The importance of implementing sustainable practices in buildings is duly proved
and understood by the majority of the population. However, its implementation is not yet a
reality. Some studies have been performed with the goal of understand this lack of use of
sustainable solutions, among building sector stakeholders. The conclusion is that one of the
main factors contributing to this is related with economic constraints. Several studies have
proven that many sustainable practices correspond to minor costs than traditional practices in
a life cycle perspective. However, the building sector stakeholders are not aware of this and do
not implement sustainable practices commonly. In this paper a cost‐benefit methodology willing
to cross this barrier and promote the sustainable practices implementation is presented.
