Benefits of Passive Solar Systems

There are currently 4 methods of using solar energy. They are Passive, Thermal, Photovoltaics and Thin Film. This site gives benefits to each type of solar energy. http://www.solarpowerathome.com/advantagesofsolarenergy.html

Passive solar power is energy that is collected by manipulating an environment to make the best use of the solar rays that fall on the property more.

This link shows the Benefits of Passive Solar vs. Traditional Design when designing a solar building. Three things to keep in mind are that:
A)The strongest sunlight comes from the south
B)Sun exposure provides heat as well as light
C)Walls must have proper insulation to retain the heat generated by sunlight after the sun goes down.
This document analyzes two public library buildings of similar size - the study concludes that orientation;sun shading; and day lighting are responsible for 13.9% savings in energy use. Also, increasing the effectiveness of the envelope could save another 46.8% in energy use.
