 Of the household appliances in the list below, one appliance was assumed for each dwelling unit. The best appliances available on the market in terms of energy efficiency were chosen based on [Spargeräte 2014] and [Ecotopten 2014]. In the cases indicated with a *, the stated consumption was multiplied by 1.5 in order to compensate for standby losses and potential optimisation of the appliances to the test cycle (testing in the eco-programme,​ normal operation with the automatic programme, etc.). Of the household appliances in the list below, one appliance was assumed for each dwelling unit.

 Auxiliary electricity consumptions depend strongly on the systems used. For the standard case, underfloor heating (optimised for electrical supply with an efficient heat pump, may also allow simple daytime storage of renewable energy) in combination with an optimised hot water circulating system (hot water storage tank for reducing the load on the grid, 60 °C) is assumed. This results in the following sources of released heat from auxiliary electricity uses: Auxiliary electricity consumptions depend strongly on the systems used.
