A Methodological Proposal for the Characterization of Building Heritage from the Second Twentieth Century for Renovation Purposes

With the signing of the SECAPs, European cities and municipalities are taking steps to respond to an energy problem deriving from the demand for summer air conditioning, which, since the early 2000s, has exceeded the demand for winter heating. Sustainable urban regeneration requires action by applying an integrated approach between the sectors and professional figures involved, following the principles of sustainable development. Sustainable construction focuses on reducing the environmental impact of the building industry using renewable and recyclable materials, reducing energy consumption and embodied energy of building materials. The recycling and reusing of waste materials can lead to energy savings, cost reductions, potentially improved products, and reduced waste generation-related hazards to the environment. However, an important consideration when using green construction materials as alternative raw materials is having a thorough understanding of their chemical, mineralogical, and physical properties. This knowledge is essential to ensure that recycled materials can be effectively integrated into materials production without negatively impacting the final product quality or production efficiency. We present here processes developing existing materials which are substantial to ensure the maintenance of that heritage recognized, experienced and enjoyed by the people living a given territory.
