Passive Solar Design Simplified Presentation
Transcript of Building orientation
  • Nothing above 15deg to the south ,using the Solar Pathfinder
  • Long side within 15deg of true south
  • Using most of the glass facing south
  • Minimize glass on east and west to avoid summer heat
  • A great strategy is to plant trees on east and west
  • Block the high summer sun externally:X~ltitude+20deg
  • Allow the low winter sun in Y>=sun at solstice
  • Make use of:roof overhangs,trellises,awnings,external shutters,louvers and arbors
  • Use dense material inside a building to store heat energy
  • Thermal mass is most effective when spread out,in walls and located in direct sunlight
  • Use at least 3-9SF of 4”thick thermal mass per SF of south glass
  • Use stone,brick,concrete block(filled),white oak and adobe but become useless if covered with carpet
