The traditional architecture is founded as a defining element of the
identity of a region, and its essence should be preserved and conserved by
means of maintenance and recovery actions. Thus, the best solutions and
proposals for intervention should be looked for but this doesn’t imply a back
to back innovation and at construction progress. This work includes the
description of techniques for maintenance and conservation of bioclimatic
solutions found and inventoried in the north of the Iberian Peninsula, with
special focus on a unique bioclimatic solution known as Transition Spaces
(from the interior to the exterior of the buildings and vice-versa), whose
main purpose is to ensure protection from the elements when entering or
exiting buildings, to contribute to the improvement of the buildings thermal
performance and to create sheltered interior/exterior living spaces. This
architectural characteristic is based on the building’s solar exposure,
predominant winds and geographical and topographic conditions. It is
important to recover the historical heritage in a sustainable manner, allowing
it to become an engine of development for both urban and small rural centres
that exist in the periphery of the bigger cities.
