Abstract

The aim of the present work is to provide the Economic Life Cycle Assessment (LCA) of industrial thermal insulating rendering mortars currently on the market. This assessment is extremely important because it evidences the need for greater control and better assessment of the costs of sustainable solutions in construction, in particular the cost of energy renovation of building envelopes.
Through LCA methodology, it is possible to ascertain the costs incurred, not only during production of mortar but also along its whole service life, from Cradle to Cradle (C2C), including the stages corresponding to the application in a building, maintenance and end of life. In addition to the economic evaluation, an energy study was carried out as well to highlight the benefits of using these mortars for improvement of the envelope insulation, namely the decrease of the heating and cooling needs and corresponding costs over the lifetime.
To sum up, the use of the economic LCA methodology is advantageous in improving the sustainability of the construction, since it facilitates the task of identifying possible improvements according to the study phases and thus to reduce the life cycle costs.
