huge benefit for the
inhabitants and the environment.
What is the reason?
In order to fulfil the passive house standard, special conditions must be created.
The house insulation must be very good, from 0.15 W/(m²K)
The houses must be absolutely windproof.
The wind tightness is tested by a technique developed for this purpose
- the Blower Door test
Since the house is windproof, a ventilation system must be installed.
These 4 essential prerequisites can only be fulfilled with great effort using
traditional house construction methods.
Today's modern timber frame construction in particular has difficulties in achieving the
necessary windproofness and especially in maintaining it over the life cycle of the house.
It is easy to understand why this construction method has this problem.
Timber-frame houses consist of a large number of individual components, which makes it
difficult to make them windproof, but wood "works", over the course of time the
components shrink and the windproofness is lost.
SOTA-DOMUS construction method ideally
fulfils the passive house requirements.
The SOTA-DOMUS exterior wall panels are absolutely waterproof and
The exterior walls consist of only 2 elements, the panels and the connecting profiles.
Already from an outer wall thickness of 150mm, SOTA-DOMUS exterior wall
panels fulfil the required U-value of 0,15 W/(m²K).
The SOTA-DOMUS panels can be broken through at all necessary points in
order to install the ventilation elements.
Due to the flat honeycomb supporting structure of the panels, no reinforcements such
as window lintels etc. are required for openings.
In contrast to conventional construction systems, a passive house ventilation system
with the SOTA-DOMUS construction method is less expensive than a
conventional heating and cooling system!
SOTA-DOMUS construction technology will help the
fantastic passive house technology to achieve a breakthrough
- for the benefit of the house occupants and the environment.
The energy saving potential measured by the
German Passive House Institute over 20 years.
LOW ENERGY HOUSE ~ 75kWh/(m
Calculation example 120m
~ 950 Litre heating oil
Energy cost / year ~ USD 2.400
12.12.22 Current price Germany / litre heating oil ~ USD 2.5
Emmision / year ~ 2.800 kg
When we see these impressive results, we have to ask why this valuable technique,
which has been known for a long time, has not already been made obligatory in
With its outstanding construction technology, SOTA-DOMUS Construction
technology saves enormous amounts of material and conserves our planet's
This material saving leads to an enormous reduction of CO
in the construction
The diagrams show more than clearly how dramatic the additional CO
through the SOTA-DOMUS passive house standard.
With all the concern about our climate, the reduction of energy consumption by
up to 95% is a decisive factor with permanently rising energy costs.
home shown here as an example saves more than USD 2.000 per year at
current heating oil prices.
Projected over 20 years, the savings amount to more than USD 40.000.
Also very remarkable are the CO
savings of ~ 2.600 kg annually.
Projected over 20 years, the CO
savings result are incredible 52.000 kg.
SOTA-DOMUS construction technology can't get any cheaper
and more environmentally friendly than this!
