Technical, ecological and economical fundamentals of straw bale buildungs - bibliography and analysis of the termal conductivity.

Straw bale construction is a new discovered building technology, which is an alternative to conventional construction technologies. The aim of this work was planning of an ecological, economical, and physical as efficiently as possible straw bale house based on an extensive literature review. For the examination of the building a timber frame construction has been selected. The straw bales in this construction were coated inside with clay plaster and externally with a combination of lime and clay plaster. The roof structure was designed as a green roof and insulated with straw bales. The base plate was also insulated with straw bales.
To check the thermal behavior of the structures described above were thermal bridges calculated using a FEM program. Ecological and economic evaluation of straw bale construction was carried out with reference to the data from the literature.
The performed thermal calculations have demonstrated a very favorable performance of the proposed building components. The achieved low U-values of the components allow the construction of passive houses. The use of self-service in the construction process can reduce construction costs significantly. The use of ecological materials such as: straw, clay and wood allows a low cost recycling of building materials.
Derived from the extensive literature review and on the basis of the performed calculations in this work, we can say that the straw bale construction is an efficient building technology considering it's ecologic, economic and physical aspects. Further hygrothermal calculations including leaks and measurements on a constructed building are necessary to verify the real behavior in practice.
