In a new report, Navigant Research have analyzed the European market for residential and commercial building energy efficient products and services, and forecast that it will almost double in size over the next decade, from €41.4 billion ($56 billion) in 2014 to €80.8 billion ($109 billion) in 2023.
The market for energy efficient buildings in Europe is supported by stringent regulations that apply across the European Union. As a result of legislation, including the Energy Performance of Buildings Directive and Energy Efficiency Directive, mandatory changes to country-level building codes are increasing the performance requirements that apply to new construction and major renovations of existing buildings. These codes are pushing toward the delivery of nearly zero energy buildings by 2019 and 2021 for public and private buildings, respectively.
