The University of Bath is undergoing a project to find environmentally friendly building materials that can be used as an alternative to the current products used within the construction industry.
A straw house came up as a viable option. Straw is not only a renewable resource, but also a farming by-product, which made it a popular choice for the researchers. It can be locally grown and absorbs carbon monoxide, therefore buildings made from straw have zero or even a negative carbon footprint. It can potentially provide such good insulation that normal heating may not be necessary, keeping running costs low and minimising environmental impact.
The construction itself has been built using prefabricated panels, consisting of wooden frames filled with straw or hemp, then rendered with a breathable lime based system.
Research into alternative building materials is important as cement contributes up to 10% of all carbon dioxide emissions. Hopefully this project, which over the year is to be monitored, will prove that straw is a sustainable building material. Let’s just hope it can withstand all the wolves huffing and puffing and trying to blow the house down!
