| The building sector is well known to be one of the key energy consumers worldwide. The renovation of existing buildings provides excellent opportunities for reducing energy consumption and greenhouse gas emissions. In this paper a multi-criteria methodology is proposed for the comparative analysis of retrofitting solutions. Life Cycle Assessment (LCA) and Life Cycle Cost (LCC) are combined by expressing environmental impacts in monetary values. A Pareto optimization is used to select the preferred strategies. The methodology is exemplified by a case study: the renovation of a representative housing block from the 60s located in Madrid. Seven scenarios have been proposed for the analysis of the energy saving measures (ESM). Results show how current renovation strategies that are being applied in Madrid are far from being optimal solutions. The necessary extra investment for the optimal improvement of the envelope compared with the common practice to date is not so high (8%) considering the extra life cycle environmental and financial savings (45% and 87% respectively). | |
