The Portuguese housing sector experienced a significant growth throughout the 20th\ century, particularly in the last quarter, after the democratic revolution in 1974. In fact, the\ number of buildings built between 1970 and 1990 is more than one third of the buildings actually\ existing in Portugal. Therefore most of them were built before the publication of the first\ regulation concerning the energy efficiency in buildings. Regarding this scenario, it would be\ expected that rehabilitation activities would represent most of the current construction\ activities. However, given some remaining barriers from old social policies, this situation is not observed; actually building retrofitting is the least significant sector, accentuating the\ degradation level of major part of the Portuguese housing stock. Several studies show that the main problems are found in the building{\textquoteright}s envelope elements, such as roofs and fa{\c c}ades. Based\ on this context, the aim of this paper is to introduce some examples of building retrofitting\ systems that, adapted to the Portuguese main needs and requirements may represent\ sustainable solutions to overcome the identified needs of Portuguese buildings{\textquoteright} envelope.
