A comprehensive life cycle impact assessment insert ignore into journalissuearticles values(LCIA); is presented, including results for two well-known LCIA methods: CML2001 and Eco-indicator’99, which are compared on their performance through application to the same life cycle inventory for a single-family house in Portugal.   Key Words : Building envelope; environmental impacts; life cycle assessment; single-family house.
