To add information on the subject, the following is from "Frank
Lloyd Wright The Masterworks" by Bruce Brooks Pfeiffer.
"To render the structure fireproof, the Imperial Hotel
was an all-masonry building, composed of reinforced concrete and
brick. The bricks had to be specially made because of their
unique design: the brickwork in the lower part of the structure was
filled with reinforcing steel rods and concrete, the upper bricks
left hollow to reduce the weight of the building. In lieu of
traditional heavy tile roofs, lightweight copper was used. The
structure and its form was planned to have a low center of gravity,y
with balanced loads supported by cantilevered reinforced concrete
slabs, a type of construction entirely new to the Japanese."

Also, in the same book, in a section on the Isadore J. Zimmerman
house (Manchester, NH) Re: "gravity heat". . . to paraphrase,
this was a term that Wright coined himself. It consisted of
coils of pipe beneath the concrete slab that circulate warm water,r
thus heating the slab, creating no drafts. Wright first discovered
this system during his sojourn in Japan. So, while not specific
evidence that the hotel had this kind of heating, it seems likely.
