Zolang we het niet lokaal (op
gebiedsniveau) oplossen, blijven we
plunderen en stelen van andere
culturen. (nog steeds jagers en verzamelaars!)
WW I : The Dutch Island
During World War I The Netherlands was
thrown back on their own resources. And
after the sea war started no supplies
from overseas arrived anymore. It had
become an island .
1914 : export bans
(gold, fossil fuels, machinery,
transportmeans, basic foods, minewoods,
fertilizer)
1916 : Fuel rationing law
(coal ships plundering)
1917 : potato rationing law
(potato riots)
1918 : Land ripping law
Meat reduction measures:

If a system, whether defined as a building, city or the earth as a whole, consumes
more thermodynamic “quality” as being converted and stored from radiation,
somewhere depletion takes place and quality in the system as a whole decreases.
Or: If not balanced within system: Either steel from neigbors or deplete stocks

1 reorganiseren
3 separate sewer systems: black
water - grey water - rainwater ,for
easy treatment (Culemborg)
Efficient, but smart?
3 times infrastructure! A smart
resource solution –and resilient- would
be a compost-toilet system

MAss is more improtant, only energy is
suboptimising…
Geen A+++ C2C wasmachine, maar wasserijen,
met haal en breng service
3 billion new electrical cars:
What about resources and
embodied energy?
“Electric cars!”
1,5 billion new e-cars???
Keep the old cars and
replace engines:
Less resource problem,
massive (local) jobs….

Start reorganising,

stellingen
Er is nog nooit een nieuw gebouw
neergezet dat heeft bijgedragen
aan de absolute verlaging van de
milieu-impact .
Er is geen recht op huisvesting,
slechts op een gelijk aandeel in de
grondstoffen
We hebben doorbraak-processen
nodig, geen doorbraaktechnologieen. Die hebben we al
lang.
Duurzaamheid is een hol begrip
geworden. Het gaat om
volhoudbaarheid mbt energie en
materialen.
Er is geld zat, als je lokaal en op
gebiedsniveau verantwoording
neemt.
