Catalonia, and more specifically Barcelona, is recognised internationally for the quality of its public spaces, which are also one of our most highly valued cultural assets. Being able to enjoy high-quality public spaces enhances and intensifies human relations, allowing us to interact with people who do not form part of our own immediate circle, opening up a host of possibilities.
The ageing process of buildings makes it essential to carry out regular maintenance to guarantee they are kept in an optimum state of conservation over the years. Also, as a result of changes in the needs of their regular users or even different uses, more wide-ranging renovations often have to be made. Finally, there is the possibility that the building in question is protected by some form of heritage listing or, even if it is not officially listed, that it has certain formal or decorative features that should be preserved and restored.
The sustainable development of our cities and buildings is becoming one of society’s main requirements along with other needs associated with comfort, durability and economy. Despite the good image that the whole sustainable development movement has acquired, there is still a long way to go. The implementation of sustainable development in the construction sector—which represents around 40% of energy consumption in Spain—is one of the biggest challenges facing Architecture in the 21st century.
