 It is surprising that the results of the average measured values agree so well with the PHPP calculation. This is probably coincidental, because neither the accuracy of the measurement nor of the calculation is very high. Nevertheless, the depicted values are actual measured data - and the calculated results are those which were computed before the start of construction and already published before completion of the buildings. \\

+We often get the question, why there is such a huge [[operation:operation_and_experience:measurement_results:energy_use_measurement_results#summary|fluctuation of the energy demand between different users]]: This is actually the case for all energy standards and not specific for energy efficient buildings - and it does not matter much in the case of passive houses, because even the highest consumption is still very small.\\
