Application of hourly dynamic method for nZEB buildings in Italian context: analysis and comparisons in national calculation procedure framework

The Energy Performance of Buildings Directive (EPBD 2018/844/EU) requires to Member States to upgrade the methodology for the energy performance assessment of buildings. The current calculation method, based on the monthly quasi steady state calculation procedure, could be replaced in the next years...
