Using shipping containers as housing for
people with environmental illness
by J. Camphill
There are millions of
shipping containers in circulation, transporting goods over long
distances. Many shipping companies
choose to sell off some of their older containers instead of sending them back
to China empty.
It seems an enticing idea
to use an old shipping container as safe housing for the environmentally
ill. After all, itÕs pure steel, a
reasonable cost and also transportable.
However, itÕs been tried and it doesnÕt work well.
I know two people who
tried, and both gave up. The main
problem is that each time the shipping container enters the United States, it is fumigated to prevent exotic bugs from entering
the country. All sorts of toxic
products being shipped inside have added to the contamination. ItÕs been tried to decontaminate them
with ozoning, scrubbing with chlorine and other cleaners, etc., etc., etc. In both attempts, it was a complete
failure.
Another major problem is
that such a container is extremely poorly insulated. It gets very hot sitting in the sun and very cold on a
winterÕs night. In a desert
climate, it can be both brutally hot and brutally cold within the same 24
hours.
To insulate the container
it would be necessary either to build an insulated shell around it, or insulate
it on the inside. A durable
exterior insulation would be costly and make transport more difficult.
Insulating
on the inside would typically be done by putting up studs, insulation and
drywall. All three cause problems with the
indoor air quality. Steel studs
can be used, but they will reduce the insulation value dramatically (thermal
bridging). Drywall can be sealed,
but that can trap moisture between the drywall and the outer steel wall,
creating mold and fungus problems.
A porous sealer will be necessary — and less effective.
The expense for
electrical wiring and plumbing is a major part of building a house, and will be
the same as for a conventionally built house of the same size.
The final product may end
up costing nearly what a small built-from-scratch home would cost.
Windows would need to be
cut in the sides. They can only be
small, if the container is to be moved again. Large windows will weaken the box, so it may be damaged when
lifted.
The steel walls would
provide some shielding from outside radio-frequency radiation, but any
electronics used inside will be more troublesome as their radiation will simply
bounce back from the steel walls.
Many people with electrical sensitivity do not do well in a metal box,
especially if the floor is metal.
Shipping containers seem like a good solution to the MCS and EHS housing crisis, but they arenÕt.
