Dive into Earthships: Sustainable, Eco-Friendly Dream Houses
INTRO TO
EARTHSHIPS
Self Sustainable, Eco-
Friendly Dream Houses
▪
“An understanding of mechanical
systems for most humans is limited to
what is within reach of their fingertips. It
is understood that when you flip a switch
on the wall, a light comes on. When you
turn on the tap, hot water comes out.
When you pull the handle on the toilet, it
flushes. Little thought is given to where
the electricity comes from or what kind of
nuclear waste was produced to generate
it. How many of us even know where the
power plant is that supplies our power?
Few people ever wonder which water
table is depleted to bring them water and
what chemicals have been added to it.
Where does the sewage go after it is
flushed and which rivers and lakes are
polluted by it?”

Absorbs heat by day, radiates
it back out at night
Home must be south facing for
max efficiency
Right thickness of thermal
mass is key.
•
Too thick = heat being lost
into extra mass
•
Too thin= not enough
storage
Earthship Brighton had 2m
walls
Too thick!
When using thermal mass in
floors, they must remain bare

Must be custom made! Most
expensive part, also most
important.
Takes 3 months to be made
Traditionally at 90 degree angle
to sun
This will cause more wearing of
windows and beams
A rating is best.
U-value: how much heat can
travel through the material
R-value: how much sun light can
pass through
You want LOW U , HIGH R

Compressible in inner

Many varieties!
Cooling
Passive Cooling

Passive

Hot air rises
Cold air sinks
Custom windows allow for cool
air flow through bottom trap, and
warm air to escape through
upper ventilation traps
Better insulation = less infiltration
Be aware of wind flow in your
area
Having bodies of water nearby
helps!

Basic principles Heating & Cooling Power Generation Water Harvesting Waste Management Food Production Building with Recycled Materials
Passive Solar Heating Rocket Stove Radiant Floors Insulation Heating
Passive solar heating (1) Thermal Mass: Any material that helps you store the sun s heat. Usually very dense earth. Absorbs heat by day, radiates it back out at night Home must be south facing for max efficiency Right thickness of thermal mass is key. Too thick = heat being lost into extra mass Too thin= not enough storage Earthship Brighton had 2m walls Too thick! When using thermal mass in floors, they must remain bare
Passive Solar Heating (2) Glazing: Layers of glass arranged to allow maximum light in, while also keeping heat from escaping Must be custom made! Most expensive part, also most important. Takes 3 months to be made Traditionally at 90 degree angle to sun This will cause more wearing of windows and beams A rating is best. U-value: how much heat can travel through the material R-value: how much sun light can pass through You want LOW U , HIGH R
