Passive solar design
Use of the natural
movement
of heat and air
to maintain
comfortable temperatures,
operating with little
or no
mechanical assistance.

Passive Solar
is the
aikido of building design
Aikido leads towards the integration of mind, body, and spirit towards making us complete human beings,
which not only benefits us,
but benefits the people around us.
Everything in Aikido training is meant to develop
not only a strong individual, but one with the wisdom
and energy to positively benefit society.

Passive solar design
Five Principles Of Design:
1- Orientation
2- Overhangs and Shading
3- Insulation
4- Windows
5- Thermal Mass
WWW.GreenPassiveSolar.com
Orientation
Build within 15 degrees of South
Consider your terrain:
Hills, Trees, Neighbors
Longer dimension of the building faces south
Right shape and proper window placement
Properly laid out and designed,
a passive solar home can cut the building’s
energy use up to 30-40%

overhangs and shading
overhangs and shading
Overhangs: Summer/Winter Sun Angles
70/30 degrees
Shade: insulated drapes or shutters, exterior shades, awnings.
Landscaping: Trees, vine covered trellises
The temperature inside a building may increase as
much as 20 degrees or more if E-W windows and walls
are not shaded.

For a tight budget, think of south and west shading as
a priority.

Insulation
You can be too rich or too poor, but you
can never have enough insulation.
Richard Komp
“Flipping” a house or building for the long-term.
Passing your stewardship on to the next person,
and generation.
The best way to predict your future
is to create it.
Windows
Passive Solar Window Areas
10% south side to building area
Limited north and west windows
Double-paned Low-E windows
Let the sun’s radiation IN and use shading in hotter months

Low emissivity glass can increase energy savings by 15 - 30%

Thermal Mass
What truly sets a passive solar home apart
from a traditional home is the thermal mass.
Thermal mass is a solid or liquid material
that will absorb and store warmth until it is
needed.
Thermal mass on the interior absorbs the heat
and radiates it back at night.

Change occurs
at the speed of thought
If you can’t afford solar panels,
you can afford new and retrofit solar design.
We can no longer not afford to build sound solar
principles into all of our housing projects.
Be a part of the solution for long-term
environmental sustainability - there is no place
like home.
