Cost-effective and sustainable construction is a hot topic due to the extremely tight housing market and the need to make future construction environmentally friendly. Tiny houses made of paper offer a sustainable and innovative alternative to conventional building materials. Paper as a building material is lightweight, recyclable and has a significantly lower environmental impact, as it comes from renewable resources and can be easily recycled at the end of its life cycle. These properties make it particularly attractive for the construction of tiny houses, which already aim for minimalist and environmentally friendly lifestyles. A life cycle assessment (LCA) is therefore essential to fully evaluate the environmental benefits of paper tiny houses. With an LCA, the carbon footprint as well as other environmental factors such as energy consumption, water consumption and waste generation can be quantified over the entire life cycle – from material extraction to disposal. This allows well-founded decisions to be made that contribute to the further optimization and acceptance of this sustainable construction method.
