In this study, the use of PCM is combined with the ventilated facade constructive system. Its thermal performance is experimentally evaluated and compared against a conventional constructive system during winter season in an experimental set-up located in Puigverd de Lleida (Spain). The PCM inside the air cavity will not only increase the solar absorption capacity during winter but will be used as a cold storage system during warm periods, as well. Significant energy savings of the heating systems have been registered. Moreover, the benefits of using the ventilated facade with PCM might be maximized if its operational mode is well controlled and optimized depending on temperatures, occupancy, schedule of energy demands, solar radiation, and internal loads.
