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
