New assessment method for buildings and districts towards "Net Zero Energy Buildings" compatible with the energy scenario 2015

We present three extensions to current energy building and district assessment methods, which in contrast to previous evaluation methods, not only takes into account building specific energy paramenters and balances, but also links them to the physical energy potential of the project site as well as the future national energy supply scenario. This facilitates the assessment of whether the building or the district is compatible with the energy scenario 2050 without later adaptations or refurbishments. This is necessary because according to current prognoses the current legal requirements in Austria are insufficient for meeting the Paris climate targets, even despite their slowly increasing thresholds.
