Environmental LCA database for conventional portuguese building technologies

Abstract

Nowadays there is an increasing concern with the high emissions of polluting gases, the high use of natural resources and energy related to construction sector. There are several environmental impacts in this sector that can be moderated. This paper presents a study that allows the designers to quickly and easily apply the Life-Cycle Assessment (LCA) method to projects and therefore to understand which solutions are the best in what regards to sustainable construction. To fulfill the abovementioned goals this work studies the environmental per-formance of building technologies covered by the ITE50 manual coefficients of heat transfer of the building envelope elements . This manual covers the majority of building technologies used in Portugal.
