Carlos,
I read that in this University Hospital the corridors linking
the different wings are protected with screens to diffuse
the dazzling light and ensure natural ventilation, letting
the air flow through the perforated blocks to control the
high tropical temperatures. Though this building was
finished in 1954 it seems to me very up to date considering
all the new "green" architectural method we need to deal
with nowadays.
In any case I also admire very much the fantastic display
of bright colors so uncommon in a Hospital.
Thanks.
R
