First Approximation Materials Requirements Palaces for the People ====================== There are no blueprints or engineering studies for the as yet hypothetical Palaces for the People. A totally arbitrary figure of one hectare was assumed. This figure was derived from the fact that it is similar in dimensions to average square city blocks in many cities. Since most people do not have intuitive grasp of many common metric units, adopting a standard square hectare size and shape allows residents and neighbors to have a "yardstick" to judge what a hectare really means. For a similar reason, 3 meters height per floor was adopted, again totally arbitrary. A working figure (perhaps to be modified extensively as planning progresses) of six stories or floors was adopted. The floor areas are numbered from the ground up, and the enclosed portions of lot area are as follows: Floor 1: 100%, 1 hectare = 100 meters by 100 meters, Floor 2: 100%, 1 hectare = 100 meters by 100 meters, Floor 3: 64%, 80 meters by 80 meters, Floor 4: 36%, 60 meters by 60 meters, Floor 5: 16%, 40 meters by 40 meters, Floor 6: 4%, 20 meters by 20 meters, -------------------------------------- total FAR 3.2 (Floor Area Ratio to lot size) 3.2 hectares of interior floor space, gross figure, does not take into account wall thicknesses subtracting from usable space, other adjustments, etc. There is also one basement of yet to be determined size, and perhaps sub-basement rooms for infrastructure. Building is constructed of load-bearing walls and pillars, supporting spanning trusses. The initial goal is to calculate a rough figure of materials needed to build the structural shell, so as to acquire an initial ballpark estimate of materials costs. These are pure materials costs, not counting labor for construction. The idea is to get some idea of the fixed-costs of building a structure. For interim working figure, a value of 1/3rd costs are assigned to materials, 1/3rd to construction labor, and 1/3rd to land acquisition, financing, permits, fees, etc. If somebody has better information which can make these numbers and values more accurate, please speak up without delay. "It is interesting that at the present time, twenty-two years later, the U.S. government is specifying in its bids for space structures the octet truss (my copyrighted trademark name) for all the main structuring for space stations" _Buckminster Fuller The Octet Truss is considered strong enough to service in the most hostile environment human beings have ever entered (vacuum space), but is not in common use in large public buildings. Buckminster Fuller introduced the Octet Truss, which he called the isotropic vector matrix. http://www.grunch.net/synergetics/octet.html http://www.grunch.net/synergetics/ivm.html http://www.tabletoptelephone.com/~hopspage/Fuller.html http://reality.sculptors.com/~salsbury/Gifs/Graphics/octet-truss-003-v1.png Here are pictures of the Museum of Modern Art Fuller Octet Truss exhibit. http://www.synergeticsinc.com/bodytext/Moma.htm http://www.synergeticsinc.com/bodytext/exhibit.htm sidebar: reinforced pozzolana-crete ---------- "Appropriate Use Of Pozzolana Derived From Appropriate Use Of Pozzolana Derived From Agro-waste Using Labour-Based Appropriate Agro-waste Using Labour-Based Appropriate Technology Technology" <URL Begins> http://www.transport-links.org/transport_links/ifg/CD%202/IFG_presentations/Minimising%20the%20Cost%20of%20Sustainable%20Rural%20Access/Pozzolana%20From%20Agro-waste%20Using%20Labour-Based%20Technology.pdf <URL ends> (If the Cambodians can produce Pozzolana on villiage scale labor-based appropriate technology, what's your excuse?) ----------------------------------------------- The Octet Truss is a gender-friendly construction method which does more with less. Capable of being built indoors in any weather as components of prefabricated units, Octet Truss modules can be built onsite or pre-fabricated offsite prior to final assembly. Using less than a tenth the steel content, the Octet Truss dispenses with enormous quantities of mass and weight which otherwise impose crushing burdens on lower supporting floors. One-tenth the weight, twice as strong. It is a strenuous burden on contemporary imaginations to conceive of a society with ample solar energy available. Palaces, equiped with one or two megawatts of daily power, converting some into electrolyzed hydrogen gas (H2), will have both electric and gas available for welding, smelting, and foundry work. Solar PV Breeder farms will generate so much solar PV electricity that they will breed more solar PV panels, hence the name. The refuse of a Palace will go down the gullets of furnaces: glass to become glass fibers (fiberglas reinforcements, lightpipes, data conduction fibers) or glass bricks, or further purified to become SOG PV feedstock, steel cans will be melted into rebar rods for Octet Trusses, aluminum cans will be melted for refabrication into solar panel support structures, and as wire for electrification purposes. The synergies between the Palaces, the Solar PV breeders, and the ecosyn microfarms will produce a virtually wasteless society. This is the development and prototyping project that the small working group has signed on for. Computing the least amount of materials sufficient for Palaces and PV Breeders, plus computing the reliable food security of microfarming techniques, is the immediate tasks at hand. The tasks themselves dictate some of the sequences of procedure. Speak up if you notice anything too vague or out of proper order.
