(class 2015) than "Fremtidens Parcelhuse" (complying with BR10) the indoor climate was perceived as being
better, except with respect to noise from the technical installations.

could expect when they bought their new house. This figure was probably estimated on a standard
calculation not taking into account the actual behaviour of the family, e.g. their use of technical installations,
preferred temperature level or habits of airing out. The expectations of the occupants may therefore not be
realistic and this leads to dissatisfaction, even though the house may be complying with requirements. To
avoid such misunderstandings, occupants should be informed about the assumptions for the predictions and
how their family situation and behaviour may affect energy consumption.
that low-energy buildings are synonymous with poor perceived indoor climate. However, there are
challenges that need to be addressed to make low-energy houses more attractive to ordinary people.
Occupants experienced among other things noise from technical installations and that it was too hot in
summer and too cold in winter, that there were a series of problems with the technical installations, that
their use was difficult, and that the energy consumption was higher than expected.
