True I was mostly basing my numbers of the necessity of the ceiling height
not on the usable space in between. I definitely agree something is out of
whack but have changed my mind on a few things after giving them some
1. The height of the plenum area can be much smaller than it is today.
Currently the majority of the need for space there are the air movers and
returns that help circulation. High velocity air cooling/heating takes a
much smaller space (tube usually inch in diameter or so) to move air.
2. multiplexing and bundling of fiber cabling could vastly reduce the
amount of cabling required in this area especially since it requires no
special shielding for being next to power cables.
3. hmm... hidden ceiling space = security risk. plenty of military
installations require cabling to be run visibly on the walls rather than
enclosed so as to expose sniffing devices and what not. Not to mention the
danger of having a merc hiding in your ceiling just waiting for the morning
whistle to blow.
I think given possible future advancements in building design the plenum
area could be reduced to .3 meters. This plus .2m steel beam honeycomb
structure and on top of that .1m plasticrete slab. Call the ceiling height
.5m total and we are golden. Do with the rest of the space what you will.
