Still following the post above see below an extract taken from a report published a few days ago on the assessment of the progress made by EU countries towards the implementation of the Energy Efficiency Directive:
"The NZEB requirements in the most Member States are less ambitious than the benchmarks recommended by the Commission in both residential and non-residential buildings....With the forthcoming introduction of NZEB requirements for all new buildings as of 2021, the main challenge for the decarbonisation of the building stock by 2050 is to increase the current low renovation rates..."
The report on the State of the Energy Union disclosed on October 14 also mentioned that
"...to at least double the annual energy renovation rate of residential and non-residential buildings"
Also important is the fact that more than 220 million buildings need to be energy renovated. Fortunately, that will help to tackle the current economic crisis because "per euro invested, building renovation is our biggest job creator" with 12-18 local jobs for every million invested.
PS - In this context, it makes sense to advertise the book below which is indexed in the Master Book List of the Web of Science. Part One addresses thermal insulation materials, phase change materials, reflective materials, smart windows, solar collectors and building-integrated photovoltaics. Part Two reviews measurement and verification models, smart energy systems, and optimization with genetic algorithms and neural networks. The book concludes with several interesting case studies on energy-efficient retrofitting for various building types in different climatic zones.
