Researchers are evaluating the performance of various building materials, including polystyrene integrated cross laminated timber panels, in terms of their structural and thermal properties. Studies are also being conducted on alternative materials, such as vermiculite and agricultural residue based composites, as well as energy-efficient concrete and aerogel insulation. The assessments consider factors such as environmental impact, economic viability, and mechanical properties, with some studies utilizing advanced techniques like machine learning and nano-technology.
