those in the West District Sutra Hall. The internal atrium,
located on the south side, measures 7.8 m × 5.2 m. The
vent, measuring 1.2 m × 2.0 m, is located in the middle
of the eastern ceiling. The sunroom is cantilevered outside
the main wall and connected to the East District Sutra Hall
through an archway, with all of its walls made from thin
wooden panels.
The printing space is located on the northwest side of
the building, with an overall height of 4.9 m. This space
allows direct air exchange with the outdoors through the
internal atrium that opens to the roof. Apart from the
column structure, wooden shelves are placed along the
walls, with the printing work area situated in the center.

Drawing by Zhong (created with SketchUp) features of the DSPH can be summarized. These features
include higher floor heights, internal and external atriums,
numerous windows and vents, a sunroom, a variety
of structural materials, a thick roof, and a distinctive
architectural layout.

3.1. Method
This research mainly adopts the methods of 3D laser
scanning, field testing, and CFD numerical simulation. 3D
laser scanning is used to capture the building environment
and create a digital model of the DSPH, which provides the
necessary data for wind environment software simulation.
During field visits and physical environment testing at the
DSPH, the meteorological characteristics and architectural
wind environment performance of the region are observed
and analyzed. The collected data serves as input for the
