Climate change, driven by greenhouse gas emissions, is a growing global concern, threatening world-wide environment, health and economy. Energy needs for buildings are large source of emissions. As the energy strongly depends on weather patterns, this paper investigates how climate change may impact building heating cooling loads, cost-optimal efficiency measures, renewable production. Eight locations (Stockholm, Milan, Vienna, Madrid, Paris, Munich, Lisbon, Rome) highlight differences among European climates. Weather datasets, commonly used in simulations, evaluated to see climatic parameters have changed over recent decades. A future scenario (with uncertainties) analyzed year 2060. files drive simulations standard baseline (Nearly Zero Building) NZEB residential whose design improved using cost-optimization approach. The analysis indicates most currently available datasets cannot assure reliable results with simulations. We find balance will significantly under conditions: decrease 38%–57%, while increase +99%–380% depending location. In NZEBs, measures reduce overheating be favored (e.g. roof insulation, window type, solar shading, envelope finishes), illustrating improving more crucial within scenarios. Compared baseline, efficient NZEBs enable much better cover needs. There also advantages from reducing winter summer peak demand, particularly when coupled short-term electrical storage. When resource limited winter, airtight, better-insulated improve PV self-consumption.

This paper offers an overview recent policy developments and examines introduced provisions on new existing buildings. While nearly zero energy buildings (NZEBs) remains current standard since 2011 for buildings, emission (ZEBs) are set as future target 2030. Accordingly, this provides insights into ZEBs, clarifying when concept brought out. In particular, it discusses methodological aspects that ZEBs should address, outlining decisive efficiency renewable energy. main features pragmatic ZEB definition which be distinguished from other concepts.
