Methodology for improving and testing the quality of renovation actions: a case study application

The contribution presents a synthesis of some results obtained from an on-going national research program carried out at the University of Bologna, Department of Architecture, focusing on sustainable renovation processes and effective solutions for increasing the energy efficiency of the existing housing stock. The proposed methodological approach is based on a step by step retrofit strategy, tested by a simulation model, aiming to reduce the energy demand from the current significant present value to at least 15 kWh/m2y. This performance level was assumed as the target of the retrofit action that has been developed by assessing the effectiveness of the different technological solutions adopted. This methodology and simulation set are going to be used for a further development of the retrofitting solution that foresees the use of pre-fab wood panels.
