On the Refurbishment of the Public Building Stock Toward the Nearly Zero-energy Target: Two Italian case studies

The study presents some results of the on-going European Project, RePublic_ZEB, on the refurbishment of the public building stock towards nearly Zero Energy Building (nZEB). The work is focused on the application of the nZEB requirements to two existing public buildings representative of the 1960s in Northern Italy. Many packages of energy efficiency measures that comply with nZEB requirements are identified and evaluated. The aim is to promote energy efficient but also cost-effective solutions for the Italian building stock refurbishment. The results are presented in terms of «package of measures», energy consumption, global costs, actualized pay-back period and CO2 emission.
