(noise) and 3.7 (temperature) to 4.6 (air quality) and 4.7 (daylight). The mean value of the assessments of
the 5 parameters and the general assessment of the indoor climate last summer was 4.3. This means that
the occupants were most dissatisfied with the noise and temperature conditions and most satisfied with the
daylight conditions and air quality. Nearly half (48%) of the occupants specified that they experienced noise
from the technical installations, 14% experienced noise from activities inside the building and only 5%
experienced noise from outside the building. From the comments, it appears that the noise comes from
several sources like ventilation system, heat pump and rainwater pump. One-third (36%) of the occupants
specified that they experienced that it was too warm during summer and 11.4% that the temperature varied
too much. As expected, due to the general satisfaction with daylight conditions and air quality, only 20% (9)
wanted more or less light in the living room, where 16% (7) would like less light and only 7% experienced
stuffy air.
and 3.7 (temperature) to 4.5 (air quality) and 4.7 (daylight). The mean value of the assessments of the 5
parameters and the mean value for the general assessment of indoor climate were 4.1. This means that
during winter the occupants were most dissatisfied with noise and temperature conditions and most
satisfied with daylight conditions and air quality. More than half (58%) of the occupants specified that they
experienced noise from the technical installations, 15% experienced noise from activities inside the building
and no one experienced noise from outside the building. Of the respondents, 30% (12) specified that they
experienced that it was too cold, and 18% (7) found that the temperature varied too much. Some
respondents explained that problems with temperature conditions were related to various technical
problems, see below. Moreover, 20% (8) of the respondents indicated that they experienced problems with
draught. The occupants generally expressed satisfaction with the daylight conditions and air quality, where
only 5% (2) of respondents indicated that they experienced problems with too little daylight. Less than 20%
(8) expressed that they would prefer to have more or less light in some rooms. No one experienced stuffy air
and unpleasant smells.
energy is a threat to good indoor climate and that living in a low-energy house is synonymous with living in a
house with a poor indoor climate. Therefore, to put the problems in perspective, a comparison with the
occupants' previous house was made by asking "How do you experience the air quality in your new home
compared with your former home?" and similar for temperature conditions and noise. A majority (77%) of
the occupants responded positively that the air quality was "better" in their new house. For the temperature
conditions, nearly half (48%) of the occupants found it "better" and 25% found it to be "worse". One-third
(34%) found that the noise level was "better" now, whereas 39% found that it was "worse".
noise level from the technical installations. Since the noise level was not measured, it is not possible to
evaluate whether requirements (Danish Building Regulations 2010) are met. However, the occupants'
response show that it is relevant to perform control measurements and it is recommended to evaluate
whether the existing requirements are sufficient. Secondly, more comfortable conditions of temperature
should be provided, i.e. less warm conditions in summer, warmer conditions in winter, and a more stable
