What if…
homes used
very little
energy, just
because of
how they were
built?

6. Down to Earth design
What if…
everyone
could
participate
meaningfully

9. Down to Earth design
I believe
natural
buildings
have the
potential to
heal

10. Down to Earth design
What makes a
building natural?

11. Down to Earth design
NATURAL
BUILDINGS…
… use local
resources
… are non-toxic
… are specific to
their climate

12. Down to Earth design
How?

13. Down to Earth design
#1: START
WITH YOUR
SITE

14. Down to Earth design
Understand
Your Climate
• Do you need heat in winter?
Cool in summer?
• What are average temperatures?
• Are you in the Northern or
Southern hemisphere?
• Is it dry or humid where you live?
• Do you experience 4 seasons?
• What is your annual rainfall?
• Which direction do prevailing
winds come from?

15. Down to Earth design
Prioritize
Your Comfort
Needs
• Are you sensitive to
cold? Or heat?
• Do you avoid or thrive
with humidity?
• What extremes can
you handle if it means
using less energy?

16. Down to Earth design
Understand your
relationship with
the sun

17. Down to Earth design
Orientation
Matters
• South – low in winter,
high in summer
this side is uniquely
controllable!!
• North – no heat gain;
balanced even sunlight
• West – hottest side
• East – morning light

18. Down to Earth design
Build where
you need
improvement

19. Down to Earth design
STEP
LIGHTLY
ON THE
LAND

20. Down to Earth design
CREATE

21. Down to Earth design
WHAT DO
YOU HAVE IN
ABUNDANCE?

22. Down to Earth design
#2: UNDERSTAND
YOUR MATERIALS

23. Down to Earth design

24. Down to Earth design
INSULATION…
…slows down the
flow of heat

25. Down to Earth design
USE
INSULATION
WHEN…
…you need the
inside temperature
to differ from the
outside
temperature

26. Down to Earth design
INSULATING
MATERIALS
INCLUDE:
straw
hemp
clay-slip straw
pumice
cotton
wool
air

27. Down to Earth design
THERMAL
MASS IS…
…a battery that
stores heat energy

28. Down to Earth design
THERMAL
MASS can be
used to store
heat

29. Down to Earth design
THERMAL
MASS can be
used to store
coolness

30. Down to Earth design
USE THERMAL
MASS WHEN…
…you want to
moderate rapid
temperature swings
OR
to absorb & store
thermal energy

31. Down to Earth design
cob
adobe
clay plaster
lime plaster
rammed earth
earthen floors
stone
water
soil
THERMAL MASS MATERIALS INCLUDE:

32. Down to Earth design
BEST BET IN
A MIXED
CLIMATE:
Use insulation
& thermal mass
TOGETHER

33. Down to Earth design
1. insulate
2. insulate!
3. insulate!!!
USE STRAW TO:

34. Down to Earth design
1. absorb heat
(from heat source in
Winter; from air in
Summer)
2. moderate
humidity
3. create
breathable
finishes
USE CLAY TO:

35. Down to Earth design
#3: DESIGN TO
MINIMIZE
ENERGY USE

36. Down to Earth design
Effective use of
thermal mass +
insulation are
essential
PASSIVE
SOLAR =
FREE
ENERGY
