Bioconstruction: Beyond hempcrete

One of the common beliefs about bio-construction is that it is only for rich people. According to Mike Lawrence, Professor at the BRE CICM (Centre for Innovative Construction Materials), University of Bath, UK, this is a myth: "If you compare like with like, so if you compare a building made out of conventional materials with the same thermal performance as a building made out of biobased materials such as hemp, the latter is cheaper. Under the EU project called Isobio, we did studies in the UK and in Spain. If you compare the British construction systems, the wall of a hemp building is about 30% cheaper per square metre than the one made out of traditional construction materials. In Spain it is even better, the wall is more expensive there, so a hemp system will be about 55% cheaper than a typical Spanish wall with the same thermal performance."   Read more....
