Green Building: Finding True South to Optimize Orientation

Petrangelo_001_1

You may have already heard that House & Garden Magazine took a green approach in its latest installment, the February issue I believe.  One article talks about an interview with William McDonough, in which he mentions the orientation of a home.  Earlier, I blogged about Global Green USA’s Top 20 list of low- or no-cost green building strategies and orientation was #1.  Regarding orientation, the rule is to "orient a building to maximize natural daylighting."  As part of the orientation process, one needs to find a building’s true south and build it in such a way, to maximize sun exposure/non-exposure, and thereby, optimize energy-efficiency (i.e., use the sun instead of artificial lighting, use the sun’s warmth instead of heating, use the shade’s cool instead of air conditioning, etc.). 

McDonough pointed out that many architects and builders don’t know how to find true south.  If a compass is used, the compass indicates south, which can differ from true south by more than 15 degrees.  Remember, orienting a home is about orienting the home to sun exposure, not magnetic south.  To find true south, one needs two things:  (1) to know your geography’s solar noon, and (2) to use the sun to draw perfect north/south line exactly at solar noon.  Solar noon is the time when the sun hits the highest point in the sky and can be found using the following Sunrise/Sunset Calculator.  Once the solar noon is figured out, take a line with a weight attached to it, hold it up in the air at solar noon, and the shadow line will reveal the proper north/south orientation of a home.  That line will point to true south and will help you build the home properly, assuming you have some latitude in deciding the orientation of the home.

Beauty.  Simplicity.  Green Planet Paints (GPP) has developed an interior house paint that sets a new standard for environmentally responsible paint.  Using natural, renewable plant and minerals sources, GPP has created a soy based resin to replace the use of petrochemicals in paint, creating an innovative, zero VOC paint. They have also replaced the harmful dye coloring system with clay color pigments.  The results are a paint built and manufactured by sustainable principles that surpass conventional paints in performance and color.  Green Planet Paints are recommended for interior wall surfaces and come in exotic and earthy colors.  Green Planet Paints can be purchased at select retail stores or on the website.  Nancy Haecker can be reached at nancyhaecker [a] earthlink dot net.

I was in Utah over the weekend for Equity Green‘s wedding.  He’s a real estate tax guy named Garrett, so visit the archives if you want to learn about green real estate from that perspective.  While in town, I picked up Utah Business magazine, which included an article on the state’s 2007 Economic Forecast, and I noticed a list of the Top 100 Fastest Growing Companies [Registration required].  Guess who was on the list as the state’s #22 fastest growing companies?  3Form.  The magazine says 3Form is company that "creates resin products for design and construction industries."  More specifically, 3Form is committed to environmental solutions for their industry and was recognized by BuildingGreen in 2006, for having a Top-10 Green Building Product.  I’ve written about both 3Form and the Top-10 Green Building Products list previously at the links above.
