about heat, fans and ironstoves...

Patrick, are/were you then a professional and/or journalistic photographer?
 
was still some twenty years ago, not anymore. I quit some years after
migrating to plant trees here... :-)

Are there many other (historical) places in the world you photographed?

only , basically ,  european /belgian , but was not  strongly interested in
buildings in those times.
I loved symmetrical or the like objects.
 
Is there anyplace where one can readily see your work?

exception made of few exhibitions, in the same 70ties, not now.
was not very interested in "publishing".
have some (?) box(es) of  picts, but not yet thought of some www site to
"show" them. 
will think about, but  need to check the scanner (not much used those times)

ps
I can still remember the first moment I entered St. Peter's August 1977 in
that the air was as if air-conditioned--the temperature differential from
outside to inside was quite dramatic. The explanation was that all the
massive masonry of the basilica was still radiating inwardly all the
coldness it had absorbed during the cold months a half year earlier.

not sure. how do you explain that phenomenon in Mexico inside of similar
buildings? If the wheather is generally always  warm if not hot in some
places like Chihuaha or Torreon?
And inversely, if the St peter Basilica was still fresh in summer, why
aren't the walls , on the contrary, radiating heat  in winter, six months
after the summer ?

I would suggest ( not an architect here... more an engineer) the inside
height of the coupole  -- or the Nave (?)(Y la Nave va...) or "la nef" as an
esquif  "cruising the air" , not the see  ---   can produce  a current of
air towards the upper parts, convecting such hot ( or warmer) volume  of air
from the ground level to the roof, or the "coupole".
The roof level of st peter can be very hot, eventually hotter than the
outside air, for accumulation process,  but the ground level isn't.  The
"coupole" radiates the excess heat to the outside  volume, for being  made
with thinner  ( eventually lighter ) materials , evetually as copper ( Many
buildings repeat such idea, Bellas Artes in Mexico City, many churches (St
Paul in London, I think , also has a copper dome. St Marc basilica in
Venice.
So supposing I'm right, the lower  walls are much thicker, and the inside
part of suchwalls , if "heated" just a little bit by ambient air or
progressive transmission of heat trought the same wall, looses easily such
calories from the "inside" "crust" of warmer  material  to the interior
volume of air  inside the building, which goes up where it  heats the
coupole, wich later on is always hotter than the external ambient air to
wich such coupole  easily exchanges the heat accumulated from the inside.
The coupole is like a radiator, if i'm correct... and  so the lower part is
kept colder. 

Eventually dilatation problems , if existing, let's say in the Washington
Congress Dome, or similar buildings, could be a verification of this
theoretical point....
btw the  US congress coupole, if i remember correctly, was relativey hot in
the winter i visited it.
I suppose the heat was on... it wasn't a reversed radiation of  some heat
accumulated inside the  walls in the past summer, but could be the  heat
from the fireworks or the vocal energy from the vigourous interventions of
all the members during the C-spanned sessions...
(just kidding..)

If  you worked inside the Sixtine to restore the Paintings , i think you
would agree. relatively hotter on the scaffolds than at ground level.
fans needed  (to move air,  or even to applause such work and clap hands
......)
(why are fans (mean  the spectators) named  like some ventilators in english
?) 

( I have some knowledge about
heating/convection/conduction/radiation/chimneys processes, for collecting
/restauring old irons stoves for many years...) so i  learned to chop trees
and use those thermodynamics notions or phenomenons to try to reduce smoke
inside the house.... Applied science !  :-)
