Climate change impact on the future performance of Nearly Zero Energy Buildings : a case study base analysis

Considering buildings large share of Europe's final energy consumption and CO2 emissions, the concept of nearly zero-energy building (NZEB) has received considerable attention. However, the changes in the performance of an NZEB due to climate change has not been studied sufficiently. This paper investigates the effects of climate change on the energy performance of NZEBs in different climatic zones in Italy, for the mid-term (2050s) and the long-term (2080s) periods. The results indicate that climate change affects the energy balance of the NZEBs, while the extent varies among different climatic regions and time periods.
