• Passive solar systems rules of thumb
• The building should be elongated on an east-west
  axis.
• The buildings south face should receive sunlight
  between the hours of 900 A.M. and 300 P.M. (sun
  time) during the heating season.
• Interior spaces requiring the most light and
  heating and cooling should be along the south
  face of the building. Less used spaces should be
  located on the north.
• An open floor plan optimizes passive system
  operation.
• Use shading to prevent summer sun entering the
  interior.
