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

2- Overhangs and Shading

Five Principles Of Design:

1- Orientation

4- Windows

3- Insulation

5- Thermal Mass

OrientationBuild within 15 degrees of

South

Right shape and proper window placement

Longer dimension of the building faces south

Hills, Trees, Neighbors

Consider your terrain:

Properly laid out and designed, a passive solar home can cut the

building’s energy use up to 30-40%

overhangs and shading

The temperature inside a building may increase as much as 20 degrees or more if E-

W windows and walls are not shaded.http://www.consumerenergycenter.org/home/construction/

Landscaping: Trees, vine covered trellises

Shade: insulated drapes or shutters, exterior shades, awnings.

Overhangs: Summer/Winter Sun Angles70/30 degrees

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

Who knows what savings lurks in the depth of the shadows?

InsulationYou can be too rich or too poor, but

you can never have enough insulation.

“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

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

Passive Solar Window Areas10% south side to building areaLimited north and west windows

Double-paned Low-E windowsLet the sun’s radiation IN and use shading in hotter

monthshttp://www.greenhomebuilding.com/QandA/solarheat/glazing.htm

Thermal Mass

Thermal mass on the interior absorbs the heat and radiates it back at night.

Thermal mass is a solid or liquid material that will absorb and store

warmth until it is needed.

What truly sets a passive solar home apart from a traditional home is the thermal mass.

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.
