No distinguishing between written/oral information was made for this question

The % dissatisfied is determined as the % of occupants answering 1 or 2 on a 5-point scale ranging from Unsatisfactory (1) to Satisfactory (5)

for the question "If "yes" - what is your opinion about the information?

User behaviour

User behaviour is important for both energy consumption and indoor climate. In the present study,
occupants were asked about behaviour in relation to regulation of their indoor climate and practice of
opening windows.

Regulation of the indoor climate summer and winter

To the broad question "Are there typical situations or moments when you are not satisfied with the
automatic regulation of the indoor climate in your home?", 36% of the occupants answered yes. They
specified that they were dissatisfied due to a high temperature during the summer. On another broad
question "Are there typical situations or moments when you are not satisfied with your personal regulation
options?", 43% of respondents answered yes. Most occupants specified that they could not maintain a
comfortable temperature (it was too warm) in the summer, and some were not satisfied with the slow
temperature regulation, and that it was difficult/complicated to regulate the temperature and that they
would like to have solar shading. The dissatisfaction was in some cases related to a floor heating system that
reacted relatively slowly.

Occupants were asked two questions (Q1 and Q2) for a more detailed assessment of their experience of the
regulation of the room temperature, ventilation and solar shading over the year, see Table 19.

For Q1, there was a big variation in occupant's perceived ability to regulate and adjust the three parameters,
since there were answers at all 5 levels on the 5-point scale. Generally, the assessments were on the positive
