Old buildings in need of refurbishment and how it contributes to urban sustainability.

Old buildings often require rehabilitation for various reasons, and this process can contribute significantly to urban sustainability. Here are some of the main reasons and how they impact sustainability:

1. Structural and functional obsolescence:
   • Over time, buildings can become obsolete in terms of their structure and function. Rehabilitation may be necessary to upgrade infrastructure, electrical and plumbing systems, bringing them up to current standards and making them more efficient.
2. Energy efficiency:
   • Many older buildings do not meet modern energy efficiency standards. Retrofitting can include insulation improvements, installing energy efficient windows, and upgrading heating and cooling systems, contributing to sustainability by reducing energy consumption.
3. Compliance with building codes and regulations:
   • Old buildings often do not comply with current building codes and regulations. Rehabilitation may be necessary to meet legal and safety requirements, ensuring that the building is in compliance with current regulations.
4. Preservation of cultural heritage:
   • Many old buildings have historical and cultural value. Rehabilitation not only preserves this architectural heritage, but also prevents demolition and the irreparable loss of a community's cultural identity.
5. Adaptation to new needs and technologies:
   • The functions and needs of buildings change over time. The rehabilitation can adapt buildings The new buildings are designed to meet new uses, incorporate modern technologies and respond to the current demands of the occupants.
6. Improving the quality of urban life:
   • The building renovation The use of antiquities can contribute to the improvement of the quality of life in urban areas by revitalising neighbourhoods, providing housing and attractive, and to promote economic activity in the area.
7. Reduction of pressure on urban land:
   • Al renovate buildings existing rather than building new, the pressure on urban land is reduced. This avoids uncontrolled urban sprawl and loss of green space, contributing to sustainability by making efficient use of existing urban resources.
8. Promoting sustainable densification:
   • Rehabilitation can contribute to sustainable densification by renovating and improving the efficiency of existing buildings, allowing higher occupancy without the need to expand the built-up area.
