Ecological fingerprint related: how much does your house weight? -
https://www.moma.org/collection/works/804This means, that since 1927 we know that for each capita in the industrial world for home construction there is the material weight need about 3000 Kg /1600 sqft (~ 149 sqm) divided by 8 inhabitants= 375 Kg.Why "8 inhabitants": Federation of American Scientist : starter family 32-38 square meter and expanded family 72-78 sqm, ergo a 1600 sqft house a " two expanded families home" representsThe "dymaxion building" production costs 2018 with Computer-Integrated-Machinery, also called AI-Technology,
less than 10.000 (ten thousand) US$, calculating with 1 US$/Kg Aluminium costs( 7,5 KVAh e-consume per Kg Alu= 1/2 electricity consume production process and 2,5 US$cents/KVAh electricity costs) for 149 sqm living area = 10.000 US$/149sqm~ 67,1 US$ per sqm floor area construction or for those thinking in squarefoot : 6,25 US$/sqft. Not more but also not less than their production costs target per sqm building construction :
