The aim of this paper is to present one solution to integrate more accurate environmental
assessment methods in rating systems and that could be used to support the design
teams’ decisions that aim the implementation of low impact building solutions. The solution is
the development of a LCA database that is based in the EPD’s (Environmental Product Declarations)
approach and that gathers the quantification of several environmental impact categories
of the most common building solutions used in Portugal. This database is in continuous update
and now covers about 50 building solutions for floors and exterior walls, 40 building materials
and the impacts related to the use of 12 systems for acclimatization and hot water
