As we celebrate World Creativity and Innovation Day, it’s key to reflect on the groundbreaking innovations that are reshaping the landscape of sustainable construction. BIOBUILD, while developing transformative solutions toward energy efficiency buildings, pushes the boundaries of innovation.

BIOBUILD’s main innovative action in the project lies within its production processes and the methods used in wood to regulate heating conditions. The main method is the impregnation of bio-based Phase Change Materials (bioPCMs) into solid wood and fibers, highlighting the commitment to the use of eco-friendly building materials. The chosen method of impregnation enables precise control over parameters such as vacuum depth, pressure, duration and temperature. This not only enhances the effectiveness of bioPCMs but also enhances wood with desired properties like pressure and durability, all while minimizing chemical usage and environmental impact.

In the project, solid wood flooring and wallboards are targeted as bio-based building materials. The wood flooring is designed as a parquet consisting of a softwood-core layer placed between the bottom layer and upper surface layer. The wood fibers are also impregnated with the bioPCMs and bonded into bio composites to produce the wallboards.

 What about the thermoVuoto process? In BIOBUILD, the project employs thermal modification to migitate the leaching of bioPCMs from solid wood and fibers. The aim of thermal modification is to enhance the permeability of wood, improve retention of impregnated bioPCMs, increase dimensional stability by reducing absorption and enhance durability against biodegradation. The technology is designed to provide an eco-friendly and efficient method for enhancing such properties of wood, improving its permeability, increasing the retention of bioPCMs, ensuring a stronger hold following the impregnation.

Additionally, the project uses the microwave (MW) approach to enhance bioPCM retention and prevent leaching. By precisely controlling the drying process and modifying wood structure, the MW approach ensures optimal impregnation, showcasing the innovation driving BIOBUILD’s commitment for sustainable solutions.

What happens next? Once the bioPCMs are impregnated into the solid wood and the parquet layers are glued, the impregnated wood fibers must be bonded to form bio composites. These bio composites are used as wallboards or integrated into other building elements. The impregnated wood fibers will be processed into bio-composites using only bio-binders. BIOBUILD showcases three bio-binders: plant oil resins, lignin and fungal mycelia.

In celebration of World Creativity and Innovation day, let’s embrace and learn from the novel approaches of BIOBUILD as it establishes the standards for a greener, more sustainable future in construction.
