Costs and Life-Cycle Energy optimization for a low energy housing renovation actions

RÉSUMÉ / ABSTRACT :

Economic cost is a very important decision criterion in renovation projects. Environmental impacts are also gaining more. Renovation’s actions will improve energy efficiency in building but also concerns manufacturing, transportation, emissions,… In this paper, an approach for optimizing both economic and environmental costs is presented. A procedure of actions optimization based on thermal dynamic simulation has been successfully applied for a house in France. Different scenarios are studied and analyzed.
