Rainwater Harvesting for Drylands and Beyond by Brad Lancaster

Sun-Path Illustrations (southern hemisphere)

Here on Earth we experience seasonally changing paths of the sun across the sky. The more aware we are of how this plays out where we live on the planet, the more effectively we can design in cooperation with the sun for free passive winter heating & lighting, summer cooling & shading, and solar-power systems that are productive year round.

Take a look at Rainwater Harvesting for Drylands and Beyond, Volume 1, 2nd Edition, for many examples and strategies that make good use of the natural path of the sun, along with tips that enable you to do the same.

The following illustrations show the summer- and winter-solstice sun paths for latitudes 0º, 12º, 23.5º, 32º, 44º, 56º, and 68º in the southern hemisphere.
