Lighting related research topics
Prof. Jeong Tai KIM, the Director of
Center for Sustainable Healthy Buildings is
responsible for the whole research program.
And he also has been leading Group 1-1 in
conducting the whole of the research
projects on health-friendly control
technologies for indoor built environment.
Due to the limited pages, this section
describes two lighting related topics 1-1-1
and 1-1-2.
Topic 1-1-1 Development of sustainable
lighting control technologies for visual
healthy environment:
This research project recently developed a
refurbished version of conventional
daylighting system for the purpose of
maximizing its role for occupants’ visual
health and sustainability of the indoor
environment, dealing with basic
performance elements such as floor plan,
geometry, orientation, controls and glazing
materials. This research project proposes
an experimental configuration of external
shading device which can be applied to
apartment houses, promising the most
efficient performance with various
adjustments of control techniques. The
research project also investigates spectral
characteristics and intensities of UV rays
which penetrate into built environments,
revealing their harmfulness for occupants’
visual health. With newly-developed
advanced health-oriented visual system,
the research project aims toward the
expectation of an average 15 percent surge
in its daylighting and view performance /
an average 20 percent surge in visual
comfort / an average 20 percent attenuation
Information
in CO2 emission / an average 10 percent
surge in optical function of daylight.
Topic 1-1-2 Development of cutting edge
lighting technologies for healthy
buildings:
This study aims to contribute to creating
healthy buildings which improve both the
health of occupants and the carbon
performance of buildings using cuttingedge
natural and artificial lighting
technologies. In order to achieve this aim,
this study has developed advanced
daylighting devices such as an active
mirror type device, and also created their
performance prediction models on the
basis of field measurements, so that the
advanced devices can be easily integrated
into the design of architectural lighting
systems. Another outcome of this study is
the development of wavelength
controllable lighting systems, which
provide the spectral power distributions
that match closely with the sensitivity of
human circadian rhythms. This study will
also provide the prototype of sustainable
healthy lightings systems and their
operation manuals for various buildings
types.
