Permaculture Approaches to

The Built Environment

Bill Note on how to deliver this:

1.
Start with opening slides up to Cal
-
Earth

2.
Then show various
youtubes

on building alternatives

3.
Back to slides here

4.
Show

1.

3.
Walls & Floors
(Thermal Mass
vs
…… insulation
)

4.

The Rubble
Trench


A favorite of Frank Lloyd Wright



Dig trench 4 inches deeper
than the frost line.


Lining trench with
landscaping fabric
before backfilling
minimizes silt
washing into gravel.

Tamp in 4 inches of washed gravel and set in perforated drain tile that slopes
to one corner. Must gravity feed away from building.

Creative alternative to
plastic drain tile.

Fill trench with clean
gravel, tamping
regularly for solid
compaction.

The stem wall or grad beam can be poured
with reinforced concrete. This gets the build
above grade and away from moisture.

Earth bags can be
used as well.

What is a moldering toilet?


A moldering toilet is simply a waterless toilet that is
built to allow for very long term slow decomposition
in place


the waste molders, rather than composts,
much as leaves and plant debris "molder" on the
surface of soil through the action of bacteria, fungi,
and microorganisms.


This “technology” for waste treatment is isolation and
time itself!
