Awareness of the importance of environmental sustainability is growing in Italy, pushing more and more people and institutions to invest in eco-sustainable buildings. These buildings offer numerous benefits, including reducing environmental impact through the use of eco-friendly materials and innovative technologies, as well as energy savings and cost reductions through efficient heating, cooling, and lighting systems. However, they also face challenges such as high initial costs and resistance to change. Overcoming these challenges requires innovative solutions such as the use of green materials, renewable energy systems, and bioclimatic design criteria.Once the thermal transmittance calculation is complete, the next step is to create a 3D visualization of the wall. This visualization will allow us to better understand the structure and identify areas that require additional insulation of our school IIS Carafa-Giustiniani.
