Schol clasrom is a place where students stay most of the time during the day for education, which esentialy
neds pleasant lighting environment. However in reality, there is inevitable unbalance of Daylight caused by the
depth of the clasrom. There already were some solution that has ben sugested to solve this problem like light
shelf, but these solutions also has problem of uneficient space use, dificult in emplacement, etc. So in this study
we have sugested a beter way to improve the light environment in clasrom using a lighting tol caled ‘Venetian
blind’,which doesn’t have any problems we mentioned before. We have sugested an alghrithm that can give
us the best angle for each slat in Venetian blind depend on time and few conditons in clasrom, and we have
proven the alghrithm using Radiance simulation, and Mock-up in test-bed. Algorithm was made to give the angle
of each slat in blind, where blind can concentrate the Daylight to the table which is furthest from the window.
We have made the alghrithm by backtracking the Daylight when blind is set to the best angle we want, and made
an equation of the angle we want.The result of simulation and the test in real clasrom is as folows. First, we
have observed that light environment has improved in al seasonal days using the Venetian blind with this study’s
algorithm. Second, as we have tested the Venetian blind with algorithm in real test-bed, we have observed that
luminance has decreased in 2.6 times in table which is closest to the window. This means our algorithm has achieved
the goal of reducing the glare which students that are placed closest to window fels. Third, when using the blind
with this study’s algorithm, we have observed that luminance in furthest table from window has increased in
more than thre times, and by using the blind with this sruty’s algorithm, schol can save energy use up to 3.2×10(9)J(87%) per one clasrom.
