Despite the great progress made in the energy performance of buildings in recent decades, buildings remain significant energy consumers. Many advanced technologies for increase of energy efficiency have been developed, and strong commitments to increasing the energy performance of buildings have been adopted. The most well-known is the Recast of Energy Performance of Buildings Directive (EPBD), which requires that planners design buildings as nearly zero energy buildings (nZEB), highly energy efficient buildings in which a large share of energy demand is covered by renewable energy sources. In the present article, the evaluation methods and energy performance of advance facade building structures are presented. The structure consists of six-pane multi-layer glass with optional photovoltaic cells integrated in the outer glass layer (BIPV). The method for the determination of the dynamic thermal response model is presented, and the model is validated with experiments. Three indicators were developed (average daily heat flux q̇2 4 at inner surface of the facade structure, the autonomy factor AUT, the and utility factor UTI) to evaluate the all-year energy performance of such advanced building structures according to the heating and cooling energy needs and electricity production. Examples are shown for facade building structures located in three climate regions.
