This papers presents the application of the Methodology developed in the IEA Annex 56 to a case study located in Tudela, northern Spain. The life cycle cost and impact assessment of three renovation scenarios (including different types of heating systems in two of them) and a reference case have been evaluated. Results show that all renovation scenarios studied are cost-effective achieving at least a heating demand reduction of 40%. The actually executed renovation, if additional on-site renewables are installed, constitutes the most cost-effective scenario; however a deeper renovation has lower final energy use and carbon emissions associated
