| Abstract | The luminous environment in a space is one of the key
factors affecting the occupants’ work performance and
mood. An illuminance value is quantitatively standardised
and recommended for a specific space, but
correlated colour temperature (CCT) is not. Although
some studies on CCT conditions have shown that
higher CCT conditions appear brighter to people than
lower CCT conditions, other studies have indicated that
there is no relationship between brightness perception
and CCT conditions. This paper reports the results of
two subjective evaluations of different CCTs on personal
preferences: brightness perception, subjective
impression and work performance; and describes suitable
CCT conditions for a specific space and activities.
One subjective evaluation (field test) was performed
with four different CCT fluorescent lamps in an office
space, and another (photo-image test) was performed
with pictures under four different CCT conditions in an
office, living room and bedroom. The results were
statistically analysed for gender, preferred CCT, suitable
CCT of each space and brightness sensitivity. The
results showed that people preferred different CCT
due to the purpose of a space, and different CCT
conditions for specific activities performed in that
space. The study suggests that changeable CCT lightings
are better than fixed CCT for occupants in a space. |
