Energy Performance of Buildings 2021

Dear Colleagues,

The long-term renovation strategy supports the change of the national building stock into a highly efficient and decarbonized building stock by 2050 and at a cost-effective transformation of existing buildings into nearly zero-energy buildings. About 70% of the building stock of 2050 already exists today, which means that most of the energy reductions will have to be achieved by deep energy renovation of existing buildings. To increase the renovation rate, we need industrialization and modular renovation. The difference between the predicted and real energy performance can be significant. To overcome these problems, more information, results, and successful case studies targeted to nZEBs renovation are needed.

This Special Issue aims at stimulating the exchange of ideas and knowledge on the deep energy renovation of buildings. To this purpose, original contributions containing theoretical and experimental research, case studies or a comprehensive state-of-the-art discussion are welcome for possible publication. Relevant topics for this Special Issue include but are not limited to the following:

• Deep energy renovation;
• nZEB renovation;
• Minimizing heat loss of the building envelope;
• Performance and energy efficiency of service systems;
• Prefabricated renovation solutions;
• Minimizing the energy performance gap;
• Cost-optimal measures for renovation.
