Straw Bale: An Innovative Sustainable Material in Construction
It is around 10 years that the straw buildings have reappeared on the Europe construction market. Often self-built, these buildings sometimes made only with straw bales and soil aroused interest for their energy and sustainability performance. As there is no feedback existing on this kind of “alternative” construction, it is necessary to verify if straw bale buildings performances can meet today's energy requirements. The purpose of this study is to analyze different aspects of the thermal and energy performance of these buildings using the example of ECO46, an administrative load bearing straw bale building in Lausanne (Switzerland). The conductivity and heat capacity of the straw material were investigated through literature review to find a range of possibilities. Subsequently a dynamic thermal model was created, using the extracted thermal properties, by means of Pleiades+Comfie software. The model was calibrated against two sets of measurements in summer and winter. The results permit to compare the consumption of this building with some standard administrative Swiss buildings. Finally, life cycle assessment (LCA) of ECO46 using SimaPro software was carried out to show the evolution of energy consumption from a building constructed in 1975 to the current construction and to evaluate the main environmental impacts of straw bale building. The result shows that straw bale buildings could be a sustainable solution in the future of construction for its low embodied energy level and its excellent thermal performance if it is well built.
