ABSTRACT: In the subtropical zone of China, a large number of old factory buildings
rich in industrial historical and cultural value have been transformed into art
studios. In the existing research on building renovation, there are still
problems such as insufficient lighting, low uniformity, and ignoring the effect
of glare in the lighting environment of buildings after transformation. To fill
this research gap, this paper provides a daylighting design strategy for these
factory buildings in subtropical zones to ensure that the transformed art
studios can offer an excellent indoor daylighting environment. Through the
control variable method, the window-to-wall ratio, the form of external
windows, and the visible light transmittance of glass are set with quantitative
and variable values, and a design strategy that meets the requirements of
international general daylighting standards is obtained step by step through
the simulation. The daylight factor, uniformity, daylight autonomy, and dynamic
glare probability are used in this research process to measure whether the
daylighting strategy meets the daylighting requirements of the CIBSE Lighting
Guide for art studios. The results show that the average indoor lighting
coefficient can be increased from 1.29 to 6.18, and the minimum value of the lighting
coefficient can be increased from 0.4 to 4.4 by enlarging the windowed wall
ratio from 1:30 to 1:3, using the combination method of the horizontal window,
skylight and skylight recommended by the analysis results, and selecting veneer
glass with 88% transmittance. This allows for better uniform lighting inside
the building and reduces glare. This conclusion can support the lighting
performance design of industrial buildings in the future.
