NZEB Characteristics of European Residential Buildings and Assessment of Refurbishment Scenarios Using Building Typologies

The European Directive on the Energy Performance in Buildings (EPBD) mandates nearly-zero energy new buildings by 2020. This presentation reviews characteristics and benchmarks of NZEBs from within existing building stock. A European-developed framework for assessing residential building refurbishment is presented based on regional/national building typologies for large building portfolios. This procedure enables key experts/non-experts to ensure high-quality retrofits, check regulatory compliance, track/steer refurbishment processes and quantify energy savings. The presentation concludes with results of future EU Member State refurbishment strategies to make realistic projections of residential heating energy use and support efforts for meeting energy savings or emissions targets.
