TYPICAL

Geographic
position,
season
and
weather
conditions.
When
looking
at
the
effects
of
natural
daylight
in
offices,
the
place
on
earth
where
an
office
building
is
situated
is
of
course
one
of
the
key
factors.
Where
an
office
is
situated
is
of
significant
importance
in
terms
of
natural
daylight,
hours
of
sunshine,
angle
of
incidence,
intensity
of
solar
radiation
etc.
It
is
the
latitude
of
the
place
on
earth
where
an
office
building
is
situated,
combined
with
the
effects
of
the
seasons,
that
determines
the
maximum
height
of
the
sun
over
the
horizon.
The
height
of
the
sun
over
the
horizon
determines
the
angle
of
incidence
of
solar
radiation,
which
in
turn
has
an
important
impact
on
the
perception
of
visual
discomfort
caused
by
it.
Of
course,
the
luminance
of
the
sky,
the
illumination
of
the
window
and
the
surroundings
and
the
intensity
of
the
natural
daylight
also
vary
according
to
weather
conditions.
A
clear
sky
has
a
different
luminance
from
an
overcast
sky,
and
white
clouds
illuminated
by
the
sun
may
cause
more
glare
than
direct
sunlight.

Façade
Orientation.
A
north-facing
façade
in
the
northern
hemisphere
will
not
be
directly
illuminated
by
the
sun.
Here,
one
should
try
to
exploit
the
benefits
of
natural
daylight
to
the
maximum,
as
glare
problems
are
minimal.
Verosol's
transparent
fabric
types
are
typically
suitable
for
these
facades.
East,
west
and
south
facing
facades
are
directly
illuminated
by
the
sun
to
a
certain
extent,
depending
on
aforementioned
variables,
such
as
latitude,
season
and
weather-conditions.
Here
semi
transparent
and
non
transparent
materials
are
usually
required
in
order
to
provide
sufficient
protection
from
glare.
At
the
same
time
however,
they
reduce
the
view
to
the
outside,
and
therefore
impair
having
a
meaningful
contact
with
the
world
outside.
Verosol's
day
&
night
blinds
are
a
perfect
solution;
they
combine
a
transparent
and
a
non
transparent
fabric
in
one,
fully
operable
blind.
This
enables
the
occupants
of
any
office
to
make
their
own
choice
as
to
the
optimum
compromise
between
glare
reduction
and
view,
depending
on
all
the
mentioned
parameters.

Buildings
opposite
the
office.
A
factor
of
influence
when
addressing
the
issue
of
visual
comfort
is
the
environment
of
an
office
building,
and
more
in
particular
the
presence
of
other
buildings
in
the
field
of
view
of
the
occupant.
Such
buildings
can
obstruct
the
luminance
of
the
sky
and/or
sun,
and
therefore
reduce
the
risk
of
glare.
At
the
same
time
however,
if
buildings
opposite
the
office
have
mirror-glazed
facades,
they
could
increase
the
risks
of
glare,
even
in
north-facing
offices.
The
south-facing
façade
opposite
the
office,
could
in
this
case
reflect
the
sun
and
cause
very
high
luminance
levels,
resulting
in
blinding
or
glare.

countries
in
the
southern
hemisphere

for
south

vice
versa.
