Abstract:
Karachi
is the
only
metropolis
in
Pakistan,
and in
the last
two to
three
decades,
there
has been
a
continuous
increase
in the
daily
average
temperatures.
Consequently,
there
has been
an
average
increase
of 4% to
6% in
the
annual
temperature
over
this
period.
The main
reasons
for this
rise
could be
an
increase
in
cementation
and a
reduction
in green
areas
due to
abrupt
and
unplanned
construction
in the
city. To
verify
this
statement,
we
devised
a
simulated
solar
heat
energy
experiment
tailored
to the
environmental
conditions
of
Karachi.
This
experiment
was
carried
out in
both
open and
covered
areas.
The
findings
of the
study
outcome
indicate
that the
heat
energy
retained
in the
environment
has
increased
due to
cementation,
reduced
green
spaces,
and the
population
increase.
An
average
increase
of 3.5
°C was
recorded
during
the
experimental
procedure.
