Abstract: The European Directive 2010/31 claims that by 2020 only (nearly-)Zero-Energy-Buildings may be built. To reach this goal, it is pertinent for buildings to be energetically optimised first. The remaining energy demand must then be covered by on-site renewable energies (PV, geothermal etc.). With the area of use (energy demand) and the size of the building envelope / estate (renewable energy supply) in competition with each other, the maximum number of building storeys will be most likely limited. For 15 different climatic locations worldwide, the energy demand of optimised office rooms was simulated and compared with the possible renewable energy production on site. For every location, a good correlation was found between the simulated energy demand and data like heating and cooling degree hours. Correspondent linear equations are given here. As another result, the maximum number of possible storeys for ZeroEnergy-Buildings was derived as to be between 3 and 10 depending on the location.
