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. http://www.consumerenergycenter.org/home/construction/solardesign/index. html http://www.aikidoconnection.com/aikidobenefits.html

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% http://www.consumerenergycenter.org/home/construction/solardesign/orientatio n.html

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. http://www.consumerenergycenter.org/home/construction/solardesign/overhangs. html

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

Low emissivity glass can increase energy savings by 15 - 30% GREAT SITE: http://www.bae.uky.edu/energy/residential/guide/guidehtml/guidep53.htm

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. Site for great pictures: http://passivesolar.sustainablesources.com/

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.
