udare
is a traditional
Japanese blind made from bamboo. It has been used in Japanese
houses for a long time, especially
in summer. Its original function was to prevent direct solar
radiation from entering a room, and to introduce
outside air into a room at the same time.
As an element of building, Sudare has the other function of creating space for different
activities that need different levels of privacy. The characteristic
form of Sudare makes
it possible to see objects outside the house. During daytime, it is possible to see clearly
the outside environment
from inside but still maintain privacy from outside to inside. The
privacy level is determined
by the visibility level between each space, or from outside to
inside, which are separated
by partitions.
At the same time, Sudare as a shading device can
reduce thermal energy consumption.
This study aims to evaluate the effect of the diameter,
spacer, scale, and whiteness
of
Sudare on the level of visibility by comparing
people’s responses
by means of a questionnaire
using physical and digital images experiment with different conditions of illuminance level.
The results of the questionnaire using physical and digital image experiments indicate
that both the experiments showed the same trend. The illuminance ratio is the main
factor that affects the visibility value. A higher ratio of illuminance difference between
the observer’s room and the object room will increase the value of visibility. The physical
characteristics of Sudare (diameter, spacer, and scale) also influence the visibility value.
Small scale Sudare have a better visibility value in a low illuminance ratio whereas large
scale Sudare have better visibility value in high illuminance. High visibility value can be
achieved when the illuminance ratio is more than 4.30. |
