<p style='margin-left:.5in'><font size=2 face="Times New Roman"><span
style='font-size:10.0pt'>The UK's Building Research Establishment's
"Office of the Future" is one Euro building that deliberately uses
voids formed into precast concrete floor/ceiling panels to distribute &
extract natural ventilation air, consciously activating their thermal
mass. These proprietary panels were invented & seem to be most widely
used in </span></font><st1:place><font size=2><span style='font-size:10.0pt'>Scandinavia</span></font></st1:place><font
size=2><span style='font-size:10.0pt'>; they create an undulating ceiling with
~10' period peak to peak, with 'waves' ~2.5' deep. A flat floor is cast
above, and air is driven by wind pressure between this floor slab and the lower
ceiling formed by the precast panels. Their curving shape lend themselves
very well to direct/indirect lighting fixtures suspended below the high points
of the ceiling; for both nat vent & daylighting purposes, sections
are oriented perpendicular to the exterior walls. The shapes tend to elicit
that 'WOW' factor from architects....</span></font><o:p></o:p></p>
<p style='margin-left:.5in'><font size=2 face="Times New Roman"><span
style='font-size:10.0pt'>As I say, these are a proprietary precast system, but
the manufacturer's name escapes me at the moment. For more information,
speak to Feilden Clegg Architects (London, UK?) or the BRE; David Lloyd Jones'
book "Architecture & the Environment - Bioclimatic Building
Design" has both lovely pictures & (hail Mary!) monitored energy

air distribution systems (for want of a better term). I seem to remember
reference to a building that had the air distribution integrated into the floor
slab at one of JE Braun's presentations on building mass thermal storage. The
idea was to more effectively couple the air system with the building's thermal
mass. I know some related work has been done with raised floor systems over
concrete slabs but that's not really what I'm thinking of. </span></font><o:p></o:p></p>
