Straw instead of concrete – resource-efficient buildings
S-House – Building with factor 10
Innovative building concepts should consider the energy demand as well as the lifecycle-wide
resource requirements. Instead building with resource intensive materials, here, straw is used
as building material.

The construction sector is an economic sector with high
energy and resource requirements. Along the construction
lifecycle the phases “raw material production”, “building
material production” and “use phase” have turned out to be
especially resource-intensive. Of central importance to the
construction of new buildings and renovation is the planning
phase, where strategic material selection can steer the
material intensity of all remaining lifecycle phases. While
energy-efficient construction is being already exercised in
practice, aspects of resource protection often still remain
unnoticed.

The Austrian group ’’Angepasste Technologie“ (GrAT) managed
to reduce the lifecycle-wide resource requirements
in comparison to customary buildings by a factor of 10
through the construction of a demonstration S-HOUSE
building. Within the framework of the program line ’’house
of the future“, an integrated concept was developed, which
connects all relevant aspects of sustainable construction.
In addition, the straw bale construction, the elementary
concept for the S-HOUSE, is also economically interesting.
The demonstration building shows the compatibility of traditional
building materials with innovative constructions
to normal passive house costs. During the deconstruction
phase the building materials can be easily separated and,
therefore, reused. The building design of the S-HOUSE and
used components correspond to current needs of users
without consigning disposal problems to future generations
or forcing a subsequent use.
