This
study
aims
to
investigate
the
characteristics
of
energy
consumption
and
outdoor
thermal
comfort
within
high-density
urban
fabric
Changsha.
Two
different
types
building
(residential
office),
as
well
three
forms
(point,
slab,
enclosed)
were
analyzed
under
local
climate
zone
scheme.
Utilizing
ENVI-met

software,
simulations
conducted
assess
144
architectural
models.
Then,
multiple
regression
spatial
applied
predict
area.
The
results
showed
following:
(1)
In
area
Changsha,
central
business
district
historic

adjacent
Xiangjiang
River
are
identified
areas
with
high

intensity.
(2)
Among
residential
categories,
point-types
LCZ-3
LCZ-6,
slab-type
LCZ-4,
exhibit
lowest
contrast,
enclosed
office
buildings,
LCZ-2
LCZ-5,
characterized
by
highest
(3)
Urban
form
parameters
such
floor
ratio
shape
coefficient
have
a
significant
impact
on
EUIwinter,
while
EUIsummer
is
highly
related
normalized

vegetation
index
(BSC).
(4)
LCZ-4
stands
out
its
notably
lower
cooling

intensity,
coupled
excellent
comfort,
making
it
particularly
well-suited
for
climatic
conditions
