Passive solar design features include:

  • Orienting buildings so that north-facing windows (southern hemisphere) allow sunlight to enter living spaces.
  • Using sunlight from north facing windows (southern hemisphere) to heat living spaces when you want to warm a building
  • Using thermal mass (such as masonry walls and concrete slabs) to regulate internal temperature variations.
    • In summer, thermal mass can keep a building a cool duing hot days (if you keep the sun off it)
    • In winter, you can allow thermal mass to warm up in sunlight so it can give off heat during the evenings
  • Using shading systems to keep sunlight away from North, East and West facing windows when you want to keep a building cool

In the northern hemisphere, south-facing windows get the sunlight.
