hardly anyone, it seems. although this professional engineer designed
many of them in cold, cloudy new england and other places since about
1946. he's the very first recipient of the annual american solar energy
association's passive solar pioneer awards, but when i noticed a recent
article in an ases magazine describing yet another direct gain house with
mediocre performance in glowing terms and called the writer to suggest
a story on norman's houses, he said he had never heard of him... :-)
norman would be about 85 now, and i have the impression that
he is no longer designing houses.
>i have a book on them written by william a. shurcliff...
"super solar houses." you might also look at shurcliff's "new inventions
in low-cost solar heating" and "thermal shutters and shades" and "super
insulated houses and air-to-air heat exchangers." dr. shurcliff would be
about 92 years old now...

he typically used about 10k pounds of water in sealed containers
in the attic (with prefab trusses designed for that weight) and 20k
pounds of rocks in the basement. the roof was a "staircase" with several
layers of vertical glazing and horizontal external glass mirrors
to triple the wintertime solar intensity. he also suggested glazing
the whole exterior south wall of a house (with an air gap and a dark
surface behind the areas without windows) to collect warm air that
would rise up into the attic and provide further heat for the water
containers, which were smallish (3 gallons?) for better heat transfer
between the water inside them and the air outside them.

not exactly, as i recall. having active hot and cold stores available
makes for good house temperature control, as in a push-pull amplifier
or a cmos ic. to warm the house, circulate air between the house and the
attic, and circulate air between the house and the basement to cool it.

yes. there are some new techniques and materials and weather data.
we might improve these 100% solar heated houses by reducing the cost
or the cost of the electrical energy needed to operate the fans or
the yearly maintenance, eg topping up water containers, which are not
hermetically sealed, or by improving their room temperature control
or by reducing the amount of thermal mass needed or moving it out of
the attic, in earthquake areas, to improve safety.

perhaps someone has a complete list of his houses and schools and
churches and other structures...
