Passive solar heating technique can be used in building design in mid by latitude having :

  • A.Large windows facing South
  • B.Large windows facing North
  • C.Small windows facing South
  • D.Windows facing East or West

Answer: A

Passive solar heating uses large windows facing south.

In the mid-latitudes of the northern hemisphere, the winter sun stays low in the southern sky. Large south-facing glazing admits that sunshine, and thermal mass inside the building stores the heat. Overhangs shade the same windows from the high summer sun.

North-facing windows get almost no direct sun in winter and lose heat. Small south windows admit too little energy, and east or west windows receive only low-angle morning or evening sun and are hard to shade in summer.
