“…In other words, this European Directive on energy efficiency of buildings (EPBD) requires member states to ensure that on 1st January 2021, all new buildings have an energy "almost zero" consumption in order to obtain the nZEB label [12,13]. The aim of this directive is to enhance interdisciplinary research on building applications sharing knowledge about products, systems, conceptual methods and innovative techniques that combine low energy consumption, renewable energy and industrialization [14][15][16][17][18][19][20][21]. Hence, as we understand, the first step, to achieve nZEB levels of energy consumption consists in designing buildings with high thermal storage and load shifting potential.…”
