Intervention Criteria

Restoration

The restoration of the Sant Pau Art Nouveau Site is an exemplary process in terms of quality, sustainability and energy efficiency. The enhancement of the heritage, the application of new technologies and the latest advances in energy saving are the main distinguishing features. On the basis of these principles, the intervention process has been divided into three stages:

  • Recovery of the original volumetries: removal of structures and constructions that had been added to the original buildings.
  • Consolidation of structural elements: refurbishing of the pavilions' internal cast iron skeletons, damaged by the passage of time and the effects of corrosion.
  • Design of new facilities and infrastructure: construction of a peripheral ring and a network of underground machine, maintaining the buildings intact and reducing the potential visual impact of the new facilities.

Before commencing the work, the teams of architects undertook a rigorous process of research and historical documentation in order to understand in full the original configuration of the buildings, the construction materials used and the position of the decorative elements.

The restoration has been carried out according to the strictest quality criteria, based on the definition of models of intervention for the restoration of buildings and decorative features, the reconstruction of various architectural elements and the use of specific construction systems, with the ultimate aim of ensuring the consistency and harmony of every one of the actions undertaken.

The restoration of Sant Pau has also been oriented towards the goal of making Domènech i Montaner's architectural complex a truly efficient and sustainable space. The set of environmental technical specifications (PCTA) established in 2010 defined the standards and processes that have been implemented to reduce energy consumption and make the most efficient use of water resources, among other issues.

A good example of this commitment to sustainability is the geothermal system designed for the air conditioning of all of the buildings in the complex. The geothermal facility at Sant Pau, one of the most important in Europe, makes use of the different temperatures of the lower layers of the subsoil to heat or cool a closed water circuit, resulting in savings of up to 60% on the usual consumption of a conventional gas installation. In addition, the buildings are equipped with systems to regulate consumption on the basis of user demand, such as sensors and centralised management and control systems.

The restoration reaffirms the value of the heritage and prepares it for the twenty-first century. Thus, the Art Nouveau pavilions have been equipped with state-of-the-art information technology and communications, installed in such a way as to ensure the conservation of the buildings and their heritage value.
